Product benefits
The requirements for structural fire protection, and in particular the increased focus on personal safety in case of fire, have been increasing internationally for years. More and more, limited smoke development has to correspond to an “s2” smoke development class in accordance with EN 13501-1 as the minimum requirement for flame-retardant building products. Kaimann meets these enhanced requirements and offers increased fire safety with its Kaiflex ST s2: The insulation material made of closed-cell rubber emits limited smoke to s2 standards and is self-extinguishing as well as non-dripping. These properties mean that the insulation material meets the demanding European requirements for combustible building materials such as MVV TB, VKF RF2, Class O (in accordance with UK Building Regulations) and Class 1 (tested in accordance with BS476-7) for surface spread of flame.
The universal insulation material for flexible use
Kaiflex ST s2 is attractive not only because of its reliable fire protection, but also with its universal applicability. Thanks to its wide product range and in combination with the system benefits of pipe supports and special adhesive, the insulation material can be used for any size of project without having to change materials or manufacturers. Kaiflex ST s2 thus presents itself as the Kaimann standard in technical insulation.
This means that the insulation material can be used for cold and hot pipes and on different pipe diameters – both in small boiler rooms and in large-scale projects. It reliably prevents condensation and corrosion from forming, particularly in systems featuring alternating temperatures, which are being installed increasingly frequently, and when correctly dimensioned, it simultaneously fulfils the legal requirements for hot water and heat distribution systems. It is used in cooling and air conditioning systems for insulating pipes in highly frequented public and commercial buildings, like airports, large office complexes, hotels, and apartment buildings, as well as in industrial plants and in shipbuilding. Thanks to its antimicrobial and fibre-free structure, Kaiflex ST s2 also meets high hygienic requirements and is especially suitable for insulation in healthcare facilities, such as hospitals.
Tested and certified – very good technical values
It is not just its versatility that makes Kaiflex ST s2 impressive, but also the very highest level of technical specifications: its very low thermal conductivity and the best water vapour diffusion resistance values makes Kaimann insulation material extremely energy-efficient and provides sustainable protection against energy loss. It effectively acts as a vapour barrier and reliably prevents condensation, greatly minimising the risk of corrosion underneath the insulation. This means Kaiflex ST s2 ensures reliable insulation performance over the entire operational life of the system.
Kaiflex ST s2 hoses are available as a standard product or self-adhesive in 2 and 1.2 m lengths. Whichever variant you choose, it is easy to work with.
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.
