Serving Swansea, Cardiff, Neath, Carmarthenshire, Bristol, Bath, and surrounding areas
Why Loft Insulation Matters
Heat rises—and without proper insulation, up to 25% of your home's heat escapes straight through the roof. That's money literally going through the ceiling.
Loft insulation is one of the simplest and most effective energy efficiency measures. We install mineral wool insulation to a depth of 300mm, meeting current building regulations and maximising heat retention. Our TrustMark certified teams work across Wales and South West England.
What's Included:
- Full loft survey and assessment
- Clearance of existing insulation if needed
- Installation of 300mm mineral wool
- Loft hatch insulation
- Pipe lagging where required
- Ventilation maintained to prevent condensation
- Full clean-up and waste removal
