Underfloor insulation & insulated plasterboard for the walls
Posted: Sun Feb 02, 2025 9:42 pm
I'm starting on my plan to improve the insulation in my 1980 extension - it's 2 storey uninsulated cavity wall, 5m x 4m rooms. Also has suspended floor, so I'm going to insulate under the floor and then add insulated plasterboard to the external walls.
Having taken the laminate floor up this afternoon, I've already got a couple of questions.
1. The heating pipes run around the wall behind the skirting boards, should the insulated boards be fixed over the heating pipes right down to the floor, or leave a gap for the warmth from the pipes to come into the room?
2. The floor is 1980 chipboard, nailed down, presumably tongue & groove, 600mm wide. I know for traditional floorboards the recommended removal method is to saw through one of the t&g joints with a circular saw & then prise it up & go from there - I assume it is the same in the case of chipboard?
Thanks in advance
