    Why a course of bricks under stud walls in garage conversion? (Solved)

    Thanks Tigercubrider....I am never sure how much these things isolate unless we know the exact mass & the percentage compression of the strip. On a separate note, building control have accepted the solution (tanking slurry) mentioned in my earlier post instead of the bricks under all stud...

    Why a course of bricks under stud walls in garage conversion? (Solved)

    Thanks Tigercubrider for your tips & pointers. Our rough plan is quite similar, except that our walls are inside out so two layers of staggered plasterboard, vapour layer & some insulation will be on the outside. The stud walls will be built on the floor & then erected into position. Then the...

    Thanks Leofric! I should have mentioned we have the insulation, ventilation, inner stud walls, floor & ceiling etc all worked out & agreed by building regs. Its just that we were thinking just raising the flat roof but are now considering dual pitch roof.
