ISOTEX, BUILD WITHOUT A STRUCTURAL FRAME, INFILL WALLS OR EXTERNAL INSULATION
Laying has never been so quick and easy
The most complete and competitive building system
The most complete and competitive building system
Isotex Srl manufactures a complete building system, made up of formwork blocks and wood-cement floor slabs for constructing safe, efficient and sustainable buildings.
- With a single, quick and simple laying operation, you get an earthquake-resistant load-bearing structure, thermal and acoustic insulation and a high level of fire safety (REI120-240 without plaster, B,s1-d0, Lepir2 Test);
- With Isotex you eliminate beams, columns, infill walls and external thermal insulation, halving build times and guaranteeing cost certainty (buildings of 8–9 storeys already completed);
- On request, the supply can include structural calculations and qualified installation teams.

Over 40 years of challenges, all of them won!
We have become the largest European manufacturer of wood-cement formwork blocks and floor slabs, championing a new way of building. As far back as 40 years ago, our buildings were earthquake-resistant, energy-efficient, acoustically insulated, fire-resistant and sustainable. Our research never stops. Our aim is to give designers and contractors a competitive and complete system, and to ensure people enjoy comfortable and safe homes.
Do you know what a finished Isotex wall really costs?
With Isotex you eliminate beams, columns, infill walls and external insulation in a single laying stage. Qualified installation teams and structural calculations included. Build in half the time while cutting site costs.
