Ceiling Insulation Coventry
For flat roofs and garages
Ceiling insulation is essential for rooms directly below a flat roof or above an unheated garage. Without it, these areas lose significant heat. We fit rigid PIR board or mineral wool between ceiling joists to dramatically improve thermal performance and comfort.
We provide ceiling insulation services across Coventry, Nuneaton, Leamington Spa, Kenilworth, Warwickshire, Redditch, Rugby and the West Midlands. From garage conversions in Nuneaton to flat-roof extensions in Leamington Spa, we ensure your ceilings are properly insulated.
How We Carry Out This Service
- 1
We inspect the ceiling structure and identify the most effective insulation method.
- 2
For flat roofs: rigid PIR insulation board is fixed directly to the ceiling joists from below, or installed above the weatherproof layer.
- 3
For garages: mineral wool batts are friction-fit between ceiling joists.
- 4
All gaps and joints are sealed to prevent cold air infiltration.
- 5
The ceiling is finished with plasterboard and skimmed ready for decoration.
