  3. ThermaFast Rigid Insulation Framing

ThermaFast® 

Recent changes in the IECC Energy Conservation Code and ASHRAE Standard 90.1 necessitate the installation of 1 to 4 inches of continuous rigid insulation layer on the outside surface of exterior metal stud walls. Existing building component systems lack sufficient accommodation for cladding assemblies, like cement board panels, siding, metal panels, EIFS, stucco, etc. since there is no viable means to attach to a stable substrate like plywood or gypsum sheathing over the thick rigid insulation layer other than long and unstable cantilevered screws. 

The ThermaFast Rigid Insulation Framing System is an engineered installer-friendly set of steel framing tracks and angles designed to be an integral part of the continuous rigid insulation, and at the same time provide a stable component for direct substrate attachment.

Features
  • Pre-engineered framing system to support weight of rigid insulation, cladding material, and wind loads
  • Unique foam engagement feature keeps rigid foam insulation from sliding or popping out of place without the need for specialty fasteners with washers
  • Utilizes typical screws to attach the system
  • Wide flanges for increased target area for screws when installing sheathing or alternative finishes
  • 1″ thermal tape comes preinstalled to each track for an integrated thermal break between the steel studs and continuous insulation
  • Mill-certified high strength steel and added galvanized coating layer

Thermal Resistances

This table provides thermal performance data (R- and U-values) of the ThermaFast® Rigid Insulation Framing System produced by the Steel Network Inc. The ThermaFast System is used in exterior wall assemblies to support rigid foam insulation with thicknesses ranging from 1.0 inch to 4.0 inch. In addition, the ThermaFast System provides viable means to attach the cladding assemblies, like cement board, siding, metal panels, to a stable substrate instead of using long and unstable cantilevered screws to the sheathing layer. This summary allows designers to have fast and straightforward access to information with sufficient accuracy to reduce uncertainty in the thermal performance of building envelope components. Thermal modelling for this project was completed using a 3D finite element analysis heat transfer software package by SolidWorks®; SW Thermal Solver and follows ASHRAE/IES Standard 90.1 requirements.
