All Types of Windows

Windows with  a nice view outside

We understand the importance windows have in a home or business. Not only do they let natural light through, but they can help regulate temperatures and provide structural support to the building. This is why we offer a range of window styles and materials for you to choose from.


  • Aluminum
  • Vinyl
  • Wood
  • Energy efficient


Aluminum windows offer a timeliness appeal with their slim profile and narrow sight lines. They fit well in the modern home and are durable and long-lasting while requiring minimal maintenance.


Vinyl windows can support the integrity of your window and offer higher-energy efficiency for your home. These types of windows are affordable, low maintenance, and come in many styles.


Wood is one of the most customizable materials when it comes to windows. From the type of wood to its style, wood can look great in traditional, historic, and modern buildings. It adds a natural beauty wherever it is and is also a great insulator.

Glass Suited to Your Needs

In addition to offering a variety of window frames, we also offer many types of glass. From clear float glass to insulated glass, we’ve got you covered.

Clear Float Glass Clear float glass is transparent and has a smooth, glossy surface. It is easy to clean and is a great way to showcase products.
Low-Iron Float Glass Also called extra-clear glass, low-iron float glass is actually more transparent than clear float glass. It is great for applications where you need to make detailed objects highly visible.
Satin Glass Satin glass is chemically treated to give it a misty-looking finish. When you don’t want full transparency, this glass helps create a sense of privacy while still letting light through.
Tinted Glass Tinted glass is treated to have a bronze, green, blue or grey tint to it. This reduces the transmission of UV light, thus reducing heat gain
Patterned Glass Also known as decorative glass, patterned glass is treated to create a pattern or design. It helps create visual interest and can add privacy in your home or in a commercial setting.
Low-E Glass Low-E glass is coated so that it minimizes UV light without reducing the visible light transmitted.
Insulated Glass Insulated glass is designed to well, insulate your home. It consists of multiple pieces of glass separated by spaces and will help keep your home warmer in winter and cooler in the summer.

Clear Float Glass or Low-Iron Float Glass?

Deciding between clear float glass and low-iron float glass can be tricky. The main difference between the two types is that clear float glass has higher levels of iron, producing a greenish tent. This is a preferred glass for custom back-painted glass and color matching. Low-iron gloat glass is a better choice for high-level displays, frameless glass walls and anytime where you need to showcase merchandise without a greenish tint.
