ICF Insulated concrete form

The polystyrene blocks (also called ICF) have existed for 50 years, but until 10 years ago were virtually unknown in the world. Today in North America have a market share of over 6% and now this type of construction is doing its rapid advance in Europe.

Insulated concrete form or ICF is the name of the construction technology consists of formwork or shuttering insulating polystyrene foam made to build concrete walls. They remain in place after the laying of concrete reinforcing walls and thermally isolating them with excellent returns. They have remarkable properties aseismic.


The formwork STYRO STONE are modular and allow you to build the entire structure leaving a cavity inside the walls erected on which will later be inserted steel armor made up of rods and cast concrete that will consolidate definitively walls. After solidification of the concrete forms remain in place.

The construction with STYRO STONE is fast, both for construction companies and for those who builds its own, both for home use, for industrial use or for the construction of swimming pools. 3-4 experienced workers supplement the walls of the plans of a detached single family of medium size in one working day. Is can also create tracks inside for the realization of the hydraulic system and electrical system. The K values of the finished walls ranging from 0.29 to 0.14 for walls with a thickness of only 25 - 35 cm.

The blocks STYRO STONE are available in white flame retardant polystyrene and made of Neopor®. The greater convenience concerning the system for construction of STYRO STONE is represented by the rapidity of use of prefabricated parts that allow for the construction work at a lower cost. A single block of STYRO STONE is the 0,250 m2 in the area over a wall, resulting in a load absolute minimum in the work on the site of the manufacturer. According to the principle of overlapping blocks like Lego © adult, assembling them becomes child's play. This eliminates the dependency of a skilled worker. By adjusting the lengths of the blocks are also easy, simply requiring a hand saw to cut and form these to any size than the standard ones. Once cut, the individual shapes and corners are joined together with foam PVC.
