Our preinsulated pipes are manufactured using a closely monitored production process. This means we can be 100% sure that the insulation foam is consistent, and that the carrier pipe, insulation and outer casing are perfectly assembled. All connection sets and fittings are also designed to avoid weak points.
Our latest LOGSTOR technologies ensure that the gases which provide the exceptional insulation (down to lambda 23) remain in the pipe, and that the performance is constant for its entire service life. A special diffusion barrier retains the cyclopentane and carbon dioxide in the insulation, and also prevents nitrogen or oxygen from soil or water from penetrating.
The advantage is that the foam does not break down and the insulation property remains constant for the entire service life of 30 years – in line with EN 253. This is especially important for pipes with small diameters up to DN 200.
