It has a 12.5mm plasterboard bonded to its front surface and a composite foil based facing on its reverse surface. This insulated plasterboard has a dry lining, coated by a strong adhesive bond for protection. It is suitable for mechanically fixed or plaster dab/adhesive bonded dry-lining. Certifications: Kingspan KoolthermÆ K118 Insulated Plasterboard is manufactured to the highest standards under a management system certified to ISO 9001: 2008 (Quality Management Systems.

The Facings: The front facing of Kingspan KoolthermÆ K118 Insulated Plasterboard is a tapered edge gypsum based plasterboard which readily accepts dryñjointing materials and plaster skim.

This reflective, low emissivity surface improves the thermal resistance of any unventilated cavity adjacent to the product.
