UPVC (unplasticized polyvinyl chloride) is a popular material used for windows and doors. A UPVC 3 sliding door typically consists of three panels that slide horizontally along a track. The two outer panels are fixed in place while the middle panel slides back and forth to open and close the door.

Here’s a more detailed description of a UPVC 3 sliding door:

Frame: The frame is made of UPVC, which is a durable and low-maintenance material that resists weathering and warping. The frame is designed to support the weight of the panels and provide a secure seal to prevent air and water leakage.

Panels: There are three panels in a UPVC 3 sliding door, with the middle panel being the one that slides. The panels are usually made of double-glazed glass, which provides insulation and soundproofing. The glass can also be treated with a coating to reduce heat transfer and increase energy efficiency.
