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.
 

The positives and negatives of an all vinyl folding door system

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.

Every window and door manufactured by Win-Dor Systems is made from the highest quality 100% virgin vinyl available, extruded in either white or beige.  Colors are consistent throughout the products, hardened to stand up to the harshest elements and will never peel, chip or need paint.

White

A variety of popular painted exterior coating options are available.  Each color is bonded onto the vinyl surface and adds an element of heat reflectivity.  All of our painted finishes are scratch and chip resistant, made to withstand the elements and formulated for optimal energy efficiency.

Additional exterior colors are available.  The semi-custom color family of colors may require longer production lead-times.  Please consult the factory for additional information.

Silver (Coated)

WinShield® is a specialty laminate made from multiple layers of durable and highly reflective materials. Each layer adds to its strength and heat reflectivity. The laminate is bonded to the vinyl using a specialized process. WinShield’s unique technology performs incredibly well even in extreme environments. It is virtually maintenance-free, much more durable than traditional paints used by others, and provides a consistent color that can be carried across multiple products reducing variations.
