Project: Attic Retrofits Using Nailbase Insulated Panels:
Retrofit of attics in older existing homes can help improve energy savings and occupant comfort. For some attic types the process is simple - air seal and add insulation at the ceiling, but for many older attic types improvements are more challenging.
The primary goal of this project is to develop and demonstrate a value-added roof/attic retrofit solution using nailbase insulated panels for a range of older homes where traditional attic insulation approaches are not effective or feasible.
Enable improvements to energy efficiency, comfort, and durability for a large population of older homes by providing integrated strategies for retrofitting attics using nailbase insulated panels.
Prefabricated panels provide added insulation and structural nailbase backing for roofing, and their installation can be integrated during a re-roofing effort

Types of attics in older homes not suitable for standard “pile-on insulation” upgrades (typical location of existing insulation is shown; insulated panels are not shown)
(1) Cathedral Ceiling:
(2) Habitable Attics:
A single solution can be employed to help transform these attics and ultimately the house into a better performing system using prefabricated nailbase insulated panels.
Nailbase Insulated Panels consist of rigid foam insulation laminated to a wood structural panel
