[MassHistPres] Celuca windows

[Dennis De Witt]

Also called Celuka -- It is a variation on ordinary PVC which is  
extruded into thicker shapes because under a smooth exterior skin it  
has a foamed core.  This would make it stronger -- per a comparable  
weight -- and better insulating (but only with respect to the frame  
not the much larger glass area).  However, PVC is still considered a  
hazardous material in some European countries (unfortunately for  
them, Europe has also been the epicenter of the development and use  
of PVC window technology) and it is still subject to UV degradation  
in the long run.

It seems to be being pushed by traditional low cost PVC replacement  
window companies like Newpro.

And, of course as insulating glass windows they are guaranteed to  
fail in 15-25 years and will need replacement.  That's why they are  
called "replacement windows".
