Majvest 500 SA 18"
SIGA Majvest 500 SA is a vapor-permeable, 3-ply membrane, with the reverse face fully coated by a pressure-sensitive glue for direct bonding to substrates. The adhesive side of the sheet is protected by a white, siliconized, split-release liner which is removed during installation. Primer-free adhesion to most common building materials, including concrete, plywood, gypsum, and metal. Narrower 18” roll size, for use in construction sequencing, pre-stripping, and smaller sections of the wall field in above-grade wall applications.
