[Equest-users] Thermal Bridging of Steel Stud Walls

[Bishop, Bill]

Hi Paul,
Section A9.2(b) directs you to do a parallel path calculation using the modified zone method. The Modified Zone Method for Metal Stud Walls with Insulated Cavities is described in 2017 ASHRAE Handbook – Fundamentals, p.27.5.
Regards,
~Bill

Subject: [Equest-users] Thermal Bridging of Steel Stud Walls

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
