Williamsport Hospital
Project Overview
Williamsport Regional Medical Center, a state-of-the-art facility that’s part of the Susquehanna Health System, underwent a $250 million dollar construction and renovation project to improve and expand patient services in central Pennsylvania.
System: Staycell ONE STEP® 502 Intumescent Spray Foam Insulation
Application: Precast Concrete Walls
Location: Williamsport, PA
Project Size: 50,000 square feet
Efficient Building Envelope
The exterior walls of the newly constructed Susquehanna Tower consist of energy efficient windows set in 5” thick rectangular pre-cast concrete assemblies bolted to a structural frame. The original specifications called for a spray-applied air/moisture barrier insulated with rigid foil-faced insulation. After careful performance and cost analysis the specification was switched to spray polyurethane foam insulation, which provided the client higher performance at a significantly lower cost.
The application called for 3” Staycell ONE STEP® 502 intumescent spray foam insulation foam applied to all interior surfaces of the wall assemblies. Prior to application, PSI conducted a WUFI analysis (hygrothermal building modeling program used to predict moisture and thermal transport in building envelope systems over a period of time) to confirm thickness and performance.
Key Benefits
