Customer Questions
Is Earthwool loft roll fire retardant?
Earthwool loft roll is a non-combustible insulation with the best possible Euroclass A1 reaction to fire classification.
Should loft insulation be fitted between the joists or be placed over the joists?
The most effective way to insulate your loft is to have a layer of insulation that sits snugly in the spaces between the joists (either a roll product or loose lay) followed by a top layer crossways across the joists. The total depth of the insulation should be at least 270 – 300 mm for the best results and to meet current building regulations.
What size roll does the 200mm loft roll come in?
The Knauf Loft Roll in 200mm comes in a roll 1140mm wide by 6m in length. The total coverage of the roll is 6.84m2.
What u-value does the 200mm roll provide?
The 200mm Knauf loft roll has a thermal conductivity of 0.044 W/mK and a R-value of 4.5 M2K/W. The calculation uses these figures along with other factors to get the U-value. The manufacturer offers a service to calculate the U-value for specific situations.
Is this the combi-cut product?
The Knauf loft roll is supplied as combi-cut. They have the advantage of being partially perforated, providing flexibility to be used between joists or used uncut as a full-width roll.
