Description

Astro Flexi-Batt is designed to prevent the passage of fire and smoke around penetrating services and is ideal for edge of slab detail and linear joints that require high movement.

Flexi-Batt permits high lateral and longitudinal movement for penetrating services, facade designs and head of wall installations. Its integral structural support system gives large aperture designs the stability of conventional built-in fire stopping methods.

Astro Flexi-Batt has a low density constructed core coated with ASTRO FLEXI COAT SEAL on both faces.

This fire batt remains flexible, with a movement capability of +/- 50% from -10 °C to +95 °C, to permit thermal and mechanical movement of services.

Causes no known effects to plastic pipes, plastic cables, sheathing or metallic components.

Ideal for slab edge applications, head of wall and movement installations.

Unaffected by oil, fungus, moisture, vermin, weather and contains no halogens or asbestos.

Installation Notes

Cut fire board slightly oversize so that the board can be compressed into the gap.

Coat substrate, services and slab edges with ASTRO FLEXI COAT SEAL.

For service penetration installations - assemble board in to the opening, ensuring a compressed fit in to the substrate aperture and around the services.

For slab edge installations - assemble board in to the opening, using ‘Z’ bracket in slab edge detail where required (If void is wider than 250mm).

Apply ASTRO FLEXI COAT SEAL to close any visible openings.

Maintain record of installation.
