ADVANTAGES

1. Lightweight and easy to handle on-site thanks to compression packaging, making transport straightforward.
2. Combi-cut variants feature partial perforation, giving you the choice to fit between joists or use as a full-width roll, boosting installation speed.
3. Ready-cut rolls arrive pre-sized, streamlining your on-site work.
4. Uncut rolls provide customisation options, fitting between joists or staying full-width for rapid installation.
5. Extended lengths support fast, efficient installation and reduce on-site labour (Combi-cut, ready-cut, and uncut rolls).
6. Shorter lengths offer a budget-friendly choice in smaller pack quantities, particularly for short-length Combi-cut rolls.

Application

150mm Loft Rolls provide thermal insulation for cold pitched roofs at ceiling level. Installation typically involves two layers: the first between joists, the second laid perpendicular over the joists.

Management, Cutting, and Storage Guidelines:

• 150mm Knauf Loft Roll 44 is simple to manage and install due to its light weight and straightforward handling. Cutting to size is quick and easy.
• The 150mm Loft Insulation Rolls come wrapped in recyclable polythene packs (4-LDPE) for short-term on-site protection.
• For longer-term protection, store indoors or under cover, keeping the product raised off the ground.
• Avoid leaving Loft Rolls exposed to weather conditions for extended periods.

About

Our 150mm Glass Mineral Wool insulation range contains up to 80% recycled content. By maximising recycled glass in production, we minimise demand for virgin materials.

Thermal

The 150mm insulation delivers energy-saving benefits and thermal efficiency, keeping buildings warm in winter and cool in summer. When indoor and outdoor temperatures differ significantly, buildings lose heat quickly in winter and gain it in summer. Our 150mm Knauf mineral wool insulation prevents heat transfer via convection, conduction, and radiation, maintaining stable indoor temperatures. Proper insulation reduces heating demands in cold weather and air conditioning loads in warm weather, delivering substantial energy savings.

Fire Safety

The 150mm loft insulation provides passive fire protection. Buildings must be designed and constructed to minimise fire risk, limit spread, maintain structural integrity, and enable safe evacuation. Our non-combustible mineral wool insulation acts as a fire barrier and does not fuel fire progression, reducing its overall impact and severity.

Acoustic

Insulation acoustics significantly improve the indoor environment for building occupants. Noise protection enhances quality of life in homes and creates healthy, productive spaces in offices, hospitals, schools, and commercial buildings. Our 150mm Knauf mineral wool insulation rolls deliver excellent sound absorption and noise reduction in new builds and retrofit projects, creating improved sound insulation and acoustic comfort.
