THERM file design and BC for Nail & Retrofit Flange

[Kawser H.]

Hi Everyone,

I have a quick question regarding nail and retrofit flange configurations. For example, a fixed window may have multiple frame options -block frame, nail flange, and retrofit flange.

My question is: during simulation, should we only model the block frame option, or do we need to perform separate simulations for each frame type?

If individual simulations are required, how should we model the THERM files for the nail and retrofit flange options? Please note that the flanges are integrated into the profile design and are not separate extensions.

I have attached a reference image for clarity.

Thank you,
Kawser
