SW Florida Regional Medical Center

Naples, FL

Southwest Florida Regional Medical Center and Gulf Coast Hospital were coming together to build a state-of-the-art new hospital with 42,000 square feet of new construction and 20,000 square feet of renovation to the current facility. Lee Memorial Health System and the architect, Perkins + Will, determined that installing an air barrier system to the building was imperative after analysis of the wall system showed the potential for condensation occurring within the wall system for different temperature and humidity parameters.

The air barrier would be installed at the inside face of the 6 inch-thick precast panels which comprises the majority of the building envelope, and at areas of CMU “backup” block behind polished face CMU.

Perkins + Will required a comprehensive system of sealants and a vapor barrier that was compatible with all of the exterior building materials, firestopping, building joint sealants, and at building expansion joints. 

Compatible sealants and air and vapor barriers were identified by Tremco's local sales and technical team.

ExoAir 110 Self-Adhered Air & Vapor Barrier Membrane was used as a transition membrane where UL fire-rated design was required at flat edges. ExoAir 120 Fluid-Applied Air & Vapor Barrier Membrane (in spray or roller-grade), a seamless, elastomeric membrane provided a fully adhered layer of protection over exterior above-grade walls.

Spectrem 1 Silicone Joint Sealant, an ultralow modulus, high-performance, one-part, moisture-curing sealant was ideal for the most demanding, dynamically moving joints. TREMstop Fyre-Sil Silicone Sealant was used in the fire-rated joints. Dymeric 240 Polyurethane Joint Sealant was perfect for the dynamically moving building joints.
