Kingspan K118 K118
The rigid Kingspan K118 insulated board enhances thermal insulation and moisture control in a range of building spaces.
What is K118 insulated plasterboard?
K118 insulated plasterboard is an insulated composite panel designed for thermal insulation, vapour control, and drylining. It features an insulated phenolic core bonded to plasterboard on the front and composite foil on the back.
What is K118 insulated plasterboard used for?
You can use Kooltherm K118 in several ways:
- To insulate walls and ceilings.
- As drylining in solid masonry wall refurbishment.
- For vapour control. The foil facing on the K118 panel functions as a vapour control layer (VCL), reducing condensation buildup and preventing mould.
- For moisture management. Kingspan K118 is a closed-cell insulation material that helps prevent moisture from becoming trapped within the wall.
Benefits of K118 Kingspan
Some benefits of using the K118 Kingspan board include:
- The panel has low thermal conductivity, which helps spaces remain warm in cold weather and cool in hot weather.

- It’s a multipurpose insulation board with vapour control and drylining features.
- It increases thermal resistance, resulting in a high R-value.
- It’s versatile and suitable for multiple applications.
- It reduces both material and labour costs when used as a 3-in-1 solution for insulation, drylining, and moisture control.
