VaporBlock®20 Plus (20 mil)- The Poly Sheeting Gas and Mold Blocker- 7 layer co-extruded barrier AKA Radon Plastic Vapor Retarder


VaporBlock 20 Plus plastic sheeting is a 20 mil polyethylene, high performance vapor barrier intended for under-slab applications where soil-borne gases like radon are a concern. VaporBlock 20 Plus (radon plastic) is 50 times less permeable than typical high-performance polyethylene vapor retarders. This is due to its tight cell structure.Superior unmatched impact strength for both under-slab and vertical wall applications.
VaporBlock 20 Plus is one of the most effective underslab vapor
barriers in the building industry today far exceeding ASTM E-
1745 Class A (Plastic Water Vapor Retarders Used in Contact with Soil
or Granular Fill Under Concrete Slabs). The 20 mil thickness is designed to meet the most stringent requirements.
VaporBlock 20 Plus is produced within the strict guidelines of our
ISO 9001:2000 Certied Management System.
This gas blocker is much less expensive than comparable products. A 10-foot-by-150-foot roll costs about $470. For radon blocking, seams should be sealed with a special foil-backed tape (VBP4VB Plus Tape) that costs $32 per 4-inch-by-210-foot roll.
