Costs and savings
Loft insulation plays a crucial role in maintaining energy efficiency in homes by reducing heat loss through the roof. A detached house, for example, can save up to £380 per year* on energy bills with proper loft insulation. Heat naturally rises, and without insulation, a significant amount escapes, requiring more energy to maintain a comfortable indoor temperature. By adding insulation, homes can retain warmth during colder months and stay cooler in warmer seasons, leading to long-term energy savings and reduced carbon emissions.
Under the GBIS grant, eligible homeowners can have loft insulation installed at no cost, making it an accessible solution for improving energy efficiency. Insulating the loft is beneficial for various property types, including detached, semi-detached, and mid-terrace homes. In addition to financial savings, it contributes to a more sustainable environment by lowering overall energy consumption. Investing in loft insulation not only enhances indoor comfort but also supports efforts to reduce household carbon footprint

Material used for Loft Insulation
Earthwool® Loft Roll 44 – High-Performance Loft Insulation
Earthwool® Loft Roll 44 is a premium glass mineral wool insulation designed specifically for loft insulation. Widely used in residential and commercial buildings, it enhances thermal efficiency, reducing heat loss and maintaining a comfortable indoor environment. This lightweight, flexible, and non-combustible insulation material is ideal for pitched roofs at ceiling level and suspended timber floors. Manufactured with advanced technology, Earthwool Loft Roll 44 provides superior insulation performance while being environmentally sustainable and easy to instal
Composition and Properties
Earthwool Loft Roll 44 is composed of glass mineral wool, which is made from high-quality spun glass fibers. This non-combustible, resilient, and durable material is designed to provide excellent thermal and acoustic insulation. It is manufactured without any added dyes, binders, or harmful chemicals, making it a safe and eco-friendly choice for loft insulation.
One of the key benefits of Earthwool Loft Roll 44 is its breathable structure, which allows moisture to escape while preventing condensation buildup. This helps to reduce the risk of dampness, mould, and structural damage within the loft space. Unlike rigid insulation boards that require cutting and fitting, this flexible roll format conforms to the space, ensuring complete coverage without gaps or voids.
Key Features:
✓ Lightweight and Flexible – Easy to handle and install, with minimal effort.
✓ Moisture Resistant – Prevents condensation buildup, reducing the risk of mould.
✓ Non-Combustible – Offers superior fire safety with high-temperature resistance.
✓ Sustainable Choice – Manufactured using a high percentage of recycled glass.
✓ No Artificial Additives – Free from binders, dyes, and harmful chemicals.
Thermal Performance
Earthwool Loft Roll 44 is engineered to improve energy efficiency by reducing heat loss through the loft space. Its low thermal conductivity (0.044 W/mK) ensures effective insulation, keeping homes warmer in winter and cooler in summer. When installed correctly, it minimizes thermal bridging—areas where heat can escape—ensuring consistent indoor temperatures with reduced reliance on heating and cooling systems.
Loft insulation with Earthwool Loft Roll 44 helps homeowners save on energy bills while contributing to environmental sustainability by reducing overall carbon emissions. Unlike some insulation materials that degrade over time, Earthwool Loft Roll 44 retains its insulating properties long-term, providing continuous energy savings.
