loft

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 I'm looking into flooring my loft and looking for a bit of advice on how people with a bit more knowledge think I should go with it. I did some measurements and drew up a plan of what's there already. It's an old style house, built around 1969. The dark grey part is the hatch. The...

Can anyone recommend on what to do with this? We have lived in the house for almost 2 years now (newly built 2020) Never had reason to go in the loft at all as we cannot use it as storage, but went up this morning and found that one of the blocks on the gable end has half of it missing, not...

I've just popped into the loft to get something out, and found little black dots covering pretty much the entire space. They're not evenly distributed, and are relatively new (last couple of months - we had a hot water cylinder installed at that time, and they 100% weren't there then). They're...

I have an existing stud wall as part of a historic loft conversion. The plan is to move it back to increase the room space, insulate and turn it into cupboards rather than loft space. As far as I can tell this wouldn’t require planning or building control. Is this the case?

A few years ago, I fully refurbished my house. During that time, whilst ceilings were down, the builder replaced the joists in the attic in preparation for a future loft conversion. Plumbing and electrics were also brought up and a staircase was also fitted. All of the above was done to meet...

Our internal soil stacks are attached to external vents on our roof and the felt has not been sealed around the pipes. The wind howls through the attic space as there’s plenty of ventilation at the soffits and along the ridge line. See attached photos. Is this a standard / best practice type of...

Hello, hoping someone can help please. I saw on another forum (old thread therefore not getting a response) about the following regarding floor joists in a loft conversion - “I gain 4 inches of head height by using the existing 4 inch floor joists (instead of new 8 inch joists as is the normal...

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...

Appreciate this has been discuss before, but looking to see if there is any updated advice. I bought a 1970’s built 3 bed. Before moving in we had some skimming done and I went to install some LV down lights. When I went in to the loft, under the fibreglass there was Vermiculite. I know...

Hi all, I'm in the process of buying a property. The RICS surveyor flagged the roof as being problematic: the purlin towards the front of the house seems to have moved by a few cm and is not fully resting on the diagonal support along its length or on the metal support in the party wall. -...

Hi, I have a bungalow that uses trusses that have a 6m span which are spaced apart by 0.6m for a total length of about 12m (about 20 trusses). Each truss uses 4 webs/posts in a 'w' formation. Forgive me if this is not the correct terminology. The trusses are made from 72mm x 36mm timber. The...

Hey all. Live in a 1950 council house and trying to get ideas to start a loft conversion. The problem is the chimney is in middle of house, and also king post. I am unsure is the chimney is supporting the Perlins. It a very confusing loft with the chimney in middle with wall slitting both sides...

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...

I have come across some random plasterboard in-between a few of our loft rafters. The previous owners had a two-storey extension built 10 years ago with some new roofing that joined onto the existing roof. There is some overlap between new roof felt (beathable) and the old existing felt (the...

Given the massive rise in energy bills coming, insulation is going to lead to much bigger savings on energy bills. Yet our loft is low and so I have a rather unusual issue - I can't insulate it to 270mm. I have just a 100mm cavity between the joists in our loft and insufficient height to raise...

I'm currently re-securing the ceiling in our bedroom as it has a bulge above the bed that is disconcerting. I've managed to find the joists either side of the loft hatch but cannot for the life of me find one between them, it's a gap of almost a meter. Any ideas? Is it possible that there are...

Hi All, Probably got the wording wrong but my newish house has no beams or insulation in the loft which is weird. Is the insulation behind the ply? Do your think I could board this and walk on it? Thanks!

Hi there. I'm looking for some advice related to an issue with our loft if that's ok. Our house is around 300 years old with the original stone roof (not listed). It has two loft cavities with an exterior wall running through the centre of the house. Since moving in 3 years ago we have done...
