Product Information

Kingspan Kooltherm K118 Insulated Plasterboard is a premium performance, lower lambda internal wall insulation that makes the board retain more heat, with a fibre-free rigid thermoset phenolic core. 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.

Kingspan Kooltherm K118 Insulated Plasterboard is manufactured to the highest standards under a management system certified to ISO 9001: 2008, ISO 14001: 2004, BS OHSAS 18001: 2007 and ISO 50001: 2011

The front facing of Kingspan Kooltherm K118 Insulated Plasterboard is a tapered edge gypsum based plasterboard which readily accepts dry jointing materials and plaster skim.

The reverse facing of Kingspan Kooltherm K118 Insulated Plasterboard is a low emissivity composite foil, autohesively bonded to the insulation core during manufacture. This reflective, low emissivity surface improves the thermal resistance of any unventilated cavity adjacent to the product.

The core of Kingspan Kooltherm K118 Insulated Plasterboard is a premium performance fibre free rigid thermoset phenolic insulant manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

Insulated Plasterboard FAQ's

Insulated Plasterboard FAQ's

What is Insulation Plasterboard?

Insulation plasterboard is a commonly used building material, which is comprised of a sheet of standard plasterboard or gypsum board, and a sheet of insulating material sandwiched together into a single sheet. Insulation plasterboard is a great option for supporting improved insulation in your home. If you're looking to protect the environment by improving your energy consumption whilst keeping bills low, we highly recommend installing plasterboard on each wall of your home. Using thermal insulated boards will increase energy efficiency, as it reduces reliance on fuel and heating.

Where is Insulation Plasterboard Used?

The main use of insulated plasterboard is to line external walls, usually brick walls that do not provide effective insulation.  It is normally quicker to install than the traditional dry-lining/insulation method, and can be a cheaper solution to using foil-backed plasterboard and a layer of traditional insulation material. It also gives you the advantage of offering a thermal layer with a thinner profile, resulting in less room being lost overall.

Insulation Plasterboard Benefits

While insulated plasterboard isn't the most environmentally friendly option for adding insulation in your home, it does have the advantage of being a low cost method to stop heat from escaping through one wall or another in your home.
