There seems to be a bit of confusion as to the make up of the new triple glazed units due to be brought to market. So I’ve found two images showing the two different set up’s that are being advertised. But the confusing factor here, is that the two images below are from WHS Halo, which system are they going to use?

Both systems claim to achieve a U-value of 0.7. But one of the obvious problems I can with the system housing the single pane of glass is condensation. Will that set up cause it?

Personally, the triple glazed one unit set up is the better option. Fitters still only have to glaze one unit, there’s no need for a second bead, and potential condensation shouldn’t be a problem.
