hydra breathable

FT Synthetics HYDRA is a breathable synthetic roofing underlayment designed to add an extra layer of protection from water penetrating your roof, and at the same time help the release of trapped moisture due to poor attic ventilation. HYDRA is designed with an internal monolithic membrane. This structure provides outstanding vapor permeability using an advanced chemical transfer of water vapor and acts as a liquid water barrier under all weather conditions. HYDRA includes our slip-resistant GRIPSPOT™ technology top surface for superior walkability and HYDRY™ technology for faster roof deck drying.

HYDRY™  Technology*

Now features our exclusive HYDRY™ technology designed to tackle the problem of water on the roof deck during installation. Non-breathable synthetic roofing underlayments will trap liquid water on a roof deck which can quickly lead to mold growth and possible roof deck rot. Other breathable roof underlayments don’t perform much better and are slow to move liquid water from the deck. HYDRY technology quickly absorbs water from the deck and transfers it at a rate 15 times the leading breathable synthetic underlayment in the market and 10 times traditional #30 felt.
