UBC STANDARD 15-2 CLASS”A” FIRE TESTS SERIES

Client: WEDGE-IT CO.

Date of test: May 6, 2000

Type of Test: Class “A” Burning Brand ASTM #-108/UBC STD. 15-2ul 790

REASON: VERIFICATION OF MAINTAINING CLASS A RATING LABORATORY NUMBER: 11553 RAMTECH LABORTATORIES INC

REASON:

The fire test series were conducted to show that WEDGE-IT Expanded Polystyrene (EPS) boards would not in any way degrade the Class “A” fire rating of a typical concrete or clay tile roofing assembly. EPS foam is supplied by Premier Industries, Inc./DBA Insulfoam which has an ICBO, ES Report No. ER—3414. Wedge-It tapered boards are produced in several sizes and thickness’ to accommodate the numerous roofing tile configurations that are being produced for today’s market place.

TEST:

The heat-affected area was confined to the immediate area of the brand placement and marginally above the brand. There was no displacement of the concrete tile observed during or after the tests. Also, there wasn’t any distress noted on the WEDGE-IT boards on the test deck specimens throughout the exposure period. Removal of the Type 30 underlayment indicated the plywood deck was discolored from the melting asphalt but there were no signs of charring on the plywood. Based on the results of these Burning Brand Tests, it is our professional opinion that the WEDGE-IT Roofing system easily meets the Class “A” Burning Brand Requirements.

CONCLUSIONS:

The results of Fire Classification test, in accordance with ASTM E-108/UBC Standard 15-2 for Class A Burning Brand and Class A Intermittent Flame Exposure, show that the WEDGE-IT EPS boards, when installed directly over Type 30 underlayment, and directly below the roofing tile meets the Class A Roof Fire Classification.
