For a warm, energy-efficient home built to modern standards, the Knauf Earthwool Loft Roll 44 200mm Combi (6.84m²) (Product Code: 12715820) is a dependable trade and DIY favourite at TJ O’Mahony. Designed for insulating cold loft spaces, this high-performance mineral wool roll delivers excellent thermal results while remaining easy to handle and install.
Manufactured using Knauf’s innovative ECOSE® Technology, this insulation is soft to touch, low in dust, and odourless – making it more pleasant to work with on site. The 200mm Combi roll is designed to be laid over existing insulation to help you reach the required depth for current Building Regulations, reducing heat loss through the roof and helping cut energy bills all year round.
Ideal for both new builds and retrofit projects, it offers a practical, cost-effective solution whether you're topping up existing loft insulation or starting from scratch.

  • Key Features:
    • High Thermal Performance: Excellent thermal conductivity to help achieve required U-values in loft applications.
    • 200mm Combi Roll: Perfect for topping up existing insulation to recommended levels.
    • Generous Coverage: Covers 6.84m² per roll for efficient installation.
    Soft & Easy to Install: Flexible mineral wool that friction-fits between joists with minimal cutting.
    • ECOSE® Technology: Low dust, low odour, and made using a bio-based binder.
    • Non-Combustible: Euroclass A1 fire rating for added peace of mind.


    Technical Specifications:

    • Product Code: 12715820
    • Thickness: 200mm
    • Coverage per Roll: 6.84m²
    • Material: Mineral Wool
    • Thermal Conductivity: 0.044 W/mK

    TJ’s Tip:

    For best results, lay the insulation between and then across the joists to minimise thermal bridging and achieve the correct overall depth. Always ensure good ventilation is maintained at the eaves. Wearing gloves, long sleeves, and a dust mask will make installation more comfortable on the job.
