Technical Aspects

The formulation of uPVC contains Titanium Dioxide, an inhibitor which combats the harmful effects of UV rays in uPVC products. Due to the origination of uPVC in European countries, it required years of further testing and research to perfect the product for the harsh conditions experienced in some areas of Southern Africa. uPVC is guaranteed to endure all weather conditions without warping, corroding or deteriorating in any way. uPVC products also require very little to no maintenance. Our window frames only require cleaning and occasional oiling of hinges and locks.

Manufacturing Process

ASAP-PVC window frames are fusion welded at the corners, therefore requiring no glue or screw joints. Water drainage slots are incorporated into all the profiles and they are reinforced with galvanised steel which significantly increases the strength of the complete unit.

Our frames are designed to accommodate multiple chambers which reduces heat transfer and results in improved energy efficiency and reduced heating and cooling costs. Homes and buildings remain cool during summer and heat is prevented from escaping during the cold months of winter.

Double Glazing

Double glazing is a manufacturing process of windows where the complete window structure is formed by two panes of glass with a space of several millimetres in thickness separates the two panes. Air becomes trapped between the two panes and an insulating layer (vacuum) is formed. In order to ensure that there is no moisture present between the two panes, a drying agent is added before the unit is finally sealed. Double Glazing is an innovative method incorporated in the manufacturing process of our doors and windows in order to improve the energy efficiency of the homes and building in which they are used. Although double glazing is a more expensive option when compared to standard single pane windows, the cost is quickly recovered through heating and cooling bills.

Double glazing is also effective in controlling and reducing the noise factor and is an environmental aid through the reduction of carbon dioxide emissions from homes.

The Process

The glass is cut to the appropriate size that is required for the intended application. The panes are then spaced to create the air pocket between the panes.

A worker then seals the unit completely, creating a fully insulated, damp and weather-proof structure.

The structure is now ready to be fitted into custom-sized frames which can be colour matched to suit any style.

Advanced Locking Systems and Other Features

uPVC windows and doors are extremely strong and durable. All our door and window frames are fitted with tried and tested multi-point locking systems which are highly burglar resistant for increased security.

  • Multi-point Locking Systems on all windows and doors
