ventilation

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...

Hi guys. New user....hope you can point me in the right direction. One of my rooms on the ground floor (of terraced house) has a bricked up fireplace but the chimney was not capped. I had that done a few years after moving in as paint work started flaking on one of the chimney's adjacent...

Hello folks, whilst getting ready to paint our upstairs box room to make it into a nursery, I unscrewed a metal grill vent, and found a small cavity packed with old newspaper. I'm fairly certain fungus-riddled newspaper isn't ideal for a baby's room but should I just clear it out completely (and...

Hi guys, Long time lurker. Remodelling a flat to convert recesses into an internal kitchen, very common in these parts. There will be no windows, just a door into the hallway. My question is this: am I allowed to have a gas hob in it? I thought it was allowed with the appropriate mechanical...

We have a Victorian terraced house, with timber joists/floor on the ground floor. We have 3 double (flood proof) airbricks to the front of the property, however, at some point in the past a large extension was built across the entire back of the house with concrete floors and we do not have any...

We have a sorted of converted loft space, which is carpeted, have plasterboard ceiling and a narrow staircase from first floor. After moved in 2 months ago, we noticed in the last 2-3 weekend that there are a lot white mould on the front ( north facing) and side of the ceiling, and it is...
