Hi all, just started a large velux conversion, building control have issues with the way i've installed the ashlaring and collars. It's no big deal and i'm quite happy to adjust my methods if incorrect, although i'm puzzled as to why! Just wondered what other people think.. http://i765.photobucket.com/albums/xx292/manicbuzz1/Mobile Uploads/20150424_163258.jpg [Building control say the collars must be attached to the side of the rafters with screws and not cut to fit underneath and nailed] http://i765.photobucket.com/albums/xx292/manicbuzz1/Mobile Uploads/20150422_085546.jpg [Ashlaring must have a top plate] http://i765.photobucket.com/albums/...ploads/20150429_104932_edit_1430757927751.jpg Any thoughts?
Would have to say that up here in God's own country that's how Building Control insist its done. A bit of extra work and takes a little longer but as always get B C on your side and all will be well.
Any loft conversion I have done I have always nailed mine. Best keeping building control happy though as last think you want is to make an enemy with them mate.
Some BCOs will want the collars bolted and the reason for a top plate is to spread any load to avoid point loading.
Just go along with whatever they point out and get it done asap, so the job progresses. Depending on where you are they vary in their zeal and usually have some bee in their bonnet about a certain aspect of work at any one time.
No. Some nail/ bolt the stud to the side of the rafter, other others fit a top plate as in photo above (neater), basically spreads the loading, & not to get point loading with invidual studs.
