Right, I’ve just put grey (painted wood) window frames in my own house. I wanted u-pvc originally, but found the only ones available without a woodgrain effect are made by Rehau – of the two places I tried to get quotes from, neither would sell me them. Apparently they have to give a 10 year guarantee on the windows, but the manufacturers only offer 5 year on the colour fastness. As a result they didn’t want to sell me them and said stick with white. That wasn’t going to work for the look of the house, so I looked at aluminium.
Aluminium cost more of course, and out of nearly every local supplier, only one recommended them for putting in a residential property! There were many reasons for this, the main one being that plastic are better, cost less, so why pay more?
In the end I found out about Accoya, a treated softwood. Think normal wood with all the moisture replaced with vinegar, and that’s basically what it is. Supposedly lasts longer than oak and the paint on it lasts longer due to decreased contraction/expansion.
Make of the above what you will. I wasn’t having white plastic, and say what you want about folk not buying a house with different coloured windows, but my own house looks better than any other on the street…I’m sure anyone else would say the same. And no, I won’t post pics.
