[Greenbuilding] Refurbishing wooden storm windows

[arthur landerholm]

> Hi Group,
> 
> I'm refurbishing the original wooden storm windows from my 1940s brick
> colonial in the Washington DC area.  Before I reglaze the storm windows,
> it occurred to me that I might replace the original, 3/32" single pane
> glass with dual pane laminated glass.  
> 
> Does anyone know if I'll need to deepen the existing rabbets (which are
> 7/16") to accommodate the double-thickness glass?  That is, do I need the
> equivalent amount of space for the glazing compound (ie 11/32") or will
> the window be weather tight with less compound?  
> 
> Thanks.
