Hi all

Been think about getting our cavity walls insulated for a while and tonight
we got a knock on the door from a company that is doing this.

They gave all the spiel about government grants etc and end result is that
they will do the 3 exterior walls for 149. I'm very tempted but before I
give the final go ahead are there any pitfalls I should be aware of when
having this work done. Also has anyone had any experience of 'Insulate Your
Home Ltd' they trade as 'Ecologistics'

In case it matters we're a 1970's end of terrace 3 bed house in Surrey

Thanks

Jim
The KEY thing here is to ensure that the product is removable (ie the
operation is reversible). Forget any form of setting foam for this
reason. it can be blown in rockwool, polystyrene type pellets etc
etc
Fixed foam has a tendency to allow bridging of water
