How Thick Should Loft Insulation Rolls Be?

Current building regulations stipulate the need for at least 270mm of insulation thickness in a loft to meet the required U-value of less than 0.16w/m2k. For an existing building use 250mm. For added performance in an existing building or for a new build use 300mm. You should always consult insulation experts when installing and insulating any applications. They'll advise on how to install and what other building materials will be needed to complete a project.

What is the Thermal Conductivity of Acoustic Roll?

Acoustic Roll is not assigned a specific thermal conductivity as it is produced to meet the min 10kg/m3 as per building regulations. As its name would suggest, the product is purposed to perform acoustically as opposed to thermally, although there will be slight thermal benefit from installing acoustic rolls.
