    Home insulation on sloping ceiling - is this ok?

    Is this ok? I ripped down an old lath and plaster ceiling (immedately regretted it) firstly doing an Asbestos Test via online lab - that was clear. Then put insulation straight over joists like this with 48MM thk insulation, and foam glue onto the walls (c. 5mm thk foam bead) : left air gap...

    Unidentified leak

    I've had my loft insulated and boarded recently to turn into a loft room. It's only been 5 months and I now have this brown sticky substance coming out but only in one place. I've cut a hole in the new boarding to see what's going on but it feels quite dry. We have a newish roof without any...

We have an old (150 yr old) log cabin which I am renovating, currently insulating the upstairs. 2 x 4 stud walls with 100mm celotex between studs, VCL, then 50mm Celotex over studs. The walls are very uneven so there is a...

    (yet another) integral garage thread

    I've read a lot of threads like this, but don't think I've found quite my answer yet (which probably just means I haven't found the right thread yet). I've got an integral garage on my 1930s house. The previous owners constructed over the top of it so our en-suite and half of my sons bedroom...

    Ground floor feeling colder after floor 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...

    Cramped and awkward eaves space - best approach for roof insulation

    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...

    Warm or cold flat roof for concrete deck with overhang?

    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...

    Insulation between floors on a 1960s Chalet style house?

    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...

    Can you cut 20mm PIR into spacers to maintain void between 50mm PIR & shed wall?

    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...

    Eves loft storage space - to board or not to board?

    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...
