FactorsUPVC WindowsAluminium WindowsWooden Windows
Expansion / Contraction Low, due to its inherent properties Medium, due to aluminium's high thermal expansion coefficient High, due to wood's moisture absorption characteristics
Heat Insulation High, since UPVC is a poor conductor of heat & has no gaps for external heat transfer Low, Aluminium is a good conductor of heat Medium, Though wood is a poor conductor of heat, the gaps due to expansion/contraction can allow external heat transfer
Maintenance Low, No Painting is required Low, No Painting is required High, requires periodic painting
Environment Energy to manufacture the finished product Less Energy Large Energy Not Eco-Friendly
Termite & Borer Proofing Not Prone Not Prone Prone to termite and border attacks
Corrosion Resistance Do not corrode or rust Prone to corrosion Do not corrode or rust
UV Resistance High High for anodized aluminium and low for power coated aluminium windows Low, Starts to fade quickly to sun exposure
Fire Resistance High High Low, can catch fire quickly
Window Colors White being the popular, other wood grains like walnut, mahogany are available High Range High Range of colours
Installation Time Ready to fix Ready to Fix High, since windows need to installed and painting follows at site
Noise Cancellation High, since gaps are low Medium, since gaps are low High since gaps developed due to contraction/expansion
