Choice of colours and aesthetics |
Can be made available in unlimited colours and finishes. Smooth surface finish also ensures longevity of colours. |
Predominantly available in white, as colour tends to fade after prolonged exposure to sunlight.
Few other colours and finishes available, but not preferred. |
Maintenance |
Needs very low maintenance.
Very easy to maintain, can be done at home itself. |
Needs skilled labour. In some cases, the window may be needed to be removed and taken to the factory as well. |
Durability under Extreme Weather |
No effect of UV radiation. Enables longer product life. |
Selectively absorbs UV radiations.
This leads to colour degradation, loss of gloss, brittleness and visible chalking. |
Monsoon Resistance |
In-built gutter section for drainage of water, making it watertight. |
Special rain tracks needs to be accommodated for drainage of water. Leads to higher cost. |
Resistance to Wind |
Designed to withstand extreme wind pressure.
Ideal for high-rise buildings and large windows (French windows) |
Reinforced with steel due to lower strength of uPVC.
The metal is prone to rusting over period. |
Effect of expansion/contraction |
Expansion gap is not required. No effect on Door and window. |
Can weaken the welded joints if expansion gap is not provided, thereby difficulty in operation. |
Environment-friendly material |
Endlessly recyclable |
Material quality tends to degrade with time and reuse. Harmful chemical emitted during manufacturing process. |
