SIGA Majvest 500 SA – 60" × 100' (500 sq. ft.)
SIGA Majvest 500 SA is a high-performance self-adhered, vapour-permeable exterior air and weather barrier membrane designed for direct application to common building substrates.
The 60" × 100' roll provides 500 sq. ft. of coverage, making it ideal for full-wall applications where fast installation and continuous exterior protection are required.
Its reverse face is coated with a pressure-sensitive adhesive that bonds directly to common substrates including concrete, plywood, gypsum and metal without primer in most applications. This helps reduce installation steps, labour and additional materials on site.
Majvest 500 SA also features a 50/50 split, tear-resistant release liner for easier positioning and installation. Its strong adhesion at both high and low temperatures makes it suitable for year-round construction
