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.


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.

Patterns include: Standard Rectangular, Rectangular 1-High, Standard Rectangle Cottage 1-High, Prairie 6-Lite, and Prairie 9-Lite.
