It offers excellent energy-saving properties and thermal performance while providing passive fire protection as a non-combustible mineral wool.
Available in three widths to suit most joist centres and in 50mm Multipack, 50mm 100mm and 135mm thick combi-cut rolls.
How many rolls?
Measure the ceiling you are insulating.
Enter the room's length and width to see how many you need.
The 5% waste allowance is our suggestion, not Knauf's: it covers trimming around the trusses. Our quote for Knauf is per roll.
