Whether we’re installing sliding doors or French doors on your patio, we make sure you receive the most energy-efficient doors possible. As a partner of ENERGY STAR® since 1999, Renewal by Andersen® of Kansas City builds only energy-efficient doors that have passed the ENERGY STAR criteria. Find out what makes our door energy-efficient by learning about their anatomy.
Our patio doors are made of laminated veneer lumber and constructed under extreme heat to make them resistant against cracking and warping, requiring little to no maintenance or repainting to keep them in pristine condition. With an added waterproof coating on the core material, every energy-efficient door is resistant against extreme weather and moisture.
Multiple Pane Glass
Another reason our doors are energy-efficient is we use multiple glass panels to prevent heat transfer. Since your French doors are exposed to extreme heat, having two glass panels helps stop heat from passing through your door. By using an argon gas blend in our Low-E4® glass, heat and harmful UV rays are reflected back, keeping your home cool and comfortable. We also provide other High-Performance™ Low-E4 glass options which are better suited for warmer and colder climates, like the SmartSun™ and PassiveSun® glass.
Old doors tend to have worn-out seals, which let warm air in and increases your home’s utility bill. But by having airtight seals on your energy-efficient door, you can prevent not only warm air but also rain and snowmelt from seeping through. For added weather tightness and security, our French doors also have a five-point locking system.
