    Loft insulation - over joists or cut-to-fit?

    Hi, New member with an odd query. I am having to do my own loft insulation in my apartment building on the top floor. (*I have permission from building owner). The professionals won't do it because they cannot install a hatch in between the joists (too small), and the only access point is...

    Am I just being lazy here? Boarding over old wall?

    I decided to put a new carpet and a lick of paint in the loft room. A couple of hours' work. Two days later... The problem was the old ceiling was sagging, and only insulated at the top. Truth is, I was concerned that there may have been no air gap at all, and mold was starting to grow on...

    Loft room - no build regs

    Hi all, I am in the middle of purchasing a 3 bedroom property, plus a loft room (note this is NOT advertised as an extra bedroom). The property is advertised as a 3 bedroom, and the mortgage valuation is based on a 3 bedroom. There is no planning or building regs for the loft room, and it has...

    Loft hatch

    Hi Currently have a loft hatch that is just a lid that you push up and move out of the way which you have to do off some step ladders. I'm wanting to change this to a pull down hatch with ladders if possible to make access easier. The house is 1930's so not sure if my existing loft size is going...

    Rubble under loft insulation

    I’m in the process of boarding my loft, which includes replacing all the insulation. As I pulled up the first-laid layer that runs along the joist pathways, I’ve found a bunch of slate and rubble. It looks like someone redid the roof, let the old one just fall into the loft space, and then...

    Loft insulation between rafters and tiles... is that normal?

    My first post on the forums after lurking for a while. I've just moved into a new house and peeked my head in the loft to find the insulation setup is different to what I've seen before. As well as just 100mm between the joists (that I'll be adding more to soon), there's a line of insulation at...

    Strengthening loft joists

    Hello, apologies if this question is asked a lot, but I find mixed answers in my searches. I want to board the loft of my 1870-ish mid-terrace house for storage, not a living space, but I also don't want to worry about the weight of the things I'm storing so might want to strengthen my joists...

    Is this a water vapor/condensation risk? Dwarf wall void in loft.

    Hi, I have been slowly upgrading a converted loft in my victorian semi. A couple of years ago I replaced the insulation in the rafters with PIR board. 100mm in between the rafters, 25mm underneath the rafter. 50mm gap between insulation in the rafters and batten for ventilation. At the...

    Air flow in loft

    Hello, I'm doing up my loft as in the drawing below. I will be using superquilt on the underside of the rafters down to the wall plate. I will board up a section in the middle with a raised floor. I already have a lot of mineral wool insulation up there which and rather than take it all out want...

    White Mould within Loft Space

    Noticed some white mould within my loft space and was wondering a few things: 1. Is this due to lack of ventilation, condensation, or both? 2. Within the pictures attached you can see felt only. I believe this is due to a window being removed (as there seems to be an old single pane window in...

    Advice needed on roof structure

    We're in the process of buying a mid-terrace Victorian/Edwardian (estimated at 1900) house and have just received our Home Buyer's Survey. Unsurprisingly, given the age of the property, it gives the impression the place is about to fall down! Most of the issues are things you'd expect of a...

    Dormer cheek and wall insulation

    Hi, in the middle of doing a loft conversion and had a question about the positioning of the kingspan in the dormer cheeks and main dormer wall. The dormer cheeks are constructed with 4x2s and the main dormer wall is 6x2. Both finished with plywood and breathable membrane with clay tiles plus...

    Improving insulation of an already boarded loft

    Moved into my house in past year(60s build) and found that the loft is boarded with insulation (blanket insulation under the boards). I have been thinking that I would like to further insulate the loft and don't really need the boarded area at present. One option would be to pull up all the...

    Hello All. I need advice regarding my loft, specifically insulation under and around the cold water tank. There is a bit of a story to explain everything that has been going on with my loft leading up to this and for that I apologise in advance if it is a bit long winded. Early last year it...

    Hi There, Most likely in topic I have used wrong terminology to describe my issue but hopefully picture attached will do better. I am trying to make more space in my loft and install some doors to cover clutter located in deeper corners of my loft and I wonder if those "binders" pointed in...

    Loft dripping

    Hi, I've got really bad condensation Al over my loft on the timber and felt. I've noticed there's some type of silver insulation stuffed in to the eaves, looks a bit like silver bubble wrap.. Won't this be blocking the soffit ventilation? Here's a video: Appreciate any advice, hoping to...

    Want to insulate under rafters with Multifoil - no membrane under tiles...

    Hi all, I have recently bought a house (1920s/30s) and want to insulate my loft. Currently there is about 100mm of fiberglass between the joists and floored with chipboard. I really need the loft for storage so rather than add extra glass wool I want to use multifoil under the rafters - it looks...

    Is our roof safe

    We have been living in our house 16 odd years and of late have noticed that we have small walls in the loft that hold up wooden beams that act as some sort of roof support. I think they're called purlins from reading online. Our house is semi detached and there is a single purlin on the left...

    Loft Boarding

    Hi All, I'm planning to board the loft of my new build house. Initially I had planned on using the loft legs and loft boarding panels that interconnect, however, the loft legs feel flimsy. I would like to run CLS timber the opposite direction to the current joints and fix the boarding panels...
