insulation

So we've had the hall and landing taken back to brick as the original lime plaster had blown and cracked badly in corners or was hole sounding and was coated with a Chrysotile artex skim that was damaged in places. We had a professional asbestos company do this work a few days ago, who fully...

Hi all, just a quick question regarding insulation. i have to insulate below a bow window board externally but it cant be any thicker than 75mm to be hidden behind the trims. i have an offcut of 140mm celotex. Is it ok to cut this in half so i have two thinner sheets 70mm thick and use it for...

Hello, I'm doing up my loft as in the drawing below. I will be using superquilt on the underside of the rafters down to the wall plate. I will board up a section in the middle with a raised floor. I already have a lot of mineral wool insulation up there which and rather than take it all out want...

Hi Guys, I’m planning on getting external wall insulation (and having the current internal sucked out of our 1930s house as we’re sure it’s causing issues). We’ve had a quote we’re happy with but it doesn’t include removing the old pebble dash render, just making good/removing loose pieces...

I am looking at renovating a 130yr old stone house which currently has lath and plaster internally. Two tradesmen have advised not to insulate and just redecorate but one has said rip out and insulate with kingspan. A friend who has been in a similar situation has advised that heating bills...

Hi, I got a new shed installed and I was wondering about insulating it. Its your basic shed with 2x3 timber frame with cladding over it. I was wondering if I wanted to add insulation to the inside of the shed should I put a breathable membrane to the inside of the shed, stapled to the cladding...

I recently got a shed built after seeing one made by the builder for a neighbour nearby. The one I saw was in good condition and no mould etc. I had the same one built. Wooden frame, concrete floor, plywood and cladding on the outside, GRP roofing and plywood inside on walls and roof. No...

Hi, in the middle of doing a loft conversion and had a question about the positioning of the kingspan in the dormer cheeks and main dormer wall. The dormer cheeks are constructed with 4x2s and the main dormer wall is 6x2. Both finished with plywood and breathable membrane with clay tiles plus...

Hi all, Can anyone help with question. I am laying some new insulation and electric UFH and need to minimise the floor build up. So far I am laying a layer of DPM, 50mm PIR cut to fit and then was planning on placing a 6 mm cement backed tile back board the UFH mat and then tile on that. I am...

We removed the tiles from our window sill and ended up exposing the open cavity. (1959 Bungalow) What would be the correct method to close the cavity and replace the tiles with a wooden window sill? I dont think a cavity closer goes smaller enough to fit in to the void. I was going to: 1...

Moved into my house in past year(60s build) and found that the loft is boarded with insulation (blanket insulation under the boards). I have been thinking that I would like to further insulate the loft and don't really need the boarded area at present. One option would be to pull up all the...

Any views on this mechanism of insulating conservatory roof? Have been looking at replacement roof but perhaps this may be more economical? What are the disadvantages? https://www.insul-8.co.uk/

Hello All. I need advice regarding my loft, specifically insulation under and around the cold water tank. There is a bit of a story to explain everything that has been going on with my loft leading up to this and for that I apologise in advance if it is a bit long winded. Early last year it...

Hi all I hope I am posting this in the right place! I have a small L shaped bathroom (ground floor) in a old building that has no wall cavity. I've had a damp inspection (two actually) which both concluded that the damp I'm getting around the toilet and on the wall next to it is not from the...

Hi, I'm looking to insulate the suspended floor at ground level. There is a 3ft void underneath the floor. I've been looking at using this stuff, https://ybsinsulation.com/floor-insulation/suspended-timber/superquilt-suspended-timber/ I would be installing as show in the attached picture...

Hi, We've got a narrow corridor outside out bathroom, and a rear bedroom as part of an extension which is solid wall and (a) gets really cold, and (2) suffers from damp. The damp problem has been resolved recently by having a PIV system installed, but I was wondering if anyone had any advice...

Hi everyone, our three bed Edwardian is very cold. The upstairs heats with heating but then gets cold quickly once turned off, whilst the downstairs gets warmer (only to about 16 / 17 degrees Celsius currently) and then dips. looking to insulate. We have cavity walls but will not insulate here...

Most people when when upgrading a 1930’s house they think changing the boiler and replacing windows will keep them warmer and save costs on heating but that’s really only going to help so far people don’t realise the cold air under their feet and the pipes under their floor are likely not...
