AIM VRB Lite

Foil faced mineral wool and intumescent fire barrier for rainscreen systems, providing an effective cavity barrier solution for 'open-state' voids within a variety of facade applications. Allows ventilation and drainage of the cavity under service conditions, whilst providing up to 60 minutes fire resistance performance.

Features and benefits:

• Tested to suit 'open-state' voids up to 300 mm wide.

• Allows an open continuous ventilated airspace of 25 mm.

• Quick to install.

• Supplied with two galvanized steel fixing brackets in 1 m lengths, and 'pigtail' screws.

• Achieves a fire resistance performance of 60 minutes integrity and 60 minutes insulation.

• Tested to ASFP TGD 19 (Fire Resistance Test for 'Open-State' Cavity Barriers used in the external envelope or fabric of buildings).

The brackets should be securely mechanically fixed to the internal wall at maximum 500 mm centres using non-combustible fixings.

VRB Lite requires the additional installation of four x 75 mm long course wound 'pigtail' screws impaled though the outer intumescent facing side of the product at 250 mm centres. The pigtail screws should protrude by a maximum of 25 mm, making contact with the rear of the rainscreen cladding, to ensure that an open continuous ventilated airspace is maintained. Consult manufacturer's literature for further installation information.
