The positives and negatives of an all aluminum folding window system
Aluminum is a great material for bifold window systems. It is strong and rigid. It allows for larger sized installations vs. the traditional vinyl bifolding window system. At the same time, there are several drawbacks to a standard aluminum window system. Just like aluminum windows, it eventually corrodes and breaks down. Secondly, aluminum is great at transferring energy. Because of this, an aluminum bifold system will not be as energy efficient.
The positives and negatives of an all vinyl folding window system
Vinyl is also a great material for bifold window systems. Unlike aluminum, vinyl will never crack or peel. It won’t corrode. In fact, vinyl bifold windows require very little maintenance. And just like vinyl windows, vinyl bifolds can be incredibly energy efficient.
But just like its aluminum counterpart, there are drawbacks with vinyl. A bifold window system make exclusively from vinyl doesn’t have the same strength as an aluminum bifold window system. And because of this, the size of the opening is extremely limited, especially for larger residential and commercial applications.
