[Equest-users] Thermal Bridging of Steel Stud Walls

Wed Aug 8 07:58:22 PDT 2018

Alternately, I use the EE4 modeling program from NRCan. EE4 is a simplified GUI to DOE2.1e. It includes an envelope performance calculator that accounts for different types of thermal bridges. It has many built in materials and you can add custom materials. I use EE4 to establish the envelope performances then I define my eQuest materials and layers to match.

You would have to install EE4 using a virtual machine with XP. It won’t run on 64 bit Windows machines.

Paul,
Chapter 27.5 in the ASHRAE Fundamentals provides examples for calculating the effective R-value for where there is steel studs creating a thermal bridge.

Hi:

Does anyone know how to calculate the thermal bridging of steel stud walls?  I have a wall with 6" metal studs, 16" OC, with R39 cavity insulation and R10 CI. Table A3.3.3.1 in 90.1-2013 does not go above R21.

Thank you,

Paul Diglio
