How PC are your PVC windows? By Joe Lynam BBC World Service business reporter One of the biggest revolutions in the look of Britain's buildings in recent years has been in windows.   The British government's efforts to cut energy use in homes has singled out windows for special attention.   All new and replacement windows now have to be double glazed to cut heat loss. Consequently, wooden window frames have given way to PVC framed double glazing, which is cheaper to buy and install than double glazed timber frames.   In fact, wood double glazing can cost up to three times as much as PVC double glazing.   Safe and Sound By REHAU One of the most immediate benefits of choosing uPVC replacement windows and doors is the peace and quiet that they bring. All REHAU window and door systems can radically reduce outdoor noise levels, by having double glazed sealed units and low air transmittance that can bring down the noise levels in your home by as much as a half.   Security for you and your home is paramount with us at REHAU. Our window and door systems are made from only the highest quality uPVC and designed to provide rigidity and strength, and to allow the highest performance locking mechanisms to be fitted.   Our window and door systems all comply with BS7950 and PAS 23/24 standards governing security and are able to achieve Secured by Design certification. They are also approved by the London Housing Consortium and by Birmingham City Laboratories – two of the most exacting public sector specification authorities.
