AeroBarrier is applied in a wide range of residential projects, including new builds and renovations.
It’s a simple, cost-effective way to make a significant improvement to homes—enhancing energy efficiency, indoor air quality, and long-term durability.
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.
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.
Achieving consistent airtightness across multiple units is challenging, but AeroBarrier automates the process, providing repeatable, verifiable results. By sealing common areas, shared walls, and floor-ceiling interfaces, AeroBarrier reduces inter-unit air leakage, noise transmission, and energy loss. Developers can streamline quality assurance, and residents enjoy healthier, quieter, and more energy-efficient living spaces.
Passive House projects demand exceptional airtightness to maintain thermal stability and minimise energy consumption. AeroBarrier delivers precision sealing to achieve low ACH targets, reducing heating and cooling loads while enhancing indoor air quality. Builders can achieve the stringent Passive House airtightness standards without extensive detailing, streamlining the construction process and verifying results through blower door testing.
Older residents are more vulnerable to temperature changes and indoor air quality issues. AeroBarrier creates a controlled indoor environment by sealing drafts and preventing moisture ingress, reducing the risk of mould and condensation. This not only improves comfort and health outcomes for residents but also reduces maintenance and heating costs for facility operators.
AeroBarrier offers a cost-effective alternative to traditional renovations by sealing air leaks without the need to remove wall linings to install insulation. By targeting gaps and cracks from the inside, AeroBarrier improves airtightness without major disruption or extensive rework.
For staged retrofits, this approach allows homeowners to achieve significant energy savings and comfort gains immediately—without the expense of tearing down walls. Specifiers can specify airtightness as a first step, paving the way for future insulation upgrades or mechanical ventilation systems.
Independent experts agree: air leakage is the largest contributor to heat loss in homes.
Studies by the International Energy Conservation Code (IECC) and ENERGY STAR show that uncontrolled air leakage accounts for more energy loss than windows, walls, or ceilings.
Reducing air leakage through airtight construction significantly improves comfort and lowers energy use—making it one of the most effective ways to boost home performance.

Air leakage accounts for between 25 percent and 40 percent of the energy used for heating and cooling in a typical residence.
Addressing airtightness is a low-cost, low-disruption way to significantly improve a home’s comfort, health, and energy efficiency. The staged approach outlined below is based on performance data from the IECC 2012.
Instead of tackling the costly and disruptive process of retrofitting wall insulation, addressing airtightness and ventilation first delivers greater overall performance at a fraction of the cost.
Wall insulation can still be added in a future stage. But with AeroBarrier airsealing and mechanical ventilation, Stage 1 already achieves more energy savings than traditional methods—without the disruption.

A certified EnergytightT™ home is a smart investment for future value and long term affordability
When you set an airtightness level, you need to know it’s achievable—and provable. AeroBarrier gives you that certainty. It seals the invisible gaps that are almost impossible to catch manually, ensuring builders consistently meet the specified airtightness targets.
Aero provides a test certificate confirming the airtightness level achieved, so you can sign off with confidence.
An airtight, ventilated home isn’t just more energy efficient—it’s a healthier, more comfortable place to live. Compared to a standard home, it performs better in every way—and costs surprisingly little more.
