Double and Triple Glazed uPVC windows

Steel enforced uPVC windows provide fantastic properties at great value. The uPVC frames consist of several air chambers that minimise heat transfer and result to outstanding thermal properties. This combination of uPVC and enclosed air also absorbs vibrations and soundwaves of various frequencies, providing fantastic acoustic properties. In combination with the correct type of double or triple glazing, best results for sound-proofing and protection against heat and cold are achieved.

Sustainable Construction Services’ imported range combines the latest technology with high quality materials and sophisticated engineering. Internal steel and uPVC profiles are accurately cut (down to hundredths of millimetres), before the profiles are married. Then the frame sections are bolted and welded together in highly sophisticated manufacturing facilities in northern and western Germany. Basically all materials of the process chain (from raw material to finished product) are made in Germany.

Windows made from uPVC are easy to clean and maintain. Furthermore, the correct window type (especially tilt & turn) will allow you to clean your windows on every floor from the inside of the building. Cleaning is done in minimal time, without high expenses for exterior cleaning services involving specialised equipment, such as water poles, scissor lifts and the like. Surface damage by sunlight is a problem of the past. Due to increased quality, uPVC gains market share in the medium to high end residential market.

uPVC windows mainly differentiate by their frame thickness, quality and stability. This means the thickness of the external frame as well as the windows sash that holds the double or triple glazing panel. Broadly speaking, increased thickness of framing and glazing panel will improve thermal and acoustic properties.

The imported high quality product range of SCS provides 3 major options for frame thickness:

Classic with 70 mm frames, Vision with 76 mm frames and Premium with 88 mm frames
