Fibrotek – Under-roof thermal insulation system

Fibrotek PLUS

Underroof Thermal Insulation System with Double Stiffener

Fibrotek PLUS is the latest thermal insulation panel developed by Fibrotubi, featuring a double stiffener design with an extended pitch. Fibrotek PLUS with double stiffener allows for fewer fastenings during installation and reduces material consumption, resulting in significant cost savings. Fibrotek Plus halves installation time, ensuring a roof is built very quickly, and is particularly suitable for laying slate tiles and short/reduced pitch coverings from 380 to 710 mm.
The installation system always starts with a panel with a shorter pitch of 280 mm with single stiffener, followed by the other Plus panels with double stiffener, with the pitch determined by the covering layer to be installed, such as tiles, roof shingles, etc.

Like the entire Fibrotek range, the product complies with the Minimum Environmental Criteria (CAM) regarding the percentage of recycled content in insulation materials and is therefore eligible for the related tax incentives.

Advantages

Thermal Insulation

The insulating core of FibroTek is made of high-density rigid polyurethane foam, currently the material with the best thermal conductivity for a given thickness.

Ventilated

Thanks to the special design of the metal stiffener, which creates a 4 cm ventilated air chamber, an excellent and evenly distributed airflow is ensured beneath the entire roofing. This results in: – improved indoor comfort, thanks to the removal of excess heat in summer and condensation in winter; – increased durability of the roof covering, by maintaining balanced temperature and humidity conditions between the underside and upper side of the roofing material.

Waterproof

The embossed aluminum foil covering the insulation layer not only protects the insulation from deterioration due to air exposure but also acts as a vapor barrier (on the lower side of the panel) and as protection against possible water infiltration from the roof covering, allowing water to flow down to the eaves. FibroTek thus serves as a secondary waterproof layer, in combination with the primary waterproofing provided by the roof covering above it. FibroTek riveste il ruolo di secondo manto impermeabilizzante; in abbinamento a quello primario dato dalla copertura sopra abbinata.

Resistant

When installed on a continuous support structure (such as a reinforced concrete layer or wooden decking), FibroTek panels create a fully walkable load-bearing surface. In the case of discontinuous supports (wooden or steel beams), it is necessary to walk by stepping on the metal battens, avoiding the joints between panels. The robust section of the metal batten has been specifically designed to adequately support not only pedestrian loads.

Quick and Cost-Effective

The installation of FibroTek panels is extremely fast, thanks to their interlocking tongue-and-groove profiling, which ensures precise and secure assembly, and to their light weight. The fixing of the roof covering is also simplified and safe, thanks to the wide support base on the metal batten. Moreover, FibroTek offers an economic advantage: by integrating multiple layers into a single panel, it significantly reduces installation time and overall costs compared to traditional roofing systems.

Applications

Roof layer installation

The Fibrotek system is compatible with Marseille, Portuguese and Roman tiles, as well as concrete tiles, slate sheets, and corrugated or ribbed panels made of fiberglass, fiber cement, or metal. The Aluzinc metal stiffener is engineered to adapt to different roofing materials and fastening methods: from traditional interlocking tile systems to self-tapping screws used for metal sheets, ensuring reliable support and ease of installation.
