Loft Insulation: Improve Heat Retention and Energy Efficiency from the Top Down
Find out how loft insulation keeps your home warmer, lowers energy bills, and protects against damp — and why professional installation with Proofterior makes all the difference.
Why Loft Insulation Matters for UK Homes
Did you know up to 25% of a home’s heat is lost through the roof if it isn’t properly insulated? In the UK’s cold and damp climate, that means higher heating bills, colder rooms, and greater risk of condensation and mould.
Loft insulation is one of the simplest and most effective ways to keep warmth in, reduce energy costs, and create a healthier home environment.
Benefits of Loft Insulation
Improve Heat Retention
- Insulation stops warm air from escaping through the roof, keeping your home warmer for longer.
Lower Energy Bills
- A well-insulated loft can save homeowners hundreds of pounds a year on heating costs.
Reduce Condensation & Damp
- Insulating your loft helps control temperature differences that cause condensation, which in turn helps prevent damp patches and mould growth.
Increase Property Value
- Energy-efficient homes are more attractive to buyers and perform better on EPC ratings (Energy Performance Certificates).
Better Comfort All Year Round
- Loft insulation keeps heat in during winter and helps your home stay cooler during hot summer months.
