All Delco glass packages are produced using advanced hot-melt spacer technology designed to provide industry-leading gas retention and long-term energy performance
Delco's Low-E Coating is the highest base standard glass for Canadian climates throughout Toronto, the GTA, and Ontario areas. It raises the bar and creates the new EnergyStar standard for all of Canada.
Available in dual or triple glazed, the sealed unit itself is engineered to provide protection from the elements while being durable enough to last for decades.
A nearly microscopic coating of metal-oxide, the coating acts as a reflector of UV and IR rays. Acts like sunscreen, but for your home.
Along with the window frame, the spacer bar protects against thermal transfer along the edges of the glass. Available in foam, stainless steel, or aluminum.
A completely inert noble gas, argon acts to slow down convection currents inside the sealed unit. Provides greater insulation to the unit regardless of Low-E coating.
The unique coating on the outside of the window creates a thermal barrier that help make your home fully insulated, while having plenty of natural light, creating passive solar heating.
Sun-shield packages are designed to block unwanted heat and UV rays from the sun and increase R-values.
Traditional 7/8" double glazing options, can accommodate 1-1/4" for all sliders and hung windows. Triple glass packages will qualify for high energy-rating standards. The 1-3/8" and 1-1/4" triple glazing options will also eliminate the need for expensive Krypton gas and/or unnecessary extra Low-E glass that could reduce the IG life expectancy due to excessive heat buildup.
Triple pane technology is designed to reduce the window's heat conductivity and stop the cold from getting inside the house. To achieve this, Argon or Krypton gases are utilized to fill the space between the panes. Both gases conduct up to 50% less heat than air, and when coupled with triple pane construction you get added protection against heat loss, condensation and cold weather. Less heat loss translates directly into more energy cost savings for you.
