SW Florida Regional Medical Center needed to account for adjusting temperatures

Naples, FL

Southwest Florida Regional Medical Center and Gulf Coast Hospital were coming together to build the area’s most 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. 

Particularly when protection from air and vapor infiltration is as critical as this one, having local sales and technical representatives available to help guide in the selection of the right products for the application and to meet design requirements, instills the architect and general contractor with the confidence that the solution will meet their requirements.

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 for 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 ideal for use on the most demanding, dynamically moving joints. TREMstop Fyre-Sil Silicone Sealant, a single-component, neutral cure, silicone firestopping sealant capable of +/- 25 percent movement in a fire-rated joint. Dymeric 240 Polyurethane Joint Sealant, a multi-component, chemically curing, epoxidized polyurethane sealant specially formulated for dynamically moving building joints.
