Iglù® is a market leading product that was created and patented for the realisation of sanitary spaces, ventilated cavities, under-floor cavities, ventilated floors and roofs during the construction and restructuring of civil and industrial buildings. This result of an ingenious idea dating back to 1993 considerably improved building methods. The innovative capacity of Iglù® has received numerous successes and recognitions on a national and international level, quickly confirming it as a product of excellence in the building world. The modular, plastic Iglù® formworks, placed side by side...

The problem for buildings: rising moisture The problem of rising moisture from the ground and its results on the integrity of the structures and the healthiness of the inner rooms has been well known since antique Rome. At those times, the under-floor cavities were created by raising the floor a few centimetres using amphoras or low walls. This created a cavity that was connected to the outside with ventilation inlets in order to guarantee ventilation (so-called ventilated wall cavity). This formed the basis for what is today commonly called a "sanitary space". The Roman technique has...

The final solution: Iglù® A ventilated under-floor cavity created with Iglù® represents an effective, quick and economic solution that makes it possible to send humidity and dangerous Radon gas to the atmosphere, which is beneficial to our health. The air cavity formed by the Iglù® modules must be connected to the outside with simple pipes. This creates a natural air flow that crosses the cavity and eliminates moisture and Radon gas (if present). The results of some ventilation tests (carried out on our behalf by the University of Brno - Czech Republic - available on request) indicate that...

Advantages • Possibility to implement, in a single solution, foundation beams and the slab with the help of the L-Plast and Beton Bridge accessories. • Reduction of manpower requirements by up to 80% in comparison to traditional systems. • Drastic reduction in the use of concrete and aggregates as the arch form permits maximum resistance with a minimum thickness. • Adaptable to non-standard spaces as the modules can be cut without underpinning. • Ease of positioning due to lightness and simple linking of the modules. • Simple adaptation to various perimeters. • Quick and immediate cutting...

Water collection tank Applications • Ventilated under-floor cavities for civil and industrial buildings that are being built new or reconstructed. • Urban infrastructure structures: squares, sidewalks, sports facilities. • Creation of an intermediate slab or roofing for cavities used for ventilation and the passage of systems. • Rooms used for humidity and temperature control: drying cells, cold rooms, greenhouses, storage rooms and cellars. • Underground pipes for the passage of utilities. Inspectionable cavities and pits. • By filling it in simply with expanded clay, it can be used to...

IGLCI' Hypothesis of ULS calculation based on Iglu® H 30 cm The table shows, starting from a uniformly distributed load's hypothesis, the minimum thickness of the slab, the type of reinforcement and the pressure on the ground, according to the type of lean concrete (using the IGLU'® H 30 cm). For the dimensioning of all different heights, please see the technical data sheets. * Accidental overloads in different environments as provided in Table 3.1.II NTC 2008 - Values of the workloads for the different categories of buildings.

Fig. 2 - Dry positioning sequence of the modules by row. 1 Position the first element to the upper left with respect to the work surface, making sure that the arrow is pointing up (Fig. 1). 2 Unite the elements in sequence, by horizontal row, proceeding from the left towards the right and from the top downwards (following the direction normally used for writing), as shown graphically on the crown of each unit (Fig. 2). 3 To unite the units in sequence, be careful to perfectly link the “male-female”...

IGLtl'Application example: cold rooms Iglu® has numerous advantages, for example ventilation and is more effective because it creates a single open space under the floor and the air can circulate in all directions. There are also economic advantages due to the ease of positioning and material savings. Application example: ventilated roof Creation of a flat ventilated roof on an existing slab: - Positioning of the humidity barrier. - Positioning of the insulating layer. - Creating the sloping screed. - Positioning of the Iglu® formwork H 4, 8, 12 cm. - Positioning of the welded mesh 0 6...
