There are two basic types of glass for windows, "Regular" glass and Safety glass. However there are several construction options available to meet your specifications.

Performance options include:
• Double pane
• Triple pane
• Laminated (Safety)
• Tempered (Safety)
• Low Emisivity Coating (Low-E)
• Insulating Gas
• Foam Filled Frames

• Many other options available

There are also optional features such as:
• V-Groove Glass (decorative)
• Blinds between the glass (Energy Efficient)
• Muntins - Flat - Contour (decorative grids)

We meet your needs for energy efficiency, strength, and appearance.

Window Frame Corners

Other window companies use a lesser quality second-life vinyl, only offering a screwed-together frame (saves them on cost & time) which is weaker and allows cold air to blow through the frame. They usually fail within five years. Pardon the pun, but they're "cutting corners." They often buy "their" windows overseas and resell them to you.

Our highest quality, strongest, longest lasting, pure virgin cPVC window frames offer fully fusion welded corners for much better strength and performance against cracking, breaking, leaking and air infiltration for decades. As our corners are fusion heat welded instead of chemical bonding (VOC's), there is no risk of off-gassing of VOC's with our fusion heat welded corners. All of this combined together is why we are able to confidently offer a Best in the Industry 30 year warranty. We manufacture your windows to your specifications right here in the USA.

You would want a stronger, better performing and safer corner, wouldn't you?

The Purpose of Insulating Glass

Windows have been utilized for many centuries and everyone knows what a window is. Or do they? In it's simplest form, a window is an opening in a structure whose main purpose is to admit light from the outside. The problem here is that a simple opening not only admits light, it also provides a path for more undesirable elements such as rain, cold air or insects to enter the structure. Our early ancestors partially eliminated the problems of rain, cold air and insects by covering the window opening with a material such as oiled parchment or oiled skins. These materials permitted some light to enter the structure while at the same time keeping out the undesired elements. Covering a bare opening in this early fashion was a tremendous improvement but it still had some drawbacks. Even though light would pass through these windows, they were not clear enough to see through. Replacing the covering material with clear glass eventually solved this problem. A sheet or pane (also called a lite) of thin clear glass mounted in a frame, and placed in the side of a structure, remains the most common type of window in use today.

While the glass window is a tremendous improvement over earlier window types, it still has its drawbacks. Most significant is that glass itself is a conductor of heat/cold. This causes problems in areas of the country where temperatures vary below freezing. Not only does the glass allow heat to escape from an enclosure, as the glass temperature drops below the freezing point of water, the inside of the glass window collects moisture from the air in the room. The moisture can condense to a point where it fogs up the window, or even freezes, which limits visibility. In addition, the condensed moisture collects to a point where it runs down the glass and accumulates on the window frame (sash), eventually causing damage. These problems were somewhat eliminated by the invention of the "storm" window. A storm window is an additional piece of glass mounted in a frame and placed over the window. Essentially the result is that there a two pieces of glass separated by an air space. Air is a good insulator of heat/cold and the air space serves to slow down the passage of heat or cold from the inside to the outside or vice versa.

The last step in the evolutionary chain is the development of the insulating glass (IG) unit. Adding a storm window to an ordinary window provides many benefits but with some drawbacks. The storm window can never be sealed from the outside moisture, which allows heat transfer and fogging in between. Additionally, the storm windows must be installed or closed for the winter months and removed or opened in summer. Basically, an insulating glass unit consist of two lites of glass, separate by a spacer and hermetically sealed. The IG unit is mounted in a sash and frame, and the complete unit is what we call a window.

Many companies are more interested in cutting cost at the expense of quality, and where is the main place they cut their cost? The vinyl frame. They eliminate as much vinyl as they can get away with. The issue with this is, it results in a weaker, less energy efficient window frame that will fail in only a few short years. And they provide no integrated weather-stripping.

We produce a strong vinyl window frame that will withstand the test of time and weather to give you decades of trouble free operation and performance that is unparalleled in the industry. We make our vinyl window frames to solidly hold the weight of the glass, temperature, wind loads and user operation. We offer more chambers of dead air space to insulate against the cold and heat of the season. Our vinyl window frames also offer integrated weather-stripping in multiple locations on both the window frame and the window sash. Our vinyl window frames are designed to keep the heat out in the summer, and retain the heat that you pay for, inside of the home during the winter.

Compare the cross-sections of their window frame on the left, to our beefier frame on the right. You would want to trust your investment to a stronger, better engineered frame, wouldn't you?

Spacers separate the panes of glass in an insulating glass unit allowing for a better thermal break and provide an air space between the panes. Many companies use a thin metal spacer which conducts cold & heat from one pane of glass to the next. We use a "Warm Edge Spacer" which is made from an extruded thermoplastic compound to provide the best thermal break in the industry. It prevents the transfer of heat & cold from transmitting from one pane to the next. Many companies use a multi-piece spacer which allows for air leakage at the corners (seams) which allows cold air to pass through, our spacer is a one piece, seamless design to ensure a long seal life and superior performance.

When all of these well thought out designs and quality materials come together, we create the best, most durable, energy efficient insulating glass unit. It's construction begins with quality glass (often with a "Hard Coating" or "Low-E") , a Warm Edge Spacer and an insulating gas, such as Argon. A properly designed and constructed IGU (Insulating Glass Unit) will provide a superior R-Factor (saves money on energy cost in the winter), it will reduce Solar Heat Gain (saves money on energy cost in the summer), it will reduce sound transmission, it reduces UV transmission (helps to prevent fading of finishes inside the home), reduces the chance of condensation forming on the glass which can lead to wood rot and mold. And once you add Blinds Between the Glass, our IGU's are the absolute best window in the world. In the end, our IGU's will save you money, reduce maintenence and improve personal comfort inside of the home.
