Dynamic insulation. Dynamisk isolering

Reviews the present state of development of dynamic insulation systems. Describes the advantages and disadvantages and assesses probable applications. Earlier articles and reports on dynamic insulation are listed and commented on. The second part deals with the ventilation design aspects for practical application of dynamic insulation in buildings. One of the points is concerned with how the air flow through the insulation is affected by changing external climate conditions. The risks of condensation in the insulation, particularly with coincident flow systems, is discussed. Claims that, correctly applied, the principle is more or less insensitive to thermal fluxes, but that theeffect of wind may be of some importance.
