Remove insulation. Vacuum Spray some water and get some expanding foam. If its a bit tight and you are worried about the expanding foam overfilling, then use low expansion foam

It had the standard spray on foam they come with, but open the airing cupboard door and the heat hits you. So added one of these Original as last picture. Not covered as neat as they show, but clearly going to retain more heat. However, as to how much it will save, that remains to be seen. So...

What type of insulation is this? It's between joists in the roof of the new build house

My home is extremely cold during the winter time, while I have floor insulation in the loft space and the dreaded spray foam at the top, the roof has no felt at all. With the design of the roof everything below the red line in the prictures is inaccessible, would it be worth lifting some tiles...

could you cut a piece of ply to go with sied of the doors internally -take an 8 x 4 sheet of 18mm or 25mm ply, then cut out an L shape so it goes up the side and across the head if you have no framing above the doors at all then, just 2 pieces plywood wood the full height of the frame both...

Moisture coming out of the drying walls and floors has to go somewhere - out of an open window would be extremely efficient

Yes, I was considering doing that, but I'm hesitant to, as the heat pump / UFH installer said it's not necessary. He also said the commissioning process takes 28 days. For a bit more context, the house is 260m2 and located in Poland, so we're planning to insulate the exterior walls, and apply...

Why are you fussing with insulation over a shed? Glue some 25mm or so, insulation to the underside of the deck to prevent localised condensation.

...and air bricks. There is no insulation in the roof, so I am considering the following options and invite comments/advice… 1. Spray foam insulation to the underside of the deck. 2. Use rigid insulation between joists with a 50mm air gap. This will need to be vented into the abutted garage...

Thank you, I’m going to have to have a good think about the best way to achieve this. It would be easier if my joists ran the other way. the other option I am considering is spray foam insulation if anyone has tried this?

Hi all I’ve built a lean to shed on the side of my garage, consisting of concrete slab with DPM and half brick dwarf wall with timber frame, plastic clad walls atop with a grp roof. After completing the ceiling became damp and mouldy so I added soffit vents and air bricks. The ceiling is...

We work for a couple of people who had the inside of there roof ( loft) sprayed with insulation foam That’s turned out to be a total disaster Will probably result in having to have there roof replaced ??

...option, but I’m concerned about its thermal performance and whether it’s the best fit for a structure like mine. Spray Foam Insulation Seems like a versatile solution with great thermal performance, but I’ve heard mixed reviews about breathability and potential long-term issues with timber...

Just had a Level 3 survey done on a property and remnants of spray foam are present in the loft space and on rafters (see pics). Surveyor has said that on lifting the insulation there was dampness present. There doesn't also appear to be adequeate ventilation in the loft space after some soffit...

Or use battens between plasterboard and VCL to form a service void. If you choose an aluminised VCL this will also provide an air gap which will enable the reflective surface to work as intended Agree with Freddy re the sheathing providing structure; if you want insulation outboard of it you...

Those pillars are a problem, you have to choose whether to bump out your insulation over them or not, which would create a cold(er) spot... probably OK in reality if building control isn't involved. You could batten or frame across them, with a frame between them. But you would lose a fair bit...

Rip felt off and spray foam will give you what you want but its controversial. If you insulate and leave a gap any moisture in the air will settle on the cold felt. That's why you need vented soffit and air gap with a flow of fresh air. If there is no air gap like with foam condensation is not...

Take the floor boards up. Put insulation between the joists. Put a vapour barrier over. Put floor boards down, re-using the boards if they can be used - if not then replace them. I don't think there's really a way of going forwards without going backwards, you can't retrofit without creating...

Garden room? As in a shed type thing? Are the walls and roof insulated? Is the floor vented? There is nothing stopping you fitting insulation between the joists. You could add a layer of insulation on top of the 20mm floor deck, but then you'd need another layer of ply to support your floor...

I've had a garden room built but no insulation was installed under the floor. It's sitting on blocks but not high enough for me to install PIR underneath. The floor is 20mm thick timber boards on 5 inch joists. Is there any type of thin insulation I could put above the floor before installing...
