Who are we?

Fixolite, located near Charleroi, south of Brussels in Belgium, specialises in since 1945 in the manufacture of insulating building materials.

Including Hi blocks (High Insulation) or tunnel box for Hi shutter enabling the creation of BBC or passive housesFixolite is the answer to European standards in force.

Production is exported to various countries European countries such as France, Germany, Italy, Portugal and the Netherlands, as well as in North Africa. These materials are used in the construction of buildings such as  schools, sports halls, detached houses, blocks of flats or flats, industrial and tertiary buildingsetc. ...


The Fixolite blocks are made up of wood/Portland cement and conventional or graphite insulation (inside or outside). The blocks are dry-assembled (except for the first row). Concrete is then poured to provide a solid surface. mechanical strength to the whole, while also ensuring thermal inertia and a acoustic comfort (RT 2012). The blocks are manufactured at our Fixolite factory in Belgium and also at our Isobloc in Italy.

While the principle is exactly the same between Fixolite blocks (Belgium) and Isobloc (Italy), the block models are different with advantages for each.


The tunnel boxes are made up of a polystyrene shell (with steel reinforcement). The external part will be clad with fibre, brick, concrete or ribbed (PSE) cladding. Fixolite lintel boxes can then be fitted with all the roller shutters on the market.
