Comprehensive Mass Timber Moisture Protection


Having installed over one million square feet of SlopeShield Plus SA throughout the country, VaproShield has earned a reputation as a trusted partner in creating mass timber protection plans.

Minimize Moisture, Minimize Risk, Maximize Drying

As mass timber construction gains popularity, establishing a comprehensive moisture protection strategy is essential for both the construction phase and the long-term success of your building. As a general contractor, builder, or installer, you can prevent costly damage by using SlopeShield Plus SA: a high drying capacity self-adhered membrane. It offers dual benefits: simultaneously protecting and drying your mass timber structure.  Wet Mass Timber WebImage 01
  A comprehensive moisture protection strategy is needed to avoid checking, staining, dimensional changes which can lead to compromised structural values.

WallShield IT (green) temporarily protects beams and framework during construction from moisture infiltration, UV damage, wood discoloration, and is easily removed at the end of the project to showcase the beauty of the wood structure.

Tough and Durable

End grains are especially susceptible to water intrusion. By allowing SlopeShield Plus SA to overhang the structure, end grains are protected when water is squeegeed from the deck after and during rain events.
