...I was worried this would leave an unventilated air pocket, so asked if he could fill around the planed pieces of wood with spray foam insulation which he did, however I'm not quite confident that all of the air pockets would have been filled, on one side where the firings are thickest I can...

Hi I'm keen to insulate a loft with unusual construction (see below). I'm hoping that can be the usual "roll out some mineral wool" to a depth of 300mm (and raise any boarding above that by at least 50mm). But am weary of condensation risks (all the more so as this is a timber frame, timber clad...

Hello all, So a topic which has cropped up numerous times but I couldn't see an answer. We have a metal shed 13' X 10' so largeish. I've tried reflective bubblewrap on the inside of the roof to try and prevent condensation but this proved to be fairly useless over the last winter. So I was...

Yes, I also had the builder trying to deliver sockets with no insulation behind them! seems to be a common theme. It made a difference to fix that. If there is enough slack in the wires you can gently pull out the backbox and then insulate behind. If the wires are a bit short that wont be...

Hi all, Ive recently bought a 1929 semi and have noticed that the entire inside of the roof is spray foamed. Unfortunatley I have a few slipped tiles now after some strong wind and missing motar on the ridge. I have been told bad things about the spray insulation but on a quick removal test...

I have one part of an original wall behind plasterboard in a converted cellar which is becoming wet due to condensation as you can see by the below picture, the wall had just been wiped so not currently wet. The rest of the wall is bone dry, probably because most of it is not tanked, but I am...

I have one part of an original wall behind plasterboard which is becoming wet due to condensation as you can see by the below picture. The rest of the wall is bone dry, probably because most of it is not tanked, but I am unable to ventilate the area sufficiently due to the layout to help stop...

The rest of the wall is bone dry, probably because most of it is not tanked, but I am unable to ventilate the area sufficiently due to the layout to help stop this condensation. As the area in question is only small, just bigger than the cut out piece, would spraying insulation foam directly...

Deleting on how complex the framework under the floor you might like to get a two part spray foam for insulating it

If it is the joist ends penetrating the party wall, you only need to take up a couple of boards running along the wall. Clean it up well, with a brush and vacuum, moisten with a water spray, and use a nozzle to inject expanding foam (I use the pink fire resisting grade) round the joist ends. A...

Not easy there are wall ties everywhere and the access is quite narrow, that is why I thought of using spray foam. But I would need quite a lot, so I'd need some sort of industrial machine, if there was one for hire. It is a flat roof structure tacked on the side of the house, under the gables...

I was thinking the dpc tucked up behind the bottom of the steel shed. I'm even going to spray the inside of shed in spray foam insulation, when tucking the dpc up behind it, it'll stick to the spray foam. This way if any rain trys to travel in, it can travel in and up. In theory this sounds...

Hi everyone, I have a 1930s chalet bungalow,. Cold drafty house, with issues. Expensive to heat! Insulation: 1. it has cavity injected insulation. 2. Loft insulation ordinary type 100mm under loft boards and 400mm on none boarded areas, I realise I could put pir under boarded section to...

Coincidentally, We are currently stripping a roof That has spray foam applied directly to the underside of the !F felt. Roof had also been relaid over TLX Gold laid directly on top of the 1F.. Very odd. Its a relatively small roof of 80m2 and has taken 4 guys 4 days to remove the S hite and...

Metal roof noisy when it rains? Spray foam under makes it quiet and insulates

Assuming it is condensation, then spraying some foam or inserting some insulation into the gap won't make much difference, the lintel will still be cold and where the warm air meets the lintel just above the window wont change.

We have a garden room built on top of an old half-cellar (underground one side only due to slope). The floor is a concrete slab built on a steel girder framework inside the cellar and it is sucking all the heat out - leave the heating off overnight and it's down to single figures by morning. A...

The insulation boards should have expanding foam sprayed between the gaps, then aluminium tape over the joints.

FYI Just bought the Pro IOS (£480 version) hopefully reveals some atrocities in the insulation / weakspots. Also have an air test booked for this Friday. Also hoping this will reveal some of the more leakier parts of the property with regards to air flow. Even if they dont find anything obvious...

Yeah ok maybe I need to speak to our building control folks and see if they can recommend a local team to do it. Yeah that’s what I’m hoping to do ahead of the air test by DIY’ing as much as possible. We don’t have a hatch as it has two dorma bedrooms on the top floor, has fire rated French...
