4 x 1m Grey Pipe Insulation Foam
Inside Diameter – 35mm
The lagging is made of polyethylene foam formed by foaming polyethylene gas
The resulting product is a foam with closed cell structure, which is a property to a wide range of application of foam for insulating purposes.
They are made of high-quality polyethylene foam in gray.
They serve as an insulating layer for transmission lines for hot and cold water in the building.
Apparent density polyethylene foam – 30 – 35 kg / m³
Resistance to temperatures from -65 ° C to + 95 ° C
Thermal conductivity λ = 0.036 [W / mK]
Longitudinal at 95 ° C under 1.65%
Coefficient of resistance to water vapor diffusion μ 3500
Heat insulation of polyethylene foam has the properties of inhibiting the diffusion of water vapor, which is the protection of pipes from retting and corrosion. In view of the very low water absorption (after 24 hours WAvsr = 0.1 [%]) Coating absorb practically no water.
Production of polyethylene foam also has sound-absorbing properties
