    Loft Insulation Material

    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...

    Vermiculite in the loft.

    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...

    Asbestos risk in loft

    I'm on the war path with the big A in our house at the moment, trying to find as many ACM's as possible and decide whether we need them removing. The previous owners have had the loft boarded, underlayed and carpeted about 12 months before we moved in - delightful, but I'm ripping off the...

    Polystyrene tiles between rafters

    I probably already know the answer to this question but I will ask it anyway. We had all the roof tiles replaced about five years ago and afterwards I renewed the loft insulation and boarded the loft. I also fitted 2" thick polystyrene between the rafters, the polystyrene being cut into tiles...

    Insulating Loft Futureproofed for Converting

    Hi. I need to increase my loft insulation but would like to have the loft converted in a couple of years. What would be the most efficient way to do this, reducing waste if it’s converted? It’s currently boarded, which is useful, so I think I’d rather insulate at roof level. Would PIR boards...

    Loft Insulation - A Big Con?

    I have debated installing loft insulation...... My house is a 4 bed detached and i pay £100 per month for gas and electric. Joists are 70mm so putting insulation in between joists is futile and impossible as thinnest width i can find is 100mm. And i am not stupid enough to start raising...

    Loft condensation and insulation - help please!

    Hi I'd be really grateful for help/advice - I'm panicking a bit! As a bit of background.... I am looking to replace the current loft insulation (fibreglass/rockwool), laid on the loft floor. This has been prompted by a potential problem of condensation on internal walls/ceilings; in our second...

    Downlighters Loft Insulation

    Hi, I'm topping up existing loft insulation. We have 12 downlighters. The loft insulation has been cut back around them, presumably to allow heat to disperse. I don't think that it would be practical to do the same with the top up insulation. Do I need to use those downlight protectors or is...

    Loft flooring

    Hi all I’m looking to board my loft for additional storage purposes only. Currently there are chipboard panels on top of the joists, with loose insulation just rolled out on top of this. Im not sure if there is much insulation between the joists as these boards are difficult to remove. Any...

    Hi there I have an old detached bungalow and want to put a music room in the loft as well as use for storage. The gap between the felt and edge of the trusses is 75mm, can I put kingspan or polystyrene in between the joists to insulate the roof then plasterboard. If so what is the max thickness...

    Cold garage conversion

    Just moved in to a 1950 build house and was hoping someone could give some advice. I’m a long time reader of the forum but this is my first post! I’ve started working on a room in the house which I believe used to be the garage - which has been converted into a room attached to the house at...

    Loft insulation - Cellulose or Asbestos?

    Hi There. DIY amateur here but hoping for some help/guidance. I was up in the loft in the house we just bought and noticed the insulation was a mix of the odd roll of fibreglass/wool but also this grey stuff. I was originally posting elsewhere to understand what the small nests were (since...

    How long for loft insulation to fluff up?

    Slightly random question! I'm adding 200mm loft insulation, Knauf 200mm Super Top Up Loft Roll Insulation https://www.wickes.co.uk/Knauf-200mm-Super-Top-Up-Loft-Roll-Insulation---5-61m2/p/109451 Obviously it's not 200mmm on the roll, but how long should I expect to wait for it to expand once...

    How to insulate this weird space in loft?

    Hi all, We have a couple of cold bedrooms, the top half a metre of the walls have only plasterboard and lath and plaster between them and our cold loft. I can't work out how to insulate this section. Access is poor, lines are not straight, roof structure complicates things, diagram attached...

    Insulating internal wall which is currently open to the cold loft

    Hi all, We've a couple of rooms that are always cold. Having a lath and plaster wall which is internally open to the cold loft probably doesn't help! What is best to fill this space with? Can I seal up the top with expanding foam? Do I need to be concerned about condensation? The first photo...

    Loft Insulation

    Hi, I am hoping for some advice. My builder has completed a loft and the building inspector has said the insulation is not sufficient as it has a u value of 0.22 and not 0.18. I have spoken to my builder and he says we could argue on the basis of height that additional insulation would not be...

I have a sloping ceiling in the bedrooms outer walls because the room sort of gos into the loft space. So when I am laying insulation I am careful not to push it too close to the edge...

    Is my, inaccessible, loft insulated or not?

    The house is a new build of around 4 years old. There is a bedroom above the garage. This bedroom typically remains 5-10 degrees colder than the rest of the house. The loft above that bedroom is inaccessible. I have suspected that that part of the loft is not insulated but had no way of getting...
