If you go for a walk around the average housing estate in Britain, you’ll notice something: more than fifty per cent of homes sport PVC glazing. These plastic-framed windows are everywhere. When you think about it, this is a little strange. How can just one product be so popular among so many people? In most markets, there’s a considerable spread in the type of products that people choose. Just look at the motor vehicle market. Consumers want everything from city hatchbacks to pick up trucks. But in the window space, choices are, frankly, samey. Why? The reasons for the popularity of UPVC windows are many. Unlike the wood-framed windows of old, they offer a plethora of benefits that the average homeowner finds hard to refuse.
