Folien21 offers made-to-measure decorative and functional surfaces for kitchens, bathrooms, doors, and living spaces. The brand highlights its own manufacturing in Hagen, Germany, and focuses on products that combine practical protection with a choice of designs and straightforward installation. Its range includes kitchen and shower backsplashes made as self-adhesive film or rigid aluminium composite panels, as well as door films and privacy films for glass. Customers can choose from styles such as marble, stone, wood, concrete, nature, and other printed motifs.

Kitchen films are designed to fit varied surfaces and feature a wipeable, protective finish; the company describes them as heat- and splash-resistant. Kitchen panels offer a robust, stable alternative, with matt or glossy finishes and formats up to three metres for a seamless appearance. Shower backsplashes are custom-sized and presented as waterproof, easy-care solutions, available in film or panel form. Door films provide a way to refresh doors without replacing them, while privacy films offer light-through screening for shower glass.
