Sheffield NFRC Lookup Problem and VT Numbers

#1 Post by InfoSponge » Tue Jan 17, 2006 2:38 am

Does anyone know how to lookup Alside Sheffield double-hung windows on the NFRC web site? It looks like it is the Alside model 0501 for double-hung and 0502 for horiz sliders (according to http://www.afhii.com/ALSIDE%20WINDOWS/Alside%20data.htm), but I don't see those models or the Sheffield name anywhere in the CPD search area. Am I just stupid or are they not there?

Many of the alside windows like the model 601 (UltraMax?) double-hung models don't list a VT number (they just have a *). Is this because thay are too low and would scare off customers?

My local dealer called and said the Alside UltraMaxx and Sheffield are about the same window (NFRC-wise), with the same glass/frame but with sill differences, so the UltraMaxx NFRC numbers will match the Sheffield ones. I noticed that the air infiltration numbers are better on the Sheffield according to their well-hidden technical data here:

Now all that I am missing are some Sheffield VT numbers. The NFRC does not publish those (I wish they did for all tested windows).
