Product Range of Leinwandbau
Leinwandbau covers the visual side of a home cinema completely, from the projection surface to the projector. The product range is oriented toward living room use and includes both ready-made products and components for custom-built solutions.
Screens
The core consists of fixed-frame screens in specialized designs. CLR, ALR, and Fresnel screens are designed to reject ambient light and maintain image contrast even in rooms that are not darkened. These screens are specifically tailored to ultra-short-throw projectors and are available in sizes from 80 to 130 inches. In addition, Leinwandbau offers floor-rising screens that extend upwards from a casing, as well as ceiling-recessed screens, both available in electric versions.
Screen Fabrics and DIY
For DIY projects, Leinwandbau offers screen fabrics in various sizes and specifications that can be mounted onto a custom-built or existing frame. This allows for dimensions to be realized for which no finished screen is available.
Projectors and Sets
Regarding hardware, Leinwandbau carries ultra-short-throw projectors and laser TV devices, which generate a large image from a short distance to the wall, thereby eliminating the need for ceiling mounting. Furthermore, the shop creates bundles consisting of a projector and a matching screen so that the compatibility between the device and the projection surface is already ensured.
Services of Leinwandbau
In addition to retail, Leinwandbau manufactures a portion of its screen range itself, allowing it to address requirements that cannot be met by standard products. Consultation on the selection of screens and projectors is provided by phone, WhatsApp, and email.
Delivery is carried out via shipping. On-site assembly or installation is not part of the service scope; the products are intended for self-assembly. As consumer protection features, the shop cites buyer protection through Trusted Shops as well as membership in the Händlerbund and the FairCommerce initiative.
Differentiation of Leinwandbau
The name "Leinwandbau" (Screen Construction) suggests a craft or installation business that builds and installs screens on-site. This is not the case. Leinwandbau is an online shop that ships home cinema technology and manufactures part of its screen range in-house. On-site assembly or installation for the customer is not offered; the term "Bau" refers to the home cinema project and the potential for DIY assembly by the customer.
Furthermore, Leinwandbau is not a pure manufacturer. In addition to self-manufactured screen products, projectors and laser TV devices from other manufacturers are sold. Finally, it is important to distinguish the brand "Leinwandbau" from the owner: the operator and contractual partner is the sole proprietorship of Michael Gradenegger; there is no limited liability company (GmbH).
