insulation

So, I'm looking at insulating my floors. 1980's Bungalow, suspended timber floor. Cost is a bit of an issue at the moment, and I'm wondering if there's any reason not to do the primary living areas first (Bedroom and Living room), then revisiting next year to install insulation under the floor...

Hi. Hope you are all well. Got a problem and can’t stop thinking about it, so would like to pick your brains! I’m laying tiles in bathroom which is just above ginnel. Before overboarding realised the whole thing is uninsulated so air from outside can easily make its way straight under the...

I'm hoping someone can shed some clear light on this topic. Theres lots of discussion online but seems to be very much a grey area with no clear answer. We've had approval to build a new ensuite in the master bedroom. Part of the ceiling is sloped/vaulted with no insulation. As part of the...

Hi, Keen not to cowboy this part of my build so looking for some advice. Seems impossible to find anything on school of youtube but maybe i'm using the wrong terms. Room is small, so 2.1m x 4m. Will be used as an office/gaming room. Desk and a sofa will be the heavy furniture. Floor...

Hi all, Just in the process of constructing a new pre-fabbed shed. Planning to store some tools and a few other bits in there so want to make sure it's insulated. At the moment the shed has 40mm studs. I've picked up some Thermal foil insulation (acts as a vapor barrier), and was also planning...

Hi all, Had loads of really useful help on here, special thanks to Woody on that front. Just wanted to list out everything i'm getting before putting quite an expensive order in (that I can't afford to get wrong). Plus it may help someone seeing this level of detail. I've spoke to building...

Just looking for some advice on insulation. My gut feeling is that wool would be better than rigid foam when insulating a tight space as the foam would have to be cut to size and any gaps would severely compromise its insulating properties. Is this right or am I missing something? Just wondering...

Hello I was going to put some insulation on my internal wall of my bathroom before I fix the mermaid board to the batons. I was just thinking do I need to seal the wall with PVA glue? Also do I need a plastic sheet between my wall and the insulation to stop moisture getting through? The wall is...

Hi there, We've just moved house and I'm about to sort loft insulation in the property (it's between the joists but not across - and certainly not up to the 270mm we want to aim for). A couple of questions if that's ok: 1. Any suggestions on which type of loft insulation? We are looking at...

Hi all, woke up this morning to a buzzing and crackling sound coming from one of the sockets in my bedroom when I turned it on, which also caused the lights to flicker at the same time, what is the 2nd socket inline on the 20A radial socket circuit. Stuff was not working/powering up on this...

I'd like to insulate my (concrete) garage floor. It's single skinned so I will seal the concrete (1st coat sealant, 2nd coat sealant + SBR). I will then use tanking slurry on the walls (1st coat slurry + SBR, 2nd coat just slurry). I expect a little slurry left over so I will use that to re-coat...

Hi all we have this wall in our house which seems to be covered in a polystyrene foam. Any idea why it would have been added? Seems to have been picked apart for some time and seems very easy to remove, but no signs of damp so wonder why it would have been added?! Insulation or to cover...

My living room is on ground floor. It has a suspended wooden floor over a large vented cavity (several feet deep). It gets pretty cold in winter. I want to get carpet in this room; both for comfort and to increase the warmth/insulation in the colder months. I’m aware that doing under-floor...

Hi, I need some advice on what wet UFH system to get for our renovation of a 1970s 3 bed bungalow. The house had subsidence so in the process of fixing that the floors were dug up and replaced with the following construction: hardcore base, membrane, 150mm insulation, concrete finish. We're left...

Hi, we're doing up a stone house, and have lots of vapour-related potential problems. Today's problem: we have an RSJ across a room, both ends in external stone walls, supporting the first floor joists. We're installing internal insulation (stud etc.) on all external walls, so the RSJ is a cold...

Hi Hi wanted to put some new lights up in garage so cut a hole in ceiling and fitted an access hatch thinking I could climb up there however after seeing the timber decided it probably wouldn’t be safe to climb around in there, I managed to fish my cables where i needed so that job was ok. The...

I've been upgrading my loft insulation. 1950s house. I have joists that are about 130mm deep. In between the joists, there was a thin layer of old glass fibre insulation and what looked like rockwool insulation over that. The insulation varied in depth and was ~75mm deep at best, ie at least...

Hi :) I have just bought a house in need of much renovation! One room is flat roof and I am unsure if I need to add any insulation between the rafters or if there is a layer of inuslation above the boards and the space between the rafters is for air flow. Any advice welcome :) Thanks

Hi I have a flat which seems damp, paint peels off the walls, the electric sockets corrode inside. Is the answer to hack off the plaster half way up and inject with chemical dpc? At some point I will probably need to insulate the place maybe internally. I have seen a video that seems to be...

Hi, i'm in a bit of a quandary... I need to lift the boards and insulate my loft to a better standard, I have these options but unsure which is best The joist are 100mm so not much room for thick rockwool. I can either cross lay more 100mm joist with an extra layer of 100mm rockwool then...
