Additionally, its lightweight nature makes installation easy and efficient, making it a popular option for both residential and commercial buildings

Does Kingspan Kooltherm K118 Insulated Plasterboard need an air gap?

For traditional insulation materials such as fibreglass or mineral wool, it's not necessary to leave an air gap between the insulation and plasterboard. These materials are designed to be in direct contact with the plasterboard and work by slowing down the transfer of heat through the wall or ceiling.

What is the thermal resistance of K118?

Thermal Resistance (R–value): 2.55 m2K/W.

Can you plaster over Kingspan?

Yes. You can add Kingspan insulation to existing plastered walls and you can plaster over any boards - but you should fix them securely in place.
