Outsulation® Rail

Dryvit’s Outsulation Rail is a moisture drainage exterior insulation and finishing system (EIFS) suitable for use on either new construction or refurbishment projects. Due to the increased demands for wall systems to be able to drain away incidental moisture, Outsulation Rail has been developed to incorporate a drained cavity.

By bringing insulation to the outside of external walls, these moisture drainage EIFS eliminate thermal bridges; stabilise interior environments; minimise thermal shock; and expand upon the proven weatherability of Outsulation by adding a second line of defence against air, moisture
and weather.

Product Benefits
  • Outsulation Rail is tested in accordance with BS 8414-1 and 2 and classified as meeting the performance requirements of BR 135.
  • Outsulation Rail enables new or existing buildings to meet strict energy efficiency requirements. The option to incorporate high performance low lambda EPS assists in meeting the most demanding carbon management plan. Heating or cooling bills are significantly reduced.
  • Dryvit’s AquaFlash and Backstop NT weather-resistive membranes prevents water penetration and eliminates air infiltration. Unlike traditional woven sheet breather membranes they offer a faster and unhindered method of installing the Outsulation Rail holding track over sheathed substrates.
  • The moisture drainage cavity removes incidental moisture that may enter the building envelope at terminations or penetrations.

Where the External Wall Insulation System must meet the requirements of a specific European or National approval it is important to check that the selected system and material combination is covered within the relevant approval document.
