Dryvit’s Outsulation is a cost effective external wall insulation(EWI) suitable for use on either new construction or refurbishment projects. The system is based on a simple premise – insulation is more effective when placed on the exterior of a building. By bringing insulation to the outside of external walls, this barrier EWI eliminates thermal bridges; reduces air, wind and moisture penetration through the system; stabilises interior environments and minimises thermal shock.


  • 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 enables new or existing buildings to meet strict energy efficiency requirements. Heating or cooling costs are demonstrably lower in lieu of other exterior materials.
  • Weatherability. Dryvit EWI 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. Their 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 is easily adapted to complex project details. Installation is rapid, and routine maintenance is minimal.
  • Testing. Independently certified by BBA and other international test bodies. Dryvit manufacturing plants are ISO 9001: 2000 certified, demonstrating the highest standards of quality and consistency.
