Profiled Sheet Systems

As pioneers of built of up roofing and cladding systems, the natural progression was to expand our offering to include a fully warranted high performance, versatile complete system solution – AshGrid Duotherm. The new system combines our tried and trusted AshGrid support system with high quality exterior roofing or cladding sheeting and all the required fixings and accessories.

Historically, Ash & Lacy have manufactured profiled sheet in various forms for over 25 years. We offer a standard 32/1000 profile which is produced in-house and a 19/1000 option is also available on request.

With our innovative manufacturing capabilities combined with our technical support services, we are able to offer a range of materials and material finishes, backed by technical services including u-value calculations, setting out, material take offs and fully assessed firewall constructions – supported by a 25 year system warranty.

A vast range of specification requirements can be achieved using AshGrid Duotherm systems, including aesthetics, U-Values, acoustics, fire resistance and vapour control.
