Boost your thermal performance and reduce heat loss with the Knauf Loft Insulation Roll Roof Lagging – a versatile solution for lagging attics and floors. This roll offers a straightforward way to enhance insulation in both traditional loft spaces and underfloor areas, contributing to a warmer, more energy-efficient home.
Designed for ease of use, this roll features a 100mm thickness option, ideal for adding a supplementary layer over existing mineral wool insulation. It’s particularly beneficial where you need a lighter touch, allowing you to top up your lagging without completely replacing it. The same trusted Knauf roll used across both loft and floor applications ensures consistent performance and ease of installation – minimising disruption and maximising efficiency.
Crafted from non-combustible glass mineral wool, combined with an ECOSE bio-based binder, this roll offers a sustainable insulation solution. The mineral wool provides excellent thermal properties while maintaining a stable structure, resisting moisture and fire hazards. Crucially, it’s important to note that the 100mm thickness alone may not fully meet current Building Regulations – consider combining it with other lagging products for comprehensive coverage.
This mid-range roll is perfect for homeowners looking for a reliable and cost-effective way to improve their property's insulation. It’s designed for straightforward installation, offering a practical upgrade to existing loft or floor spaces.
