insulation

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...

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...

Hi there, Any help here would be appreciated. I have recently bought a converted stable, in my living room I have cupboards and a seat against a solid wall (see below). I want to insulate the wall behind the cupboard. The wall behind the cupboards is very damp and makes keeping the...

Hi I have a top floor bedroom where where at the external corner of the house there is a cold spot and where mould keeps forming. See the thermal image here. How are cavities formed around corners? Any ideas of the next step ? I don't think I can get a camera down the wall cavity that has the...

Hi All, new here so please bear with me. I have recently replaced the flat roof on my brick built shed and am thinking I am wanting to insulate the roof as I am getting condensation on the underside of the roof boards. I have some left over loft insulation, enough to do the job, so was thinking...

Hi I’m hoping to improve the loft insulation of a cold roof of a large wood clad, timber frame bungalow that is currently poorly insulated and struggles with heat retention. It is currently largely single glazed (I’m working on secondary glazing with Magnetglaze Extreme Pro and 4-6mm Perspex)...

I want to insulate my log cabin as economically as possible and would like to keep it warm as much as possible for 6 to 8 hours between 15 to 20 degrees. My log cabin is 4mX4m and the tallest point is 260cm ( 2.6m). So I guess the side walls are 2.4m. it doesn't have studs except on the roof...

Gah, I’m in a pickle. I’m having internal walls and ceilings/flat roof insulated as part of my journey towards getting an ASHP/more energy efficient house. Most of the walls are 1960s build cavity walls, assumed insulated on the EPC. I’ve had an energy consultant and various builders quote...

Hi all. We suffer from a lot of noise in our top floor bedroom. The walls are slopey - directly below the roof. The insulation there looks minimal to me. There appears to be enough space to add further insulation without losing the 50mm gap needed for air circulation. Can I just slide in more...

Hi all, I've just bricked up a old window in single skin outhouse and want to put in 100mm kingspan, board and skim the inside. Could you tell me how long i have to wait before getting cracking with kingspan and plasterboard? As its single skin i thought i could get started quite quickly as it...

Hi all, I'm in the process of planning an upgrade to my loft insulation. I already have rockwool inbetween the joists in the ceiling/loft floor and I'm planning on adding another 250mm at 90 degrees, following guidence, and avoiding the loft ventilation areas. However I use this attic space to...

Hi all End of terrace built in 1890. Since topping up my insulation, I have a significant build up of condensation on the breather membrane in my loft that I’m trying to fix through: - installing lap vents in between every rafter at the lowest point close to the eaves. - installing a...

I've recently had new double glazed uPVC windows installed, and since the old sash and case windows were so rotten they stripped out the whole frame with the rest of the windows. The old lime plaster on this wall basically fell off on its own after decades of damp/neglect by the previous...

Good afternoon all, as part of a major refurbishment of my dad's 90 m2 semi-detached bungalow I am considering ripping out the existing suspended wooden floors throughout (some of which will have needed re-packing anyway), adding insulation, UFH pipework, and screed. It seems simple enough as...

Hi all 1890s terraced house, laid some new insulation in the front half of the house last year, didn’t get round to doing the back half. Just been up there to find loads of condensation at the front pictures attached, non at the back. What do I need to do fix please? Bathroom is at the back and...

Hi all, just wondering what people’s thoughts are on cavity wall insulation on a 1910’s built house constructed with lime mortar. I’ve read a couple of horror stories online about people installing modern cavity wall insulation into a period property which subsequently caused a multitude of damp...

I have a situation where 100mm insulation has been put on top of an unlevel concrete slab Insulatiin boards are 400mm wide. 19mm T&G and 12mm laminate flooring to go on top. Part of the floor will be too high, and I need to reduce the height. Prefer not to have to grind concrete down. How...

Hi I've some Celotex 150mm insulation boards left from flat roof insulation project and looking to use in loft floor which has some old insulation in. Just checking that vapour barrier is still needed and that it is ok to lay as per below image, i.e. up and over the floor joists. The Celotex...

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...

I am trying to build a box to go over my poorly insulated loft hatch. This is the box so far - 4 sides and a lid. The parts are loose at this stage. But I have some questions. 1. Can you suggest a glue to use to stick the 5 parts together? 2. After gluing, can I use expanding foam to fill the...
