ThermaFast® J-Track

TSN_Rigid_Insulation_System_J-Track

ThermaFast® J-Track is a component of TSN's ThermaFast Rigid Insulation Framing System, used in conjunction with ThermaFast Z-Track and Corner Angle to secure rigid foam insulation simply and quickly. 1" thermal tape comes preinstalled to each track.

Value

  • Wide flanges for increased target area for screws when installing sheathing or alternative finishes
  • Thermal tape pre-installed for universal application
  • Mill-certified high strength steel and added galvanized coating layer
  • ThermaFast J-Track utilizes typical screws to attach rigid foam insulation.  Specialty fasteners with washers are not required.

Table Notes
  • Mxa is the ASD moment capacity in the gravity load direction based on 24” o.c. fastening to stud max.
  • Mya is the ASD moment capacity in the wind load direction based on 24” o.c. fastening to stud max.
  • Attach track with minimum (1) #10-16 self-drilling screws to each stud. (2) screws may be required for high design wind pressures (higher than 30 psf service level)
  • Refer to project specification and/or architectural sections for wall assembly details related to fire and acoustical performance as well as water resistance.
