There was never plan to put cables 50mm below a finished surface...electrician wasn't told that we would be adding 40mm. So by the sounds of it if they are not buried deeper to 50mm+ then the insulation is a different issue as the cables simply shouldn't have been out of line if less than 50mm...
Hi,
Hopefully easy one... we have some chases from cables in solid exterrnal 1930s wall and wondered if any issues with covering in PIR (probably glued) and overboarded with plasterboard (probably glued) Without chasing in the cables in with plaster...
see pics attached...
cheers
Hi
Quick one.
Want to insulate upstairs ceilings below loft space as joists only 100mm. Ceilings may have asbestos plaster so would like to cover in c.20mm PIR (foamed or bonded in place, or some screws if not flat enough) then overboard with new pink plasterboard using c.70mm drywall screws...
Hi,
So my builder left the slab exposed for 3-4 months after laying it (badly) on a vastly over running build. So now that roof is on its floor insulation time. Weve had heaters and 3 dehumidifiers running 12 hours a day and overnight sometimes. We scrub slab to remove dark mud, clay etc then a...
do you use tilt fillets? are BC OK with 11.5? as LABC/NHBC etc guidelines say min 15mm @ 40cm joist centres? also where is the Vapour layer there? cant see it lapped up the upstand?
Hi
Hopefully an easy one - hard to find info online.
I am making upstands myself for a new roof extension with skylights. 2 x 1.2x1.7M skylights.
This is my amateur 3D model of the upstand.. shows indication of VCL in yellow lapped up the side above the top deck/insulation/EPDM
and have...
cheers for that. Yes it comes down to quality of weld at the end of the day it seems... You wouldn't consider a bolted plate across the bottom to be worthwhile?
The main query was whether I could/should reinforce with a plate underneath given my questioning the changed design... this is what I still need input on... tho Tony feels its OK. BC just said to me what I thought they would say.. they will just check the joint based on what is agreed in way of...
