So Why Ignore Hidden Air Leaks? Book a Consult New homes can hide the equivalent of one open window in invisible air gaps. Older homes often hide the equivalent of two or three open windows. EnergyTight™ seals them all. The Problem Even high-spec, brand-new homes can leak the equivalent of a window's worthof air — gaps you'll never see, but always pay for. Older New Zealand homes arefar leakier still, which is why they're so much harder to keep warm. Either way, that means heat escaping in winter, warmth building up in summer,and energy slipping away every single day. It also means moisture creeping intowalls and ceilings, creating the conditions for condensation and mould. Noheating system can keep up if warm air is escaping through dozens of hidden gaps and cracks. The problem isn't the heating — it's the building. The good news: these gaps can be found and sealed, in new builds and existing homes alike, without changing how your home is built.

Enquire Now Airtightness Has The Biggest Impact on Heat Loss New Zealand’s older homes represent a major opportunity to improve energy efficiency, health, and durability. Despite being among the most expensive in the world, many public and private homes remain poorly insulated and full of hidden air leaks—leading to wasted energy, condensation, and unhealthy indoor air. Historically, upgrading these homes meant expensive and disruptive renovations. But now, a simpler, more cost-effective approach is available, one that tackles the core cause of heat loss and moisture problems: airtightness. The Overlooked Energy Saver: Airtightness According to research from the IECC and ENERGY STAR, air leakage is the single biggest source of heat loss in homes—more than walls, windows, or ceilings. Yet it’s often overlooked. By improving airtightness, homeowners can dramatically boost energy efficiency without the high cost and disruption of removing wall linings to retrofit insulation. Source: Based on data from a NEHERS presentation, ANSI/RESNET Conference, November 2023 and ENERGY STAR publications. Proven Benefits: The BRANZ Findings BRANZ researchers conducted a real-world study by upgrading an older home to meet current code standards, then systematically improving its airtightness while maintaining a steady indoor temperature of 20°C. Their results were striking: reducing air leakage from 9 to 1 ACH50 cut heating energy use by 50%. When combined with heat recovery ventilation (MVHR), total energy savings reached an impressive 90% The data alongside is from BRANZ Bulletin 698 - Residential Mechanical Ventilation Systems. why... - Published: 2025-06-26 - Modified: 2025-12-23 - URL: https://aero.solutions/find-out-more/ Browse all resources Aero is the sole agent of AeroBarrier across New Zealand and Australia .

A modest investment in airtightness and ventilation transforms comfort, health, and energy performance. Mould and mildew are common, contributing to some of the worst respiratory health stats in the OECD. Traditional upgrades like removing wall linings to install insulation are costly and highly disruptive. The EnergyTight™ Retrofit Solution makes it easy to significantly improve energy efficiency and comfort in existing homes. Energy use Note: Every home is different, and while EnergyTight™ aims to deliver excellent results in both new builds and retrofits, outcomes depend on many factors—read our full disclaimer here to learn more. Improving airtightness and ventilation is a low-cost, low-disruption way tosignificantly improve a home’s comfort, health, and energy efficiency. Instead of removing wall linings to install insulation, the EnergyTight™ approachfocuses on sealing air leaks and adding heat-recovery ventilation, deliveringgreater overall performance at a fraction of the cost and disruption. Based on IECC data, traditional insulation and window upgrades can reduceenergy use by around 60%, while airtightness, ventilation, and windowimprovements can achieve reductions of around 67% — with walls left intact. If you are renovating, airtightness and ventilation are an essential part of theproject. Without them, major renovations can still result in cold, damp homes,while a modest additional cost delivers a clear step-change in comfort, health,energy efficiency, and durability.

No alternative building systems required. Set target airtightness in design model and use with standard, familiar construction processes and systems. Find out more Pragma Homes - Verified Airtightness Results Pragma achieved the airtightness levels required for Homestar using a simple, low-cost AeroBarrier approach that integrated easily with standard construction practices. Performance was independently verified by BXG through blower door testing, providing confidence in the result. Typical airtightness costs were around $3,000–$4,000 per dwelling, with alternative systems typically costing three to four times more to achieve comparable outcomes. Learn More “We were able to hit all our Homestar targets. We’re pretty stoked about how it came out. ”Liam Pugh, Senior ESD Consultant, BXG Cost reduction through airtightness Setting airtightness targets at the very start of the design process in ECCHO energy modelling creates a powerful opportunity to value-engineer the entire specification. As shown in the screenshots, improving airtightness from the default 5 ACH50 to a modeller-set target of 2 ACH50 reduces heating demand from 45. 1 to 38. 7 kWh/m² and electrical demand from 39. 7 to 36. 4 kWh/m² with the same set of other specifications. This uplift in building-envelope performance allows Homestar targets to be met with less reliance on higher-spec or higher-cost measures—such as upgraded glazing, extensive thermal breaks, slab-edge insulation, or additional loft insulation. By improving performance at the envelope level first, airtightness unlocks simpler, more cost-effective solutions across the... - Published: 2025-06-25 - Modified: 2026-08-10 - URL: https://aero.solutions/typical-applications/ ENERGYTIGHT™ Typical

In new builds, airtightness is essential for energy efficiency, comfort, and durability. AeroBarrier simplifies the process by sealing gaps and cracks throughout the building envelope, allowing builders to meet airtightness targets without complex detailing. Specifiers can document compliance more easily, and homeowners enjoy warmer, drier, and healthier indoor environments with significantly lower energy bills. Solar Panels & Net Zero Energy Homes EnergyTight™ is a Game changer for Feasibility Improving airtightness is a game changer for solar panel installations. Reducing air leakage to 3 ACH50 or less can significantly lower the number of solar panels needed to offset energy use. For those aiming for Net Zero Energy, achieving airtightness of 1. 5 ACH50 or less means the energy demand drops enough that a smaller solar array can fully power the home—making Net Zero Energy both practical and cost-effective. AeroBarrier helps builders and homeowners create homes that require fewer solar panels to achieve the same energy outcomes. This not only reduces installation costs but also accelerates the payback period for solar investments. Multi-Unit Developments & Apartments Simple Energy Efficiency Gains Achieving consistent airtightness across multiple units is challenging, but AeroBarrier automates the process, providing repeatable, verifiable results.

No new systems, no new methods—just better outcomes. You can feel the difference. Request A Consultation Air Control: A home that breathes... All the time Air control isn't about sealing a house shut — it's the job of the building envelope to manage how air moves. When the envelope leaks, energy is lost and moisture is carried into walls and roofs, causing condensation and mould. Airtightness and ventilation work together so the home breathes continuously - not just when windows are open. https://player. vimeo. com/video/1170134632 What Is the EnergyTight™ Solution? The EnergyTight™ Solution is a practical, whole-home approach to improving build quality. By creating an airtight, well-ventilated building envelope, EnergyTight™ reduces energy use while improving comfort, indoor air quality, and moisture control.

Other countries, including the USA, UK and Europe, more commonly employ airtightness as a measure of building performance, but New Zealand building codes are lagging in this area (although performance standards such as Homestar are more aligned). At Aero, we’re on a mission to transform the way people think about the building envelope, and this CPD session is an important part of that. Book CPD presentation Why is airtightness important in New Zealand homes? Poor airtightness is a major issue in New Zealand homes, contributing to high energy costs, mould growth, and respiratory diseases. 48% of New Zealand homes suffer from mould, and respiratory illnesses cost the country over $7 billion annually.

Return to home - Published: 2024-07-10 - Modified: 2025-07-16 - URL: https://aero.solutions/faq/ Resources FAQS FAQ’s How does it work? AeroBarrier is an interior applied air sealing system that seals building envelope leaks up to 1. 3cm. The waterborne sealant is aerosolized and injected into a pressurised home. The sealant is self-guided to the edges of visible and invisible leaks to create a seal by accumulating across the leak surface. The sealant is applied within 60-90 minutes and dries quickly, before system cleanup is complete. This ensures construction can resume shortly after the process is complete with little to no impact on standard construction schedules. The AeroBarrier system measures envelope leakage in real-time, enabling the system to dial-in specific air leakage requirements with precision and guarantee the results. How is leakage measured? The AeroBarrier system uses a modified blower door to measure envelope leakage during the process. The blower door is calibrated to meet ASTM Standard E779, E1554, CGSB-149. 10-M86, EN 13829, ATTMA Technical Standard 1, NFPA 2001, RESNET and USACE. What is a modified blower door? AeroBarrier modifies its blower door by adding a heater onto the fan. This allows the system to achieve optimal room temperature and humidity during the sealing process, allowing more sealant to be sprayed into the space for a faster, more efficient sealing process. What size leaks will this seal? AeroBarrier seals holes as large as 1. 3cm, and as tiny as a human hair. Aerosol sealing is extremely effective at sealing narrow gaps and extremely small holes that are typically not cost-effective to seal manually, or... - Published: 2024-07-10 - Modified: 2026-08-24 - URL: https://aero.solutions/contact-us/ Get In Touch.

Value Engineering Energy modellers can leverage increased airtightness to value engineer their designs by optimising the balance between upfront costs, energy savings, and compliance with energy standards. Here's a step-by-step approach on how to achieve this: Energy modelling: Use energy modelling software such as ECCHO and NatHERS to simulate building energy performance under different airtightness scenarios and identify key improvement areas. Optimise materials and design: Select cost-effective materials and construction methods that enhance airtightness and integrate improvements with other building systems for optimal performance. In many cases, specifications, costs and complexity of other systems can be reduced because a higher level of airtightness is being delivered Airtightness testing: Perform blower door tests during construction to validate airtightness levels and make necessary adjustments to meet energy performance targets. Lifecycle, Quality and Compliance Focus:Consider long-term benefits like reduced maintenance costs, and align strategies with broader sustainability goals. Increased airtightness significantly improves moisture management and thereby reduces structural damage and improves the healthy quality of the air. By following this approach, energy modellers can effectively use increased airtightness to create cost-effective designs that meet or exceed energy standards, providing both immediate and long-term benefits. AeroBarrier makes it simple to achieve the target energy level and provides a certificate documenting the airtightness level at the start of the process and final airtightness achieved. The NZGBC recognises the AeroBarrier certificate as a valid airtightness test certificate.

Resources Videos Why Airtight Homes Use Less Electricity AeroBarrier Explained Enquire Now How AeroBarrier Creates a More Energy-Efficient HomeAirtightness plays a key role in creating an energy-efficient, comfortable home. In this video, Mandalay Homes explains how uncontrolled air leakage allows heating and cooling to escape from a home, increasing energy use and reducing comfort. AeroBarrier helps solve this problem by sealing hidden gaps and air leaks throughout the building envelope. Applied inside a pressurised home, the airborne sealant finds and closes small openings that can be difficult to identify and seal by hand. The result is a tighter home that retains conditioned air for longer, reduces heating and cooling demand, and provides a more comfortable living environment for the homeowner.

Resources Videos Featured on TVNZ Breakfast Putting Airtightness to the Test Enquire Now Aero Airtightness Demonstration | Featured on TVNZThis 145-year-old Castle Street flat in Dunedin was selected by Aero Solutions as a demonstration of how airtightness can improve the performance of existing New Zealand homes without the cost and disruption of a major renovation. Aero used its air sealing solution to target hidden gaps and draughts throughout the building, reducing air leakage from around 16 air changes per hour to under two. Representatives from the New Zealand Green Building Council attended to observe the demonstration and see the results first-hand. The project was also featured on TVNZ’s BNZ Business Breakfast, highlighting the wider issue that New Zealand has no mandatory airtightness standard for homes. Airtightness works alongside controlled ventilation to create a healthier indoor environment. Houses and people both need a constant supply of fresh air, not only when a window happens to be open. By combining airtightness with ventilation, fresh air can be introduced continuously and in a controlled way, 24/7, while reducing uncontrolled draughts and helping the home retain heat.

Choosing airtightness improvements over insulation upgrades in these specific cases shows how measurable performance gains can be achieved quickly, cost-effectively, and with minimal disruption to tenants. How Trust House used airtightness to improve community housing Minimising the cost of upgrading older houses Many older community houses in New Zealand are draughty and hard to heat, and the two buildings that were selected for this project were no different. Trust House had initially considered retrofitting blown-in wall insulation alongside window sealing and mechanical ventilation. However, this approach would have required drilling multiple holes into walls, and then repairing and redecorating internal surfaces. "As a community housing provider, we assess each property individually to determine which interventions will deliver the best value and outcomes. ” says Kenny Gilbertson, General Manager Building and Infrastructure at Trust House. "These houses didn't need full internal refurbishment or redecoration, so we decided to focus on improving airtightness over insulation in this particular case. "AeroBarrier could improve thermal performance without the remediation work associated with traditional insulation retrofits. “Brick houses generally have deeper cavities that insulation has to fill as well, which makes AeroBarrier more cost-effective in this scenario. ” Why airtightness matters in retrofit projects “Airtightness is important whether it’s for a retrofit or... - Published: 2026-06-22 - Modified: 2026-06-22 - URL: https://aero.solutions/blog/article/600-unit-multi-family-development-goes-solar-using-aerobarrier/ - Categories: All, Case Studies  See how Aeroseal's AeroBarrier technology helped a 600-unit solar-powered apartment development in Utah achieve sub-1 ACH50 air tightness, cut HVAC costs in half, and deliver a 150% ROI through utility rebates.

Retrofitting airtightness upgrades mid-construction Building work was fully underway on a residential development with 45dwellings, when the Pragma Homes project team discovered issues around meeting the required thermal performance for the desired Homestar rating. Kent Morgan, Project Manager at Pragma, says: “When a job is not tracking to meet Homestar onsite, it creates pressures in regards to schedule. And on a multi-unit build like we were doing, it affects the entire build programme. ”A redesign and change to the construction method was not an option.

It provides a practical snapshot of how new homes in New Zealand are typically performing. Resources Aero Study Report Typical airtightness of new homes in New Zealand. Aerobarrier case study Aero Study Report Typical Airtightness and operational leakage of New Homes in New Zealand Outline Background This report summarises airtightness results from new-build homes completed last year. It provides a practical snapshot of how new homes in New Zealand are typically performing. The sample includes production builders as well as those aiming to deliver above-Code homes. The builders in this sample are generally more aware of airtightness and actively working toward better outcomes. As a result, the pre-airsealing results in this report are likely to be somewhat better than the wider industry average. Understanding Airtightness Airtightness is measured in air changes per hour at 50 Pascals pressure difference (ACH50). The lower the number, the tighter the building and the less uncontrolled air leakage occurs. The scale below shows how different performance levels relate to real-world outcomes. The older New Zealand homes Aero has sealed sat in the ‘Poor’ zone, leaking at over 20 ACH50 due to construction methods - very hard to heat and likely unhealthy to live in. Aero has taken old houses from above 20ACH50 to below 5ACH50 through improved airtightness and ventilation retrofits. New homes in the sample, performed on average at around 6–8 ACH50 - still well above IECC code minimum standards. Homestar and Passive House homes, sit in the ‘Best’ range of below 3 ACH50.

Airtightness reductions of 40–70 percent lowered ACH50 from typical pre levels of 4–8 to post levels of 1–3. These changes delivered consistent heating energy savings of 15–30 percent, equivalent to 8–25 GJ per home per year. Energy savings scaled closely with ACH50 reduction, with the largest gains in homes starting above 5 ACH. Results align with building physics theory and show strong relevance for New Zealand housing, where baseline leakage rates are high. Highlights Airtightness gains delivered 15-30 percent heating energy reductions across measured homes. Leakage cuts of 40-70 percent shifted homes from 4-8 to 1-3 ACH50. Each 1. 0 ACH50 reduction saved 4-10 GJ or 5-15 percent heating. Savings were strongest in leaky homes above 5 ACH, matching New Zealand conditions.

Pre-intervention airtightness commonly ranged from 4 to 8 ACH50 or higher, with significant builder-to-builder variation. Leakage reductions of 40 to 70 percent shifted homes toward 1 to 3 ACH50, delivering consistent heating-energy savings of 15 to 30 percent, or 8 to 25 GJ per home per year. Energy reductions scaled closely with initial leakage levels, with the largest gains in homes starting above 5 ACH50. Results confirm airtightness as a dominant driver of residential heating demand and a repeatable pathway for large-scale load and carbon reduction, even accounting for normal construction-stage rebound effects. Highlights Airtightness reductions of 40-70 percent consistently lowered heating demand by 15-30 percent across measured homes. Energy savings of 8-25 GJ per year were recorded. Homes starting above 5 ACH50 delivered the largest absolute and percentage savings. Post-intervention airtightness clustered tightly around 1-3 ACH50, demonstrating predictable, scalable performance gains. Measuring the Energy Impact of Airtightness The Canadian utility study evaluated the relationship between airtightness and heating energy use across a large sample of new homes built by multiple production builders.

Both studies identify significant pre-construction variability in air leakage and demonstrate consistent post-intervention reductions of 40 to 70 percent, with final airtightness levels typically between 1 and 3 ACH50. Heating energy savings ranged from 8 to 25 GJ per year, with proportional reductions in fuel consumption and greenhouse-gas emissions. Savings scaled with initial leakage levels, and performance variability narrowed following intervention. The alignment of results across datasets provides strong empirical evidence that airtightness improvement is a reliable, scalable strategy for reducing residential energy use and emissions. Highlights Pre-construction airtightness varied widely, typically 4 to 8 ACH50, confirming envelope inconsistency across production housingSealing interventions reduced leakage by 40 to 70 percent, with post-intervention values clustering between 1 and 3 ACH50Heating energy demand declined by 8 to 25 GJ per year, equivalent to 15 to 30 percent reductions in most homesResults were consistent across two independent utility datasets, supporting scalability and policy relevance Utility Evidence on Airtightness Performance Canadian utilities have increasingly focused on airtightness as a controllable and quantifiable component of residential energy performance.

Find out more The Research Is Clear: Moisture Control Needs More Than Code Compliance Across New Zealand, many homes meet official requirements yet still struggle with hidden dampness. The reason is simple. Condensation does not care about paperwork. It is the result of physics, materials science, and everyday living patterns. When warm indoor air meets a cold surface inside a wall, ceiling, or roof build up, moisture forms. If this moisture cannot dry fast enough, it stays in the structure. Over time insulation becomes less effective, timber begins to decay, linings fail, and indoor air quality declines. The code sets the minimum standard. Research from building scientists, including the team at BEO Science, as documented by Denise Martin in her Condensation Analysis article, shows that minimum standards do not always prevent long term moisture problems. If your goal is a building that stays healthy across decades, you need a deeper look at how heat and moisture actually move through the assembly.

The building envelope is the protective shell that separates the inside of your home from the external environment. It includes the walls, roof, floor, windows, and doors, essentially everything that encloses the interior space. A high-performing building envelope plays a critical role in maintaining thermal comfort, reducing energy use, and protecting the structure from moisture and pollutants. In New Zealand, Aero is the specialist when it comes to airtightness, offering expert assessment and solutions to improve the performance and integrity of the building envelope. The Two Key Control Layers Within the building envelope, there are two main control layers that perform distinct and complementary functions:1. Weathertight Layer This is the home’s outer defence against the elements. It protects the interior from wind, rain, snow, heat, cold, pollen, and other outdoor pollutants. Common components include roofing, cladding, windows, flashing and sealants’. 2. Airtight LayerThis internal layer keeps the inside air in—and the outside air out—unless deliberately ventilated. The interior lining includes the continuous layer formed by the walls, ceilings, floors, windows and doors. It:Reduces heat loss and energy billsControls indoor moisture from daily activities like cooking and washingProtects against mould, mildew, and interstitial condensationEnhances indoor air quality and thermal comfort The airtight layer can be located on the interior lining (e. g. , wall linings and windows) or exterior lining (e. g. , rigid air barriers), but in either case, its continuity is essential.

Resources Articles Airtightness and H1 A Simple Fix to Reduce Compliance Costs Enquire Now Clause D. 1. 13. 1 is limiting the effectiveness of H1. The building code is out of balance and the industry is seeing the consequences. The Problem Hidden in the Code New Zealand’s H1 clause is designed to support energy efficiency in buildings, but in practice, it has become narrowly focused on insulation and windows. One of the most powerful tools we have for improving performance — airtightness — is currently locked out of the compliance pathway. This is due to a technical restriction in Clause D. 1. 13. 1 of the H1 Verification Method, which states: “Infiltration assumptions for the proposed building and the reference building shall be the same... ” The result? Even when airtightness is measured and proven via blower door testing, it cannot be modelled as part of energy compliance. That restriction is skewing the entire H1 system. H1 Is Out of Balance The three main drivers of building envelope energy efficiency are:Airtightness – sealing gaps and reducing uncontrolled air leakageInsulation – in walls, ceilings, and floors to slow heat flowWindows and glazing – to manage heat loss and gain through joinery and glazingThese elements have roughly equal impact on a building’s energy performance and all three must work together.

Resources Articles Airtight Retrofit Solutions: Transforming Old Homes Without the High Costs. Enquire Now The Hidden Potential in Existing Housing Stock New Zealand’s older homes represent a major opportunity to improve energy efficiency, health, and durability. Despite being among the most expensive in the world, many public and private homes remain poorly insulated and full of hidden air leaks—leading to wasted energy, condensation, and unhealthy indoor air. Historically, upgrading these homes meant expensive and disruptive renovations. But now, a simpler, more cost-effective approach is available, one that tackles the core cause of heat loss and moisture problems: airtightness. The Overlooked Energy Saver: Airtightness According to research from the IECC and ENERGY STAR, air leakage is the single biggest source of heat loss in homes—more than walls, windows, or ceilings. Yet it’s often overlooked. By improving airtightness, homeowners can dramatically boost energy efficiency without the high cost and disruption of removing wall linings to retrofit insulation.

If you want a home that performs well year-round, start with airtightness. Resources Articles Airtightness: The Key to Energy Efficiency and Everyday Comfort Find out more Building scientists have long recognised airtightness as one of the most important drivers of both energy efficiency and indoor comfort. By cutting down on unwanted air leakage, airtight homes stay warmer in winter, cooler in summer, and healthier all year round—while also reducing running costs. When paired with proper ventilation, airtightness not only saves energy but also delivers consistent comfort and long-term durability, making it a cornerstone of high-performance building. It all starts with airtightness Airtightness is the leading factor in achieving energy efficiency in home design, construction, and renovation. In countries like the USA, UK, and across Europe, minimum airtightness levels are mandated by building codes to meet energy performance targets. That’s because airtightness is widely recognised in building science as one of the most effective ways to reduce energy loss. Globally respected standards, such as IECC and ENERGY STAR reinforce this.

Aiming for Passive Home standards after the project has started? Here’s how Aero helped do just that! When Auckland’s Respond Architects heard that their client wanted to achieve Passive Home standards for a multi-dwelling development in Auckland’s Mangere Bridge not just after it had been designed, but after the build had started, Aero stepped up. An extremely high airtightness level of 0. 6 ACH is central to Passive Home certification. For that reason, architects and builders aiming for the rating consider airtightness from the start – long before the first concrete is poured. Even with the challenges involved, developer Jasnish Gujral of Nest and Invest says it was the increased comfort and quality of living that convinced his team to make the shift to Passive House. “We said yes, let's upgrade our building and see if we can give buyers the best living conditions possible. ” “Let's upgrade our building and see if we can give buyers the best living conditions possible. ”Jasnish Gujral, Nest and Invest “When the client became interested in aiming for Passive House for this project, we sat down and talked to them about the certification, the benefits and how to achieve it,” Respond Architects explain. “We then did the energy modelling for all 15 units to determine how we could achieve this. ”While modifying the existing design and build plan to achieve the higher standard worked on paper, reality didn’t quite match up.

Learn how Lyndhurst St Townhouses achieved Homestar 6 with ease and reduced energy demand by up to 22%. The AeroBarrier Air Sealing System was used to quickly and easily bring airtightness below 2 air changes per hour for the three townhouses. Located in Wai o Taiki Bay in Auckland, this medium density rental development features three 107m2 townhouses which were designed to aim for Homestar 6, version 5. Ensuring airtightness of less than two air changes per hour (2 ACH50) for each of the three homes was an important step in helping the homes to achieve the lower space heating demands required under Homestar. Specification of the AeroBarrier Air Sealing System ensured accurate measurement of airtightness, efficient sealing of air leaks, and an impressive end result of between 0. 76 and 1. 2 ACH50 for each of the three homes. Initially, the homes were designed as standard under 3604, but after learning about Homestar the client decided to aim for Homestar 6 to futureproof the homes and increase the overall energy efficiency and sustainability of the development. With the need to bring the original design up to Homestar 6 Standards, Nuline Homes, the contractors for the project, contacted Environmental Building Services Providers, BXG, who have carried out the energy modelling for the project. "AeroBarrier achieved exactly what we needed to achieve. We got down to the right amount of air changes for Homestar 6. We couldn’t ask for better. ”Nick Allan, Builder and Director, Nuline“The homes were not designed for Homestar from day one, so when it came to design, it was a retrofit style airtightness model,” explains... - Published: 2024-09-25 - Modified: 2026-06-22 - URL: https://aero.solutions/blog/article/aerobarrier-testimonial-8/ - Categories: All, Case Studies , News & Events, Videos Stage 1.

Millions of homes were built before Australia introduced housing energy efficiency standards in 2003. They’re leaky. Gaps around windows, doors and between building materials allow air to move in and out. So people tend to compensate, with more heating and cooling. It’s costly and damaging for the environment. Using a national sample of 102,000 Australian homes across all 69 climate zones, we identified the most common housing types. Then we worked out how to make them “climate ready” and what benefits would flow.
