WestecTM Insulation System Specifications
| Two-inch thick insulating blankets with a protective skin of stainless steel face panels are to be provided for the interior walls and ceiling for the burn areas (precut to length - field cut at door and window openings). The doors and window shutters shall be protected with a minimum of one-inch thick burn room insulating panels (precut to fit).
The insulating blankets shall be rated for 2300 degrees F. and shall be unaffected by the application of water. The insulation blankets shall not crack or break, shall be free from asbestos, and shall not produce toxic byproducts in the course of the intended use. The two-inch thick insulation blankets shall have a maximum K value of 0.74 at 1200 degrees F and 0.48 at 800 degrees F (please note - smaller K values denote better insulating values of the system). |

The face panels shall have a ¾" maximum corrugation at 3 ½" on center to allow for lateral expansion when exposed to high temperatures. The base material, of the face panels, shall consist of type 304 stainless steel for corrosion protection and thermal performance at high temperatures. These panels shall attach to thermally protected channels with stainless steel screws. Stainless steel trims (type 304) shall protect all wall and door/shutter opening corners. All face screws exposed to fire shall be stainless steel and these screws shall not protrude through the backside of the insulating blanket (through screws are not permitted for maximum thermal protection).
The stainless steel face panels shall not be restrained from expanding at high temperatures, but rather the integral system shall be designed to accommodate the panel movements without creating any buckling or warping of the panels. All panels and trims shall be screw attached to allow for easy maintenance or inspection without disrupting the systems ability to move; welded panels are not allowed. Trims are to be designed to accommodate thermal expansion either through the use of slip connections or planned deformations.
Doors and window shutter insulation panels shall be pre treated water resistant, free from asbestos and shall not produce toxic byproducts in the course of the intended use. Insulation panels shall withstand a constant temperature of 1200 degrees F. and shall be unaffected by the application of water.
Temperature Summary
- Maximum safe training temperature for life safety is 1200 degrees F (continuous)
- Maximum service temperature for the insulation panels (doors and window shutters) is 1200 degrees F (continuous)
- Maximum service temperature of the wall and ceiling insulating system is 1850 degrees F (continuous)
- Maximum insulating blanket service temperature is 2300 degrees F (continuous)
Three temperature sensing devices/thermocouples are to be provided for the interior of each burn room. The thermocouples shall be grounded and consist of fiberglass insulated wiring with sealed stainless steel probes. Ceiling thermocouples shall protrude into the area perpendicular to the ceiling while all stainless steel encased wall thermocouples shall only run parallel to the walls for safety concerns.
