The Full View on THV Windows
Siding-1 Windows-1 Exteriors continues its commitment to providing our Chicagoland customers the most innovative products available. And there are many. Our partnership with THV allows us to offer these state-of-the-art windows which provide as much in energy saving value as they do in design.
THV uses only the best quality materials for hassle-free performance. THV Compozit Windows are made from Expanded Polymer Composites (EPC) produced in the presence of physical/chemical blowing agents, resins and modifiers, resulting in foaming materials with closed cells to enhance and improve impact resistance, weathering characteristics and superior thermal performance. EPC withstands moisture and rot, creating a window 400% stronger than ordinary vinyl. Click here to get intimate with the materials that make these windows perform.
Superior manufacturing methods ensure superior strength. Most windows are held together with staples or screws and caulk that can loosen or weaken over time. But THV sashes and frames are pinch fusion welded — an advanced technique that permanently fuses all four sides together into a single weather-tight unit, guaranteed to stay strong and square for 50 years. Advanced technology is incorporated into every window style, which translates into exceptional energy-efficiency for your home, without compromising durability. Learn about these durability features in greater detail here.
The next step is ensuring an installation process that brings out the best in each window. Combing expertise with service, Siding-1 ensures quality all the way to your view. A free estimate is the easiest way to start your energy savings with style: 800-929-9275.
