Laminated glass dataset

Question

Hello all,

I cannot find laminated glass in OpenLCA Ecoinvent database. Do you know if it has another name, or where can I find it? I have two single glass panes and there will be PVB (Polyvinyl Butyral) between them. I would like to know how much electricity, PVB and heat will be needed. 

Many thanks for your help!

Answer 1

There is some laminated safety glass with double glazing in ecoinvent called "glazing production, double, U<1.1 W/m2K, laminated safety glass". You can try to take this as a starting point and replace PVC in the inputs with PVB. There is no PVB in ecoinvent, but you can find inventories for the supply chain of producing PVB in some excel files that are used for photovoltaics inventories with PVB:
