Medium Density
Isolatek® Type HP

ISOLATEK® Type HP HP is a medium density Dry Mix Spray-Applied Fire Resistive Material (SFRM) designed to provide superior fire protection for structural steel where limited physical abuse or traffic may be anticipated.

It is an inorganic, environmentally friendly, Portland-cement-based formulation that provides superior fire resistance for structural steel and concrete in commercial construction environments.

This is the product of choice particularly when exposure to severe weather conditions during the construction phase is necessary, or when application efficiency along with excellent thermal and acoustical insulation properties are desired.

ISOLATEK Type HP is the only medium density product that is classified as “investigated for exterior use” by Underwriters Laboratories, thus allowing it to remain exposed to extreme weather conditions during the construction process.

Benefits

  • Part of the most widely specified Dry Spray family throughout the world for over forty years.
  • Meets or exceeds all major fire protection specifications for Commercial structures including ANSI/ UL 263, ASTM E119, and CAN/ ULC-S101.
  • Provides up to 4 hour fire resistance ratings.
  • Exceptionally high recycled content (56% pre-consumer) and other environmentally friendly characteristics provide significant LEED credits.
  • Inorganic material formulation does not promote mold or fungal growth.
  • Portland cement-based formulation makes it suitable to remain exposed to a variety of extreme weather environments during construction, providing exceptional flexibility to sequencing and scheduling of projects.
  • Low pressure, pneumatic spray application equipment requires less manpower to operate.
  • High thermal and acoustical properties provide thermal insulation and acoustical control capabilities.
  • Worldwide manufacturing facilities ensure timely product availability.



Product Uses

Applied directly to decking, steel beams, columns or concrete surfaces for concealed commercial environments which may be exposed for prolonged periods of time during the construction cycle.

Ideal for use in mechanical rooms, parking garages, elevator shafts, pool areas, and any other area where increased durability is required.

Fire Tests & Approvals

In order to meet the performance and durability criteria set forth by the American Institute of Architects (AIA) and other major industry specifying organizations, ISOLATEK® Type HP has undergone the most rigorous testing in accordance with the world’s most demanding safety protocols.

UL 263, ASTM E119 - UL-263

Cellulosic – ANSI/UL263 (ASTM E119) – Fire Tests of Building Construction and Materials

This cellulosic fire test is traditionally used to evaluate materials for use in the protection of modern day commercial structures. This test reaches 537°C (1000°F) after 5 minutes and gradually reaches a temperature of 1093°C (2000°F) after a period of up to 4 hours.

ISOLATEK Type HP is classified by Underwriters Laboratories for up to 4 hours protection in accordance with the cellulosic fire test and is listed within various UL Designs.

UL Classification Mark

The UL Classification Mark indicates compliance with global requirements as it relates to a specific risk or casualty. With the Classification service, UL determines that a manufacturer has demonstrated the ability to produce a product complying with UL’s requirements with respect to one or more of the following:

  • Specific risk, e.g., casualty, fire, etc.
  • Performance under specific conditions
  • Compliance with regulatory codes
  • Compliance with specific standards such as international standards
  • Other condition, as determined by UL

All of the products carrying a UL Classification Mark are covered by UL’s Follow-Up Services program to verify that products carrying the UL Classification Mark continue to be manufactured in compliance with UL’s safety requirements.
