Weather Defence Rigid Air Barrier
SINIAT WD is a weather resistant, highly breathable rigid air barrier (RAB) that is also non-combustible, vapour permeable and doubles as a fire-resistant board to provide a fire barrier between the façade and the interior. Providing better weather resistance than pliable alternatives it also equalises air pressure within the outer wall cavity to prevent water ingress. It requires no additional sarking due to its patented hydrophobic core and integrated liner and it can be exposed to weather for up to 12 months prior to being over-clad, offering early access for internal trades.
SINIAT WD is fire resistant, non-combustible, vapour permeable and weathertight all in one product. Eliminating the need for a breathable membrane saving time and reducing installation cost.
Air & Weather Tight
Along with the proprietary joint sealing system, SINIAT WD is extremely airtight with leakage of 0.002m3/m2/hr for compliance with the NCC 2019 air leakage requirements for class 2-9 buildings.
SINIAT WD is highly breathable at 0.49 MNs/g or 2.04 µg/N.s allowing water vapour to escape the cavity and helping to control moisture build up, unlike other non-permeable back pan methods.
Up to 1yr Exposed
SINIAT WD can be left exposured to the weather for up to 12 months before cladding is installed allowing early lock up and start of internal trades and linings as building is weather sealed.
SINIAT WD solutions offer fire resistant wall systems up to 60/60/60 which satisfy Deemed-to-Satisfy compliance for vertical & spandrel fire separation between floors and openings
SINIAT WD is weathertight with no need for additional sarking thanks to a patented hydrophobic core and glass matt liner technology. Propietary joint jape must be used on all joints, corners and openings.
SINIAT WD is manufactured by Etex Group, one of the largest supliers of construction materials globbally and it comes with a 12 year warranty when installed by a certified installer.
SINIAT WD is deemed non-combustible according to C1.9 of the BCA/NCC 2019 and can be used in any cladding or lining application where non-combustible materials are required.
