Did You Know?
When I first heard about windows and doors being made out of 'plastic' I was appalled, and wondered what the world was coming to!
I had the feeling that one by one, the values and standards gained in childhood were bei
ng slowly but surely eroded, in a day when the word 'plastic' usually meant 'rubbish'. When I first saw a sample window I have to admit to being prejudiced, and I hated the window before I saw it.
After that I went on for a year or so resisting the requests made from growing customer interest. I would say to my customers: do you really want plastic windows, when look how good and strong these aluminium windows with hardwood frames are!
I put up my hands and I admit that I was wrong, I bowed to customer demand and followed others in the industry doing what was then called uPVC windows and doors.
In a very short space of time I became a follower, and once my eyes were opened and my prejudice was realised, the many benefits of PVC-U over aluminium/hardwood became clear.
PVC-U windows and doors are designed to be fitted directly into the brickwork or other main fabric of the property without the need for a sub-frame. It is partly because of this that the aluminium with hardwood sub-frames are now usually quite a lot more expensive than the PVC-U.
