Kingspan Kooltherm K108 Cavity Board
Fibre-free rigid phenolic insulation for partial-fill masonry cavity walls. A low-conductivity phenolic core (≈0.018 W/mK) between low-emissivity composite foil facings gives high thermal performance at reduced board thickness. Part of the Kooltherm range (K107 pitched roof / K108 cavity / K112 framing) covered by one EPD.

Design & Specification Notes
Qualitative notes for early design discussion. Not product-specific EPD evidence, and not a basis for numerical comparison.
Fibre-free rigid phenolic insulation for partial-fill masonry cavity walls.
Typical Uses
- •Thermal envelope
- •Roof/wall cavities
- •Airtightness layers
Key Performance
Good thermal resistance with reduced heat loss.
Specification Actions
- •Compare embodied carbon of insulation options (natural vs synthetic).
- •Request blowing agent GWP values for foam insulation.
- •Confirm the current EPD covers the selected product, finish and manufacturing route.
Indicative Health & Indoor Air
Fibre-free rigid phenolic insulation board; low-emissivity facings. Follow standard cutting-dust precautions.
