ThermaFast® Corner Angle


ThermaFast® Corner Angle is a multi-purpose 90° angle used in a variety of framing applications, including soffits, floor and ceiling runners, and wall bridging.  It is the final piece in TSN's ThermaFast Rigid Insulation Framing System used to secure rigid foam insulation simply and quickly.  ThermaFast Corner Angle is manufactured from mill-certified, galvanized steel.


  • Wide flanges for increased target area for screws when installing sheathing or alternative finishes
  • Only mill certified high strength steel is used
  • ThermaFast Corner Angle utilizes typical screws to attach rigid foam insulation.  Specialty fasteners with washers are not required.
