Play it safe!

thermotec® insulation not only shaves weeks off your construction time, but also prevents sound and thermal bridging, as well as mould growth. Thanks to our thermotec® products: little water, little binder = short drying time!

This has established us as an innovator and market leader in the construction and insulation industry and in the manufacture of insulation materials for more than 30 years now.

thermotec® is not the same as polystyrene or lean concrete!

Polystyrene concrete has a dense cement structure and therefore offers only low insulating properties.
This means that up to twice the installation thickness is required to achieve anything like the thermal and impact sound insulation values of thermotec®.
This in turn results in very long drying times and a high risk of mould forming!

Why Thermotec

Public buildings

thermotec® ensures safety and you benefit from long-term cost savings, energy efficiency and sustainability through eligibility for subsidies.

Indoor & outdoor pools

Die thermally insulating pooltec® Premium backfilling and pooltec® Premium insulating floor slab of thermotec® slab extend the swimming season by months!


Open-plan offices, car workshops, warehouses – our highly resilient thermotec® loose-fill insulation can handle heavy loads.

Computer-controlled mixing systems

The thermotec® MIXMOBILE are PC and...

The precise interaction of water, binding agent and polystyrene is very important for the quality of the insulation. Water plays a major role in the drying times; this means that the less water there is, the faster work can continue. The strength and load-bearing capacity of the insulation can only be achieved by keeping to the exact mixture. Each individual polystyrene bead is surrounded by thermotec® to form a homogeneous mass without thermal and impact sound bridges. In this respect, too, the correct proportion of each component is decisive.

Only computer-controlled mixing systems can achieve the exact grammage and at an incredible speed.
