ventilation

It’s time to make the cut across the ridge of the breather membrane… cassette roof construction ie; tiles, batten, counter batten, membrane, osb, 50mm air gap, rigid insulation, osb. However it just doesn’t quite feel right after working so hard to protect the building and keep water out. I...

Hi All, A quick question which i hope has a straightforward answer. We have a cold/open/vented loft. Air comes in via the soffits below the rafers at floor level. I've insulated the floor to recommended standards and boarded, being careful to leave adequate space around the edges so...

Hi, I'm looking for advice on a fireplace we have inherited, we organised a service and the engineer said ventilation was a required, transpires this has been blocked up since 2005. We had a copy of the last gas service completed by the previous owner on which 'Ventilation' was marked as pass...

Hi, We had a new patio laid a couple of years ago. We had some concerns at the time (sandstone slabs laid on a ring bed of cement not a full bed), slabs too high v damp proof course and air bricks, slabs built right up to house walls. We've started to get a lot of woodlice in the house and are...

My neighbors kitchen extract vent is beside the flat roof of my ground floor extension and the smells can somehow be smelt inside one room of my house. I closed all windows and trickle vents but found that in one corner of the room the smell was literally coming up through the floor. I know that...

Hi, was hoping for some advice We are in a 1930s semi which has always struggled a bit with moisture and is very prone to mould forming. We are currently having a loft conversion done and it prompted me to think about solutions. Once seems to be PIV however we are obviously losing the majority...

I am converting an old outhouse into a bedroom. This is a single room building apart from a small enclosed WC within the room. It is 13’x13’ with a solid double brick wall and slate roof. There is a door entrance, an opening window in the WC and an opening skylight in the vaulted roof. 4x2 stud...

Hi all My en suite (right of picture) is completely ‘internal’ - there’s no exterior walls. It’s right in the middle of my flat, and has zero ventilation. It’s a period conversion, I’m on the ground floor and there’s 2 flats above me, so venting ‘upwards’ isn’t an option. The closest...

Dear forum members! Would you be so kind and help me understand the actual difference between the following multi-vent offerings on the UK market? They are of identical dimensions and almost identical design. But the prices are very different (£30, £120 and £220)! What's the catch? Isn't...

Moved in 2 years ago, and had condensation issues in winter, in the rooms with external walls (rooms which have the the four corners of the house). Would an air vent fix this issue, also I was thinking of a hit and miss vent in each of the rooms, but fitting an air brick would be difficult to do...

Morning all, Next problem to tackle. Old chimney was rendered years ago ( not sure when) and I had it stormdried 2 months ago but water is still tracking through the brick work and then running down the face inside the loft. 100% sure it is not a problem with the roof all soakers in place...

We have a problem with white mould on our rafters, which has been put down to poor ventilation. I am hoping for some advice on how to improve our situation ... This is a late 19th century terrace house with a London pitch or butterfly roof, which gives us two completely separate, shallow loft...

Do you think this is only a tilt window? The handle doesn’t turn to 90’. Thank you!

I know there are a lot of threads on here regarding loft condensation - I've already read many of them - but despite improving the ventilation I still encountered problems last winter. The property is a late 80s detached house. A few years back I replaced much of the original loft insulation...

Hi all, Really hoping you can help with a problem with the roof of my newly converted loft. I had a torrid time with the build (over budget, overran, had to do loads myself) but it has been generally finished and has been signed off by building control. The loft conversion is a full width flat...

Hi all, I'm looking for some opinions on the cause of some wet rafters in the attic. The rafters to the rear (north facing) elevation are all wet on top and down the sides. The rafters on the front (south facing) elevation look to be okay. I'm trying to work out if the likely cause is a roof...

Hi all, Have put this here rather than electrics as also looking for general advice on ventilation and reducing condensation, etc. Currently converting a block outbuilding into a utility room to house washer/tumble dryer/chest freezer/garden sink with only cold tap. The shed in its current...

Hi all End of terrace built in 1890. Since topping up my insulation, I have a significant build up of condensation on the breather membrane in my loft that I’m trying to fix through: - installing lap vents in between every rafter at the lowest point close to the eaves. - installing a...

Hi all We live in a semi detached Edwardian property with two large bay windows in the master bedroom and lounge. In the master, no matter what we do we seem to get excessive condensation each morning. We have tried a dehumidifier (didn’t work) so am at a bit of a loss to what we could do. We...

Hello The chimney breast and hearth have been removed on the ground floor. The chimney breast and hearth remain on the first floor, and the chimney breast goes up into the attic and onto the chimney outside. The chimney pots have been capped and have ventilation points. However there is no...
