insulated plasterboard

I'm in the process of insulating a room located above the garage in my house. It has 3 solid brick external walls so gets very cold - I'm installing insulated plasterboard with 50mm PIR (celotex) bonded to 12.5mm board. My plan is to fix the boards using Soudal PB adhesive foam, direct to the...

Hi all I have an old mid terrace property with old uninsulated stone walls. I’m planning on using PIR insulated plasterboard affixed to a 25mm timber batten frame. I was thinking of adding 25mm rock-wool in between the timber battens just for added insulation. However My question is, would...

I've been using various online calculators for calculating u values for wall insulation, however they seem to vary considerably and make massive assumptions. I need to decide how thick insulated plasterboard i install into some bedrooms - my property is a victorian semi detached, 2x brick skin...

Hi, An extension with a flat roof has been built and BC wants insulated plasterboard installed on top of a vcl for the ceiling. The plasterer suggested rather than using insulated plasterboard 35mm (...

Hi This is my first post and a DIY job that is new to me so excuse me for any basic terms that I will use ( still in the learning process).After reading various posts regarding the same project I am undertaking I am well and truly confused. My 1950's house has bay windows, we are renovating...

Hi all. I've read conflicting things about how to do what I'd like to accomplish so thought I'd post my own question as everyone's circumstances are different so here goes. I live in an end-of-terrace circa 1906 property with cavity walls. Both internal and external walls are of red brick...

Hi All, About to start a detached Victorian 3 bed renovation, as usual solid brick walls so no cavity to insulate. It has been a while since I've done some internal wall insulation, previously I've always used PIR on treated battens. I've spoken with Superfoil and they tell me their SF19+...

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 I have bought a couple of insulated plasterboards (Knauf XPS Laminate Plus Insulated Plasterboard Tapered Edge) to go on a ground floor external wall that is cold and it cant be insulated externally. I understand that on ground floors, you need to leave a 10-15mm gap between the bottom of...

After 3 years of being in our house we've finally come to do up the dining room which is an extension built in the late 80s. It's freezing in the winter because it's essentially got 4 external walls - 1 backs onto garage, 2 are external and the other one is the old external wall of the kitchen...

Hi all, I'm new here so apologies if this post is somewhat repeated elsewhere (I can't seem to find the answer). So I am having a full renovation done on my house (walls being taken out, new plaster etc etc.). One of my bugbears in the past has been the outside walls being very cold (i.e. the...

Hi. Somewhat confused Newby looking for advice re insulating walls and ceiling of a single skin brick utility room at the back of a garage, adjacent to kitchen. I assume that this would be classed as a non habitable space so won't have to comply with the U values. We also plan to add either a...

Hi All, Bit of a lurker but thought this would be the best place to ask the questions. Our old (1865) house has a loft room that has always been a room ( i suspect it was servant quarters once). The room now has stairs direct into the room. The room itself has a pitched apex roof with 5ft dwarf...

Hi, I'm planning on insulating a 'single brick' wall in my house. I plan to attach a vapour sheet, wood batten on top and then fix Celotex PL4060 on top. The plasterer will then skim the plasterboard face. Do I need to notify the council before doing this work. The guy at reading council...

I want to convert an attached garage into a utility room, having done quite abit of research on the forum and else where online. I wanted a few peoples opinions/thoughts on it if possible. Being a new build I can only presume that it will have been built with cavity trays in place, so am I...
