CCPI logos

Code for Construction Product Information (CCPI)

The Code for Construction Product Information (CCPI) was initiated by the Construction Product Association (CPA) as a direct response to Dame Judith Hackitt’s review of Building Regulations and Fire Safety set up in the wake of the Grenfell Tower tragedy.

The CCPI aims to provide greater confidence that any product information whether it's in a brochure, presentation, website, or social media is clear, accurate and unambiguous, and can be better relied upon by specifiers and end users, so they have the necessary facts needed when making design decisions, installing, using and/or maintaining verified products.

Our range of DriTherm® Cavity Slabs and our Rocksilk® RainScreen Slabs have received the CCPI Verification Mark.
