Glass Coatings

Our experts will walk you through energy efficient glass options to find the right selection for your home and the best windows for your climate. Choose from four glass coatings, plus decorative glass options, and specialty glass choices.

Low E-1

Primarily used in colder climates, Low E1 allows more heat in to warm a room while blocking heat loss.

Low E-2

Low E2 offers year-round performance in moderate climates. It will help retain heat in your home during the winter and keep heat out during the summer.

Low E-3

Low E3 rejects solar heat while letting light in, resulting in increased performance in climates with intense sun exposure.

Low E-3/ERS

Low E3/ERS provides maximum efficiency year-round in all conditions.

Specialty Glass

We offer specialty glass to best suit the needs of your home. You can choose tempered glass, laminated glass, and STC/OITC glass for specific windows and rooms.

Tempered Glass

Tempered glass increases glass strength to help prevent breakage. Tempered glass is ideal for windows close to the floor or located in high-traffic areas.

Laminated Glass

Even more durable than tempered glass, laminated glass is often referred to as impact resistant or safety glass due to its vinyl inter layer that tends to remain in place when shattered.

STC/OITC Glass

Sound Transmission Class and Outdoor-Indoor Transmission Class glass has increased pane thickness on the room side and works in areas where exterior noise is a concern.

Divided Lites

We offer various divided lite patterns so you can replicate the look of your original windows and doors. Or, add new architectural interest to your home. Choose from Simulated Divided Lites for classic appeal or Grilles-Between-the-Glass for easy cleaning.

Selected: Grilles Between the Glass

Maintenance

Since special shape windows are direct glaze windows, there are no maintenance requirements for hardware or weatherstripping. You can clean the glass occasionally, and maintain the interior and exterior surfaces on the same schedule as your other windows.
