Install uPVC window in a single skin brick shed

Anonymous user 09/03/2024 - 3.12 PM

Hi. I've got a single skin brick shed in my garden which currently has a wooden framed window with a single pane of glass. The frame is deteriorating and I'd like to replace the window with a used uPVC window. My question is, if I can't find a window of the exact size (taking into account the 5mm gap needed around the window frame and the sill), can I use a much smaller window and somehow pad out the existing brickwork, e.g. with an outer wooden frame, then secure the window through the outer frame and through to the brickwork? If this is possible, are there any pitfalls I need to be aware of, issues with damp, water ingress, etc? Thanks

Are you a tradesperson and able to answer this question?

Providing you ensure that when you fix the timber you are sealing between timber and brickwork there shouldn't be an issue, but make sure the timber is treated and over time you will have to keep treating it otherwise although your window frame will remain good, the timber will start to deteriorate which doesn't overly look good. Plenty of window supplying companies sell mismatched frames, usually nothing wrong with them just made wrong for another customer size wise etc so you can pick them up cheap, look around and you'll bound to find one near the size, you can get frame extenders usually 20mm or 50mm thick to make the frame bigger and usually can pick these up from your local uPVC supplier. Give yourself a 5mm min gap all round for a smaller gap to seal. It's worth noting, if you end up with bigger gaps then as it's a shed just fill with silicone and stick a 20/25mm trim over the gap which will finish off nicely externally and internally.
