Maximize Your Home’s Comfort and Savings with Energy-Efficient Windows

August 28, 2023

When it comes to home improvement projects, replacing your windows may not be the first thing that comes to mind. However, upgrading to energy-efficient windows can provide numerous benefits for your home and your wallet. In South Carolina, where the weather can be hot and humid, energy-efficient windows are especially important for keeping your home comfortable year-round. 

At Contract Exteriors, we offer a wide range of energy-efficient windows, including vinyl windows and double-hung windows, but we’re most excited about our exclusive partnership with OKNA Windows. Here’s why:


High DP Rating

The building code in South Carolina requires windows to have a minimum DP50 rating, which measures a window’s ability to withstand pressure during severe weather events. While many competitors meet this standard, OKNA Windows surpass it with their DP60 rating, making them some of the most durable windows on the market. With the OKNA 800 series, you can be sure that your windows will withstand even the most extreme weather conditions, withstanding winds of up to 180 miles per hour.

Energy Efficiency

Energy-efficient windows can significantly reduce your energy bills, and OKNA Windows are some of the most energy-efficient windows on the market. They have an air infiltration rate that is 300% better than average competitors’ windows, meaning less air will leak in or out of your home. This not only reduces your energy bills but also increases the overall comfort of your home.

Low-E Glass

Low-E glass is a type of glass that has a special film baked in or placed over the window to reduce heat transfer and UV rays. Many companies use Low-E glass with a film applied, but OKNA Windows use Low-E glass that is baked in, making it more durable and long-lasting. This means your windows will maintain their energy efficiency and protect your home from UV rays for years to come.

Innovative Spacer Technology

When windows are put together, there is a gap between the panes that must be filled with a spacer. Most companies use metal spacers wrapped in material, but metal can conduct heat, which can lead to seal failures. OKNA Windows use a unique spacer made from space shuttle material that eliminates the need for metal, providing superior durability and energy efficiency.

Not only do OKNA Windows offer unparalleled durability and energy efficiency, but they also come in a variety of styles, including double-hung, casement, horizontal slider, and special-shaped windows. This means you can find the perfect windows to complement your home’s style and enhance its curb appeal.

At Contract Exteriors, we’re proud to be the only dealer in South Carolina that offers OKNA Windows. Our team of experts can guide you through the selection process and help you choose the best windows for your home. Whether you’re looking for vinyl windows, double-hung windows, or another type of window, we’ve got you covered.
