Iglu'® ventilated cavities, crawlspace

Disposable formwork for ventilated under-floor cavities

Iglu’^_® is a market leading product that was created and patented for the realisation of crawlspace, 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 Iglu’® 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 Iglu’_^® formworks, placed side by side in sequence according to a predefined direction, make it easy to quickly create a self-supporting pedestrian platform above which a layer of is cast in order to easily and economically create a ventilated slab placed on pillars with the below cavity area available for the passage of systems but above all ventilated to counteract rising humidity and radioactive gases.

ADVANTAGES

A ventilated under-floor cavity created with Iglu’_^® 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).

Danger of Radon gas and rising humidity in a home built on a traditional foundation.

Installation

Dry assembly method

1. Position the first element to the upper left with respect to the work surface, making sure that the arrow is pointing up.

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.

3. To unite the units in sequence, be careful to perfectly link the “male-female” hooking elements at the base of the support feet (see photo sequence.

Method for creating under-floor cavities

1. Preparation of the natural ground.

2. Preparation of the lean concrete foundation, to be sized according to the loads and capacity of the ground.

3. Positioning the L-Plast panel around the foundation beams after positioning the necessary reinforcements.

4. Positioning the linking male/female formworks, working from the left to the right, from the top down, making sure the arrow is facing upward.

5. Laying the welded mesh Ø 6 20×20 above the formworks.

6. Casting the concrete starting from the centre of the arc, letting it go inside the legs of the Iglu’®.

To ensure a correct installation and perfectly created under-floor cavity please refer to the product’s usage requirements.

ACCESSORIES

L-PLAST

L-Plast is used for new constructions to create the slab and foundation beams with a single concrete casting; when restructuring is used to easily create reinforcement curbs for existing foundations.
Furthermore, L-Plast is ideal for creating air ducts in general, such as for cold rooms, for example (if forced ventilation is necessary) or in geothermal applications where air must be blown into the under-floor cavity.
When restructuring, when the existing walls must be reinforced or when an underpinning must be created, L-Plast is a useful work tool that helps creating a new slab or reinforcement base with a single casting.

PIBI-Stop

PIBI STOP – for diagonal beams.
It is a casting stop panel for obstructing, as needed, the “side tunnels” of the individual Iglù^® and is available for all heights. Given its ease of positioning , PIBIstop is optimal for creating foundation beams without the need to use classical wood shuttering.
In combination with Iglù^®, it is ideal for creating diagonal beams. Finally, based on its characteristic of being connected to the individual unit, it is particularly suited for reconstruction where an underpinning must be created where the existing structures are often not squared.

Iglù® and Iso Iglù® are the best solution for the building insulation

ISO IGLU’®

The combined use of Iglù^® and Iso Iglù^® saves time when working as the number of concrete castings are reduced to only one; the slab that is created also provides continuous insulation. The systems can be positioned in the soffit of the polystyrene panels before casting the slab. The surface can then be machine smoothed to adhere to the pavement. In conclusion, Iglù^® with the accessory Iso Iglù^® makes it possible to create a slab with a sanitary space and an insulated floor with reduced positioning times. In this case, as the Iso Iglù® panels prevent the filling of the pillars, the slab will be a true slab to be suitably dimensioned and reinforced.
Iso Iglù^® is a polystyrene panel with dimensions of 100 x 100 cm. It makes it possible to create a concrete structure with crossed ribbing with surrounding supports (walls and foundations).

PROLUNGA

The extension element/product is made of recycled plastic and allows the development of ventilated slabs of any shape or size.

Its advantages are: registration the extensibility of the element up to almost 50 cm in length; casting of the foundation grid and the ventilated slab in a single phase with savings in reinforcement and dismantling operations; perfect development of the ventilated slab even for plans of complex shapes and sizes; reduction in formwork shaping.

BETON UP

BETON UP – for monolithic slabs.
Beton Up is an accessory for the Iglù^® system (or Atlantis) that prevents the concrete from forming pillars. In this way, the formworks take on the simple function of scaffolding on which a monolithic reinforced concrete slab can be created that is bound to the surroundings. With Beton Up the slab is not self-supporting.

The use of Beton Up is necessary when a ventilated floor must be created when the ground is excessively deformed or when the clearance must be increased between two supports and form, for example with the combined use of Atlantis, an inspectionable tunnel.

FREQUENT QUESTIONS

Can IGLU’®PLUS and IGLU’® be walked on during installation?

Iglu’® Plus allows total dry walkability, in any area of the shell, even without the prior laying of the reinforcement mesh. For the Iglu’®, on the other hand, refer to the provisions of the instructions for use.

How to position the pipes for ventilation?

To obtain a natural “chimney effect” it is necessary to position the entry holes on the north side, at a height slightly above the ground, and the exit holes on the south side, at the highest elevation (preferably up to the roof), taking care to connect between they the different compartments of the foundation grid so that the entire crawl space is intercommunicating. The ducts placed inside the wall facing south will overheat cause an upward motion by sucking in the air in the crawl space.

Why choose IGLU’® and/or IGLU’® PLUS?

The quality and specificity of the raw material used (Alaplen®), the particular shape, the size, the thicknesses, the surface quality, the care of the packaging, the ease of assembly, the resistance and the processing techniques make Iglu ‘ ® the product of excellence.

Features that become even more exciting for the Iglu’® Plus.
