insulation

We've got the shell of an extension at the back of our house, completed by a builder. Roof, walls, concrete floor, etc. -- just no windows or doors. Throughout the build communication was absolutely rubbish with me constantly having to chase things up, and taking time off work for no-shows...

Hello all I hope you can help me. I do a little DIY, but I have a lot to learn. The current cold snap has made me realise how leaky my house is and I am on a mission to try and patch it up. I have noticed in our kitchen that there is lots of cold air coming in between gaps between the floor and...

Hi all I hope you're all keeping well This is my first post and I'm hoping to get some advice on a case of extreme condensation in my loft. I've read the various threads I could find, but wanted to get your take on the solutions I've been offered by several roofers before taking the plunge. I...

Hi, I've just had a steel put in to remove a pier between the kitchen and a single storey extension. I've been in the property a year and always thought the kitchen got far too cold. Turns out, its because there is no insulation in the flat roof on the extension. This was all signed off with...

Hi everyone, I'm trying to insulate the gap between the sunken gas box that depresses into the wall outside and the inside of the property. It looks like whoever did it smashed the bricks and so there is a void.... Can you advise how to do it. Thankyou The first 3 pictures are under the kitchen...

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...
