Hi all, looking for advice and experiences people have had.
We have some uninsulated cavity walls. Now I know that they can be filled, but the quotes I have had have been rather expensive! ~£3K, and I am looking for something I could do myself if possible.
I have seen people talking about internal thin film insulation, but the info I have seen is for solid walls. So the question: Could I apply it to the interior of my exterior cavity walls? I know I could put it on the internal walls.
This would mean I could do 1 room at a time and spread the cost a little. Also should I fill the cavity in the future, then hopefully they will work nicely together?
Thanks in advance
