Just pricing up my self build extension. Self build due to cost rather than want!
An approx 35m2 extension with 100mm insulation in the floor and flat roof with some insulated plaster board on the existing walls is looking like £1600 worth. The 100mm boards seem to go for £45/sheet.
Any ideas on how to get this down? Are there any bargain shops out there? Any other appropriate insulation instead of colorectal? I've seen on flea bay a few listings of "seconds" where the boards have a bit of damage for £25-30 / sheet.
