TECHNICALThe UV Factor
In Europe where the UV factor is not prevalent, their uPVC powder formulation contains an ultra-violet inhibitor, Titanium Dioxide, of which only 2% is required for European conditions. After several years of conducting stringent tests and experiments by the CSIR to overcome the harsh UV rays experienced in our country, it was established that the Titanium Dioxide requirement was 5%. Therefore for added assurance, the quantity of Titanium Dioxide was increased was to 7%.
We are therefore confident that our product will endure all weather conditions for an indefinite period of time. As a result, the user need not be concerned with warping, rotting, corroding, scraping and painting of the window frames. The only maintenance required is the occasional wipe down of the frames and lubrication of the locks and stainless steel hinges.
We are using the same tested and approved multi-chambered as used in Germany.
Frame Construction and Wind Loading
The largest chamber of
the frame is supported by galvanized steel or aluminium rectangular tubing, giving
it rigidity. The frames can accommodate glass thickness from 3mm
to 20mm. The frames are fusion welded, therefore ensuring that the
chambers in the profile are sealed and remain completely separate to each
The galvanised steel /
aluminium reinforcing is totally encapsulated in the chamber designed to
hold it. uPVC has a memory and therefore seals itself around any self-tapping
screws that enter the profile.
As a result of this
design, the window frame structure provides an excellent insulator for
noise and temperature control, which is often needed for offices in
windows are subjected to cyclonic and adverse weather conditions
testing. These conditions are simulated with winds of up to 240km
per hour, driving rain and time and Ultra Violet acceleration.
