After all, the enclosing of a building is really what sets a “building” apart from pavilions, porches, and other open-air structures.
The last of the Structural Insulated Panels are placed.
Plastic over the window and door openings allows the building space to be heated so work can continue throughout the winter.
Cracks such as these will be caulked and sealed around the entire building to provide the R-30 insulating value. SystemWorks is commissioning the building to ensure details like these are addressed during construction.
The rhythm of the exposed trusses, and the natural daylight that will come through the upper clearstory window are starting to define the natural patterns and biophilic elements integrated throughout the spaces.
