3750 Sliding Door Technology 
Exclusively from Win-Dor

Win-Dor's innovative, durable and low-maintenance sliding glass door system is considered one of the best values in America. The highest quality at a fair cost.

Our sliding glass doors are extremely energy efficient, very strong and structurally sound. Our unique blend of rigid aluminum framing with a long-lasting, low maintenance vinyl capping creates a unique combination not available from other manufacturers.

They offer a very clean look with a 3 3/4" x 1 3/4" sash which measures the same as our multi-slide and folding doors. This allows for consistent look when mixing and matching systems in the same home.

Our 17/8" rollers coupled with our extruded track system allows for easy operations when opening and closing.

All of these features add up to a door that clients love.

And regarding performance, you can see the Performance and Testing results located in the technical section.

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.


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.
