Hybrid Exterior Bifold Door Technology – Exclusively from Win-Dor

Unlike other manufacturers who solely use aluminum or vinyl when making their bifold door system, we at Win-Dor have combined both materials to offer our customers something special. The best of both worlds.

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. First, just like aluminum windows, it eventually corrodes and breaks down. Secondly, aluminum is a great at transferring energy. Because of this, an aluminum bifold system will not be as energy efficient.

Now, 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 make 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.

Understanding the limits of both, we set out to create an extremely durable, strong and very low-maintenance bifold door system which we feel is the highest quality bifold doors in America.

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