OPTIMIZING ENERGY EFFICIENCY
With windows and doors made from ALTERA profiles, the heat stays outside the building - thanks to their very good thermal insulation properties. That ensures not only a comfortable living climate, but also lower cooling bills from air conditioning and significantly reduce CO2 emissions.
To ensure that ALTERA window and door designs meet the most stringent energy codes in the United States, we have conducted numerous thermal engineering calculations. Our designs have been simulated using up to 20 different glazing, coating and spacer configurations.
The following chart summarizes the thermal performance of our designs.
Thermal ratings are highly dependent on glass configurations.
Request test reports before the start of any project.
