3 1. Styrodur C Thermal Insulation Styrodur C is BASF s environmentally friendly, extruded polystyrene rigid foam. It is free of CFC, HCFC and HFC and makes an important contribution towards reducing emissions of carbon dioxide (CO 2 ). Due to its high compressive strength, low moisture absorption, long working life and its resistance to decay, Styrodur C has become synonymous with XPS in Europe. The compressive strength is the main distinction between the various Styrodur C-types. Effective thermal insulation with Styrodur C reduces energy consumption with the result that the investment in thermal insulation can be recouped within a short period of time. It makes for healthy and comfortable living and protects the building from the effects of moisture as well as high and low temperature. Styrodur C is manufactured according to the requirements of the European norm and its reaction to fire has been classified as Euro Class-E according to It is subject to extensive assurance tests from Wärmeschutz e.v. and has been granted the approval no. Z from the DIBt, the Institute of the Federal and Länder Governments for a uniform fulfillment of technical tasks in the field of public law. 31 Styrodur C Thermal Insulation

4 2 Advantages of Styrodur C 3 Load Bearing Applications 2. Advantages of Styrodur C Styrodur C is used for the reduction of heat losses, to increase your comfort of living and to protect buildings from damages. Among other conditions it is oftentimes subject to heavy loads. Examples for such heavy loads are: Earth thrust Structural loads (furniture, superstructural parts, merchandise) Dynamic load (vehicles e. g. for transport) and Greening and patio surfaces For many applications, compressive strength is the crucial factor in choosing the right insulation. For construction purposes it is also important that the insulation is not subject to brittle fracture when used on uneven or inhomogeneous ground. Despite its high compressive load, Styrodur C is elastic to such extend that it adjusts to any unevenness and reacts to peak loads with plastic deformations rather than with material damage. If the load, the type of load and the extension and duration of the load effect is known, the existing compressive strength within the insulation board can be calculated. There are various types of Styrodur C for all different strains. For choosing the right type of insulation it is important to know whether the strain is short-term or permanent. The existing compressive strength must not exceed the maximum strength allowable for the insulation. For more than 40 years, Styrodur C has proven valuable when it comes to load bearing insulation.

Load Bearing Applications Why you need heat insulation Floors protect living-, working- and common areas against surrounding air, colder rooms or directly against the ground. In a single family detached house the heat loss of the floors against the basement or the ground are up to 20 % of the total heat loss of the house. Minimum heat insulation DIN determines the minimum insulation values for living areas heated to the average indoor temperature ( 19 C). Regulating the minimum heat insulation shall protect the residents from health problems caused by low temperatures of the perimeter walls and structural damages caused by condensation. The Energy Saving Ordinance (Energieeinsparvordnung EnEV) The Energy Saving Ordinance is a basic element of today s climate protection policy. In requiring the consideration of heat insulation when calculating the annual demand for thermal heat and the annual demand for primary energy the EnEV makes way for an economic combination of constructional heat insulation as well as industrial and building systems.

5 Styrodur C below Foundation Slabs n Load Bearing Applications on Roofs 4. Applications 4.1 Styrodur C below Foundation Slabs Styrodur C meets every requirement for heat insulation in cellar rooms. It provides high compressive strength, resistance to decay and low moisture absorption. It has been state-of-the-art building insulation for many years now. Styrodur C can also be used as thermal insulation for foundation slabs (Fig. 3). Fig. 5: The frost protection layer is put into the ground below the frost line. 4.2 Load Bearing Applications on Roofs Styrodur C is used for the following applications: Roof terrace Green roof Parking roof Fig.3: Insulation of a foundation slab with Styrodur C. In more and more houses and office buildings, foundation slabs from reinforced concrete are being used for the foundation. In order to avoid thermal bridges, it is advisable to lay Styrodur C below the foundation slabs and directly attach the perimeter insulation of the basement wall. Lohr Elemente E. Schneider GmbH from Gemünden (Germany) offers prefabricated elements of Styrodur C for the production of round formwork for foundation slabs and anti frost heave constructions. For such an application the thermal insulation is extended into the ground beyond the foundation slab to prevent frost heaves below the foundation (Fig. 5). In order to increase the housing quality of a building many flat-roofs are being converted into roof gardens. On inverted flat roofs, Styrodur C can protect the roof sealing from mechanical damages and high thermal strain. It can handle heavy loads without difficulty due to its high compressive strength. Styrodur C is also applicable with point loads e. g. from stilted pavement slabs, distributed loads e. g. from storing the slabs in coarse gravel or for the conversion into a roof garden.

6 Load Bearing Applications and Floor Insulation n Styrodur C for Road Construction Due to the increase of inner-city traffic, parking places become scarce. Therefore, many roofs of public buildings and large department stores are converted into parking roofs. To compensate for any heat loss of the heated top levels against the surrounding air, the roof is being insulated with Styrodur C following the inverted roof concept (Fig. 7). The high compressive strength of Styrodur C guarantees limitless stability under the load of parked or driving vehicles. Fig. 8: Frost protection for track beds with high compressive-strength Styrodur C. Applied in road beds, Styrodur C prevents the penetration of frost into the ground thus avoiding frost heaves as well as deformations of the road. In addition it reduces the necessary depths of the road bed, which leads to fewer construction and maintenance costs. Fig. 7: Parking roof with concrete slab pavement on inverted roof with Styrodur C. 4.3 Styrodur C in Road Construction Styrodur C also demonstrates its outstanding properties when it comes to heavy loads: If the ground is insulated with Styrodur C it can sustain the heaviest load being inserted into the ground via the props of a tripod construction. Applications in Road Construction: Track beds Road beds Airports If the ground is exposed to frost heave its lifting and sinking can lead to uncontrolled deformation of the tracks. For such cases, Styrodur C can avoid the penetration of the frost into the material and the creation of ice lenses within the substructure (Fig. 8). The subgrade protection layer can be significantly reduced when using Styrodur C. Heavy dynamic loads caused by rail traffic constitute the utmost quality requirements for Styrodur C.

7 Styrodur C for Ceilings in Unheated Attics n Styrodur C in Floors 4.4 Styrodur C Ceilings against Unheated Attics A lot of energy is saved if the upper side of a building s top floor above the living areas is insulated. The Styrodur C boards can be topped with running boards, hardboards or floor pavement depending on how the room is being used. In order to achieve a thermal transmission coefficient of approx W/(m 2 K) one needs an insulation layer of approx. 14 cm. Since the attic and any chimneys therein are no longer heated, it is necessary to check for the possible danger of condensation from the fumes within the chimney. 4.5 Styrodur C in Floors Styrodur C is also used for: Perimeter insulation Industrial construction Warehouses Cold storage houses Ice rinks Airplane hangars Depending on the way they are being used, floors are subject to various kinds of heavy loads. Warehouses for example, are subject to compressive stress caused by heavy storage goods or heavy vehicles such as forklift trucks. Additionally, in cold storage houses a consistently low temperature has to be kept at all times. With Styrodur C you can achieve just that (Fig. 12, 14, 16 and 17).

Wheel load 4.6 Styrodur C in Floors above Unheated Basements without Subsonic Noise Protection For floors in rooms above unheated basements we suggest a thermal transmission coefficient of 0.35 W/(m 2 K). You can achieve this e. g. with a 16 mm thick reinforced concrete floor slab with 50 mm of floor pavement and an insulation with 10 cm Styrodur C. 4 Applications Block paving Sandbed Geomembrane Gravel layer 8/16 Geomembrane Thermal insulation Styrodur C Sealing Reinforced concrete floor Fig. 15: Wheel load on floor insulation with Styrodur C.

9 Styrodur C in Floors with Subsonic Noise Insulation and Floor Heating above Unheated Basements n Styrodur C Insulation against the Ground with Floor Heating 4.7 Styrodur C in Floors with Subsonic Noise Protection and Floor Heating above Unheated Basements For floor heating we suggest a thermal transmission coefficient of 0.35 W/(m 2 K) for the construction components between the heated floor and the unheated basement. Should a subsonic noise insulation be necessary, we recommend the combination of a soft subsonic noise insulation board and hard Styrodur C boards. You need 8 cm of Styrodur C for a 35/30 subsonic protection board (Fig. 20). The subsonic noise insulation board adjusts to the unevenness of the slab and together with the edge-trim guarantees for the subsonic noise insulation. The hard Styrodur C board offers the necessary additional thermal insulation while at the same time providing a solid ground for the pipes of the hydronic floor heating (Fig. 21).

We suggest 12 cm of Styrodur C. Fig. 20: Floor insulation with subsonic noise protection in living areas. 94 Applications 9

10 Styrodur C for Top-Side Insulation of Floor Slab in Industrial Construction 4.9 Styrodur C for Top-Side Insulation of Floor Slab in Industrial Construction The top side insulation of floor slabs is especially recommendable for subsequent thermal insulation of existing industrial floors and for the installation of a floor heating system (Fig. 23). The Styrodur C boards are conjoined on top of the floor slab and covered with polyethylene. On top, a concrete slab is installed in order to balance the load of e. g. forklift trucks or the feet of shelves.
