uPVC02uPVC Windows Guide (India): Why They Dominate New Homes, Cost and Cautions
uPVC is India's best-value window frame: strong thermal and acoustic insulation, corrosion-proof and monsoon-tight, low maintenance. Covers the steel-reinforced multi-chamber profile, heat-warp and UV cautions, glazing pairing, cost ₹250-800/sqft and 20-30 year lifespan.
Aluminium03Aluminium Windows Guide (India): Slim, Strong, and the Thermal-Break Question
Aluminium frames give the slimmest sightlines and largest glass spans, but bare metal conducts heat. Learn the thermal-break question, finishes including marine-grade for coastal homes, cost per sqft, lifespan, IS 1948:2024, and when to choose or avoid aluminium.
Wood04Wooden Windows Guide (India): Teak, Sal, Deodar and the Maintenance Truth

Steel05Steel Windows Guide (India): The Slimmest Sightlines and the Heritage Look
Steel windows give the slimmest sightlines, maximum glass and the heritage Crittall look — but must be hot-dip galvanised and powder coated against rust, then last 60 to 100 years. Cost, climate fit and when to choose steel in India.

The right material for your climate
Salt, heat and rain
Coastal10Best Window Material for Coastal Areas (India): Beating Salt and Humidity
On the Indian coast, salt and humidity corrode the wrong window in seasons. uPVC (high-UV grade) and marine-grade powder-coated or anodised aluminium win; composite is excellent but costly. Avoid bare aluminium and un-galvanised steel, and specify stainless hardware.
Hot climate11Best Window Material for Hot Climates (India): Keeping 45-Degree Heat Out
The window decision for hot inland India. Why bare aluminium needs a thermal break, why cheap uPVC warps at 45 degrees, how SHGC and Low-E DGU glazing matter as much as the frame, and a budget-ranked recommendation under Eco-Niwas Samhita.
Monsoon12Best Window Material for Monsoon Regions (India): Beating Rain, Swell and Rust
In heavy-rain, high-humidity India the enemies are water ingress, swelling and rust. uPVC and coated aluminium win; untreated wood and un-galvanised steel fail. A monsoon guide to sealing, drainage, weep holes, hardware and a budget-ranked verdict.
