My garage is part of the house (under the en suite if it matters). Getting a new insulated garage door fitted soon. Before that, I want to reroute power and lighting which means pulling down the...

I wouldn't go just stuffing insulation in there. If the roof void is designed to be ventilated you risk introducing condensation and rotting the timber. If it is a warm deck or cold deck the...

Hi there, am in the building trade myself so hopefully my advice should be correct!! I'm assuming that the roof in question is a lean-to fixed to the front of the house, if so just make sure there is...

Thanks for that. The "roof" bit on the front is only a couple of foot wide if that.In really basic terms, what we're saying then is that it will be okay so long as it has some air flow and doesn't...

Just had a closer look. It is vented along the full length of the soffit but nothing at the top edge where it meets the upper floor.Don't I need a high and a low point to get the circulation it needs...

It's normally just at the soffit although the rest of the roof isn't usually totally air tight. Just make sure you don't block the vents with insulation and keep a channel all the way along the void....

Soffit vents running the full length Nothing at the top edge, although unlikely to be air tight All I can feel over there is the void between brick and block It's not a very big space. Seems a bit...

Cheapest way 100/170 wool insulation. Easiest way kingspan/celotex sheet. Leave both resting on the wall plate to allow air flow.

I trust the ceiling you removed was tested for asbestos.... If the house is pre-90s there is a good chance it was AIB (very nasty stuff with strict rules on handling and disposal)....

If you're not bothered about the appearance then just screw sheets of kingspan to the underside of the joist and leave it like that. It doesn't need to be plasterboarded because there's no living space...

Sorry, it was too late to edit my advice. I didn't read your original statement properly OP( slight hangover ). Rockwool over the joists and reboard I'm afraid. I didn't realise you had already taken...

Ceiling isn't down yet. That a a job for tomorrow. This bit is just the overhang at the front.House was built in 1995. What's up there at the moment is green backed plaster board. I can see bits of...

Just double check on the HSE website that they'd stopped using asbestos board for integral garage ceilings by 1995. There's some good advice there.

Green plasterboard is moisture resistant and it's used mainly in bathroom's so it's strange to see it in the garage. If you're pulling down the ceiling under the ensuite then you should replace it with...
