insulation

Hello, I am currently having a rear extension built and have had a warm flat roof installed. It is only now however that I have realised the wall insulation is supposed to carry on up to meet the base of the warm flat roof!! What would be the best way to insulate this gap before plasterboard...

Heya, I want to insulate the ceiling in the bathroom, which is also the roof at the top of the building. Wondering what's the best option or if there's any special considerations for this scenario? Does there need to be a vapour barrier? (or use foil backed plasterboard?) The rafters are 100mm...

Hi Everyone, First time posting here, so sorry if I'm not doing something right.

Hi All, Looking for some guidance. Our property has a side extension with a bedroom above a garage. We've recently topped up the loft insulation and fixed a leaky window which has helped, but the room still has a cold floor (almost like a heat sink) so doesn't stay as warm for long enough...

Hi all, We live in a chalet style house where the bedrooms are essentially in the roof. The bedroom walls are stud with uninsulated plasterboard. The studs are visible from the eaves side of the wall and would seem easy enough to put some flexible batt insulation in here, was thinking wood...

Hi, I'd like to board my loft and use it for storage and I'd like to move my combi boiler from the bedroom to the loft, to gain some space. I'd like to replace the current loft insulation with PIR to gain some height: 191cm is the highest point from the top of the joists to the rafters. I'd also...

Hi all, Recently moved into a house with a window in the loft. It’s in the gable end wall, and other than the glass looking past it’s best, it is great for natural light in the loft space. I’m currently insulating the loft floor and whilst measuring up started to wonder if the area around...

Hi all, I moved into a 25 year old house a couple of years ago and am thinking about future improvements I can make. The house originally had an integrated double garage. This has been converted to a single garage,and a dining room (which we rarely use in the winter for reasons that will...

Hi all (first post), I'm looking at insulating our ground floor bay window and have scoured pages to look for a similar arrangement to ours. The bay window has adjacent 'piers' (walls) at the end of the curve, I'm wondering whether I should/need to also strip the plaster back on these walls as...

Hi all, curious to know if anyone had experience with Dupre Vermiculite limited micafil insulation in the 1980/90s. Noticed a few bag of the stuff in my loft and got it tested to make sure it wasn’t contaminated. Though noticed the standard uk testing isn’t the best. Apparently the company was...

Hi, in a loft cupboard I have a wall that looks poorly insulated. I'm wondering what the easiest and cheapest option is to improve it? I'm a basic DIYer and paying a builder in London to do the job would probably be more expensive than the energy it'll save over 50 years... so I should do...

Hi all, First off - I've read the pinned condensation in loft thread and I reckon that answers my condensation / insulation related questions but have 3 Qs for those more experienced than me! I live in a Victorian terrace and I'm getting issues with condensation damp on my bedroom ceiling and...
