SFS, the global leaders in building envelope systems has launched
its new generation NVF2F vertical cladding support system.
Created by NVELOPE, part of the SFS business, the system enables
floor-to-floor span rainscreen façades to be installed quicker than ever before
with fewer components and a stronger end-result.
The heavy-duty aluminium bracket and rail system has been
re-engineered to offer increased strength for vertical rainscreen cladding that
is designed to span floor-to-floor. The result is a back-frame system which has
one of the highest strength to weight ratio for conventional vertical
rainscreen support systems that fixes directly into the concrete floor slabs.
This makes the NVF2F ideal for multi-storey buildings, including car parks,
residential apartment blocks and commercial developments.
NVF2F provides a solution for projects that have limited fixing
locations. Capable of spanning much larger distances compared to conventional
framing systems, the system is perfectly suited to span full floor levels,
supported by brackets fixed directly into the concrete slab at each level.
David Fraser, Business Unit Manager at NVELOPE, said: “Our new
generation NVF2F represents a step change in rainscreen attachment for
multi-storey buildings. It offers the low weight and handling benefits of
aluminium whilst engineering the metal in a way that offers great structural
strength. The result is an innovative engineered system which is easy to
handle, very quick to install and completely aligned with sustainable building
design.
“With our unique Project Builder service, we can provide detailed
guidance on the configuration needed for brackets and rails bespoke to every
application. This takes into account all load calculations and the building
design to set out the most robust, reliable cladding support solution.”
NVF2F is available in four different bracket sizes – 72mm, 122mm,
172mm and 222mm – which include a 5mm clip-on thermal isolator as required.
Each bracket has two primary fixing holes, one used per bracket, but with a
second hole allowing for different positions to be used instead, such as in
cases where the primary slot is not accessible.
Brackets are fixed directly to the concrete floor slab
edge. The SFS MULTI-MONTI® concrete fixing, which provides
a secure anchorage in concrete without the need for wall plugs, is the
preferred fastener to deliver a secure, lasting installation.
Two rail profiles are available – aluminium box and T box. These
work in the same way as NVELOPE L and T profiles.
Once rails are fixed in position, the cladding panels can be
installed. For additional fire safety, a mineral wool ‘fire plug’ is installed
into the rail profile to prevent a chimney effect in the event of fire.
