ventilation

Hi, Before I ask anything at all, I am just going to start off with a disclaimer that I will not be undertaking any electrical work myself, I am just looking for general advice. I've lived on the top floor of a purpose built 4 storey apartment block for a few years now. Up until a couple of...

Hello, Below the floorboards, the last owner of our property (a later Victorian terraced house) had recently (2018) installed fibreglass insulation, which they have pinned up in rolls between the joists. I'm worried about some damp we have in the house, and so I pulled up a floorboard and...

Hi all, My home has an issue that during its many years of life, number of very questionable building choices have prior to my moving there The worse of which is the lack of ventilation of the space beneath the ground floor. On top of that, the back of the house has a concrete floor...

Hi all, My house dates back to about 1885. Mid terraced, redbrick, lime pointing and plastered inside with lime plaster. When carrying out some renovations I noticed a lot of blown plaster on the internal face of an external upstairs wall. I think that at some stage previous owners had used a...

I'm viewing some flats just now (built 1970) and am looking for some guidance re ventilating the bathroom in the flat I’m really keen on buying (Flat A). Sorry if this is a bit long-winded, but it’s the only way that I can describe the situation. I just need to know what my options are before I...

Hello, Shed roof insulation has been discussed on the forum before, but I'm stuck on one bit: Air Flow Please bear with me The shed is going to be a fully finished space for daily office and studio use. 5.5m x 2.5m -- fairly large Sloped roof, felted Interior is a shell - we're saving by...

Hoping for advice/opinions. I have a newly built shed with 70mm studwork which has been filled with rockwool in the walls and celotex in the roof. I plan to add soundbloc plasterboard too soon. Even without the plasterboard I am amazed about how much quieter it is already! So the Rockwool is...

Hi all, Just had our upstairs box room re-plastered - old vent taken off, so now an ugly hole into a void... it's a 1940s property - cavity wall - (filled with hay/straw?) and there is an air brick in there. The air brick appears to be blocked from the outside - can't see through it! - perhaps...

Hey all, hoping someone can help advise me on this. I rent an old terraced property that is in disrepair. When I first signed the lease it I naïvely thought I'd caught a lucky break of sorts, which obviously turned out too good to be true. I knew there were issues, but not to the extent that...

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...

Not seen a previous post on this so thought I'd ask the question -- how can I both remove and seal up trickle vents? I know what they're for but they get clogged up in the summer, only allow a small amount of air flow and they allow more sound into the house the rest of the time. We ventilate...

My downstairs "Tyneside" flat, built in 1900, often smells quite musty. The floors are suspended floorboards, no insulation but gaps filled in. There is one air brick to the front of the property and a couple at the back but when I went under the floor, they seem blocked off at the back (from...

Hi I'm new to this forum and looking for some advice. I'm currently refurbishing my house and I'm looking for advice / pros and cons of a standard fan vs something like a continuous running unit or heat exchanger. It's a 3 bed semi with 2 bathrooms upstairs and and a toilet downstairs. It's...

Just had an oil-fired boiler removed which was served by a stainless flue liner running up through a brick chimney which won't be used again. There's currently no chimney ventilation apart from the liner itself which is still open at the cowl. The liner at the bottom is actually mortared around...

Hi I will be using periscope vents to air under a block and beam floor and wondered about the below ground cavity fill. All the regs say to fill the cavity to 225mm below DPC although this will partly encase the vents in said concrete; is that okay? Also when I am at DPC the building inspector...

I've built a garden office last year and is well insulated, breathable membrane, air gap then cladding for breathable aspects. On the warm side i.e. before internal walls is vapour barrier which I research as the best for stopping moisture in winter, and effectively creating a sealed box. The...

I've just moved into a late-Victorian, mid-terrace property with a great space in the cellar that we want to use as a storage/utility area. While there is a useable drain, there is no ventilation to the space and I'd like to make sure I'm on the right track with my plans. Two surveys didn't...

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...

I'm social housing tenant and I had a survey from a company called Airtech as we have condensation on the bedroom windows. Recommendations were to change fans in bathroom and kitchen to ones with a humidistat, and install passive air vents in the 2 bedrooms. The housing emailed me with the...

Hi, I hope to install 10cm diameter round vents into the casing above our patio doors in the kitchen. My monitor tells me the space behind the plastic fascia is empty. Can anyone forsee a problem with this e.g. breaking weatherproof seals? I'm wondering about installing the vents external in...
