Outsulation® Rail

Dryvit’s Outsulation Rail is a moisture drainage external wall insulation(EWI) suitable for use on either new construction or refurbishment projects. As with Outsulation® this system is based on a simple premise – insulation is more effective when placed on the exterior of a building. Due to the increased demands for wall systems to be able to drain away incidental moisture, Outsulation Rail has been developed to incorporate a moisture drainage plane and drained cavity, respectively. By bringing insulation to the outside of external walls, this moisture drainage EWI eliminates thermal bridges; stabilizes interior environments; minimizes thermal shock; and expands upon the proven weatherability of Outsulation by adding a second line of defence against air, moisture and weather.

Benefits:

• Design freedom. The system can be installed over a variety of substrates. Expanded polystyrene (EPS) insulation is lightweight and can be cut or grooved to various shapes and surface patterns.

• Energy efficiency. Outsulation Rail enables new or existing buildings to meet strict energy efficiency requirements. Heating or cooling costs are demonstrably lower in lieu of other exterior materials.

• Air and moisture barrier. Dryvit’s Backstop NTTM weather-resistive membrane prevents water penetration and eliminates air infiltration. Unlike traditional woven sheet breather membranes it enables faster and unhindered installation of the Outsulation Rail holding track over sheathed substrates.

• Moisture Drainage System. The system has moisture drainage detailing which will evacuate incidental moisture that may enter the building envelope at terminations or penetrations.

• Weatherability. Dryvit products are formulated to provide the utmost in weather protection providing a resilient barrier against the elements.

• Durability. The combination of system components provides unsurpassed long-term durability meeting design requirements for use in virtually any location.

• Aesthetics. Dryvit finishes are available in a wide array of textures in both standard and custom colours. Our speciality finishes enable designers to replicate a variety of real stone or brick finishes from limestone to granite at a fraction of the cost.

• Cost effective. Outsulation Rail is adaptable to complex project details. Installation is rapid, and routine maintenance is minimal.

• Testing. Independently certified by international test bodies. Dryvit manufacturing plants are ISO 9001:2000 certified, demonstrating the highest standards of quality and consistency.
