Window 7.8.57 - Fritted glass

[Nam, Lê Hoài (QDP)]

Hi, 
I am calculating the U-value for the glass.

I have a problem that I can't create a new fritted glass in WINDOW 7.8. So is there any way that I can create a new fritted glass or change the glass substrate of your own fritted glass ?

Hi,

> So is there any way that I can create a new fritted glass ?

We have deprecated the old (W6.3) methodology with the implementation of the direct-diffuse (dir/dif) method for light-scattering data in WINDOW 7.8.71.

Examples and general overview is found on our web site:

https://windows.lbl.gov/cgdb-submitting-data

under the section CGDB Diffuse glazing submission process

Detailed instructions about measurement is given in NFRC 300 and 301 technical documents available from NFRC.org

I hope that get you started.

> or change the glass substrate of your own fritted glass ? 

We have not yet implemented the ability to modify the substrate of light-scattering products.

/best,

Jacob
