LINVISIBILE® is an Italian brand founded in 1994 out from the experience of Portarredo Srl, a company that manufactures tailor-made doors and unique interior design solutions, such as room dividers, boiserie, and skirting systems. Our exclusive patented invisible technology eliminates posts, frames, exposed hinges and offers maximum versatility and customization. The result is a flush with wall design door which blends perfectly with the surrounding environment creating a distinctive perception of a hidden door.
More than meets the eye
Behind our work, there’s a hidden Italian story of exclusive design experience. The precise technical know-how is masked by the apparent simplicity of the flush with the wall door that, combined with a maximum level of customization, allows us to fulfill the most demanding aesthetical desires and functional expectations.
The excellent construction capacity of the company results from a long experience of research and accurate controls. The perfect planarity is one of our distinctive elements that, along with the customization, allow the door to adapt to any interior décor style in seamless continuity with the wall.
The history of a local craftmanship tradition
Born in the Emilia Romagna region, along the border of the provinces of Ferrara, Bologna, and Ravenna, LINVISIBILE® is the natural heir of a know-how that has evolved over more than 2.000 years of history. We drew sustenance from the roots of this territory, so rich in creativity, and found inspiration in hiding and masking locks and openings in the walls. Our products are the technological evolution of an old concept: “secret doors”. Hidden doors that exist in perfect continuity with their setting and that were used throughout history by the ruling Estense family of Ferrara to conceal secret passages from view.
Our project is the result of a lucky ‘hunch’ back in 1994 when, after listening to building site demands raised by different architects, the company transformed an artisanal carpentry system into an industrial process guaranteed over time. With this premise, we continuously work in the spirit of constant evolution looking at the future.
Care of human and environmental resources
At LINVISIBILE®, we investigate the future without forgetting about the past. This is why we are fully committed to the protection of our resources, either human or environmental, without ever compromising the quality of our products and processes. We are constantly innovating in every step of our value chain to maintain the highest manufacturing standards and promote sustainable practices.
Under this premise, we rely on a supply network composed of small and medium-sized local excellence, all based within 100 km from our production site. We are a certified company ISO 9001 and all our products comply with UNI EN 316, UNI EN 952, UNI 7961 standards. LINVISIBILE® also undertook the path to verify its doors and interior design solutions conformity, and with some number of credits determined by qualified technicians, can help buildings achieve the LEED® standards.
Located in one of Milan’s most important design districts, the showroom hosts a wide range of the latest brand products.
