Why uPVC?


Polyvinyl chloride (PVC) is one of the oldest developed plastics and has been used extensively in building products since the 1950’s. The big advantages of using uPVC (unplasticised, rigid PVC) as a window material are:
• High thermal resistance
• High mechanical stability
• Abrasion resistance
• High resistance to fire, chemicals andweathering
• High UV resistance
• Non-toxic
• Oxidation resistant
These properties give rise to the main advantages of uPVC and are the reason why over 60% of European homes have uPVC windows and doors.

Ecological Advantages


• uPVC windows are long-lasting and built to withstand demanding climatic conditions.
• Weathering and Aging Resistant – uPVC windows have easy-care dimensionally stable surfaces, even in extreme weather conditions. Enhanced formulas increase resistance to sunlight and heat. Stabilisers are lead-free and harmless to the environment.
• Harmless to Health and the Environment – uPVC profiles are not composed of chemicals considered harmful to the environment, do not emit any gases, are easy to clean, hygienic and non-porous.
• Recycled Material – Recycled uPVC material forms core elements of the uPVC window frame. Conserving resources and reducing environmental impact.
• No Deforestation – the manufacture of uPVC frames does not contribute to deforestation or habitatdestruction.

Economic Advantages


• Energy Efficiency – R-value is the measure of thermal resistance used in the building and construction industry and is measured in m2 deg C/W. The bigger the number, the better the insulation is. With the combination of the uPVC material and multiple chambers in the profile extrusion, the uPVC window frame of today compares favourably with most other systems on the market. In times of global warming and scarcer natural resources, this translates to savings in both heating and cooling costs.
• Good Value for Money – if the whole of life cost, including the energy savings, are taken into consideration, uPVC windows represent a very sound investment.
• Low Maintenance – minimum maintenance is required to keep the hardware in good working order. Cleaning is easy and windows do not require re-painting.
• Increase in Property Value – uPVC windows will enhance any renovation or new home.
• Healthier Homes - warmer, drier homes are healthier to live in, meaning less sick days and lower medical bills.
