Majvest 200

SIGA Majvest 200 is a high-performance, mechanically fastened exterior façade membrane designed to provide permanent protection against wind and rain while remaining diffusion-open.

The 1.5 m × 50 m (59" × 164') roll provides 75 m² / approximately 807 sq. ft. of coverage. Its three-layer construction is tear-resistant, flexible and designed for fast, secure installation on exterior wall assemblies.

Majvest 200 protects the wall structure and thermal insulation from exterior weather while allowing water vapour to diffuse outward. Printed cutting and bonding guides simplify installation and detailing on site. This version does not include an integrated adhesive strip.

SIGA Majvest 200 is a high-performance, mechanically fastened exterior façade membrane designed to provide durable protection against wind and rain while remaining diffusion-open.

This 18" × 164' roll provides a narrower format for building-envelope applications where a full-width membrane is not required. It is well suited for detailed exterior wall areas, transitions and smaller sections requiring a vapour-permeable weather-resistant barrier.

Majvest 200 helps protect exterior wall assemblies and thermal insulation from weather while allowing water vapour to diffuse outward.

SIGA Majvest 200 is a high-performance, mechanically fastened exterior façade membrane designed to provide durable protection against wind and rain while remaining diffusion-open.

The extra-wide 3 m × 50 m (9.8' × 164') roll provides approximately 1,614 sq. ft. of coverage, making it ideal for large exterior wall areas where fewer membrane seams and faster installation are desired.

Majvest 200 protects exterior wall assemblies and thermal insulation from weather while allowing water vapour to diffuse outward. The large 3 m format can reduce the number of horizontal seams compared with narrower rolls, helping speed up installation on larger wall assemblies.
