Ondal

ONDAL is a “ground water” system that combines architecture, performance and durability, and is sold complete with all the necessary complementary works. The result of years of research, studies, experiments and checks, it is now the heritage of a small group of leading companies on the national market.

The main element that characterises it is the ONDAL tile, which is used, in the standard solution, alternated with Curved or Straight Secondary Elements and is characterised  by closed heads. These give it great stability and harmoniously define the intrados of (the roofing) by connecting it to the supporting beams and creating a profile without points of discontinuity. In addition, the sealing of the joints to the intrados, the colouring and all the necessary elements constitute an already widely tried and tested value that SICEP makes available to professionals and clients alike.

EFC ON ALUZINC SHEET

Thus composed, the system with an entirely concrete roof, with high aesthetic and formal value, ideal in terms of fire resistance (R120-R180) allows solutions with zenithal and/or shed lighting, combines a high insulating power, in compliance with the required energy performance, with a ventilated roof and combines the advantages of lightness and minimum footprint with design flexibility.

The Ondal tile

It is the main element of the construction system and is produced in two standard heights, H 70 for spans up to 25 metres and H 100 for spans up to 30 metres.

The benefits

HIGH STRUCTURAL PERFORMANCE

The Ondal tile is made of high-strength pre-compressed concrete obtained with constant electronic control systems. Reduced weight. Minimum structural footprint of the roofing. Spans up to 30 m.

HIGH AESTHETIC VALUE

The Ondal aerofoil with the curvilinear heads that connect to the secondary elements and head elements harmoniously defines the intrados of the roof

FIRE-RESISTANT

The all-concrete structure guarantees high R values (120-180) and easy smoke and heat evacuators installation

FLEXIBLE INTERIOR LIGHTING

Zenithal and/or shed systems ensure optimisation of lighting

HIGH ENERGY PERFORMANCE

The insulation passing on the extrados of the roof can be graduated so as to obtain a value of the overall transmittance of the roof increasing and/or complying with the indications of the Ministerial Decree of 26-06-2015 and subsequent amendments.

GROUND WATER

The system lends itself to being installed flat or on a slight slope to create the so-called “ground water”. The downpipes internal or external to the columns are made complete with any ancillary works

WATERPROOFING

Made with aluzinc or aluminium plates, it also allows ventilation of the roof and guarantees its durability over time. In addition, it allows easy installation of photovoltaic panels without limitations in compliance with the legal criteria

QUALITY

The optimisation of production processes makes it possible to monitor in real time the parameters determining the performance of processes and products in qualitative and quantitative terms.
