Knauf Insulation Loft Roll Insulation – Mineral Wool
Enhance your home’s energy efficiency with Knauf Insulation Loft Roll 44, crafted from Glass Mineral Wool and designed for insulating cold lofts at ceiling level.
These mineral wool loft rolls are non-combustible, boasting the highest Euroclass A1 reaction to fire classification and are made with Knauf Insulation’s eco-friendly ECOSE® Technology.
Product Features
- Installation Flexibility: Mineral wool easily conforms to slight irregularities in substrates, which helps in maintaining effective insulation by preventing air gaps.
- Lightweight Design: Knauf Insulation Loft Roll 44 is lightweight and compression-packed for easy transport and handling at the installation site.
- Flexible Application: Suitable for both 400mm and 600mm joist centres. Knauf Insulation Loft Roll 44 is 1140mm wide, easily divisible into either two 570mm wide sections for 600mm centres or three 380mm sections for 400mm centres.
- Sustainable Materials: Manufactured using a bio-based binder, contributing to a lower environmental impact.
- Vapour Resistant: Knauf Insulation Loft Roll 44 offers negligible resistance to the passage of water vapour, promoting better indoor air quality.
- Comprehensive Performance: Knauf Insulation Loft Roll 44 offers good levels of thermal and acoustic insulation, as well as excellent fire safety.
- Safe and Sustainable: Awarded the DECLARE 'Red List Free' label, guaranteeing it is free from harmful chemicals.
Customisable Widths for Diverse Installation Needs
Knauf Insulation Loft Roll 44 Combi Cut is designed with perforations that allow for effortless division, catering to different spacing requirements of loft joists.
You will see this on the product description as ‘2 x 570mm / 3 x 380mm’
What does this mean?
Knauf Insulation Loft Roll 44 Combi Cut comes in rolls which are 1140mm wide and features pre-marked perforations. This design enables you to tailor the insulation for:
- 600mm Joist Centres: Tear along the perforation to divide the roll into two sections, each measuring 570mm in width. This size perfectly fits the commonly used 600mm spacing between joists, ensuring a snug and efficient fit.
- 400mm Joist Centres: Alternatively, you can split the roll into three equal parts, each 380mm wide, ideal for smaller 400mm joist centres.
This flexibility ensures that the insulation fits precisely, enhancing its effectiveness by eliminating gaps where heat could potentially escape.
