Multi Slide Door Technology – Exclusively from Win-Dor

The Win-Dor Multi Slide Door Solution

Win-Dor makes an innovative, durable, low-maintenance multi slide door system that is considered among the highest quality multi slide doors in America.

Our multi-slide doors are extremely energy efficient with U-Values of .28 or better. (366 glass with argon)

They are also 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. Light Commercial 35 and Light Commercial 25. (see test results below)

They offer a very clean look with a 35/8"x13/4" sash which measures the same as our folding doors. This allows for consistent look when mixing and matching in the same house.

Our 17/8" rollers allow for easy operations when opening and closing.

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