    Insulating intersection of flat roof and vaulted ceiling.

    Yep, they look good and are simple for me to fit (y) So just on to plasterboard - for the vaulted roof and rear wall section as they effectively back on to cold areas is vapour-check plasterboard recommended / required?. I'm using foil backed PIR insulation already but don't want any issues. If...

    Insulating intersection of flat roof and vaulted ceiling.

    Thanks. I was thinking more like below though, which would be very easy to do as it's all easy access. Black squiggle is sealing off the end of the warm roof insulation - my understanding is it needs to be sealed in but hoping to get confirmed. Orange squiggle is linking up insulation to...

    Insulating intersection of flat roof and vaulted ceiling.

    Hi - the existing Alutrix barrier on top of the deck is the specified warm roof makeup - so as not to rely on the PIR alone, apparently it's the norm? but as per the red X in sketch above I've yet to seal that end off - other 3 ends are all sealed up as part of the roof build which was done by...

    Insulating intersection of flat roof and vaulted ceiling.

    Here's where we are at - except I've yet to install the vaulted roof insulation. The red cross is where I'm asking if I need to seal it up so the Alutrix Vapour barrier completely envelopes the warm roof insulation, which is my understanding it should be and keeps it separate from the cold roof...

    Insulating intersection of flat roof and vaulted ceiling.

    Any thoughts chaps, hoping to order the plasterboard in a couple of days. Ta.

    how much damage will a water leak into cavity wall do? 1 litre/hour

    Do you know how long this has been happening? Others here are prob a bit more experienced and hopefully will respond but I'd say as long as you get it fixed reasonably soonish it is unlikely to have caused much long term issues, things should eventually soak away / dry out.

    Insulating intersection of flat roof and vaulted ceiling.

    So if someone could just check I'm on the right track - would love to get this finished for Xmas....summer was the original plan :giggle: 1 - Seal up the end of that warm roof insulation with the vapour barrier - or is there some reasoning in leaving it exposed to that cold area giving it some...

    Ugly fireplace lintel - what are my options?

    I’m thinking wait till the infill bricks are gone and then with the larger space the lintel might sit in better visually. Also in my mind it depends on what else is happening on that whole wall, depending on how busy or sparse it will all be and what you want to be the main features that stand...

    Insulating intersection of flat roof and vaulted ceiling.

    Vaulted roof wasn't in the original plan, was just going to do only the new extension and with warm roof for all the various reasons / benefits.... then when things were underway had the idea of vaulting the roof.
  10. If in doubt...

    Insulating intersection of flat roof and vaulted ceiling.

    Looks like it could be ! So your mitre / angled deck looks like it will take the vapour barrier up to meet the top deck and keep the warm roof insulation self contained?, which I will have do .... either angled or vertically.... dunno if I have the willpower to mitre it all :giggle:. Then is...

    Insulating intersection of flat roof and vaulted ceiling.

    Am just about to start insulating a part vaulted ceiling of the existing bungalow where the warm flat roof of a new extension joins. Below is fairly close to the existing flat roof and proposed set up of the vaulted ceiling (blue rectangle) and it's where the air gap above the vaulted ceiling...

    is this price ok or am I being robbed? (screed)

    My builder recently rough quoted me a grand for 4.5m x 5m x 100mm screed job. I'm SW UK.

    Manky inspection chamber

    Ah makes sense. Looks good. I’ve a combined system and need to run in to an inspection chamber but not keen on putting a complete new chamber in just to include a feed.

    Manky inspection chamber

    Sorry to hijack your thread.... but you did make me open the pic just after having my tea :) but is it normal to bore out the walls for incoming pipes like that? I'm needing something similar but couldn't find anything readily available, but was also concerned doing cutouts might not be reliable...

    Extending ring main and lighting in to new extension

    Well I used to wire control panels for up to 500 kVA generators and nothing ever went bang so I'm not your average DIYer :giggle:, but in the end circumstances have lead me to getting an electrician in anyway - the feed from meter to dist unit is right in the way of some ceiling vaulting work...

    The Caravan Act, yeah right.

    Beam and Block floor finishing questions

    Cheers - there's enough gap to get a decent thickness of insulation in there so I'll go with that. Did initially consider UFH but the room is a tack on to a bungalow and represents less that 10% of the total floor area - and there is unlikely to ever be anymore work done so I felt to introduce...

    Plain tile extractor fan vent

    I recently put on of these in, same kinda job but different design. Faffed around a bit as it was my first one but I'd use again. You do need the adapter supplied separately though...

    Extractor fan

    I might have been unlucky but I put a cheaper (£36) Fantronix 100mm dia inline fan above my shower and within weeks it packed up with no visible issues. Struggled to get going. Replaced it with a more expensive (£70 approx) Manrose fan - and so far so good and seems more powerful although it is...

    Beam and Block floor finishing questions

    Just lining up to slurry, DPM and then insulate and finish a suspended beam and block floor (built by others). Is it best to fill the small narrow gap running the length of the outer beams edges and the inside wall (Cavity wall thermalites) with either mortar or insulation etc. or just leave...
