We offer hundreds of glazing options to meet your energy savings, privacy, safety and design requirements.

Glazing Options & Performance

Glass or Insulating Sealed Units are the most important components of the windows. There are hundreds of glazing options and add-ons to increase energy efficiency, privacy and security and to create the distinct designs.

Low-E Glass

Supreme Windows offers both high solar heat gain(HSG) "Solar Plus" and low solar heat gain(LSG) "SolarGuard" Low-E coated glazing option to deliver the best energy and cost savings performance while reducing environmental impact.

LSG: SolarGuard & SolarGuard2

LSGLow Solar Heat Gain(LSG) glazing system with Soft Coat Low-E glass

SolarGuard is a Sealed Unit constructed with SOFT COAT Low-E(Solarban-60) glass, Superspacer and Argon gas. SolarGuard2 reaches the highest R-Value, which means the best insulation.

Supreme Windows has developed Solar-5 sealed units that achieve an R-Value of 5 using 2 panes of glass for those windows not designed to accommodate Triple Glaze sealed units such as Sliders and Single Hungs.

Solar-5 is a Double Glazed Sealed Unit with 1 pane of soft coat Low-E glass on Surface #2 and 1 pane of hard coat Low-E
glass on surface #4.

Super Spacer: "Warm Edge Technology"

LSGSuper Spacer construction
1. Smooth, matte finish guaranteed against blistering and bubbling.
2. Thermoset silicone foam matrix.
3. Proprietary multi-layer vapor barrier.
4. Structural adhesive combines with perimeter edge sealant for dual seal performance and durability

Supreme Windows manufactures all Sealed Units for Windows and Doors with Super Spacer's Warm Edge Technology.

“Warm Edge” refers to the thermal conductivity of the spacer used to separate the lites of an insulating glass unit. If the spacer material is less conductive than conventional aluminum, it is
called warm edge.

TemperedTempered Glass

Tempered safety glass is mainly used in Door Glass Inserts for safety and security. When a piece of glass gets tempered using a process that heats, then quickly cools, it gets five to 10 times stronger than untempered glass.

Tempered Glass also comes with Low-E option to increase energy efficiency.


DW LAMILaminated Glass [Clear or White]

Laminated Glass is a piece of sandwiched glass with a thin layer of clear flexible plastic film called PVB (polyvinyl butyral). The plastic film holds the glass in place when the glass breaks, helping to lessen injuries from flying glass. The film also can stretch, yet the glass still sticks to it. It is also quite difficult to penetrate laminated safety glass, compared to normal window pane glass.



GPW (Georgian Polished Wire) glass is made of two pieces of glass glued together on each side of polished wire mat.
