Metal roof & underlayment (AquaGuard – DryTech)
Curious to see if anyone has used or seen the product called “AquaGuard Dry-Tech”?
It’s designed to allow airflow underneath a metal roof to drain any condensation that can form under the metal roof and it also provides an acoustical reduction in metal roof noise.
The bottom of the underlayment is NOT breathable/non-permeable and this attaches via peel & stick to the roof sheathing (OSB SIPs).
I am planning to possibly use this product on a 8″ closed-cell OSB SIP roof with a standing seam metal roof on-top. The advantage is that any water that might get past the metal roof will drain/evaporate and the peel & stick membrane will provide a waterproof and air barrier to protect the OSB skin of the SIP.
