UPVC windows, are relatively new to India. An ‘unplasticised’ form of PVC, these sturdy window frames have been popular in Europe and America for many years owing to their durability and low maintenance. UPVC windows can withstand extremes of heat, cold, wind, rain and snow without corroding, peeling, chipping or flaking.
Considered an energy efficient choice, UPVC windows have similar thermal properties to timber. UPVC limits the transfer of heat and cold through the frame and as a result can reduce reliance on heaters and air conditioners. These frames can also be filled with foam insulation to further improve thermal performance.
UPVC is a flame retardant material commonly used in fire risk areas. UPVC frames are a self extinguishable material that does not support combustion.
While colour choices may be limited, UPVC can be found in a number of window products, including a variety of traditional window styles: single, double and triple hung windows, sliding, casement and awning windows, picture, bay, bow and garden windows, sliding doors and French door systems. UPVC windows can also be found in such shapes as arches, ellipticals, eyebrows, gothic, trapezoids, rounds and half rounds, octagons, circles, ovals and half-ovals. Lighter colours are more commonly available and will not fade over time like darker colours have been known to do.
UPVC windows and glass doors are constructed in much the same way as aluminium or timber windows, but with a chambered UPVC extrusion forming the frame and glass sash, providing energy efficiency, durability and low maintenance.
UPVC is a new building material, first used broadly during and after World War II to meet many of the critical infrastructure and safety needs of that time. Yet UPVC blends many attributes of traditional materials with the advanced performance characteristics of today’s - and tomorrow's - building products. Durability, lightweight, solid environmental and fire characteristics, versatility and low maintenance requirements are just a few of the properties that have propelled the growing use of uPVC.
