Energy Efficiency

In an air-conditioned building, windows and glass doors with a low thermal conductive material can reduce the loss of interior energy. The decisive factors of the thermal conductivity are the material of window profile and the selection of glass. The thermal conductivity of PVC is 0.14 kcal/m.hr °C that is 1/1250 of Aluminum (175 kcal/m.hr °C).

UPVC window with multi chambered profile will also reduce the transfer of heat. The K value of uPVC window is 1.4 kcal/m 2.hr °C, and the K value of aluminum window is 16.3 kcal/m 2.hr °C. For example, the K value of uPVC window, glazing with 5mm single pane is 4.5 kcal/m 2.hr °C, but the K value of aluminum window with the same glass is 7.6 kcal/m 2.hr °C. Therefore, uPVC windows can reduce the energy loss over 30%, and is the best ENERGY SAVING option.

Reinforcement

uPVC Windows derive 95% of their strength from reinforcements made of galvanized steel. They are used in chambers of the profile to provide the necessary strength to the window members. Separate sealed chambers in profile and zinc coating on steel bestows longevity to the product during its usage period.

The thickness and shape of the section is designed to provide the necessary functional and performance parameters of window. The usual thickness of steel reinforcement varies between 16 SWG to 20 SWG. The reinforcements are screwed to the uPVC profile at a designed pitch using self-drilling special screws. The unification of the duo renders strength to the window.

Sound Proofing

uPVC Windows are designed using multi-chambered profiles with tight seals. They are the best windows in noise separation. An average sound separation of 22-25 dB in single glazing and 30 dB in double-glazing is achieved.

It brings tranquility and cut unnecessary disturbance. They are especially favored & widely used in Hospitals, Schools and office buildings. Moreover, after a day of hard work, you deserve to go home with best protection from exterior noise.

Water Resistance

Highly weather resistant quality is achieved by anti-ultraviolet and high impact resistant formulation. It can withstand long exposure in extreme weather change under scorching sun, storms, dryness, high humidity. No brittling and quality deterioration occurs in uPVC windows.

Electricity Insulation

uPVC has high electrical insulation which exceeds 1015 ohms-cm. It is absolutely safe from electrical conductivity.

Fire Retardant

Fire tests have shown that uPVC materials, being flame retardant product, will not cause, support or enhance the natural development of fire. Unlike timber windows, the uPVC sections do not support combustion and are in fact self-extinguishing. This quality prevents the promotion of fire spread. For this reason, uPVC window systems offer considerable fire protection.
