Plastic dome for ventilated hollow floor

Aircrab is the ultimate solution for ventilated crawl spaces, air space buffers, or gaps for utility pipes, typically between the ground and civil or industrial buildings, that improves the comfort of the living environment. This system helps to remove the unsightly and unhealthy effects brought by condensation and mold and allows enhanced thermal performance. 
 The connection with the outside by simple pipes allows a natural air flow to cross the interspace, eliminating moisture and cooling the foundation during summer. The use of EPS guarantees thermal insulation. AirCrab makes it possible to build quickly a self-supporting platform, hooking the parts according to a predefined sequence. Concrete is then poured, creating a simple and low-cost ventilated floor slab, a real gap that can also be used for utility pipes and components. 
 AirCrab is entirely made of Expanded Polystyrene (EPS), which is flame retardant and non-toxic; thanks to such material, AirCrab is particularly recommended for floor heating / cooling as it ensures a constant internal temperature of the environments. Heat spikes are avoided and radiant temperature is almost constant, which contributes to a feeling of great comfort. The ventilation of the crawl space heats up the cold winter air, which comes out enriched by any humidity present in the interspace. When it comes to floor heating, AirCrab proves to be a precious ally in preventing heat loss; the mass of the slab, inside the foundations, acts as an accumulator, while the insulating layer prevents the return of the cold from the floor below the foundation.
