Considering adding 200mm of Earthwool to the existing 100mm insulation in our attic,the House is a 4 bed semi 15 years old,the attic space roughly 60msq.
Roughly how soon should that pay for itself if it cost €440 to put in (incl covers for down lighters and flooring round attic door)
Average heating costs and gas boiler.
Thanks.
