BiLar™ is a multi-component Class A vapor barrier composed of a
highly puncture-resistant tightly woven fabric coated with a strong,
low perm, and long lasting polyolefin resin.
BiLar is designed for use as a high-performance vapor barrier
under slabs, permanent liner in sealed crawl spaces, in vertical
waterproofing, and flashing applications.
BiLar provides more abrasion and puncture resistance than standard 15 mil poly sheeting.
Standards:
• BiLar is a composite product consisting of a tightly woven, puncture resistant polypropylene fabric laminated on both sides with a 4 mil polypropylene extrusion.
• BiLar is available in 5’ and 10’ widths in lengths of 150’. BiLar weighs approximately 32lbs/Msf.
• BiLar exceeds standards set forth in ASTM E-1745-97 for plastic water vapor retarders used in contact with a soil or granular fill under concrete slabs.
Applications:
• Vertical waterproofing
• Horizontal waterproofing
• Under slab vapor barrier
• Crawl space vapor barrier
• Crawl space encapsulation
• High-performance flashing
