WiltshireLink Posted September 9 Share Posted September 9 Hi All, Just had our window survey and they are requesting we have all the stone slips fitted before they can measure the structural opening. Getting told different things that this is or not normally the case.. Is this normal? They are Velfac windows. Need to get them on order as the weather is on the move... Any have any other suppliers in the south I could try? Thanks Link to comment Share on other sites More sharing options...
JohnMo Posted September 9 Share Posted September 9 Do your stone slips after, not before. We installed the window to the outside of the ICF, then overlapped the stone slips on to the window frame. Cut the slips to form a neat frame to the window. 2 Link to comment Share on other sites More sharing options...
WiltshireLink Posted September 10 Author Share Posted September 10 (edited) This is what I was expecting but the surveyor is unsisting not for Velfac. He won't order with out it being on. Maybe I need to change suppliers? Edited September 10 by WiltshireLink Link to comment Share on other sites More sharing options...
torre Posted September 10 Share Posted September 10 Sounds like the surveyor could have explained why much better but I think they're right - Velfac windows are fitted with a shadow gap (10-15mm) and the whole visible frame hinges open. See here The gap is needed to give clearance for the frame to hinge within the opening, so nothing can be installed in front of the frame or they won't be able to open! So, the slips will need to be in place first (and will slightly reduce your openings). A cut edge is a good idea to ensure a consistent gap 1 Link to comment Share on other sites More sharing options...

We have only just started the build but been in touch with them 2 years. 1 Link to comment Share on other sites More sharing options...
