Vm zinc warm roof build up.
The unique benefits of cellular glass insulation foamglas ensures that the vmzinc plus standing seam roof system is fully supported with an insulation which is able to withstand loads in excess of 1600kn m2 without compression.
Vmzinc answers every architectural demand.
Vmzinc is one of the leader of innovative solutions in zinc for building envelop.
To note specific product detailing and installation recommendations mentioned above will vary for each sperate zinc manufacturer.
Our products make installers work easier.
Warm zinc roof construction can also use timber substrates but the need to reduce cold bridging in many countries has led to the use of rigid insulation boards and composite insulation boards or sandwich panels as the direct substrate under the zinc.
Vmzinc proposes many roofing systems and materials for the zinc roof and metal roofing.
All wall cladding should be ventilated.
Because vmzinc is suitable for all roof pitches above 3 5 and for all types of shapes straight curved folded etc it offers freedom of expression for roof design.
Zinc panels are installed to the prepared deck using fixed sliding clips with plugs and screws specific for warm roofing.
A bituminous vapour barrier is recommended.
Products typically used are warmfast and thermoseam and the setting out of the fixed sliding clips is to specific manufacture guidelines.
Our material and its aspects inspire architects and make it possible to design unique buildings that respect the environment.
Above this slope it should be considered wall cladding.
With this warm roof system vmzinc plus standing seam can be installed on metdeck composite panels without ventilating the underside of the vmzinc plus.
For a pitch lower than 14º the joints must be taped between 14º 22 there must be an overlap of 200mm just steeper than 22 or unless it changes above 40º there must be an overlap of 150mm.
Installation the substrate of the metdeck composite panels on the warm side of the roof panel must be covered with a continuous aluminium foil backed bituminous self sealing vapour barrier to.
Between the zinc plus and the insulation the vmzinc breather membrane link to 8 1 vmzinc membrane is fixed with an overlap depending on the pitch.
For standing seam build ups a roof would have a slope of no more than 70º compact roof 60º.
