Panel Weight

Concrete/Steel Panels: 22.5 lbs./Sq.ft.
Steel/Steel Panels: 2.5 lbs./Sq.ft.

Panel Dimensions

All standard modular panels are 6 feet wide, and can be produced in variable lengths up to 48 feet long.  Standard concrete/steel wall panels are 8 inches thick, and steel/steel panels are 6 inches thick.  Thickness can vary depending on the amount of insulation required 

Insulation Values

All standard modular panels (walls and roof) are insulated to R-30.  Steel/steel panels can be made up to 10 inches thick and insulated to R-65.

Structural Requirements

All ThermalShell panels are attached to structural steel framing.  Wall sections require steel attachment angle anchored to the footing or foundation wall.  Sections up to 18 feet tall do not require mid-span horizontal girders.  Roof sections require joists spaced up to 10 feet apart, depending on load requirements.

Panel Connections

Wall panel connections are made by structural screws to the attachment angle at the foundation and stainless steel Fab-lok® molly fasteners to the field installed attachment angle at the girder.  Overlapping sections of interior sheet steel are contacted with insulated tape and/or steel stitch screws.

Roof panels are connected to each joist with structural screws on one side of the panel and stainless steel Fab-lok® molly fasteners at multiple points underneath each panel.

Sealants and Flashing

Depending on the connection type and location different sealant are employed.  All exterior concrete joints use a standard backer rod and exterior caulk.  Window and door jambs mounted to concrete panels are caulked as well.  Roof panels use a sealant tape or silicon caulk to reinforce their triple seal mechanism.
