Hi, this is my first post! Just wondering if anyone has attempted to install an old code ( M04 or 104 ) window onto a new MK04 Velux Kerb/upstand? Can it be done and if so, are there any tricks to bear in mind? Thanks in advance, Will
It was velux customer service's response that led me here in the first place. I called up and got the full range of answers from 'yes, of course', to 'absolutely not', to 'it requires a bit of fiddling about but it can be done'. I got the impression that the desire to sell me a new window was an important factor in formulating their response! Was hoping someone with some first hand experience could shed some light.
If the customer hasn't bought them, I would make them up yourself or get a shop to make them up. I fitted some Velux upstands a few years ago. Then the homeowner had paid £600 -£700 for a pair which were esentially a sloping box made up of a twin skin of plywood with some insultation between. When fitted still needs to be fibreglassed to make watertight The drawing for the upstands are on the Velux site http://www.velux.co.uk/~/media/mark...el00004 architects ecx-july2014 hires web.pdf
The new upstands have already been purchased and the M04 windows are only a few years old so seems silly to chuck them for near identical MK04s. From that link, it doesn't look like there's any difference at all other than the pane being slightly bigger. Frame and fittings look exactly the same. Might just crack on and see what happens!
There is no difference between windows. Old code 304 / M04, New code MK04 78 x 98 cm frame dimensions (external) http://www.sterlingbuild.co.uk/_sys...documents/VELUX-New-Generation-size-guide.pdf
