High Thermal Performance

Thermal conductivity of 0.044 W/mK significantly reduces heat loss through the roof.

Knauf ECOSE Technology glass mineral wool

Revolutionary ECOSE® Technology

Knauf’s unique ECOSE® Technology sets a new standard in mineral wool insulation. Manufactured using a bio-based binder derived from rapidly renewable materials, it contains no added formaldehyde or artificial colours.

For installers and DIYers, this means the insulation is noticeably softer to the touch, produces significantly less dust, and is completely odourless. It contributes to superior indoor air quality and is backed by the Eurofins Gold Certificate for Indoor Air Comfort.

Installing Knauf Loft Roll 44 between 400mm joists

Effortless "Combi-Cut" Installation

Time is money on site, and tight loft spaces can make cutting insulation difficult. Loft Roll 44 features a smart "combi-cut" design—it arrives partially perforated.

With a simple tear, you can split the 1140mm wide roll into either two 570mm rolls or three 380mm rolls. This allows for a perfect, friction-fitted snug install between standard 400mm or 600mm timber joists without the need for extensive measuring or cutting tools, dramatically reducing on-site waste.

Unrivalled Fire Safety & Efficiency

A poorly insulated roof can account for up to 25% of a home's heat loss. With a thermal conductivity of 0.044 W/mK, the Knauf Loft Roll 44 traps heat effectively, keeping your property warmer in the winter and cooler in the summer while lowering carbon emissions.

Furthermore, safety is paramount. This insulation holds the elite Euroclass A1 Reaction to Fire rating. As a completely non-combustible material, it will not contribute to the development or spread of a fire, providing total peace of mind for homeowners.
