This category includes high-performance solutions from EcoTherm and Kingspan, offering options for partial fill cavities, full fill cavities, internal wall insulation and external wall insulation systems.
For masonry cavity walls, products such as EcoTherm Eco-Cavity, EcoTherm Eco-Cavity Full Fill, Kingspan Thermawall TW50, and Kingspan Kooltherm K108 Cavity Board deliver excellent thermal performance while helping to control moisture penetration. Partial fill boards maintain a residual cavity that acts as a barrier to external moisture, while full fill solutions maximise insulation within the cavity to achieve lower U-values.
Internal wall insulation solutions like EcoTherm Eco-Liner and Kingspan Kooltherm K118 Insulated Plasterboard combine insulation and plasterboard in one board, allowing walls to be insulated and finished in a single installation. These systems are ideal for drylining applications and upgrading existing properties.
For external insulation, Kingspan K5 External Wall Board provides a premium performance solution designed for use behind render systems, enabling properties to be insulated externally without disrupting occupants.
Manufactured using high-performance PIR or phenolic insulation cores, many of these boards achieve thermal conductivities as low as 0.019–0.022 W/mK, helping to deliver strong thermal performance with thinner constructions.
