Technical Information

The mineral wool insulation relies on entrapped air for its thermal properties.

Air is not a VOC (Volatile Organic Compound) therefore does not have a Global Warming Potential (GWP) or Ozone Depletion Potential (ODP).

Contains glass wool insulation with a thermal conductivity of 0.037W/mk.

A correction U value of 0.004W/m2k should be calculated to the proposed U value figures for a ceiling (U value for a new build residential ceiling not to exceed 0.16W/m2k).

The insulation materials featured in this range do not use, contain or produce Urea Formaldehyde, CFC’s or any of the soft CFC’s, ie HCFC’s and HFA’s.

Meets the air leakage requirements of Building Regulation Approved Documents L1A & L2A (20130 editions) ‘Conservation of fuel and power’ of <10m3/(h.m2) at a pressure differential of 50Pa under positive pressure test conditions.

Complies with BS5250 2011 the Code of Practice for control of condensation in buildings.
