| UPVC Windows | Aluminium Windows | Wooden Windows | |
|---|---|---|---|
|
Expansion & Contraction of Window profiles can lead to product deformation |
German Tech UPVC windows is manufactured from tropical formulation which makes it durable with minimal expansion and contraction |
Aluminium has very high thermal expansion coefficient as compared to UPVC, leading to product distortion if not manufactured and installed appropriately. |
Wood has inherent property to breathe / absorb moisture / expand & contract, eventually leading to distortion and gaps |
|
Insulation from Heat |
German Tech UPVC windows provides superior insulation to your home from outside heat as UPVC is a poor conductor of heat |
Aluminium (being a metal) is a good conductor of heat and therefore cannot provide insulation from heat |
Wood is a poor conductor of heat, however improper sealing & bending can allow heat to pass |
|
Low Maintenance |
German TechUPVC windows and doors require no painting, only routine cleaning |
Aluminium windows and doors may require periodic maintenance over long periods of usage |
Wooden windows need regular painting and polishing |
|
Low Embedded Energy |
German Tech UPVC Windows and doors are environment friendly as they require very less energy to convert from raw material to finished good. |
Aluminium window and door frames use large amount of energy in conversion |
Wooden windows and doors use tropical hardwoods. |
|
Termite Resistance |
German Tech UPVC Windows and doors are not prone to termites |
Aluminium windows and doors do not attract termites |
Wooden windows and doors are prone to termites |
|
Resistance to Corrosion |
German Tech UPVC Windows do not rust or corrode due to inherent material characteristics |
Aluminium windows are prone to corrosion |
Wooden windows do not rust / corrode |
|
Fade Resistant/UV Resistant |
German Tech UPVC Windows and doors are made of special UV resistant blend and therefore do not fade even after prolonged exposure to sun |
Aluminium windows are typically powder coated or anodized. The powder coating, If not of high UV resistance, shall discolour quickly. |
Wooden windows and doors start fading very soon ; require constant repolishing/finishing |
|
Fire |
German Tech UPVC windows are Self Extinguishing and do not propagate fire |
Aluminium windows have very high melting temperature |
Wooden windows can catch fire easily |
|
Fire Escape |
UPVC windows can allow easy escape in case of fire; due to its lower softening temperature glass can be pushed out of the frame easily |
Aluminium & glass both have high MP and therefore does not assist in easy break away. |
Wood itself can catch fire very easily |
UPVC is one of the most preferred window framing materials across the world and is now gaining popularity in Pakistani market as well due to its highly-efficient performance ratings.
