Manufacturing facilities
in our plant
Marlboro makes its insulated glass units (two or three panes of glass in a hermetically sealed unit) in-house, from scratch.
Intelligent
Glass Science
A window's energy efficiency depends,
in large part, on the type of glass used.
-
Energy Efficient
Help control energy inside and out with a full range of ClimaGuard® Low-E products formulated for every North American region and climate.
-
Safety & Security
High-strength glass that helps protect against violent storms and break-ins.
-
Sound Control
Glass solutions that reduce noise from traffic, construction, neighbors and airports.
-
Fade & UV Protection
Products that block 99.9% of the sun’s UV rays for superior fade protection.
-
Privacy
Acid-etched, patterned glass substrates and more.

Our insulated glass units have
a full range of features and options
to improve energy efficiency
-
Insulating dry airspace between its two panes
-
Desiccant to prevent condensation
-
Warm edge spacer to further reduce
heat and air transfer
Airspaces can also be filled with argon gas
and double-sealed to enhance the window's
insulating performance.
We also offer a full range of glass coatings,
including soft coat low-emissivity (low-E)
and hard coat low-E, which can help reduce cooling and heating costs.

Glass that you can choose for your Insulated Glass Unit made in our plant.
Standard = Guardian 80/70 (Low E)
Platinum = Cardinal 180/i89 (Low E)
U-Value
In a cold climate a good U-factor for a window is between 0.965 and 2.214. (That,'s between R-6 and R-2.5). Lower is better with U-factor, the opposite of R-value, when higher is better.
Energy Rating
Energy Rating (ER) is a value demonstrating the balance between U-factor, solar heat gain coefficient (SHGC) and air leakage. The higher the number, the more solar heat the product gains.
