Strict thermal regulations in Austria (under OIB Richtlinie 6 and Klimaschutz targets) require top-tier thermal and cryogenic insulation. The following four products are widely requested by Austrian HVAC engineers and EPC contractors.
Austria is pushing aggressively towards climate neutrality by 2040 (Klimaneutralität 2040). Consequently, building and plant designs must comply with stringent regulations including ÖNORM H 5155 (thermal insulation for pipelines and vessels) and the latest OIB-Richtlinie 6 guidelines. The application of high-density, closed-cell rubber foam insulation sheets and tubes is vital for eliminating thermal bridges, lowering energy waste in district heating/cooling projects, and minimizing building operating emissions.
Especially in Austrian urban centers like Vienna, Graz, and Salzburg, where district heating networks and high-efficiency ventilation systems are ubiquitous, moisture management within insulation layers is of paramount concern. Conventional insulation materials, if compromised by moisture, lose their thermal protection capacity. Our NBR/PVC flexible elastomeric foam boasts an exceptional moisture vapor resistance factor (μ ≥ 10,000), protecting Austrian steel and copper pipes from corrosion under insulation (CUI).
From Alpine tourism infrastructure (refrigeration for indoor snow machines and district cooling networks) to Linz's heavy machinery and steel mills, the demand for rubber foam insulation varies widely. The mechanical and chemical resistance requirements in high-humidity Alpine environments highlight the importance of NBR's physical elasticity down to -40°C, and down to -200°C for specialized multi-layered cryogenic systems.
Our solutions provide excellent resistance to UV radiation and ozone when combined with proper cladding, making them perfectly suited to handle the wide seasonal temperature swings of the Austrian climate—from freezing Alpine winters to hot summers in the lowlands.

Contact Our Austrian Support DeskAs a global leader in flexible insulation systems, Kingflex provides advanced solutions tailored to meet the dynamic needs of various industries. We leverage raw material formulation modifications to deliver targeted, high-performance properties.
Integrating acoustic barriers within closed-cell rubber foam structures allows for simultaneous thermal insulation and noise control. This is ideal for HVAC ventilation rooms in Austrian hospitals, public complexes, and luxury hotels where low ambient sound levels are mandatory.
Our ultra-low temperature synthetic rubber solutions prevent mechanical embrittlement. Through multi-layered insulation construction layouts, Kingflex minimizes structural expansion stress in high-value, deep-freeze industrial piping installations.
Meeting EN 13501-1 fire rating is critical for European commercial buildings. Our modified NBR/PVC sheets achieve excellent Euroclass classification (B-s3, d0 / B-s1, d0 custom options) with self-extinguishing properties that prevent flame spread.
Our elastomeric insulation sheets and rolls are precision-manufactured under continuous extrusion to ensure uniform closed-cell size and density distribution. This guarantees reliable performance across all installation areas.

As EU environmental regulations evolve, Kingflex is updating its manufacturing processes. By moving towards water-blown and CO2-blown technology, we eliminate chlorinated and fluorinated hydrocarbon compounds from the foaming process. This aligns our products with the Austrian Federal Ministry for Climate Action, Environment, Energy, Mobility, Innovation and Technology (BMK) directives on building materials decarbonization.
Furthermore, our materials are certified to contain zero VOC emissions, making them fully compatible with indoor building standards like BREEAM and LEED certifications, which are increasingly required for premium office and public builds in Vienna and Graz.
Standard elastomeric foams utilize halogenated flame retardants to achieve higher fire performance ratings. However, when exposed to fire, halogens can release toxic smoke. Kingflex's engineering team is developing advanced halogen-free rubber foam compounds. These formulations aim to meet Euroclass EN 13501-1 s1 smoke density classification without compromising flexibility or thermal conductivity, setting a new benchmark for escape route safety in tunnels and hospitals.
Procuring raw insulation materials across international boundaries requires strict adherence to European norms. Here is how Kingflex ensures seamless integration into your local projects:
