Pitched Roof

Insulation is laid between and above the joists to a thickness of 270mm (11inches) (the current recommendation for mineral wool) and as demonstrated in the financial savings it is a very cost effective upgrade.

Flat Roofs

Flat roof insulation is typically installed when the roof is built or weatherproofed. Designs vary and are referred to as warm or cold roof constructions. This relates to whether the insulation is placed above the ceiling but below the actual roof material or above the roof material and under the waterproof covering.
