Hi all,
I am replacing the lean to roof on my house extension, to create a vaulted ceiling where the ceiling follows the rafters and I want to install 3 or 4 velux windows. Pitch of roof around 15 degrees.
I was looking at 600mm centers on 47x175 rafters so I could fit 55x118 velux windows between. But I'm now a bit confused as after speaking to velux, as they say the window will not fit with 600 mm centers. They say the window frame requires 40-60mm gap between the frame and rafters, for flashing, insulation etc, and if this is not the case, there is no guarantee on windows, issues with insulation etc.
Can anybody give me any advice please?
Thanks
