Folding Door Technology – Exclusively from Win-Dor

Unlike other manufacturers who solely use aluminum, vinyl or wood when manufacturing their folding door systems, Win-Dor has combined both vinyl and aluminum to offer our customers something special.

The positives and negatives of an all aluminum folding door system

Aluminum is a great material for bifold door systems. It is strong and rigid. It allows for larger sized installations vs. the traditional vinyl bifolding door system. At the same time, there are several drawbacks to a standard aluminum door 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.

Vinyl is also a great material for bifold door systems. Unlike aluminum, vinyl will never crack or peel. It won’t corrode. In fact, vinyl bifold doors 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 door system made exclusively from vinyl doesn’t have the same strength as an aluminum bifold door system. And because of this, the size of the opening is extremely limited, especially for larger residential and commercial applications.
