suspended floor

I've just started ripping the plasterboard off the walls in my spare room to begin re-insulating and noticed that directly beneath the boards there is a rather draughty ~10mm gap that leads directly down through the suspended timber floor to the cavity below (joist just visible to left of...

Hello all, Thanks for taking the time to view my forum post! I'm posting on behalf of my aunty who lives in an end-of-terrace approx 1940s built property. They and their neighbour both have this damp and it has spread over many months. Please could you advise is this rising damp and what the...

Hi, I’ve recently bought an old Victorian terraced house ( built in 1890 ). The property was recently updated 4 years ago by the previous owners, having most of the house re done such as new joist and chipboard flooring but under the suspended floor is just general rubbish clearly left by...

Has anybody used or had experience with the specific brand, "Therma-Foil"? https://www.therma-foil.co.uk/shop2/ I am considering using it as both some form of insulation and a vapor barrier. I have a suspended wooden floor, well ventilated below with air-bricks that are all clear. The company...

Hi there. I am working on a 1930’s Edwardian terrace house. Dining room floor was in bad condition, the rear 75% of the floor was heavily damaged by woodworm – I could literally tear the boards up with my bare hands and they disintegrated – and the last 25% of the floor nearest the rear...

Hi all I live in an 1880s victorian house with a suspended timber floor. The distance from the ground to the bottom of the joist is 20cm, the joists are 9cm deep, and the gap between joists is 32cm. The plan was to put down a permeable membrane and suspend Rockwool insulation between the...

Hi all, I'm looking at DIYing a suspended floor as part of a single internal garage conversion. Approximate size is 2.1mx4m so its not a huge area. Just going to be using it for a home office. I know I need to install a suspended floor to bring it level with the rest of the house but I'm...

Hi. I have just purchased a terraced house. Built circa 1890. It's in a row of 24 houses built on a relatively steep hill. The houses are built in pairs. Each pair is lower than the pair before as they step down the hill. I'm near the bottom. I'm situated so that, looking at the house, the house...

Most people when when upgrading a 1930’s house they think changing the boiler and replacing windows will keep them warmer and save costs on heating but that’s really only going to help so far people don’t realise the cold air under their feet and the pipes under their floor are likely not...

We have a 1.4 metre void under our suspended wood floor. The oversite below is always damp and on one side of the property there is signs of water that has percolated in at footing level and run to the back of the house. I have cleaned out all the builders muck and found that the damp has not...

I’ve read all the previous threads about this topic but it doesn’t resolve my query. I am going to use 100mm fibre insulation between the joists supported by mesh/netting underneath but do I need a vapour proof membrane over the top before relaying the floorboards? The floor is well vented...

Our semi was built in the 1900s with a traditional edwardian layout and modern extension at the rear. We moved our kitchen to the extension and now renovating the old kitchen. The "old kitchen" is suffering from rising damp on 3 walls (excluding the external wall) caused combination of things...

Hello all, we are re-doing the kitchen, it is in an extension off a terraced Victorian house. The kitchen size will be roughly 2.38m x 6m. I have a couple of challenges coming up, questions underlined. A. the floors of the main building are higher by 18cm than the current kitchen floor (which...

Hello I have a suspended floor that needs reparing and would be grateful for some advise The suspended floor was sagging in the corner and I removed the lamonate to expose the floor boards. See photo. The floor boards are rotted and the joist underneath. I'll need to replace them and treat the...

So underfloor ventilation is necessary for suspended floors - be they timber or concrete. Our extension happens to be concrete beam and block. Fine then, telescopic vents would be the usual solution to bring the vents up from below the beams up to the outside walls above DPC level...

Good afternoon, Im looking to insulate my suspended timber flooring (ground floor) the crawl space under the house is around 70cms, which I've been around and am happy to work under. Im planning on using king span between the joists. I can fit in crawl space all around the house expect where...

Sorry, this is a nested question.. Old suspended 1960s floor comprises: 3" void, 3" timber heights (sat on engineering bricks, levelled with cement), floorboards. Joist spacing sees 440mm approx inbetween joists. Joists are 2.5" wide. Goals: - insulate between timbers - UFH: install over tray...

Hi -- I've looked through the archive but can't find an answer to this particular question, so I apologise if it's a repeat. I've just moved into a mid-terrace Victorian house (c.1880) and I'm fixing up the suspended wood floor in the downstairs; this includes putting celotex in between the...

Here's videos of my efforts and progress so far I've almost completed the whole ground floor now just the remaining of the hallway I can't do till I remove the old stair but I have completed the entire downstairs central heating pipes all now insulated. So my next project now is building the new...
