Insulating boards - 1930's Semi question

Hi everyone


I've bought a load of standard boards and now decided I may want to insulate them with polystyrene, can this be done? Literally some spray glue and bosh...

I only ask because I've already got the boards, and have a few cold spots and damp patches in the old plaster.

Upstairs I've taken the walls back to brick, repaired what needed to be repaired, and dot/dabbed them.

Downstairs I'm concerned with doing the same without insulating because of a) the damp and b) it being colder overall downstairs.

I've attached an image of one of the walls. I'm getting it on the joining wall between the properties as well as a bay window at the side of the house. It's where the moisture has turned the wallpaper paste back to, well, paste.

A damp 'specialist' came out and just wanted to flog me cream dpc and membrane, nothing about getting to the cause of the problem.

Sorry to go on about the damp a bit, as I know there's another section for that.

Thanks in advance for any help.

Rob

Spray glue Xps 5-8 cm to wall, put some some mechanical fixings, overboard it using spray glue.

This doesn’t sound good tbh

I’d send boards back and get plasterer round to have a look
Sometimes it’s best to admit you need help

Thanks for the response Vincey.

Yeah we're getting quotes to have the pro's round, the dining room to-be lounge is too big of a job for me. I ordered extra boards when getting some for upstairs (hence having them already for this room).

I''ll put out a job for pricing in the relevant section and hopefully get some traction with it.

Seems like the rain water drain at the side of the house was literally a hole in the ground, collecting water and building up in the earth around underneath the block paving. It was then making it's way under the house and breaching the slate dpc.

I'm going to confirm a few things in the damp section of the forum before taking action.

Thanks guys
