Our windows and doors include warm edge (‘Superspacer’) double glazed sealed units with low ‘e’ (Solarban 60 or Climaguard 70/36) and Argon. Low ‘e’ and Argon are combined within the optimal 1/2’’ airspace between glass panes.
As an option, triple glazing your new windows will maximize their energy efficiency. We maintain the 1/2’’ airspaces between glass panes, as this achieves optimum thermal values. Check out these supplier links for more detailed information:
