Everything You Need to Know About Window Ratings in South Carolina
When it comes to choosing the right windows for your home in South Carolina, it’s important to understand the different window ratings and what they mean for your energy efficiency and comfort. Here are some of the most important window ratings to consider:
U-factor
The U-factor measures the amount of heat that escapes through a window. The lower the U-factor, the more energy-efficient the window is at keeping heat inside your home during the winter months. In South Carolina, a U-factor of 0.3 or lower is recommended for optimal energy efficiency.
Solar heat gain coefficient (SHGC)
The SHGC measures how much solar radiation enters through a window. The lower the SHGC, the less heat is gained through the window during the summer months. In South Carolina, a SHGC of 0.4 or lower is recommended for optimal energy efficiency.
Visible transmittance (VT)
The VT measures how much light passes through a window. The higher the VT, the more natural light enters your home. In South Carolina, a VT of 0.4 or higher is recommended for optimal natural lighting.
Air leakage rating
The air leakage rating measures how much air passes through the window. The lower the air leakage rating, the more energy-efficient the window is at preventing drafts and air leaks. In South Carolina, an air leakage rating of 0.3 or lower is recommended for optimal energy efficiency.
Design pressure (DP) rating
The DP rating measures the window’s ability to withstand wind and rain pressure. In South Carolina, the minimum DP rating required by code is 50. However, OKNA Windows, exclusively offered by Contract Exteriors, have a DP rating of 60 for their 800 series windows, making them an ideal choice for homeowners in hurricane-prone areas.
Energy Star certification
Energy Star certification is a program by the Environmental Protection Agency that recognizes energy-efficient products. Windows that are Energy Star certified meet strict energy efficiency guidelines and can save homeowners up to 15% on their energy bills.
When it comes to choosing the right windows for your home in South Carolina, OKNA Windows, exclusively offered by Contract Exteriors, are the perfect choice for maximizing your energy savings and comfort.

In fact, OKNA Windows have an energy efficiency rating that is 300% better than the average competitor’s window. The low-E glass is baked into the window, rather than being applied as a film, which provides superior clarity and energy efficiency. The spacer technology used in OKNA Windows is made from space shuttle material, which eliminates the use of metal and prevents heat transfer and seal failures.

Outstanding Reviews
Brooks was my contractor on the project. He was awesome! He was there with me every step of the way! Eugenia was very helpful in the office and assisted me in getting the HOA approval. Jason explained the warranty process and even brought me a cake!
Everyone we came in contact with was very cooperative and easy to work with. It was a pleasant experience from the first online chat. They listened to us and helped solve any issues we were concerned about
Wow, this company goes above and beyond. From the very first reach out to the very last interaction once the job was completed. Everything was done first class. The quality of work, the constant communication and level of service was like nothing I’ve ever experienced with any contractor. I priced out a couple different contractors compared to contractor exteriors and I will tell you I would have paid more just to have this experience with them. I had Jonathan as my project manager and he was exceptional.
Very happy with our new Timbetech front porch deck and steps with AZEK facia and risers. Everyone at CE was responsive and very professional explaining every step in detail! We have several homeowners in our community who have already asked for contact info info. Jonathan is a very good project manager and ensured we were satisfied with the quality, cleanliness, and appearance of our new front porch! Thank you!
In choosing a company to replace our deck, we researched and decided to use Contract Exteriors. We definitely made the right choice. We are very pleased with the results. Special thanks to Brooks, our Project Manager, who kept us updated and informed everyday.
Contract Exteriors did a great job for me. The entire group was very responsive, and my deck project turned out fantastic. My project, as all projects, had some surprises that were handled professionally and promptly. Randy, Brooks, and the office staff were great throughout the process. They proactively kept me informed on the status of the project. I never had to call twice to get a question answered or ask for an accommodation.
We couldn't be happier with contract exteriors and the job they did. Our beach house looks brand new with the new Hardie board and white trim. EVERYONE was friendly, well mannered, professional, and was always ready to answer any questions that we had. Miguel and his crew did an excellent job. Brooks the project manager was wonderful, and also Chad who helped us from the very beginning, also the girls in the office. We would not hesitate to use them again.
This company did an amazing job on my siding project. From start to finish they were very professional, helpful, and on time. Eugenia clearly communicated the whole process to me before they even started the project and Brooks was always available to answer my questions. He even came and ensured the cleanup was perfect and finished up the exterior lighting. Even after the project was finished this company ensured communicated to ensure everything was perfect. Super pleased. Thank you!
Everything about this group was extremely professional. Renovations can be challenging but they carefully made sure that their products and our original structures fit together seamlessly. We are truly looking forward to our new elegant deck that will be essentially maintenance free for many, many years. We will definitely use this company for future projects.
Matt Kuzdrall made our whole experience of purchasing two new roofs for our buildings at the Children's Recovery Center so easy. Matt was professional and had all the answers to any questions we had. He has followed up since our new roofs have been installed to make sure everything is still great. Matt is awesome and I would recommend him to anyone I know looking for a new roof.
