Retrofit Insulated Panels
Retrofit insulated panels (also called nailbase panels) provide continuous exterior insulation and a solid nailing surface in a single step. Perfect for deep energy retrofits and new construction, retrofit insulated panels are a labor-saving method of reaching a high-performance, airtight building envelope.

Retrofit Insulated Panel Case Studies
Case Study: Cold Climate Retrofit. Applying retrofit insulated panels to this classic craftsman home helped cut energy use by 50 percent and bring the HERS Index down to 59, saving the homeowners over $1,300 a year in energy costs.
Case Study: Oak Harbor Retrofit. An old ranch-style home gets a much-needed remodel, complete with retrofit insulated panels, high performance windows and a new HVAC system. The improvements resulted in a 64 percent reduction in energy use and $3,060 in annual savings for the homeowners.
Field Studies on Retrofit Insulated Panels
Extensive research by NYSERDA, Home Innovation Research Labs and DOE Building America confirms the energy-saving benefits of retrofit insulated panels.
