摘要：
To prevent the insulating effect from deteriorating and the associated loss of heat, Logstor Ror A/B, of Logstor/Denmark, uses a diffusion foil as standard in all continuously-produced pipes of every size. The diffusion foil retains the gases but simultaneously allows small volumes of water from the medium pipe to permeate. The company also offers a special calculation program with which the heat loss from new and aged pipes and without diffusion foils can be calculated.
