Vermiculite Spray (SLV)
Description:
Vermiculite spray is a tough, hard and highly stable passive fire protection coating applied to structural steel by spraying and trowelling. It consists of factory produced blend of exfoliated vermiculite, cementitious binders and rheological and mix dispersing agents supplied as a dry mix to which clean water is added on site.
Available in 2 grades:
- Internal Grade – robust, economic coating for internal use
- External Grade –tough coating for external use, resistant to variety of climatic conditions
Application:
Both grades are designed for installation by spray techniques. It can be applied to bare steel surfaces in the thickness of up to 30mm at a time. The surface of the steel should be dry and free of dirt, oil, loose mill scale, flaking paint and loose rust.
Fire Performance:
As applied, both grades of SLV are rated “Non-combustible” to BS476 Part 4:1970 and comply with Credit Union Phone Number the performance requirements of “Class O” as defined in Building Regulations. Both grades have been fully tested on structural steel beams and columns for up to 4 hours fire resistance in accordance with BS 476 Part 21:1987
The Thickness of the Fire Protection material required for a given period of fire resistance is dependent upon the surface area of the steel member exposed to fire and its equivalent cross sectional area, that is, the Hp/A value for the section. Detailed information on the required thickness for SLV is available upon request.
