    How to raise level of loft boards?

    So I want to add insulation and then board over it - the joists are already 170mm deep so I only need another 100mm insulation. There’s not much headspace and loft legs are too long. I was thinking of running some timber around 125mm x 45mm across the existing joists which are 170mm x 45mm, so...

    Roof repair and loft insulation

    Hi, I am struggling to understand my roofing contractor's quote and reasoning behind some of the work. The roof on our rear extension (extended by previous owner) is missing the edges in the bottom corners and it slipped over the years. We need to replace the old skylights, so we want to...

    Insulating suspended timber floor ‐ do i need to do the lot?

    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...

    Rigid foam vs. wool insulation

    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...

    Internal Insulation Wall Treatment

    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...

    Single skin detached garage insulation & flooring

    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...

    Most effective insulation under carpet – above suspended vented wooden floor

    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...

    How do I stop a cold RSJ rotting my joists?

    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...
