Is this insulation project practical?

by ThisWreckage » Tue Aug 30, 2022 7:13 pm

I have a friend who is a keen DIYer, reasonably competent and experienced with a very practical mind. He wants to install internal thermal insulation to the two exterior walls of my ground floor flat which has filled cavity walls and uPVC double glazing. Because of the cavity wall, there is no ECO grant available for professional installation. He would design and fit it himself with my inexpert assistance, by creating a new stud wall.

Is this a project worth doing and would he be likely to do it properly? The closer I look, the more difficult and expensive it appears. My flat has a D energy rating and is 57 sq m, with neighbours above and on two sides.

At the end of the project we would replace the roller blinds with long thermal curtains, which I suspect would (at night, anyway) go a long way on their own to reducing heat loss. I live on benefits and, even though he will pay part of the cost, this seems like a big and pricey project. Advice, please!

Hi thiswreckage ,
Probably cheaper (and easier) to stick foam backed plasterboard onto the walls.
