Wincore® Windows

One look, and you'll see—Windows Right For You!

As a proud homeowner, choosing the right windows and doors can be a daunting task. While some may say that “a window is a window is a window”, there are many manufacturers and many different choices for styles and options. But once you compare products and prices, we think you’ll agree that our energy-efficient windows are the right choice!

You expect a lot from a window manufacturer. That's why we do, too.

At Rhynehart Roofing, Inc. we had our valued customer in mind when we chose to install Wincore® windows and doors. For retrofit (remodeling) applications, nobody can top Wincore’s® innovation and their attention to detail. In fact, with multiple styles and options to choose from, you’ll find those innovative details and unmistakable quality craftsmanship in every piece of vinyl and every piece of glass. Our frames are contoured to replicate the traditional appearance of wood. Low E glass coupled with warm-edge technology ensures state-of-the-art modern performance and energy efficiency. After all, our customers wouldn’t settle for anything less. So, why would we?

Some of our window features include:

We also offer laminate, tempered, triple-pane, tinted glass, etc. For more information, call our office and schedule a free price quote today at 806-622-0090. Our sales staff will give you an honest proposal without the sales hype.

Keep your home and your wallet more comfortable year round.

With energy costs rising every day, the energy efficiency of a product is very important. Especially when it comes to windows and doors in your home. Drafty windows and doors can cause home energy costs to skyrocket. On the other hand, high-quality, energy-efficient windows and doors can help lower your energy costs day in and day out. Which helps you to spend less and save more all year long.

An efficient lesson on energy efficiency.

When you begin to consider the energy performance of a window or door, there are some terms used in our industry that you may not be familiar with. To help you better understand how the energy performance of a window or door is evaluated, we have outlined a few key measurement factors.

U-values & R-values

Rhynehart Roofing

Also known as the U-factor, the U-value measures how much heat loss or gain can be transferred through a window or door. The lower the U-value, the greater the product’s resistance to heat flow and the better its insulating value. U-value measurements generally fall between 0.20 and 1.20. For windows and doors, a low U-Value means less heat is able to penetrate your home during warmer months AND less heat is able to escape during colder months. The inverse (one divided by) the U-value is the R-value. The R-value measures the ability of a window or door to resist heat transfer. The higher the R-value, the greater resistance the window or door has to heat gain or loss. During warmer months, a high R-value means more unwanted heat from the sun is kept out, and in colder months, a high R-value means heated air stays inside where it belongs. Low E glass can have a positive effect on both U- and R-values.

Solar Heat Gain Coefficient (SHGC)

Quite simply, the SHGC value indicates how much direct sunlight and absorbed heat that can enter your home through your windows or doors. Sometimes referred to as a shading coefficient and usually expressed as a value between 0 and 0.87, a lower SHGC value is preferred. Just like U- and R-values, Low E glass will increase your window or door’s performance against solar heat gain.

When it comes to energy performance, sometimes our product designers get carried away. And for that, we owe them a great big thank-you.

Many factors contribute to a window or door’s overall energy efficiency. The product design, the style and size of the product and the type of glass used are all variables that can affect how energy efficient a window or door truly is. At Wincore®, we’re proud to know that our windows and doors represent some of the best thinking in the industry. Especially when it comes to energy efficiency. To give you a better idea of the efficiency features we design into our products, key components have been outlined below.

Low Emissivity Glass (Low E Glass)

Low E glass is glass that has thin, transparent layers of metal oxide applied to the surface. This coating allows light to pass through, while reflecting heat rays and harmful ultraviolet rays from the sun. Because the Low E coating helps to control the heat transfer through a window or door, it lowers U-value ratings and increases R-value ratings. Having windows and doors with Low E glass helps to keep your home more comfortable year round by helping to keep cool, air-conditioned air inside during warmer months and heated air inside during colder months.

Argon Gas

Most windows and sliding doors manufactured today feature dual-paned glass. That means there are actually two pieces of glass, separated by a spacer for uniformity, inside each sash of the window or panel of the sliding door. The spacer between the panes is sealed to each piece of glass, thereby creating an air space between the two. Temperature fluctuations cause air molecules to move around and transfer heat from one pane of glass to the other. This is known as convection and can result in heat gain in an air-conditioned room in your home, or heat loss in a heated room in your home. To minimize convection, Argon gas can be used to replace the air inside the insulated glass unit. Argon is a colorless, odorless, non-toxic gas found in the atmosphere. Argon’s molecular structure makes it more dense than air, causing it not to be affected as much by temperature fluctuations. When Argon is used to fill the insulating glass unit instead of air, it helps to reduce convection rates and thereby improves the efficiency of your window or door.

Chambered Vinyl Profiles

Rhynehart Roofing

Adding to the insulating performance of the window and door are honeycombed chambers inside the vinyl profiles. The chambers make the vinyl profiles stronger – not allowing the profile to sag or lose shape over time. But more importantly, because these chambers are small and airtight, they act as tiny pockets of insulation around the window or door, thereby increasing the unit’s overall efficiency.

Intercept® Spacer System

The uniquely designed U-channel spacer system adds to energy performance by helping to reduce temperature transference between the two panes of glass inside the insulating glass unit. With conventional box spacers, temperature transference can occur through a direct path across the top of the spacer. This is known as conduction. Because the U-channel design eliminates this direct path and forces the transfer current down and around the spacer, the current is weakened because of the additional distance it has to travel.

1/2'' Glass Penetration

To keep the edges of the glass warmer (where conduction currents originate), the insulating glass unit is set 1/2” deep into the vinyl of the sash. By keeping the edge of the unit warmer and better insulated against temperature fluctuations, it improves the the efficiency of the unit.



When it comes to energy efficiency, our star is shining brighter than ever.

To save money year after year on heating and cooling costs, make sure your windows and doors areRhynehart Roofing Energy Star® qualified. Energy Star® is a program run by the United States Department of Energy and Environmental Protection Agency, and is designed to help individuals and businesses protect the environment through superior energy efficiency. The Energy Star® label can be affixed only to windows and doors that meet specific U-value and shading coefficient ratings for one or more regions of the country. These ratings are achieved through independent testing done to NFRC (National Fenestration Ratings Council) standards. The ratings that a specific window or door achieves will vary due to the type of glass used, the window or door style and the overall product design. Wincore is proud to be an Energy Star® partner, signifying that our products can be ordered to meet Energy Star® guidelines.
