Port Townsend City Hall
C and F Insulation was hired to perform the delicate job of insulating the historic and newly updated clock tower. It is a focal point for the entire city. R-30 insulation value was installed using a unique "Stickpin" technique with rigid insulation.
Stick pin hangers are insulation hangers with a self-stick base. This is a common retrofit installation for clean steel surfaces like metal buildings. This technique utilizes a "stick pin" that is glued onto the steel panel surface then used as a hanger for the insulation blankets.
Once the insulation blankets are installed over the stick pin, a friction washer is placed over the pin to keep the insulation in place. You get a rather handsome "quilted" look.
