Reply To: Secondary Glazing

Hi Norman, your feedback is interesting, is there a formula or method around the impacts of glass thickness, vs the size of gap.  For simplicity – assuming standard glass and just good old household air in between the gap.

I realise that the window frame may dictate what will work and what won’t, but is there a formulation or rules of thumb that guide thickness of glass and gap impacts on performance?
