Product benefits

Kaiflex ST closed-cell synthetic rubber insulation features universal applicability. It can be used for hot and cold pipes, for any system size and different pipe diameters, in small furnace rooms and in large projects. Thanks to the wide product assortment and the right options like Kaiflex ST tape and Kaiflex RT-ST pipe supports, the material can be used for products of any size without switching material or manufacturer. All this has made Kaiflex ST the Kaimann standard in technical insulation.

Kaiflex ST is used in cooling and air conditioning systems for insulating pipes and ducts in highly frequented public and commercial buildings, like airports, large office complexes, hotels, and apartment buildings, as well as in industrial plants and ships. Thanks to its antimicrobial and fibre-free structure, the material meets high hygienic requirements and is especially suitable for insulation in healthcare facilities like hospitals.

Tested and certified - very good technical attributes

Extensively tested and internationally certified, Kaiflex ST features broad usability and technical characteristics of the highest standard. Thanks to its very low thermal conductivity of up to λ ≤0.033 (W/m·K) at 0 °C and outstanding water vapour diffusion resistance of up to μ ≥10,000, this Kaimann insulation is very energy-efficient and reliably prevents condensation. At Euroclass B-s3, d0 (DIN EN 13501-1), Class O (in acc. with UK building regulations) and Class 1 very low surface spread of flame (test acc. to BS 476-7), this elastomer insulation also meets the highest safety requirements regarding fire behaviour.

The very good technical characteristics remain consistently high across all insulation thicknesses, and ensure reliable insulation performance over the entire operational life of the system. Even at low insulation thickness, this proven material protects long-term from energy losses, acts as an effective water vapour barrier and so minimizes the risk of corrosion under insulation.

The material is available in sheets, as a standard or self-adhesive product. Whichever version is chosen, its flexible installation makes Kaiflex ST a winner.

Environmental Product Declarations (EPD) make the ecological assessment of Kaimann insulation materials even more transparent. In this way, the company assists in the planning and certification of sustainable buildings.

Product highlights

Pictogram, Water Diffusion

Reliable prevention of condensation

Dew formation can lead to damage to insulation as well as technical equipment. Due to its closed-cell property, Kaiflex keeps pipes and ducts dry and prevents corrosion under the insulation (CUI).

Pictogram, Thermal Efficiency

Excellent thermal values minimise energy losses

Inadequately insulated technical installations generate increased operational costs. Kaiflex has low thermal conductivity, which results in lower energy losses and increases the efficiency of the entire installation.

Pictogram, Fire

High safety due to good fire behaviour

The requirements for certified safety in case of fire have increased worldwide for elastomeric insulation materials. Kaiflex reduces the spread of fire and smoke, is self-extinguishing and does not drip off when burning.

Pictogram, Antimicrobial

Anti-microbial finish

Mould growth can affect indoor air quality. Kaiflex provides effective protection against moisture penetration, is naturally anti-microbial and resistant to mould growth, leaving bacteria no chance.
