If you have old, single-pane windows in your home, replacing them with Energy-efficient windows can significantly reduce your utility bills. Energy-efficient windows also help to keep your home quieter and more comfortable.
The muggiest period of the year lasts 4.7 months and averages 27.0 days of uncomfortable humidity levels. Cayce also gets a fair amount of precipitation, 109 days a year on average.
U-factor
The U-factor of a window is one of the most important energy-efficient features to look for when buying new replacement windows. It measures how well the window prevents heat from escaping your home, which can reduce your utility bills and improve comfort. The U-factor is a rating system devised by the National Fenestration Rating Council (NFRC).
It takes into account the performance of the glazing, window frame and spacer. It is also an important indicator of how well the window can resist unwanted solar heat gain. Choosing a high-performance window with a low U-factor will maximize your energy savings and comfort. Contract Exteriors offers OKNA windows, which feature innovative spacer technology and a low U-factor.
SHGC
Solar heat gain is an important consideration for homeowners, particularly those living in mixed climates. Windows with a lower SHGC allow less solar heat to pass through, keeping the home warmer during the winter and reducing cooling costs. To achieve a low SHGC, there are several options, including outside shading (pergolas, Venetian blinds, bushes and trees), varying window orientation and using low-e glass with a reflective coating.
The SHGC rating is found on NFRC labels, along with the U-factor and visible transmittance. It is also shown as a number between 1 and 0. A lower number means more solar heat is blocked. This metric is especially useful in hotter climates, where air conditioning is necessary.
VT
There are many signs that it’s time to replace your windows, including high utility bills, drafts coming in from the windows, condensation between window panes, and fading of the color or deterioration of the frame. Replacement windows offer a solution to all of these problems and can help you save money on energy bills.
Look for Energy Star-qualified windows with low U-factors and high VT ratings for maximum energy savings. Also consider glass coatings that reflect infrared heat without blocking visible light. This will improve insulation performance and allow more daylight into your living spaces. These upgrades can significantly reduce your utility bills and improve your home’s comfort.
Air leakage rating
The air leakage rating of a window determines how much air can make its way through the frame, which is essential for insulating your home. A low number indicates that the window is better insulated, and will save you energy.
The VT and SHGC ratings are not the only factors to consider when choosing windows. You should also take into account the DP rating, which measures the window’s ability to resist condensation build-up and wind resistance.
The NFRC sets objective energy-performance ratings to help consumers compare products and choose the best ones for their homes. These ratings are used by ENERGY STAR to qualify windows, doors, and skylights.
DP rating
The DP rating is a measure of how well the window resists air leakage. This enables you to determine how much energy the window will save. In addition, a higher DP rating means that the window is more resistant to condensation.
You can find these ratings on the NFRC label. They are also available online, and they can help you compare different windows. The DP rating is a crucial indicator of the energy efficiency of a new window or door.
OKNA Windows from Contract Exteriors offer some of the best energy-efficient windows on the market, with high DP ratings and low-E glass that is baked into the frame. They are also made of durable materials that won’t rot or rust.
Energy Star certification
The ENERGY STAR label helps homebuilders and renovators find windows that meet strict energy efficiency guidelines. They can also qualify for utility rebates and tax credits.
ENERGY STAR certified windows, doors and skylights are independently tested and verified to meet the specific performance requirements for their climate zones. These products meet strict energy efficiency guidelines set by the EPA, and are also compliant with the latest International Energy Conservation Code (IECC).
ENERGY STAR certified windows offer more comfort and savings than ever before. They are available in a wide range of framing materials and can be combined to maximize performance. The best frames for ENERGY STAR certified windows include aluminum and vinyl, which are durable, low maintenance and easy to work with.
