Silex is Nav-System’s division manufacturing PUR and PIR sandwich panels for thermal insulation. The history of the company starts in 1962 when the founder Mr. Renzo Navarra began to produce industrial insulations with rice hulls. An innovative plant for the continuous production of PUR and PIR sandwich panels is Silex flagship, at the forefront in Europe for extrusion methods, attention to the details, cooling of the panels and packaging. Quality, design and innovation are the distinguishing marks of Silex PUR and PIR sandwich panels, thanks to a group of people who share the same passion, commitment and out-of-the-box view while carrying out their work. Custom care and confidence in the future are the same as in the 1962.
Silex has a qualified Laboratory of Research accredited by MIUR (Ministry of Instruction, University and Research) and its panels are a benchmark in the field of thermal industrial insulation and guarantee long-lasting performances over time. Silex PUR and PIR sandwich panels were the first ones to be certified Bs1,d0 according to the EN 13501 standard are still in between a selected group of manufacturers able to achieve so.
Silex is specified by European consultants to the cold industry (food and beverage production, cold storages and transport, blast freezer factories, atmosphere controlled storages, etc.) which appreciate their air-tight connection able to guarantee a sealed environment and no loss of temperature. Silex PUR and PIR sandwich panels for the cold industry can be produced to a max of 260 mm thick equivalent to an R value of 12,5. They are the ideal solutions for those chillers (positive temperature) and freezers (medium and low negative temperature) where condensation and therefore frost, optimal performance of the cooling system and therefore power savings, as well as long durability together with an easy installation thanks to a dry-fitting of the labyrinth connection in between panels is required. The entire range of PUR and PIR sandwich panels can be manufactured with specific high-quality coatings like triple-layer PVDF, high-density polyester as well as bacteria-free and easy-to-clean solutions.
a special sandwich panel with a double tongue-and-groove connection which allows the laying of an approved silicon in the groove to guarantee a tight vapour barrier, indispensable feature in the realization of temperature controlled environments.
the benchmark in the cold industry and an unrivalled panel with a dry-fit double labyrinth where the polyurethane foam is calibrated to perfectly seal the connection preventing any loss of temperature.
a concealed fixing wall sandwich panel ideal when the architectural requirements for an aesthetical façade meet the technical request for thermal insulation, acoustic performance and fire safety. Available in Corten® steel.
the most complete yet economical solution for wall cladding, with a custom finish in terms of colours, texture and steel skin finish.
not just “on papers” basing on lab tests or calculations, but tested and appreciated in hundreds of cold rooms realizations worldwide.
where panels, packaging as well as colour-matching metal flashings can be manufactured in accordance with the client needs and for no minimum order quantity.
which produces from its photovoltaic system on the factory roofing all the power needed to run production machines and office equipment. A company that from 2017 is assessed EPD (Environmental Product Declaration) and oriented to a supply-chain with the lowest possible environmental footprint.
