Customer Questions
Does this product have perforations down the middle to split in half?
Yes there are perforations, these are usually at 600mm intervals which is the most common for UK roofs.
Is loft roll itchy to touch or harmful to install?
Protective clothing should be worn, which includes a face mask and gloves. This is due to small particles becoming dislodged from the roll which can be inhaled and can also cause iritation to skin.
What is the difference between loft roll and acoustic roll? Which should I use?
Loft roll and acoustic roll is made from the same material, the difference is that acoustic roll is manufactured more compacted creating a roll with a higher density. This higher density helps with the acoustic performance. If sound absorption is a factor when deciding on the product to use then acoustic insulation would be the better product.
How many rolls of the 150mm are on a pallet?
There are 24 rolls of 150mm Knauf loft roll on a pallet. We are however not limited to supplying in pallet quantities.
