Application

K-FLEX ST is a multi-purpose flexible elastomeric thermal insulation with a built-in vapour barrier and a closed cell structure, this makes K-FLEX insulation a high resistance to water vapour transmission which in turn enable the material to maintain a high level of energy conservation efficiency.

K-FLEX ST is a dust and fiber-free insulation that makes it an ideal product for apartments, commercial buildings, industrial plants, the oil & gas industry, marine and offshore applications.

K-FLEX ST is the ideal choice for:

Refrigeration pipework.
Large pipes and tanks.
Hot water piping system.
Chilled water piping system.
Ducting system.
Drainage system.

Advantages

Low flame spread

When fire-tested K-FLEX ST, it does not generate flaming droplets and has a low fire propagation index. These combined meet the fire performance requirement of class “0” as defined in Building Regulations. Further guarantee is given by supervision contracts with independent European laboratories.

High water vapor diffusion resistance

K-FLEX ST closed cell elastomeric insulation has a high water vapor diffusion resistance factor µ, that minimizes water vapor penetration, giving an excellent long-term performance.

Very low thermal conductivity

K-FLEX ST thermal coefficient is λ 0°C = 0.032W/(m·K). The thermal conductivity coefficient is the most important factor in calculations focused on energy saving.
