Astro Clad PLUS

Astro Clad Plus offers an effective fire barrier for cavities over 50mm. 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 external wall system, whilst leaving enough free space for the installer to easily install the facade panels after the ventilated fire barrier seal.
