Factors

UPVC Windows

Aluminum Windows

Wooden Windows

Expansion / Contraction

Low, due to its inherent properties

Medium, due to aluminum'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 aluminum and low for powder coated aluminum 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
