insulation

Hi Hi wanted to put some new lights up in garage so cut a hole in ceiling and fitted an access hatch thinking I could climb up there however after seeing the timber decided it probably wouldn’t be safe to climb around in there, I managed to fish my cables where i needed so that job was ok. The...

I've been upgrading my loft insulation. 1950s house. I have joists that are about 130mm deep. In between the joists, there was a thin layer of old glass fibre insulation and what looked like rockwool insulation over that. The insulation varied in depth and was ~75mm deep at best, ie at least...

Hi :) I have just bought a house in need of much renovation! One room is flat roof and I am unsure if I need to add any insulation between the rafters or if there is a layer of inuslation above the boards and the space between the rafters is for air flow. Any advice welcome :) Thanks

Hi I have a flat which seems damp, paint peels off the walls, the electric sockets corrode inside. Is the answer to hack off the plaster half way up and inject with chemical dpc? At some point I will probably need to insulate the place maybe internally. I have seen a video that seems to be...

Hi, i'm in a bit of a quandary... I need to lift the boards and insulate my loft to a better standard, I have these options but unsure which is best The joist are 100mm so not much room for thick rockwool. I can either cross lay more 100mm joist with an extra layer of 100mm rockwool then...

Hi, We have a narrow (3m wide) pitched roof extending from the main roof over the kitchen in our old bungalow, most of it looks insulated with the thin black stuff in 1st pic, but there's a 5/6 foot section that is bare tiles (pic 2) quite breezy in the recent storms though we've had no...

Hi All First post here and having read some of the other posts on bay windows, I do have one additional question. The bay window in the front bedroom has a timber frame, with render on the outside and plaster inside. The radiator is on the wall on the bay window - if that makes sense. The...

Given the massive rise in energy bills coming, insulation is going to lead to much bigger savings on energy bills. Yet our loft is low and so I have a rather unusual issue - I can't insulate it to 270mm. I have just a 100mm cavity between the joists in our loft and insufficient height to raise...

After few season on not be able to use the conservatory as too cold on winter and too warm on summer. I`m now exploring the idea of converting the roof into a solid one but not sure what can be done without stripping everything down. This is a Victorian conservatory 3x3mm around 20 years old...

Hi all, I'm currently starting to renovate an ex-council house with a solid wall (2 bricks thick ~22cm, no cavity). I just tore down some very old plasterboard that had suffered water damage, with the wooden battens falling apart. The root cause of the water issue has been fixed right before...

Hi all, I have a 1960s bedroom extension above a very cold garage below, in my 1930s semi. Looks like the people who put the bedroom extension in didn't bother insulating the floor... so it's freezing in winter and no doubt massively leaking heat! The bedroom has stripped and polished...

Hello all, I am planning on taking my single skin utility room back to brick and then sticking 50mm of insulated plasterboard to it with foam adhesive. The room is currently off of my bathroom accessed by an internal door so is very very cold but damp free (only wetness on wall is from...

Hi there I had the rear of my house externally insulated in October. Last week I noticed the wall under my back bedroom window felt a bit damp. My window man came to check it out and said that the drainage holes had been covered over by the new uPVC window cills fitting by the insulation...

Our new house has a fully boarded loft with insulation laid over the boards. We’d like to store things up there without compressing the insulation. I’ve seen loft legs are a common solution if you’ve got joists under the insulation. Given we have boards underneath, are there any other options...

Good evening all, hopefully someone can give me a bit of advice on the following. I'm a Mechanical Engineer by trade but pretty novice when it comes to household stuff, so apologies in advance! We have lived in a house built in approx 1960 for a few years now and have noticed that we keep...

Our bathroom is a single story extension on the back of the house with an uninsulated roof. I'm currently rewiring the downlights and started thinking about insulation (it's freezing in the winter). I thought for a cheap and easy fix, spray a load of expanding foam up there, through the...

Evening all, Firstly, Happy New Year! I’m planning on insulating underneath the floor boards in my living room. 1900s terraced house so adequate crawl space to do from below, plus I don’t want to damage the floor by lifting up. From research I understand best practice is a vapour barrier...

Hi. I need to increase my loft insulation but would like to have the loft converted in a couple of years. What would be the most efficient way to do this, reducing waste if it’s converted? It’s currently boarded, which is useful, so I think I’d rather insulate at roof level. Would PIR boards...

Hi everyone, I'm building a heated garden office with a box profile metal roof. This space will be heated during winter months. I've got 145mm rafters with glass wool in-between. 15mm OSB ontop of the rafters, then Breathable roofing membrane. I've then fixed the metal roof directlu ontop of...
