Envelope Construction

Zinc is an excellent roofing and cladding material which will give long and almost maintenance-free service if installed properly. Proper installation means not only the correct fixing of the zinc itself but also the correct design and installation of the supporting structure.

In traditional roofing and cladding this structure provides continuous support for the zinc, whereas, in engineered facades, metal railing and point fixing systems are employed.

The building envelope is built up in a series of different layers on site. Depending on the design of the roof, it can include, from outside to inside:

elZinc Cladding
– Underlay
– Substrate
-Air layer (ventilated roofs and walls only)
– Insulation
-Battens or metal rails and wall brackets
– Vapor control layer / vapor barrier
– Principal load-bearing structure
