ISOLATEK® Type 300 (Worldwide)  
CAFCOR FENDOLITE® 300  (Americas)  
Industrial Spray-Applied Fireproofing  

ISOLATEK Type 300 is a durable, gypsum based, wet mix, commercial density Spray-Applied Fire Resistive Material (SFRM) designed to provide fire protection to concealed floor and roof assemblies, steel beams, columns, and joists in building construction projects.

In addition to fire resistance, ISOLATEK Type 300 also provides thermal benefits. As a thermal insulator, it is effective in reducing heat loss, particularly when applied to the underside of a roof deck. The R-value added by ISOLATEK Type 300 may also allow a reduction in roof insulation.

.ISOLATEK Type 300 is very cost effective; requiring less material to achieve required fire ratings and offers the best fire resistance performance per unit thickness in its class.


• Best fire ratings-minimal thickness

• Lightweight gypsum based material is easy to apply

• Provides additional value as a thermal insulator
