Arlington, Texas -- Demilec USA says its Sealection 500 insulation has passed the AC 377 Appendix X test, covered by only 5 wet mils (3 dry mils) of Blazelok IB4 intumescent coating.
Meeting this test allows Sealection 500 to be installed in attics and crawlspaces at thicknesses of 7-1/4" on vertical surfaces and 11-1/4" on the horizontal surfaces, in one pass, with a coating of 5 wet mils of Blazelok IB4, Demilec says.
At 5 wet mils, a 5 gallon pail of Blazelok IB4 will cover about 1600 sq.ft. At this coverage, Demilec claims the Sealection 500 and Blazelok IB4 system is "an extremely cost competitive means of staying code compliant."
"This advance in technology shows Demilec USA's commitment to finding the most cost effective means of meeting the intent of the code" said Dave Feitl, National Sales Manager of Demilec USA, in a company statement. "Our commitment continues as our research centres develop market-changing technology for the future."
According to Demilec, Blazelok IB4 is a cost effective, high-coverage ignition barrier substitute developed by TPR2 -- a company developed to provide solutions for fire, heat, thermal and safety issues.
