insulation

Hello everyone. I'm hoping someone could assist me with a bit of a dilemma. Around 2020, we carried out some renovation to our 1930's semi-detached home. As part of the renovation, the whole ground underfloor, which is suspended with a metre or less drop, was insulated with mineral/rock wool...

When I had my loft converted, the builders did not insulate the eaves, just the wall separating the inside of my house from the eaves space. Building control were fine with this. I think the builders did a good job, they just chose to insulate the easier surface (the wall) and at the time I...

Have brick-built barn, which has been previously converted by putting timber studding about 30cm from inner brick wall and covering with Kingspan. 2 of the rooms are at angles to the rest of the building and are much colder, both single story with vaulted ceilings. Both have huge draughts...

We are erecting a steel portal frame 8m x 12m i have positioned the 9 inch treated purlins with small wooden blocks beneath them so I can attach white corrugated tin beneath the wooden blocks will enable the edges of the corrugated tin to slide in, and sit over the i-beams by approximately 20 mm...

Renovating our study in a 1880s Tyneside terrace flat on the first floor. We have come across half brick/ half l&p internal walls multiple times while renovating other rooms in the flat. One (on the first floor) we removed altogether, the other (also first floor) we took out the bricks and...

Hi, I have a single-skin brick extension with a concrete flat roof from the 50s/60s that I’m getting re-covered. The concrete roof overhangs the exterior by 100-150mm. I’m trying to decide whether to go warm or cold roof. I originally thought warm but now I’m concerned about potential...

I removed some of the tiles on the rear tiled section between the ground and first floor on my 1960s Chalet style home to remove an unused old extractor vent. A piece of sarking felt was missing (for the old vent tube), and I could see half way towards the front of the house until an internal...

Hello all, I am currently converting my single skin garage into a useable space, I have already boarded and insulated the ceiling. My next job is putting a timber frame on the wall ( 38mm x 63mm CLS timber ) DPC behind the frame touching the brick, then insulate between the frame ( 50mm...

A question about insulating stud walls. We have a room in the roof, and the eaves space is uninsulated. I have formed an opening into the eaves space (as was sealed off), and I am in the process of rolling mineral wool insulation in between and over the floor joints to insulate the ceiling to...

Hi all, looking to solve my draughty downlight issue in my kitchen – unfortunately the cavity is inaccessible due to a tiled bathroom floor above so I’ve been looking into flexible fire hoods that can be fitted through the cutout from below. Found the conical ones from Thermahood, but at almost...

I'm insulating my shed to use as office. It's quite thick and sturdy, like a log cabin in construction. I'm planning to attached 70mm deep (finished size) stud frame to wall, fit 50mm cellotex (leaving 20mm air gap behind it), then tape and plasterboard. Battens seem to be either 19mm or 25mm...

Am having a hip to gable loft conversion done hopefully this Summer. I've heard in some quarters that the eves cupboard storage space should not be insulated and boarded up in order to allow flow of air. Yet many people apparently have this done, either to avoid drafts, heat loss, or for...

Hi there, Any help here would be appreciated. I have recently bought a converted stable, in my living room I have cupboards and a seat against a solid wall (see below). I want to insulate the wall behind the cupboard. The wall behind the cupboards is very damp and makes keeping the...

Hi I have a top floor bedroom where where at the external corner of the house there is a cold spot and where mould keeps forming. See the thermal image here. How are cavities formed around corners? Any ideas of the next step ? I don't think I can get a camera down the wall cavity that has the...

Hi All, new here so please bear with me. I have recently replaced the flat roof on my brick built shed and am thinking I am wanting to insulate the roof as I am getting condensation on the underside of the roof boards. I have some left over loft insulation, enough to do the job, so was thinking...

Hi I’m hoping to improve the loft insulation of a cold roof of a large wood clad, timber frame bungalow that is currently poorly insulated and struggles with heat retention. It is currently largely single glazed (I’m working on secondary glazing with Magnetglaze Extreme Pro and 4-6mm Perspex)...

I want to insulate my log cabin as economically as possible and would like to keep it warm as much as possible for 6 to 8 hours between 15 to 20 degrees. My log cabin is 4mX4m and the tallest point is 260cm ( 2.6m). So I guess the side walls are 2.4m. it doesn't have studs except on the roof...

Gah, I’m in a pickle. I’m having internal walls and ceilings/flat roof insulated as part of my journey towards getting an ASHP/more energy efficient house. Most of the walls are 1960s build cavity walls, assumed insulated on the EPC. I’ve had an energy consultant and various builders quote...

Hi all. We suffer from a lot of noise in our top floor bedroom. The walls are slopey - directly below the roof. The insulation there looks minimal to me. There appears to be enough space to add further insulation without losing the 50mm gap needed for air circulation. Can I just slide in more...

Hi all, I've just bricked up a old window in single skin outhouse and want to put in 100mm kingspan, board and skim the inside. Could you tell me how long i have to wait before getting cracking with kingspan and plasterboard? As its single skin i thought i could get started quite quickly as it...
