Poly Bead Cavity Wall Insulation

suzyq

My property is a 1930's semi, the walls are random stone there is a cavity then brick at the other side(interior). The front exterior wall has a cavity of 95mm the side exterior wall a cavity of 45mm and the back exterior wall a cavity of 90mm. An insulation rep has just called to give me a quote for mineral fibre, when he looked around he told me that it could not be done with mineral fibre because of the random stone. I was aware of this already but knew his firm also used polybead for properties such as mine. Anyhow the chap didnt know much about poly bead so he phoned his boss explaining about the wall type etc. His boss said that yes they would be able to do it with polybead The rep having to phone his boss has just made me a little nervous as I want the job to be done professionally. I dont want any problems with patchiness in the polybead insulation once it is installed. He did reassure me this would not happen as this new type of bead bonds together once in place, and it is nothing like the old type they used to use. Is there anyone out there who installs this type of bead and can give further advice. I would hate to end up a few years down the road suffering with damp patches on my walls where the bead has not been installed properly. I did ask him to send me a copy of their guarantee as he didnt have one available

Hi,

I had the poly bead done earlier this year, I'm not 100% sure but the type of insulation that caused problems in the past was urea formaldehyde, my sister has it and suffers from damp patches. I asked loads of questions when I had my survey and was assured there would not be any problems with damp.

I doubt there will be any areas not filled because this stuff even came out in-between a central heating pipe and a hole 2mm larger than the pipe, once in place it bonds loosely together. I found some in the electric meter cabinet outside, it breaks apart if you apply any force, mind you assuming mine was installed correctly.
