    WeatherLogic is an integrated sheathing and structural board system that requires no secondary wrapping. By bonding a water-resistant overlay directly to the panel during construction, all the edges are sealed and then secured with seam and flashing tape to form a complete air-and-water-tight membrane system.

    This permanent membrane is designed for vertical applications and therefore ideal for curbs and parapet walls. With a peel-and-stick application, the self-adhering barrier makes installation easier and faster.

    USG and Tremco commercial sealants and waterproofing teamed up on a new barrier system, Securock ExoAir 430 System. The glass-mat sheathing panel is factory coated with Tremco’s ExoAir Brand of high performing air-water barrier fluid membrane to mitigate air infiltration, exfiltration, and water penetration. Factory application eliminates field-application inconsistencies and weather challenges and results in simplifying and speeding the construction cycle. The panel is installed using Tremco’s sealants and transition membranes to achieve air-water barrier continuity.

    James Hardie’s trademarked MircoTech coating keeps moisture from soaking into the membrane without compromising ventilation so that water vapor can escape from the inside. The system is ideal for both cold, humid climates and hot, humid environments.

    This unique weather barrier-screening hybrid for stucco and manufactured stone facades combines a rainscreen system with preinstalled fiberglass lath. The ventilated exterior coating wicks moisture from the outside while simultaneously providing open air flow for moisture to escape from the inside.
