MOBILE-FLEX™ Bottom Board
A special bottom closure material uniquely woven using high density polyethylene (HDPE)
that is then coated with a continuous layer of low density PE.
What this creates is a material that is uniform in quality, with no weak spots, that is completely impervious to water and also meets the requirements for use as a vapor barrier. It’s Beach puncture test resistance is more than five times the requirements as established by HUD! Staple hold out is excellent. Penetrations and cuts will not spread and can be easily patched using our FLEX-MEND® tape.
Durability
MOBILE-FLEX has been tested for durability and weather-ability, as well as chemically tested to ensure maximum performance. After seven years of continuous, direct exposure to the elements in Arizona, the material retained more than 70% of its strength.
Flammability
Classified by Underwriters Laboratories, Inc., as to surface burning characteristics. MOBILE-FLEX tested out to zero flame spread and zero smoke developed. The tests were conducted in accordance with UL Standard Test Method for Surface Burning Characteristics of
Building Materials, UL 723.
Moisture Control
Totally impervious to water. Its strength can not be adversely affected by moisture. Because of its black polyethylene coating, MOBILE-FLEX qualifies as a vapor barrier. Technical report #19757 from Chicago Paper Testing Laboratory, Inc., reports the material to have an average perm rating of 0.037.
