BPS 2000 screen cloth is constructed of an extruded vinyl coated Kevlar yarn, which is woven into a fabric, heat sealed, binding the warp and weft yarns into a non-raveling matrix.
Construction:
Warp: 13 ends per inch – 3000 denier Kevlar, vinyl coated.
Filling: 11 ends per inch – 1000 denier Kevlar, vinyl coated.
Theoretical one (1) inch tensile strength:
Warp: 3000 denier @ 150 lbs. x 13 = 1950 lbs. per inch
Filling: 1000 denier @ 50 lbs. x 11 = 550 lbs. per inch
Flame Resistance:
Tested under NFPA 701-99 small-scale vertical burn– Pass.
Visible Light Transmission: T.B.D.
Estimated % of Openness: T.B.D.
S.C. with 1/4” clear glass: T.B.D.
Performance Characteristics – Real World Testing
The Department of State with the Army Corp. of Engineers tested the BPS 2000 screen cloth at a Government test facility in a building with a full size window. The BPS 2000 screen cloth was appropriately anchored to the building's floor and ceiling.
A subsequent test explosion with a peak pressure of 35 psi and impulse of 250 psi-ms (milliseconds) resulted in the BPS 2000 shadecloth containing the glass fragments and frame within the immediate vicinity of the window. Based on the test result of the BPS screen, this product was deemed acceptable by the testing authorities and demonstrated that it not only met the design criteria requirements, but substantially exceeded them. The BPS 2000 product far exceeds GSA Blast Mitigation requirements, which we are advised is now under review.
