Trade Name: Astro Clad Ventilated Fire Barrier
Ventilated Cavity Barriers
Creates a ventilated fire barrier within external wall systems.
Tested on Timber and Masonry external wall systems.
Suitable for ventilated cavities from 15mm.
Independently fire tested to BS476: Parts 20 or ASFP TGD 19
30-120 minutes rating (dependent on substrate).
For either horizontal or vertical application.
Many external wall systems are designed with an open cavity to provide back ventilation. The cavity acts like an open chimney to allow for moisture dissipation and to create a back pressure to repel rain ingress.
However in a fire situation this chimney effect creates an open path for the hidden spread of fire both vertically and horizontally behind the external wall system.
The Astroflame range of fire rated cavity seals will maintain the ventilated cavity in normal conditions, leaving a continuous free air space, but in the event of a fire, the intumescent ventilated fire barrier will quickly expand to seal off the cavity to prevent the spread of fire.
Ventilated Fire Barriers for Cavities 15mm - 50mm
Many timber framed structures require a continuous ventilated to be maintained to dissipate moisture and prevent damp problems.
The Astroflame ventilated fire barriers have been tested in combustible timber constructions and can maintain the minimum 30 minute rating whilst allowing continuous ventilation in normal conditions.
Astro Clad – AFFRCLAD35
Astro Clad – AFFRCLAD35 was designed to meet the NHBC requirements to maintain a minimum 15mm ventilation gap in timber frame constructions.
The product has been successfully fire tested in maximum size cavities of 25mm fitted directly onto combustible breather membrane and fixed into the timber structure to provide at least 30 minutes fire rating.
It can additionally achieve greater fire ratings in non-combustible structures
Astro Clad – AFFRCLAD75
Astro Clad- AFFRCLAD75 was developed following an increasing demand for a suitable product to close off larger cavities up to 50mm in timber frame constructions.
The product has been successfully fire tested in cavities up to a maximum of 50mm within both combustible timber structures and non-combustible structures to provide up to 120 minutes fire rating.
Ventilated Fire Barriers for Cavities up to & Over 125mm
Astro Clad – AFFRCLAD5050
Astro Clad – AFFRCLAD5050 was designed to provide a large continuous open air space for cavities up to 125mm.
The product has been successfully fire tested to a maximum cavity size of 125mm fitted directly onto combustible breather membrane and fixed into the timber structure to provide at least 30 minutes fire rating.
The fire barrier can also be fitted in between phenolic insulation panels to provide an effective fire barrier.
Astro Clad – AFFRCLADPLUS+
Astro Clad-AFFRCLADPLUS+ offers an effective fire barrier for cavities over 125mm. The product has been successfully fire tested for up to 90 minutes fitted directly onto cement board.
The product not only offers a superior fire rating but also allows a continuous ventilation space of up to 44mm. This provides excellent ventilation behind the cladding whilst leaving enough free space for the installer to easily install the cladding panels after the ventilated fire barrier seal.
