uPVC Profile Framed Doors, Windows and Sliders — Specification

This Indian Standard specifies requirements for the materials, fabrication and performance of complete external doors, windows and sliders made from uPVC profiles. It aims to ensure that such products provide the required performance in buildings, in addition to good appearance, acoustics, thermal properties and view area. The standard does not cover products subject to requirements for smoke leakage, fire resistance or escape routes, curtain walls, revolving doors, internal partitions, or bullet- and blast-resistant doors, windows and sliders.

It lays down requirements for uPVC profiles, aluminium extrusions, protective tapes, glass, hardware and fixing components, reinforcement, glazing gaskets and setting blocks. uPVC profiles are required to conform to IS 17953, while the types, handing and classification of products are linked to IS 18648. Requirements are also given for corrosion resistance of hardware, including enhanced resistance for installations within 1 km of the seashore. Reinforcement must be securely installed and designed to achieve the specified performance.

Construction and safety provisions include multipoint locking for specified doors and larger windows, child-safety window restrictors, anti-fallout devices for open-out windows, and suitable provisions for high-rise buildings and high wind loads. The standard also specifies requirements for drainage and ventilation slots, fusion-welded or adequately sealed joints, mechanical joint strength, setting blocks, dimensions and fabrication tolerances.

Testing, sampling and conformity requirements are provided for the complete system. Each product is required to carry information such as the manufacturer or brand name, applicable performance classification values and date of manufacture or batch number. This also includes requirements for packing and dispatch to preserve alignment and facilitate proper installation.
