Why uPVC? Comparison between Windows2000 uPVC & other traditional materials
Particular
uPVC
Aluminum
Wood
Surface Quality
The surface quality is maintained throughout its useful life.
Anodizing wears out and corrosion sets it.
Requires regular up keeping
Thermal Insulation
Very good, Heat losses are reduced due to wider profile depth & multi chamber section & Low K value
Poor being a metal it has a poor thermal insulation, and high thermal conductivity.
Fair
Fire Properties
Excellent
Poor
Acoustic Insulation
Excellent, the multi chamber sealed cavities and welded corners offers excellent acoustic insulating properties.
Poor, the mechanically Joint corners renders very poor result from Acoustic insulation angle.
Dimensional Accuracies
Excellent, they are factory produced on sophisticated machine hence offer uniform quality control.
Poor, they are fabricated locally, hence poor quality and non uniformity.
Conservation of energy
Require 7.5 times the energy than that required to manufacture pvc.

Preservation of natural forest wealth
Maintenance
NIL
Require regular Painting & Polishing
Durability
Much stronger due to steel reinforcement profile.
Good
Warping
Will not warp, last for a life time.
