Fedderlite®

Prefabricated Exterior Wall Insulation and Finish System for Use over Solid Substrates

Fedderlite® is a lightweight panel system suitable for new builds or retrofits. Fedderlite panels can either be adhered or mechanically fastened to approved substrates, offering flexibility based on project requirements. They require a smooth, solid substrate for optimal installation. The unique construction of Fedderlite panels embeds reinforcing channels in continuous insulation, facilitating handling and mechanical wall attachment. They are ultra-lightweight (around 2.5 lb/ft²), easy to handle and install on-site. Fedderlite® panels combine efficiency, adaptability and durability, making them an excellent choice for various construction projects.

Components that Make Up a Fedderlite System
