Overview

The aluminum windows and doors of today are a lot better than the older styles of the 1970s and 1980s. One of the biggest advantages of aluminum is that it's very light but still strong. It's durable and doesn't require much maintenance, especially with a factory-baked or anodized finish. If you have windows with unusual shapes, you might consider aluminum because it can easily be manipulated into the shape you need.

However, aluminum doesn't hold heat in well. The thermal conductance of aluminum is high. Thus aluminum windows and doors may not work well in cold climates. Condensation or even frost forms inside the windows/doors and can present a variety of problems.

This problem is very well solved by using a separator/non-conductive material (Thermal Break or Thermal Barrier) between the inner and outer aluminum frames to prevent the temperature transfer through the frame and condensation on the inside frame. There has to be a complete break between interior and exterior aluminum parts; otherwise a thermal bridge will be established, and you will lose heat.

Speaking of the thermal break for aluminum windows, doors, facades, and curtain wall systems, it is scientifically-proven that the best option is extruded insulation strips made of Polyamide 66 (PA66 or Nylon 66) with 25% fiber glass reinforcement. The use of polyamide 66 resins reinforced with 25% glass fiber in the production of polyamide insulation strips makes these components in combination with the aluminum profile, behave similar to the aluminum metal. It can be said that the difference in the coefficient of expansion and the longitudinal contraction of the polyamide strips with aluminum is almost Zero, which makes it possible for Thermal Break profiles to keep their form and shape in a long time and in the face of different temperatures.
