Wetguard 200 SA

SIGA Wetguard 200 SA is a high-performance self-adhered, waterproof and airtight membrane designed to protect mass timber and wood-based building components from moisture during the construction phase.

Its fully self-adhered design provides reliable protection against rain and standing water while helping keep timber assemblies dry before the building is fully enclosed. The membrane is designed for temporary weather protection of horizontal and slightly inclined wood surfaces during construction.

Wetguard 200 SA features a pressure-sensitive adhesive for secure bonding and a durable, slip-resistant surface for safer movement across protected areas during installation. The membrane can remain exposed to weather during the construction phase while providing continuous moisture protection.

The 15" × 164' narrow-format roll is well suited for perimeter areas, transitions, detailing and narrower mass-timber components where the full-width Wetguard membrane is unnecessary.

SIGA Wetguard 200 SA is a high-performance self-adhered moisture-protection membrane designed to protect mass timber and wood elements from moisture during the construction phase.

Its robust, rainproof construction provides reliable moisture protection while maintaining drying potential. The membrane features a transparent, non-slip surface, allowing the substrate to remain visible while providing a safer working surface during construction.

The 61" × 164' roll provides approximately 839 sq. ft. of coverage, making it ideal for full-surface protection of large timber floors, CLT panels and other wood-based assemblies during construction. Your Canadian dealer sheet confirms the 1560 mm × 50 m roll and 839 sq. ft. coverage

SIGA Wetguard 200 SA is a high-performance self-adhered moisture-protection membrane designed to protect mass timber and wood elements from moisture during the construction phase.

Its robust, rainproof construction provides moisture protection while maintaining drying potential. The transparent carrier features an anti-slip surface, helping provide safer movement across protected timber surfaces while allowing installers to see the substrate below.

The 30" × 164' roll provides approximately 420 sq. ft. of coverage and offers a useful intermediate width for timber floors, panels, transitions and areas where the full 61" membrane is unnecessary. SIGA specifies 32 rolls per pallet for this size
