Our Products

Baywest STM

(Sill Trough Membrane)

Baywest STM is a high-performance self-adhering membrane designed for use as a pan flashing in the rough openings of windows and doors. Featuring a tri-layer engineered film and a high-tack, pressure-sensitive adhesive, Baywest STM provides puncture and tensile strength along with waterproof tie-in layers for added bond strength. It can be applied at temperatures as low as -28°C without the need for primer or mechanical fasteners, ensuring a durable and reliable seal.

Envelope Sealant

Our Envelope Sealant is a National Building Code compliant product with CCMC approval, offering superior protection against moisture buildup. This single-component, non-sag elastomeric polymer forms a closed bond wherever applied, securing your windows and doors effectively. Its elastomeric properties allow it to stretch and move naturally with the building, maintaining a perfect seal over time. Envelope Sealant requires no primer, cutting, or stapling, and is backed by a comprehensive 7-year warranty protection plan for added peace of mind.
