Fire Resistant Polyurethane Foam – Earthseal 0.5R

Introduction

This report describes the results of the test procedure that was performed on two formulations of spray foam insulation. The purpose of testing was to compare the fire performance characteristics of different crawl space insulation formulas as compared to a "calibration" test.

Three test were conducted. The first was a "calibration" (No insulation) test in which a bare floor joist/plywood and stuf/plywood systems was tested to failure to obtain the failure time. The second and third tests involved the same setup with 11.5 in thickness of Apex Foam Eearthseal 0.5R sprayed into the joist cavaties. These tests were conducted to compare failure times to the calibration deck.

The following tests are offical third party audited testing

SWRI Procedure 99-02

Test A: Calibration Test. Un-insulated Floor Joist System. No Foam:

Calibration Test Set Up

6:00 Minutes: Steady Flames Exiting The Front Of Crawl Space

9:30 Minutes: Flames penetrate plywood on calibration test.

Post Calibration Test surface.

Test B: Apex Foam's Earthseal 0.5:

1:40 Minutes: Flames impinging foam surface no ignition of foam.

3:40 Minutes: Intermittent ignition of foam.

8:30 Minutes: Foam Ignition Ceased.

9:50 Minutes: No burn through.

20:40 Minutes: Crib falling apart.

26:00 Minutes: Test Terminated.

Conclusion:

The results of the fire tests indicate the amazing fire resistance properties on the part of the Apex's Earthseal 0.5R product. These results are groundbreaking. A typical foam product that passes this test records only a matter minutes better then the bare plywood / calibration test. This is the first spray foam insulation product ever to last so long that the flame source extinguished itself. In order to test a material of this nature the testing procedure would have to be reviewed. These tests are made to the expected failure point of the product. Apex Foam Industries' Earthseal 0.5R Superior flame properties outlasted the official test.
