Exterior Folding Windows

Exclusively from Win-Dor

As folding doors become more and more popular, some of our customers have asked us if we’d be willing to make a few windows to match their doors. Our response? “Sure, why not.”

Today we use the same proven platform to make our hybrid folding windows as we do for our hybrid folding doors. And unlike other manufacturers who solely use aluminum, vinyl or wood when manufacturing their folding window systems, Win-Dor combines both vinyl and aluminum to offer our customers something truly unique.

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.

The Win-Dor Folding Window Solution

Understanding the limits of both, Win-Dor set out to create an extremely durable, strong, very low-maintenance energy efficient folding window system that we feel is probably the highest quality bifold windows in America.

Our unique blend of strong rigid aluminum framing with a long-lasting, low maintenance vinyl capping and a smaller sill creates a unique combination not available from other manufacturers. And one which is also thermally improved.
