Dryvit’s Drysulation is a cost-effective external wall insulation (EWI) system suitable for use on 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 the interior environment and minimises thermal shock.

Drysulation has been independently certified for use with either standard (white) or high performance low lambda grade (grey) expanded polystyrene (EPS) to meet the thermal needs of all wall and building types. It also has a wide range of finish options to suit architectural requirements.

  • Design freedom. Drysulation can be installed over a variety of solid substrates. EPS insulation is lightweight and can be cut or grooved to various shapes and surface patterns.
  • Energy efficiency. Drysulation enables new or existing buildings to meet strict energy efficiency requirements. The option to incorporate high performance low lambda EPS assists in meeting even the most demanding carbon management plan. Heating or cooling costs are demonstrably lower compared to other exterior materials.
  • Weatherability. Dryvit EWI systems 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. The system can be designed to provide a 60 year durability.
  • Aesthetics. Dryvit finishes are available in a wide array of textures in both standard and custom colours.
  • Cost effective. Drysulation is easy to install and routine maintenance is minimal.
  • Testing. Drysulation has ETA certification and independent certification from BBA. Dryvit manufacturing plants are ISO 9001 certified, demonstrating the highest standards of quality and consistency.
