Window performance is becoming more important all the time. With the performance comes cost, so the best windows for your home involve performance and value. This is why we have come to promote Alpen Windows and Doors. Alpen is a global leader in ultra energy efficient window, door and glass solutions.

An Ideal Material
Featuring dimensional stability, corrosion resistance and the purity of fiberglass, Alpen’s long-strand pultruded frames maximize insulating power
to create healthy, comfortable and super-efficient homes in any climate—from scorching deserts to the freezing Antarctic. Fiberglass is considered the “greenest” material for window frames, offering durability, better thermal performance and lower embodied energy than vinyl, aluminum or wood
framing materials. It is also practically maintenance free, with an inherent strength and nature that is able to easily distribute impact loads even in
sub-zero temperatures. Fiberglass frames will not suffer the pockmarked surface damage common to wood and aluminum windows and accept paint easily.
