What is Kingspan Kooltherm K118 50mm insulated plasterboard?

Kingspan K118 60mm Insulated Plasterboard is a thin product which is ideal for retaining internal space in buildings while insulating. It has a fibre-free core and is environmentally friendly – the material is non-deleterious while offering lower lambda values which improves heat retention and reduces your building’s carbon footprint.

As it incorporates both insulation and plasterboard, time is saved as you can insulate and dryline in one simple application. They also provide effective vapour control due to a composite foil reverse facing.
