Replacing fibreboard on walls Ask your questions and find answers on many subjects relating to plastering and dry lining

[alexeix]

Hi,

My 1930s bungalow has had a kitchen added to the rear at some point and unfortunately, the brickwork only appears to be single skin.
The interior walls seem to be lined with some kind of fibreboard and there is damp and light mould forming.

I'm considering stripping out the fibreboard and replacing it with insulation and plasterboard.

So two questions:
1. is there a plasterboard product which incorporates an additional layer of insulation and if so what's it called?

2. Should I be concerned about the possible presence of asbestos, when removing the fibreboard?

The fibreboard is damp and needs to come out, but I also need some insulation to improve the situation.

Thanks in advance for any advice!

the board you are asking about is called thermal board,this board alone wii not meet regs for a single wall dweling,you will need to install a independent wall lining in metal or timber and put 100mm insulatoin inside it and then board over with thermal board.this will meet regs .but you will have to check the thickness of materials for this application

Hmmm...I do understand what you're saying about building regs, but this is purely a temporary measure to last until next spring, when the house will be demolished (should have mentioned that important fact). So the job is purely intended to improve the situation until then.

If there are batons already beneath the fibreboard though, I will be insulating as well.

Any comments about the possible presence of asbestos? Is this something which would normally have been used in such an extension?

tere is a plasterboard product with insulation.Ask in your local builders merchants.
I would doubt that asbestos would be associated will this system, but if you see anything suspicious proceed with caution

So I found the product which has insulation included, however, I also subsequently found that for a kitchen, a moisture resistant board is recommended.

Do you think it would be sufficient to use the insulated board and paint it with a silk-type emulsion?

Otherwise, I'm going to have to use two layers of plasterboard and the total thickness will be something like 65mm, plus the batons underneath.

Any comments?
