ACTIS products are suitable for pitched roofs, providing the complete package combining Breather Membrane, Vapour Control Layer and Insulation. All you need to add is timber!
ACTIS have created a suite of thermal details which have been certified
within the LABC Registered Construction Details scheme.
They offer a combination of specific construction details,
good practice and points to watch checklists,
together with a range of modelled psi-values using different build ups.
