Create a warmer, more energy-efficient space with Knauf Loft Roll 44 150mm, a flexible glass mineral wool insulation for cold pitched roofs at ceiling level and suspended timber floors. Delivering a thermal conductivity of 0.044W/mK, it provides a cost-effective way to limit unwanted heat loss. Plant-based ECOSE Technology is used in its manufacture, while its non-combustible construction achieves a Euroclass A1 reaction to fire classification.
At 1140mm wide, the roll is partially perforated for greater installation flexibility and can be separated into two 570mm or three 380mm sections. Lightweight and easy to position between joists, it makes insulating larger areas straightforward and efficient.
Loft Roll 44 range has an impressive thermal conductivity of 0.044W/mK and a fire rating of Euroclass A1 to BS EN 13501-1. The rolls are highly sustainable and environmentally friendly, with Zero Ozone Depletion Potential and Zero Global Warming Potential. They offer negligible resistance water vapour passage. This Knauf Loft Roll 44 is rot proof, odourless and non-hygroscopic. It does not allow the proliferation of vermin and will not encourage the growth of mould, bacteria or fungi.
Question:
What is the weight / mass of mineral wool insulation? Interested in how much load it would apply to a suspended ceiling? A density figure would be enough as I can apply that to different thicknesses.
Answer:
The Knauf Loft Roll 44 150mm Insulation pack weighs approximately 15.15kg. However, we don't have a specific density figure provided. But given the pack's dimensions and weight, you can calculate an approximate density. Please note that this is a general estimate and actual density may vary. For a more precise figure, I recommend contacting the manufacturer directly or consulting with a professional. It's also important to ensure your suspended ceiling can support the weight of the insulation before installation.
Question:
Is this product breathable?
Answer:
The Knauf Loft Roll 44 150mm Insulation is made from glass mineral wool, which is breathable, lightweight and flexible, allowing for some degree of air circulation. It's primarily designed to provide thermal, acoustic, and fire performance in the spaces it is installed, such as pitched roofs at ceiling level and suspended timber floors.
Question:
Is this flame resistant?
Answer:
This product is A1 fire rated, meaning it is non combustible and will not contribute to the spread of flame.
Question:
Can I use this material for insulating a suspended timber floor on the ground level?
Answer:
You can do yes. But as this product is not rigid in any sense of the word, you would need to provide additional support to help keep the loft roll insulation in place I.e insulation netting, to stop it from falling through.
