insulation

Original plan was to use Kingspan but current pricing is a bit ouch so I'm looking at building a 3 x 2 framework parallel to the full brick solid outside walls then filling the void with Rockwool (got a lot of timber and rockwool so those price hikes aren't a big worry). Question- am I ok with...

I am curios if this is doable or would work. I have a small single skin block shed. Now I am wondering if you can use foam tile backer board like Q Board dot and dabbed to the wall as both the vapor barrier, insulation and paneling without using plasterboard? This panel is meant for wet rooms...

Im currently building a garden room but I have a question about the insulation between the wall studwork. Im using 4 x 2 cls24 timber. If I use 100mm pir boards for insulation how do I go about the electrical wiring channels for the cables and sockets? Can i cut into pir boards? Or, should I...

Is it possible to board a loft that has 400mm of insulation? The joists are 120mm high. LoftZone would raise the boards to 404mm, leaving only a 4mm air gap instead of 50mm. Loft Leg XL would raise it to 425mm, leaving only a 25mm air gap. Could I put a block of wood between the joists and...

Hi guys, Hoping for some advice on how I can retro-soundproof my wood workshop. I say soundproof, but what I really mean is limit the sound to a level where my neighbours don't complain! As you can see on the images below, it's a very simple timber-frame shed. It was built to a cost and I...

I've moved into a place with a first floor (don’t ask) 3m x 6m conservatory. It’s brick/breeze block up to the timber windows which are double glazed in a timber structure up to the timber rafters. It’s got a polycarbonate roof. My problem is the usual one with conservatories – being either too...

Hey everybody, ~1950's two storey hip roofed house, with part of the roof extending down through the 1st [UK] floor: The original rafters are suprisingly small (45 x 70mm), despite some of them going nearly 8m to the apex. The main hip section of the house has been insulated for a while, but...

Hi, I'm looking at buying a small house the roof of which has been re-tiled some years ago with concrete tiles but there is no felt under the tiles. It's a storey-and-a-half house so the upstairs floor is in the roof space/rafters, and I want to insulate this roof space to use as bedroom space...

Hi, New member with an odd query. I am having to do my own loft insulation in my apartment building on the top floor. (*I have permission from building owner). The professionals won't do it because they cannot install a hatch in between the joists (too small), and the only access point is...

Hi, I have an existing garden office thats raised from the ground. It's reasonably well insulated in the walls but the floor gets very cold. The rafters underneath are accessible, and I was wondering how I could insulate from below. Would I have issues if I cut some insulated panes and pushed...

Hi all, I wonder if anyone can advise. We bought a 1930s property and decided to sleeve off/bridge the airbricks that were already there to ventilate the underfloor. I heard that the cavities need ventilation too? Will bridging the airbricks afect the cavities? We are planning on installing...

Hello. I'm about to convert my garage into a habitable space (not moved in yet, but have exchanged contracts). It’s a single skin thermalite block construction, and rendered on the outside, plastered on the inside. The main issues will be solving a small patch of damp (see photo) and sorting...

Hi. Quick question: I have rigid insulation upstands around the concrete slab in my extension, and am using self-levelling compound on it before laying engineered wood. Do I trim the insulation and level over it (creating a thin cold bridge to the masonry/bifold frame) or level first and trim...

I’m in the process of boarding my loft, which includes replacing all the insulation. As I pulled up the first-laid layer that runs along the joist pathways, I’ve found a bunch of slate and rubble. It looks like someone redid the roof, let the old one just fall into the loft space, and then...

My first post on the forums after lurking for a while. I've just moved into a new house and peeked my head in the loft to find the insulation setup is different to what I've seen before. As well as just 100mm between the joists (that I'll be adding more to soon), there's a line of insulation at...

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...
