Linvisibile was created in 1994 out of the experience of Portarredo Srl, an Italian company founded in the early 80’s that specialises in manufacturing doors and locking systems featuring exclusive designs and materials.
Portarredo distinguished itself from the very beginning thanks to the fully developed technological value of its products, and succeeded in earning a name with its brand at the top of the market of windows and doors. Through close collaboration with architects and engineers, Portarredo has developed products that look into the future of home living, anticipating market trends and needs.
In the initial project, studies and researches were merged in order to propose personalised design configurations for architecture solutions aiming to satisfy demanding expectations, different tastes and a variety of lifestyles.
Linvisibile was born from this project, arising as the first-ever trademark in Italy to manufacture doors and locking systems totally flush to the wall. This exclusive and patented “invisible system” eliminates the need for doorposts, frames or exposed hinges, providing our doors with perfect smooth opening and motion.
This practical and innovative system found its inspiration in the objective of hiding and “masking” locks and openings in the walls; this is the fundamental concept of Linvisibile philosophy. In fact, Linvisibile system is the technological evolution of an old concept: dungeons. Doors that exist in perfect continuity with their setting, and were used throughout history to conceal from view, openings whose existence we shouldn’t be aware of.
Over the years, the evolution of taste and architecture demands has turned doors into a key feature of interior design. Under this premise, Linvisibile continuously works and finds inspiration from designers to deliver tailor-made interior design pieces with maximum versatility and personalisation.
In the spirit of constant evolution and looking into the future, Linvisibile has inevitably grown and expanded its horizons into the international scene. With this challenge in mind, Linvisibile has reinvented itself altogether…new image, services and product offer. The world of is in constant innovation, and so are we.
Linvisibile, More than meets the eye.
Behind our work there’s a hidden Italian story of experience exclusive design. The precise technical know-how is masked by the apparent simplicity of the flush-to-wall door that, combined with a maximum level of “customization”, allows fulfilling the most demanding aesthetical desires and functional expectations.
Research and development
Linvisibile considers quality and scrupulousness in the choice of materials and working processes, essential elements for carrying out its operations.
In the last years and against market trends, the activity of the internal R&D department has led a constant growth, developing ideas and innovations able to achieve the highest expectations and many times, forecasting them.
Thanks to significant investments in human resources first, and technology after, Linvisibile’s R&D department is continuously studying new solutions, materials and innovative ideas.
Linvisibile products grow through the designers’ ideas: new locks, movements without noise, integration with home automation, customized finishes, more advanced ‘flatness’ effect, etc. These are just some of the latest features resulting from semi-robotic technology that, besides increasing our production capacity, further develops the system perfection and tightness.
Thanks to the know-how gained in the field over the years and our great on-site experience, Linvisibile system is being continuously improved and perfected.

The LEED® standard (Leadership in Energy and Environmental Design®) is a construction standard based on certain fundamental principles such as the containment of the energy used (including the use of recycled and recyclable materials), the control of polluting sources (both during the construction phase, and in use of the property) and the commitment to maintain a comfortable environment for those who will have to reside.
The LEED® certification is issued to the building as a whole, not to the individual product. The final score of the building will depend in large part on the correct selection and use of compliant products. For architects, designers and clients it’s essential to know for sure what the market offers at the level of “Leed® Compliant” products. The future market will keep asking more for the use of products compliant to LEED® standards.
This is the fundamental reason why Linvisibile undertook, with determination, the path to verify its products conformity, and in doing it so, contribute to the LEED® certification of buildings. The analysis, carried out by qualified technicians, about the construction features, performance and on the used materials, determines the type and number of credits with which Linvisibile products contribute to achieving the LEED® standard.

The FSC® Certification, Forest Stewardship Council®, is the primary assurance mechanism on the origin of wood or paper.
It is an international certification system which ensures that the raw material used to make a wooden or paper product comes from forests managed in a responsible way, where environmental, social and economic standards are strictly met.
The demand, from consumers, for goods and services that respond to the requirements of “environmental quality” has grown exponentially. To the same extent, Linvisibile’s commitment and investment has increased, with great attention, the company has undertaken paths in favour of issues related to environmental sustainability.
In particular through the FSC® Certification, to ensure and demonstrate the proper use of forestry products and the maintenance of the principles to which the certification is based on with regard to the responsible management of forests and timber products, Linvisibile becomes part of the chain of custody which regulates the supply of the wood, becoming the guarantor towards its customers.
Upon request, all Linvisibile products can be realized according to the FSC® Certification criterion, which involves a responsible forest management.
