Fedderlite®

Description

Dryvit’s Fedderlite is a prefabricated external wall insulation (EWI) offering fast track installation for use on either new construction or refurbishment projects. Like site applied Outsulation® this prefabricated 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 prefabricated panelized EWI eliminates thermal bridges; stabilizes interior environments; minimizes thermal shock; and builds upon the proven weatherability of Outsulation.

Benefits:

  • Fast track. The panel system enables rapid installation unhindered by environmental conditions that would normally affect traditional building methods. Panels can be installed from mast climbers or mobile towers, reducing access time and cost.
  • 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. Fedderlite enables new or existing buildings to meet strict energy efficiency requirements. Heating or cooling costs are demonstrably lower in lieu of other exterior materials.
  • Lightweight. Panels weigh less than brick, stone or precast concrete thus they limit imposed loading on existing and new build structures. Despite their lightweight nature the panels are capable of withstanding critical wind and structural loads.
  • Versatile. Dimensional adjustments can be made easily and inexpensively right up to panel assembly time. Of great advantage in retrofit or new build projects.
  • Weatherability. Dryvit 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.
  • Aesthetics. Dryvit finishes are available in a wide array of textures in both standard and custom colours. 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. Fedderlite 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.
