Updated fire tests, new pre-weathered products and improved warranties mean architects are increasingly specifying this versatile metal for their facades
Earlier this year roofing and cladding specialist VM Zinc completed BROOFt4 fire tests for its standing seam roofing.
The results showed no flame spread and no flame penetration on vented and non-vented zinc roof build-ups.
The results were included in its BBA certificate for the warm, non-vented Structural roof. The Structural roof reduces both thermal bridges and air leakage. Details for this system and others are now available at NBS Source.
Since the founding of VM Zinc in 1837, the company has strived to continually innovate. These latest results follow the 2020 launch of Pigmento Storm Grey and Pigmento Charcoal Blue, two new pre-weathered zincs for its standard range.
In addition, VM Zinc@Work partner installation companies can now offer specifiers a 50-year material warranty on VM Zinc.
