Conservatory glazing

[Dave H]

I am installing a conservatory and have been offered 28mm argon filled window units fitted with Novapanes "Nova Neutral Plus 1.1" glass which the conservatory supplier claims to be a superior unit to K glass. The Novapane

data sheet claims a thermal transmittance coefficient, U value, of 1.1 W/sqmK for the argon sealed unit.

Does anyone have any experience of this glass or the glazing units and can you advise if it is superior (or a least euivalent) to K glass. Thanks

Dave

Well 16mm argon between 4mm panes with inner of K has a U of 1.46 so it does seem quite good. How much is it compared with K ?
