    Extending Potential Applications

    Its particularly high compressive strength makes Styrodur® C ideal for all insulation applications subject to compressive stress. And in the future, developers will have even greater flexibility in the design of insulation under floor slabs.

    Because the general national technical approval for the application of Styrodur C under load-bearing floor slabs has been extended for:

    - Fitting several layers of Styrodur C under load-bearing floor slabs

    - Insulating layers up to 300 mm thick

    Styrodur® C—the optimum insulation for high and low temperatures.

    Reduces your energy consumption and enhances your living environment

    Thermal Insulation — More Than Just Climate Protection

    Optimum thermal insulation using Styrodur® C makes a significant contribution to reducing carbon dioxide (CO2) emissions, the major cause of the greenhouse effect.

    One of the positive effects is that investment in comprehensive thermal insulation measures can be quickly offset by developers as a result of a significantly lower energy consumption.

    Top Insulating Performance— From Floor to Roof

    Perimeter insulation

    The external insulation of structural components in contact with the earth—perimeter insulation—

    reduces heat losses through the building’s foundations. Perimeter insulation surrounds the shell of the building without forming any thermal bridges and securely protects the seal against mechanical damage.


    - Moisture-resistant

    - High compressive strength

    - Aging- and rot-proof

    - Excellent, durable thermal insulation properties

    Floor insulation

    There are a number of requirements regarding insulating materials, floors, and ceilings. The compressive strength in many applications is a key factor in the choice of insulating material.

    Because of its high compressive strength, Styrodur C is suitable for insulating virtually all floor constructions, including floors subjected to heavy loads in warehouses, production areas, and aircraft maintenance hangars, but at the same time it is so flexible that it can adjust to uneven surfaces under pressure and can absorb local peak loads.


    - High load-bearing capacity

    - Dimensional stability

    Interior insulation

    If the building cannot be insulated from the exterior, for instance due to a heritage-protected facade, it is recommended to implement interior insulation of the exterior walls.

    The interior insulation with Styrodur C can be realized with a plaster layer or with drywall siding.


    - Compression-proof and load-bearing

    - Optimal plaster adhesion due to embossed surface

    - Dimensionally stable

    - Low moisture absorption

    Cavity wall insulation

    For decades, double-skin masonry constructions with cavity wall insulation have proved effective in areas subject to high levels of wind and rain, such as coastal regions, and are regarded as a traditional construction in many areas in the United Kingdom.


    - Excellent thermal insulation

    - Water-repellent properties

    - Dimensional stability

    - Durability

    Cold bridge insulation

    It is absolutely vital to avoid thermal bridges for energy, health, and hygiene reasons. Based on the structural components of a building, avoiding thermal bridges is very important for long-term conservation and functional safety.


    - Reduces energy losses

    - Increases internal surface temperatures

    - Prevents the formation of condensation and mold

    Ceiling insulation

    Insulating materials that are quick and easy to assemble and place very little stress on the support construction thanks to their low dead load are particularly attractive for insulating the underside of ceilings. Underside ceiling insulation is a simple and economic way to improve insulation in unheated basement areas and to avoid cold floors above the ceiling.


    - Large tongue-and-groove system

    - Low dead load

    - Quick and easy to assemble

    - Solid, clean, smooth surface

    - Easy to clean with a water jet

    - 120mm Insulation

    Attic insulation


    - High compressive strength

    - Walkable and load-bearing

    - Easy and quick installation

    - Free of thermal bridges thanks to groove and tongue system

    - Durable, resistant to aging and decay

    Inverted roofs

    As a result of solar radiation and low temperatures, flat roofs are exposed to extreme fluctuations in temperature, high thermal loads, and stress, placing very high demands on the seal and thermal insulation. In inverted roofs, the insulating layer is fitted over the seal. The construction is easier and quicker to manufacture than with a conventional single-shell roof because fewer layers have to be fitted and bonded, and the seal thereby becomes more durable.


    - High compressive strength

    - Durable, does not rot or decompose

    - Suitable for foot traffic and heavy loads

    - Dimensional at stablility

    - Protects the seal

    Pitched roof insulation


    - No thermal bridges

    - Even thickness of the insulation layer

    - Can be used in new and existing buildings

    Frost protection under roads and railways


    - Moisture-resistant

    - High compressive strength

    - Aging- and rot-proof

    - Dimensional stability

    Building Systems Using Styrodur® C— Installation Systems

    - Floor slab systems

    - Formwork for ceiling edges

    - Eased frames 

    - Metal profile systems for pitched roofs 

    - Parking deck systems

    - Wet room units

    - Tiles

    - Insulation of refrigerated vehicles (vans)
