• Combi-cut rolls
• Ready-cut rolls
• Uncut rolls
• Short length, combi-cut rolls

ADVANTAGES

1. Lightweight and easy to move around the site thanks to compression packaging and reduced weight.
2. Combi-cut products feature partial perforations, giving you the option to use between joists or as a full-width roll, improving installation speed.
3. Ready-cut products arrive pre-sized, streamlining on-site work.
4. Uncut products provide customisation options, fitting between joists or staying as full-width rolls for faster fitting.
5. Made in extended lengths to speed up installation and reduce on-site time (applies to Combi-cut, ready-cut, and uncut rolls).
6. Available in shorter lengths for a budget-friendly option in smaller packs, particularly for short-length Combi-cut rolls.

Application

100mm Loft Rolls insulate cold pitched roofs at ceiling height. Installation typically involves two layers: the first between the joists and the second layer perpendicular to the joists.

Management, Cutting, and Storage Guidelines:

• 100mm Knauf Loft Roll 44 is straightforward to handle, thanks to its light weight and simple installation process. Cutting to size is hassle-free.
• The 100mm Loft Insulation Rolls come wrapped in recyclable polythene packs (4-LDPE), offering temporary on-site protection.
• For longer-term protection on-site, store indoors or under cover, keeping the product raised from ground level.
• Avoid leaving Loft Rolls exposed to the elements for extended periods.

About

Our 100mm Glass Mineral Wool insulation range incorporates up to 80% recycled content. By maximising recycled glass in production, we minimise the need for new raw materials.

Thermal

The 100mm insulation's energy-efficient design and thermal properties help maintain comfortable indoor temperatures year-round, keeping spaces warm in winter and cool in summer. Heat loss accelerates when there's a significant temperature difference between inside and outside. Our 100mm Knauf mineral wool insulation stops heat transfer via convection, conduction, and radiation, maintaining steady indoor temperatures. Quality insulation reduces heating demands in winter and cooling demands in summer, delivering substantial energy savings.

Fire Safety

The 100mm loft insulation's fire performance 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 doesn't fuel fire progression, reducing overall impact and risk.

Acoustic

Insulation's acoustic properties significantly improve the indoor environment for building occupants. Sound protection enhances quality of life in homes and creates healthier, more productive spaces in offices, hospitals, schools, and other buildings. Our 100mm Knauf mineral wool insulation rolls deliver strong sound absorption and noise reduction in new builds and retrofit projects, creating better sound insulation and acoustic comfort.
