Thermal Envelope Specialist: Murphy’s CELL-TECH – John B. Unger Murphy


Murphy’s CELL-TECH was responsible for Thermal and Sound Attenuation Insulations, and responsible for the Air-Barrier Integrity of the building shell.  The complexity of the structure included the 1850’s original building, a 1930’s addition, and 2005 new addition.  The older building areas created additional challenges because of restrictions to access in order to preserve the building’s Historical value.  Combining all the structures into one high performance energy efficient thermal shell required creative ingenuity and standard installation techniques.  The challenge was exciting and achievable.

NuWool Engineered Insulation was used throughout most of the structure.  Closed-cell foam was used in the oldest roof rafter areas where the rafter depth was too narrow to take advantage of NuWool’s lower cost, and it was used on below grade wall areas where potential moisture/water was a concern.   The complete roof system is designed to perform without a vent, and the NuWool insulated portions are warranteed for the life of the building.   

The NuWool product contributed to the points required to earn the LEED Silver Award.  Product Manufactured within 500 miles of the building site – Contributing to earn up to 2 points. Recycled content is 85% – Contributing to earn up to 2 points.  Murphy’s CELL-TECH insulation work and air-barrier integrity work on the building, along with all other energy efficiency decisions/choices for the building – Contributing to earn up to 10 points.
