0.7mm thick Rheinzink Blue/ Grey standing seam roofing, with a Rheinzink ventilated ridge detail, all fitted on a vented substrate with a structural Vapozinc underlay.
Additional stainless steel fixed and expansion clips we’re fitted and spaced at narrow centres to ensure the additional PV panel weights did not interfere
with the roof natural expansion / contraction. Rheinzink box gutters with underslung galvanised brackets were also used, along with
expansion joints installed every 6m. 100mm zinc downpipes also installed.
