Mass Timber Moisture Protection Strategies

SlopeShield Plus SA

 

SlopeShield Diagram WebImage 01

 

SlopeShield Plus SA protects mass timber from bulk water intrusion and concurrently dries mass timber through moisture vapor diffusion.

Taped Splines

Alternative protection such as taped splines will leak and less durable lower perm sheet goods offer little to no drying capacity resulting in water damage and mold.

Revolutionary Roofing Underlayment

VPPCT Gold Badge

SlopeShield Plus Self-Adhered’s high drying capacity and black coloration (which absorbs heat from the sun when exposed during construction), accelerates the drying process of the underlying materials.

This combination helps to mitigate construction moisture which would otherwise be trapped by a non-permeable roofing underlayment.
