3 In situ testing approval CIM 122/R3 LABC is a very flexible, easy to fit, multilayer insulation that offers tremendous thermal benefits. Tests have shown that provides insulation equal to 270 mm of glass wool when installed in a pitched roof situation. now has full certification with Local Authority Building Control. How does Work? Due to the special composition of multi-layers of insulation effectively deals with all forms of energy transfer (i.e. conduction, convection and radiation). works most effectively by reflecting infra-red radiation. This means that not only is effective in winter, by reflecting heat back into the building and cold out, but also in summer Super-Quilt is a very effective solar over heating barrier reducing the need for artificial cooling systems, and preventing uncomfortable heat build up in the roof. BRE testing Moisture Performance of BRE Report number BRE was commissioned by YBS Insulation to assess the vapour transmission of. The vapour permeability was used to calculate the vapour resistance (Rv) of the material. The Rv was measured as 390.6MNs/g.
