CAFCO®BLAZE-SHIELD®
II |
| CAFCO®
BLAZE-SHIELD® II is a cement based spray-applied fire resistive
material (SFRM) designed to provide fire resistive ratings for structural
steel and concrete in commercial construction.
Applied directly to steel
beams, columns and deck, or to concrete surfaces, this product's outstanding
value and proven fire resistive performance make it an excellent choice for
concealed commercial environments.
BLAZE-SHIELD II is applied
exclusively by CAFCO licensed and trained contractors, and our technical
staff works closely with building team members to meet all your fire
protection needs. |

ACOUSTICAL PROPERTIES |
| The
unique formulation of CAFCO® BLAZE-SHIELD® II makes it
a very effective thermal insulator. This benefit is important in reducing
heat loss, particularly when applied to the underside of a roof deck, which
may allow a reduction in roof insulation. |
|
As
an efficient sound-absorbing material, BLAZE-SHIELD II adds value to the
fire protection application in areas where high-noise levels are
anticipated. Typical acoustical performance is as follows: |
