15 pcf (240 kg/m3) commercial density fireproofing with excellent application characteristics. Provides fire protection for interior columns, beams, joists, decks, walls, roofs, girders, floors and pre-cast units. Tested and certified for fire resistance ratings up to 4 hours.
Southwest Type 5GP™ is a cementitious fireproofing material in the standard density group as defined by standard industry practice. Southwest Type 5GP™ is a development of the classic non-combustible vermiculite and gypsum combination first introduced as a spray-applied fireproofing by the Vermiculite Institute in 1959.
The beneficial combination of ingredients in this formulation has been continuously proven by use in demanding applications since then. Southwest Type 5GP™ is the fireproofing of choice to protect most structural elements in buildings. Application is economical because it is simple and easy to mix, apply and clean up. The installed material is strong, durable and reliable. The physical properties of Southwest Type 5GP™ meet or exceed industry standards, refer to Table 1 below.
