ADVANTAGES

1. Lightweight and easy to manage on-site thanks to compression packaging, making transport straightforward.
2. Combi-cut products feature partial perforations for flexible placement between joists or as full-width rolls, improving installation speed.
3. Ready-cut products arrive pre-sized, streamlining on-site work.
4. Uncut products allow customization for joist spacing or full-width application, enabling faster installation.
5. Extended lengths minimise installation time and boost on-site productivity for Combi-cut, ready-cut, and uncut rolls.
6. Shorter lengths provide a budget-friendly solution in compact pack sizes, particularly for short-length Combi-cut rolls.

Application

170mm Loft Rolls provide thermal insulation for cold pitched roofs at ceiling height. Installation typically involves two layers: the first between joists and the second perpendicular to the joists.

Management, Cutting, and Storage Guidelines:

• 170mm Knauf Loft Roll 44 is straightforward to handle and install due to its light weight, and cuts easily to size.
• The 170mm 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 from ground level.
• Avoid leaving Loft Rolls exposed to the elements for extended periods.

About

Our 170mm Glass Mineral Wool insulation products contain up to 80% recycled content. By maximising recycled glass in manufacturing, we reduce demand for virgin materials.

Thermal

The 170mm insulation's energy-efficient design and thermal properties help maintain comfortable indoor temperatures year-round. When temperature differences between inside and outside are greater, heat loss accelerates in winter and heat gain in summer. Our 170mm Knauf mineral wool solutions limit heat transfer through convection, conduction, and radiation, maintaining stable indoor conditions. Proper insulation delivers substantial energy savings by reducing heating demands in winter and cooling requirements in summer.

Fire Safety

The 170mm loft insulation's fire performance provides passive fire protection. Buildings should be designed 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 overall impact and consequences.

Acoustic

Insulation's acoustic properties significantly improve the indoor environment for building occupants. Sound protection enhances quality of life in homes and creates healthy, productive spaces in offices, hospitals, schools, and other buildings. Our 170mm Knauf mineral wool insulation rolls deliver excellent sound absorption and noise reduction in new builds and retrofit projects, providing superior sound insulation and acoustic comfort.
