High strength
Superior Fire Resistance
KlasseSEAL Interface Sealing Membrane HD (KS007) meets the fire performance requirements for membranes installed on “relevant and higher risk” building types as defined in Approved Document B of the Building Regulations for England and Wales.
When installed over compatible substrates with a minimum Class A2-s1, d0 fire performance provides a Class B fire performance in accordance with EN 13501-1.
Breathable Seal
When correctly installed with Klasse FR Membrane Adhesive (KB025), it provides an air and fully watertight seal over the construction joint which remains breathable to enable any trapped incidental moisture or condensation to escape out through to the external side of the wall construction.
It can also be used to seal and protect horizontal and vertical linear joints between sheathing boards and the main structure.
Water resistant
When tested for water resistance in accordance with EN 1928 with a 2 kPa head of water, KlasseSEAL Interface Sealing Membrane HD (KS007) achieves the criteria for Class W1 in accordance with EN 13859-2 and also remains watertight when tested over for an extended 24 hours test duration.
FULL FACADE SOLUTION
KlasseSEAL Interface Sealing Membrane HD (KS007) should be bonded back to the frame and substrate using Klasse FR Membrane Adhesive (KB025) and can be used in combination with a compatible Klasse FR Breather Membrane to provide a full façade solution. When used together they form a continuous weather and airtight barrier around the full building envelope including structural openings.
It is important that KlasseSEAL Interface Sealing Membrane HD (KS007) is installed in the correct orientation with the smooth/coated side always facing outwards towards the external environment.
