At ON Star Windows & Doors, we do more than just installing windows and doors. We strive to improve the energy efficiency of your home. We stay up-to-date with the latest technological developments to provide you the most durable products. The replacement windows we install are not only aesthetically pleasing but also energy-efficient. If your windows have become old, drafty, hard to operate, they are basically wasting energy. Old and damaged windows are unsafe, as well as incapable of preventing air leakage that negatively impacts your home’s energy efficiency. Just a decade ago, windows had no energy performance criteria. But over the years, the government implemented Star Ratings and Energy Performance Requirements for all new homes. Once we install energy-efficient windows in your home, you’ll notice a considerable difference. Our laboratory tested and certified windows are proven to enhance your comfort, as well as reduce those expensive heating and cooling costs while increasing the value of your home. Installing the most advanced triple and Double Glazed Windows is the best solution to lower your utility bills.
Whether you live in a villa or apartment, we have a product to enhance your residence. Our superior quality, energy-efficient replacement windows come in a variety of styles and sizes to suit all of your needs. At ON Star, you can find window styles such as awning, casement, sliding, bay, and bow, single-hung, double-hung, and more to suit your individual requirements. Our experts can also guide you about the best complimentary joinery to make your home look incredible while reducing noise and condensation. We make sure to use our expertise to turn your ideas into reality.
