We offer a clear “invisible” water sealant designed for home-owners who wish to keep the natural look of their brick or stone walls.
Its a bit of pain if you already use your loft for storage.We were told it would have to be empty as they just came and laid a load of loft insulation down.
We've been offered this, but I've heard/ read that cavity wall insulation can cause damp (presumably due to it stopping air circulation?). Does anyone have any better knowledge on this.
The beads - variously branded but e.g. Springvale's EcoBead Platinum - are great, waterproof, cannot form damp bridges and do not settle/compact.
The fixtures do a pretty good job of sealing the ceiling holes.
I would have thought heat loss from the room below would be negligible compared to the saving from the other 99% of the ceiling being better insulated
I have done a bit of research on this myself and decided to not bother with cavity wall insulation for now as it seems its not an exact science and can be a bit hit and miss.I do think however that the chances are that if you have everything like you gutters, drains, DPC etc.. in order then you shouldn't have any problem
