Premium performance pre-formed insulated cavity closer

Kingspan Kooltherm Cavity Closer PLUS is manufactured by joining Kingspan Kooltherm Cavity Closer sections to produce a pre-formed frame, for use with masonry cavity walls in England and Wales only.

It is made to specified opening sizes, eliminating the need for temporary timber formers or on-site cutting. This reduces installation time, and helps to achieve airtightness requirements.

Our product brochures include construction details, handling advice and installation guidance.

ψ–values
