The Secret Behind Energy-Efficient Aluminum Doors: Thermal Breaks Explained
Follow us
In Quebec’s climate, energy efficiency isn’t just a preference, it’s a necessity. Keeping heat in during long winters and blocking cold air is essential for comfort and reducing energy costs. Modern aluminium doors and windows have transformed from sleek architectural elements, into high-performance components largely due to the integration of thermal breaks.
What is a Thermal Break?
A thermal break is a layer of low-conductivity material, placed between interior and exterior aluminium frames. Aluminium is a strong material, but also highly conductive. Without a thermal break, heat can quickly escape through the frame, reducing the overall energy efficiency of the door or window. By interrupting this conductive path, a thermal break creates an insulating barrier, keeping interiors warmer in winter and cooler in summer.
Adurra takes this a step further by using a foam-filled thermal break, within the aluminium frame. Unlike standard plastic or polyamide thermal breaks, the foam provides superior insulation, filling the frame cavity to reduce thermal bridging and enhance energy retention. This feature is especially important for large openings. Large panels naturally have more surface area exposed to the cold, so a high-quality insulated thermal break ensures that the frame does not become a weak point in energy performance.
Why Thermal Breaks Matter in Quebec
Quebec winters are long and harsh, with temperatures often dropping well below freezing. Even a high-performance glass panel can underperform if the frame allows heat to escape. Thermally broken aluminium systems address this issue, offering homeowners a solution that combines structural strength with energy efficiency.
Adurra's modern systems of doors and windows use multi-chamber profiles combined with high-quality gaskets. This design improves airtightness, and significantly reduces thermal transfers, ensuring consistent indoor comfort. Our systems support larger glass panels, giving you unobstructed views and expansive natural light without compromising thermal efficiency.
Choosing the Right System
When selecting high-performance aluminium doors and windows, it's essential to look beyond glass performance. Thermal breaks play a critical role in the overall efficiency of the system. Adurra's profile systems combine foam-filled thermal breaks, with multi-chamber designs and precision gaskets to deliver superior airtightness, insulation and durability.
