ThermaFast® Z-Track


ThermaFast® Z-Track is a component of TSN's ThermaFast Rigid Insulation Framing System, used in conjunction with ThermaFast J-Track and Corner Angle to secure rigid foam insulation simply and quickly. It is installed between every 24" rigid foam insulation and incorporates bumps to engage and hold foam in place during installation. 1" thermal tape comes preinstalled to each track.


  • Rigid insulation foam engagement feature keeps rigid insulation from sliding or popping out of place without the need for specialty fasteners with washers
  • Utilizes typical screws to attach rigid foam insulation
  • 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

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.
