UPVC Windows and Doors Guide: Multi-Chamber Profiles, Steel Reinforcement, Double Glazing, Sealing and Drainage, Colours, Hardware, Indicative Rates Per Square Foot, Installation and Quality Checks in Pakistan
UPVC windows and doors are made from rigid plastic profiles with a steel core, and they are popular in Pakistan because they insulate, resist rust and termites, seal well against dust and need little maintenance. Prices run from about PKR 900 to PKR 2,500 per square foot. This page covers multi-chamber profiles, steel reinforcement, double glazing, sealing and drainage, colours, hardware, indicative rates, installation and quality checks. For related pages see UPVC doors, aluminium and glass doors and soundproof doors and windows.

Profiles and steel reinforcement
A good profile has multiple chambers for insulation, walls of at least 2.5 to 3 millimetres and a galvanised steel core in larger frames, since plain plastic bends under heat and wind. Ask for the wall thickness and the number of chambers.
Glass
Double glazing with a 12 to 16 millimetre gap cuts heat and noise, and laminated or tinted glass adds security and comfort. Single glass suits a tight budget, but double glazing pays back in cooling costs. See soundproof doors and windows.
Sealing and drainage
Good UPVC units have gaskets on all sides, welded corners and drainage channels in the frame so rain can escape. These keep out dust, rain and noise. Check the welds for clean, even joints.
Colours and sun
White is standard, and woodgrain foils and colours are available at extra cost. Quality UPVC contains UV stabilisers so it does not yellow. Cheap profiles chalk and fade in strong sun, so choose a maker with a warranty.
Hardware and security
Use multi-point locks, stainless hinges and good handles. Quality hardware keeps windows tight and secure. Fit restrictors where children are present.
Installation and quality checks
Measure the opening, order to size and fix with anchors, packing and sealant. Check welds, gaskets, hardware and a written warranty of 5 to 10 years. Fitting should be done by a trained carpenter or fixer, and the frame and wall checked for level before the door is hung.
What to check before buying

Before you decide
Check profile walls and the steel core, choose double glazing and confirm the warranty. UPVC windows and doors are efficient, quiet and nearly maintenance-free when well made and fitted. Ask for a shop drawing with sizes and keep the hardware details.
