Welcome to J B Building Products Ltd

In 1973 Jerry Forrest started working with Norbotten Steel Ltd. as Product Manager for Plannja, promoting long span deep decking and roof and wall cladding in PVF2. The first major project was Genesis Park, Birchwood, with Nicholas Grimshaw and Partners which featured a 10m single span grid using 200mm deep decking. After a short time with PMF Jerry established JB Building Products Ltd. in 1980, a consultancy concerned with all aspects of the building envelope but especially innovative roofing, cladding and decking products and systems.

In 1982 Jerry was instrumental in the formation of Architectural Profiles Ltd. (APL) and Ahsell Profile AB which supplied materials for many projects of note including the distribution centre for Grattan, Bradford. This was the biggest single phase building in Europe at the time. During his time as Managing Director of APL Jerry introduced a number of significant new products into the UK; most notably the first ever half-round cladding profile and a PVF2-based coating system which incorporates metallic pigments that change colour with the ambient light.
