Independent experts agree; air leakage is the largest contributor to heat loss in homes. Reducing air leakage through airtight construction significantly improves comfort and lowers energy use.
“I’ve known about the technology for a while and seen them work their magic on other projects. The results speak for themselves.”
Wasted energy: Up to 90% of heating and cooling can be lost through leaks.
Uncomfortable temperatures: Draughts, hot and cold spots, and uneven heating.
Moisture and mould: Warm air leaks into walls, causing condensation and hidden mould.
Health concerns: Poor air quality can trigger asthma and allergies.
Inefficient systems: Heating and ventilation work harder in leaky homes—like running your car’s AC with the windows down.
Air sealing reduces these issues—creating homes that are more energy-efficient, comfortable, durable, and healthy.
A house needs to breathe—but it should do so in a controlled, consistent way, not just when the windows are open. In an airtight home with proper ventilation, fresh air can flow continuously without relying on open windows or losing valuable heat. This manages internal moisture, reducing condensation, musty smells, and the risk of hidden mould—creating a home that feels fresher, more stable in temperature, and noticeably more comfortable every day.

Energy efficiency is no longer just about comfort—it’s a key driver in property value and saleability.
Homes with certified energy ratings consistently outperform the market
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 to achieve.
