Hi chaps,
I’m using Filon V-Flow GRP dry valley trays (the ones with the 110mn central upstands) on two valleys that meet at the top of a ridge line.
The Filon system includes rubber end trays that allow closing off the bottom of the valley tray, and to act as flashing where they meet at the tops. This is the one for where they meet at the top:
However, I can’t quite get it to sit right. The rubber seems too thick and the way it sits it has a bit of a mind of its own... difficult to explain but there’s the odd gap where it floats up by 5 or 10mm. I don’t really expect it to be a super-snug fit but worry about wind driven rain.
Should it be glued down to the trays in some way, or is the odd uplift okay on the basis that I’ll be covering it with a weight of tiles and ridge tiles and it’ll relax in to place with a few heat cycles?
Thanks
