insulation

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...

I am buying a 5m x 3m shed and have a nice flat concrete slab to put it on. shed is pre fabricated and will be assembled on delivery. https://noahgardenrooms.co.uk/product/aspen/ I have requested damp proof course and 22mm t&g flooring. There is no option to insulate under the floor so am trying...

Hi all I live in an 1880s victorian house with a suspended timber floor. The distance from the ground to the bottom of the joist is 20cm, the joists are 9cm deep, and the gap between joists is 32cm. The plan was to put down a permeable membrane and suspend Rockwool insulation between the...

I think I've got myself confused between two discrete options for insulating our house, and could do with another opinion … I'm in a late 18th century terrace, 550-600mm stone walls with rubble infill and a pitched slate roof. It's a cold house, and I'm wanting to insulate it as best I can...

I'm currently in the process of insulating my garage (cold roof). I'll be using a Moll Intello vapour control membrane after the insulation and before battens and plasterboard. The boiler is currently located on the brick wall and as such can't be wrapped (sealed) with the membrane. Is it...

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...
