Have a mid 80's detached with suspended floors with air bricks.
Currently no carpets and gaps etc. at skirting boards, so plenty of draft opportunities.
The ground floor is split over two levels with three rooms open plan so a big area to heat.
I want to put in some insulation between the joists, and I'm leaning towards the cut to width boards, Celotex, laid on battens on the joists.....
Is this the 'best' solution in terms of thermal floor insulation?
The lower the u-value the better the insulation?
I need to 'foam seal' all around the edges too?
Any recommendations? thanks
