Recent years have seen the popularity of thermal break aluminum alloy windows and doors. Aluminum alloy is a metal with high thermal conductivity, which would result in poor thermal insulation when used in windows and doors. A thermal break aluminum window and door, however, breaks the aluminum alloy in the middle and uses rigid plastic to connect the split parts, thereby improving its thermal insulation. When installing thermal break aluminum windows and doors, how should the gap between the wall and the structure be filled?

1. The aluminum windows and doors, as well as the wall panels, are filled with polyurethane foam adhesive and sealed with silicone. This method is more suitable. It addresses the issue of cracks. When using silicone adhesives, attention should be paid to color matching. Generally, white aluminum windows and doors should be paired with white silicone, while champagne-colored aluminum windows and doors should be matched with black silicone to ensure the overall aesthetic effect.
2. Windows and walls are sealed with resin sealant and decorated with paint or wallpaper on the outer layer.
3. There is a wide variety of sealants available on the market, with different types suitable for various joints. Windows and doors should use polyurethane foam sealants, while exteriors should use polyurethane, acrylic, or silicone sealants. Secondary sealing for insulating glass should employ polysulfide sealants, butyl sealants, or silicone sealants.
When the gap between the installed window frame and the wall is less than 5cm, the gap can be filled with polystyrene foam plastic, followed by a waterproof sealant application. This method not only fills the gap but also ensures no water leakage.
Here are the methods for filling the gaps between the thermal break aluminum windows and walls. You can use these methods for future installations of thermal break aluminum windows.
