uPVC Windows

UPVC windows (also referred to as PVC-u windows) are a popular alternative to traditional windows. They are sturdy and stylish.The 'u' in uPVC stands for 'unplasticised', a rigid form of PVC that lasts so long it gives the product a lifetime service life. uPVC windows are able to withstand high surface temperatures of up to 82oC without defects. This means that long term sunny conditions do not cause the profile structure to break or deteriorate in quality, throughout the life time of your windows. uPVC windows have multi-point locking mechanisms that are integrated inside the profiles systems. Lockable handles are available on both the windows as well as the doors. The material that uPVC windows are made from, is non-combustible, due to its high chlorine concentration, and the use of appropriate compounds. The profile colour will not turn yellow or fade after a few years of use. Frequent cleaning of the windows is possible without any repainting throughout the useful life of the frame, so the maintenance cost is low in upvc compared to wood.

uPVC Window Profile Systems Consist of Polyvinyl-Chloride, Stabilizer, Titanium Dioxide (7%) etc. in order to withstand various kinds of weather condition, ultraviolet rays and rapidly changing weather while the frame structure can slightly expand or contract.

These uPVC profile systems can accommodate any type of glass – including intruder resistant as well as bullet resistant glass. Together with the steel enforced frames, these window and door systems are among the most secure in the world.

uPVC Windows Systems employ a corner welding process to ensure that the window or door corner is completely welded into a single structure; therefore, water is unable to pass through the welded joint. Additionally a double layer of TPE (thermoplastic elastomer) rubber gasket is placed around the sash and the frame to efficiently seal the gap.

In cities with high pollution levels uPVC Windows Systems can withstand any corrosion caused by such conditions.Even in beach area residencies, humid weather is unable to corrode, or damage PVC Windows Profiles.

uPVC Windows Profile Systems are made from ecologically friendly materials (60% rock salt) in terms of less pollutant emissions than wood and aluminium.

UPVC windows (also referred to as PVC-u windows) are good insulators, require low maintenance, and are very cost effective. UPVC windows are a popular alternative to traditional windows. They are sturdy and stylish, and will not warp, twist, rot or discolour.

UPVC is also a hardwearing material, regardless of the elements, and is normally waterproof which will prevent damp and maintain insulation regardless of the conditions outside. Whereas many other windows will absorb rain water, UPVC windows simply repel the elements to keep buildings warm and to keep the cold weather conditions outside. Additionally this means that a UPVC window is likely to have a long life expectancy, leaving you with a less frequent need to replace your windows.
