Air gap with Thickness

Hi, I’m wondering how we model air gaps with honeybee.
In this thread, @chris suggested using the no-mass material component. But this component doesn’t have thickness properties.

Any ideas?
Thanks in advance

Hi @farzaneh.fth,

With “HB search materials” you can find the material “Generic Wall Air Gap”. This will give you some idea of the settings. You can either use this material or modify it to your own needs.
