How much more expensive (percentage wise) do you think DG units with Pilkington Optiphon laminated glass would be compared to DG units with standard double glazing glass?
Alternatively, could two sheets of "regular" laminated glass (each of different thickness) be used in a DG unit to give a more affordable way of providing sound insulation? Sound insulation against traffic noise about 5 metres away from windows.
Thanks
