The Therma Tech 3400 (previously marketed as Therma Tech) is a fantastic addition to Hörmann’s Therma Tech™ line of insulated raised steel panel doors, known for their quality, value, and stylish designs. With six wood grain textured panel options to choose from, including Short Raised, Long Raised, Shaker, Country Panel, Cottage Panel, and Flush, you can effortlessly find the perfect match for your home’s aesthetics. The door’s 1-1/2″ thick EPS core ensures exceptional insulation with an R-value of 7.4, making it ideal for colder climates, where it provides the best long-term insulating value.
To enhance its durability and energy efficiency, the Therma Tech 3400 features a reliable Tongue and Groove joint between sections with a Thermal Break, while the U-shape loop type vinyl bottom weather seal keeps out the elements effectively. The doors are also pre-painted with a baked-on polyester enamel finish in five standard colors: Bright White, Almond, Sandstone, Black, and Brown. For a touch of elegance, you can opt for the Dark or Medium wood grain finish, available on certain panel styles. With Hörmann’s Therma Tech 3400, you can elevate your home’s appearance and energy efficiency, all in one fantastic package.
