Why uPVC?

uPVC is a green material obtained by polymerisation of Vinyl Chloride and has widely been used in the manufacture of doors and windows for more than 4 decades in western countries and since last 2 decades in India. Its insulation property makes it the ideal material for windows and doors in a near Tropical Climatic country like India.

Features of uPVC Windows & Doors

  • Energy Saver
  • Thermal Insulator
  • Termite Resistant
  • Corrosion Resistant
  • Low Maintenance
  • Great contributor to aesthetics
  • Weather Proof
  • Water Proof Material
  • Safe
  • Wind Resistance
  • High Durability
  • Eco Friendly
What is uPVC?
UN-Plasticized Poly Vinyl Chloride is obtained from polymerisation process of Vinyl Chloride – which is inturn obtained from mixing Ethylene with Sodium Chloride (57%- Common Salt).
Is uPVC suitable for India?
uPVC is ideal for Indian Climate which is near tropic and has a high demand for energy conservation. uPVC windows help in controlling the heat coming into the building / home by acting as a insulator. Buearu of Energy Efficiency is working towards Star Rating of windows based on the insulation properties of windows and uPVC windows are a ideal choice as they can offer U value as low as 0.6 W/m2K for high performance casement windows and 2.4 W/m2K for normal Sliding Windows which is much lower than other type of windows (wood, aluminium, steel, etc).
Doesn’t uPVC become brittle or yellowish after some time?
No. Good Quality UPVC profiles are produced from Tropical Blends which have adequate percentage of TiO2 – Titanium Di Oxide which imparts white colour to the profile along with UV / Heat stabilisers which protects the profile from harmful UV Radiation.
How can one be sure that the profile will not turn yellow?
Most companies offer detailed test reports on artificial weathering test conducted on the profile. UWDMA advocates that the profiles be tested for 8000 hours with 7.2GJ Xenon light exposure. Colour variation and impact strength is checked before and after exposure. (please refer to draft standards of UWDMA standards of uPVC Profiles)
How exactly does energy saving happen in a window?
  • The frame and sash material is uPVC which is a non-conductor. It cuts the heat.
  • Frame and sash are multi chamber. It cuts further heat
  • Tight gasket sealing. This helps in preventing leakage through the gap between frame and shutter.
  • Multi-point locking. This ensures that the shutter and frame are locked and sealed properly.
  • Why do we need steel reinforcements?
    Steel provides the necessaryTensile strength to UPVC profile to prevent deflection / deformation against external forces.
    Is uPVC recyclable ?
    Yes UPVC is recyclable. However scrap is not used in profile extrusion to avoid impurities in the main profiles. Recycled PVC profiles are used in auxiliary profiles which are not exposed or add strength to a window. Some of it is used for producing accessories.
    Is uPVC Window Fire Resistant?
    Oxygen Index of PVC is 45 – 49, it means it needs nearly 50% oxygen to continuously burn. Atomosphere contains only around 21% Oxygen. Calcium Carbonate and Chlorine in PVC prevent it from burning and make it self extinguishing.
