Guide to Upvc Sliding Windows and Doors

Upvc Sliding Windows & Doors are the most common types of Upvc Windows and doors that are sold in the market. They are the most economical type of Upvc Window or Door design you can make and that is the very reason most windows and doors sold are mostly sliding.

The frames of this kind of Upvc Windows and doors remain constant whereas the thickness of the sash changes depending on whether you are making a sliding window or door. In-case of a window sash, the width of the uPVC sash profile is less and in-case of a door sash the width of the uPVC sash profile is more.
