Henselstone Window and Door Systems Inc. imports, distributes, installs and services custom-made fenestration products from Germany, such as tilt-and-turn windows, out-swing windows, lift-and-slide doors, in-swing/out-swing doors, fixed glazing, storefront, pivot windows and doors, arched, oval, rounded and peaked shapes. The products are specially designed for hurricane resistance, energy efficiency, noise pollution reduction, and security. All products are tested in the United States according to the international building code and American standards for ratings, specifications, and legal requirements. The catalog includes a low maintenance PVC product line, a hardwood product line, and a metal clad product line. The PVC products are a revolutionary design that makes it virtually indistinguishable from real wood, including finger joined miters and hundreds of coloring and stain options while still being virtually maintenance free. The wood products compare more to furniture than windows. Materials include hardwoods such as mahogany, oak, and meranti. The metal clad products are hardwood windows and doors with a extruded metal exterior that can be aluminum, stainless steel, cooper, or bronze.
