Hello Therm Forum.
I'm hoping someone can help me on this forum.
I have some thermally broken aluminium frames for which I would like to know the Uf calculated to NFRC-100.
Is there anyone who can help me with this?
There are 3 different frames.
1 Fixed window
2 Casement/Awning
3 Sliding
Any help would be appreciated.
Kind Regards
Theike
