Hi everyone, First-time post here.
I live in a detached house built in 2000, it has a 10cm cavity between the walls. However, in this cavity, the housebuilders used a roll of “bubble foil” https://ybsinsulation.com/brands/airtec/ <very similar to this.
the rest of the cavity is empty.
I’ve always felt that this insulation was inadequate as the house can get very cold.
I’ve had cavity insulation people out over the years (about 5 or so) and they all tend to say the same thing, you can’t put more insulation in that gap, they say if the foil was to come away from the wall it could create a void and then could harbour damp.
I’ve really struggled over the years to find out:
- if the foil is adequate and I’ve been chasing a white rabbit for the last few years
- if not, What can be done to top up the insulation if anything
The entire estate is in the same boat as me
I thought I’d try my luck here
