WINDOW GLASS TYPES AND OPTIONS


DESCRIPTION DOUBLE PANE GLASS

  • Glass sealed unit consists of two layers of 4mm glass, which is 33% thicker than industry’s standard required for most residential glazing.
  • One of the glass surfaces is coated with LowE coating which reflects heat and cold.
  • Glass layers are separated by the “warm edge” spacer. This spacer is a foam-like material which does not transfer temperature from glass to glass and helps reduce condensation around the edges of the window.
  • The space between the two panes of glass is filled with 90% Argon Gas, which helps lower thermal conductivity.

BEST APPLICATION

  • This is is the most cost efficient and practical system for most houses that are located in climate zones 1 and 2.
  • Home owners who maintain normal levels of humidity inside their house, are using ventilation fans in bathrooms and kitchens, have few indoor plants.

DESCRIPTION TRIPLE PANE GLASS

  • Glass sealed unit consists of three layers of 3mm glass. One or Two of the glass surfaces are coated with LowE2 coatings which reflect heat and cold.
  • Glass layers are separated by the “warm edge” spacer. This spacer is a foam-like material which does not transfer temperature from glass to glass and helps reduce condensation around the edges of the window.
  • The space between the three panes of glass is filled with 90% Argon Gas which helps lower thermal conductivity.

BEST APPLICATION

  • This is is the most efficient glazing system for most houses that are located in climate zone 3.
