Combi Isolatie BV has been a specialist in cold insulation for over 35 years.

Cold insulation
We talk of cold insulation if the medium temperature (such as the temperature of the piping) is lower than the environmental temperature. If the outer surface of the object is below the dew point, condensation will occur.

Insulation to prevent condensation
To prevent condensation the insulation thickness is determined to ensure that the temperature of the outer surface never goes below the dew point. In other words, the dew point must be in the insulation itself. To prevent vapour diffusion through the insulation serious attention must be paid to the vapour-inhibiting membrane of the insulation. Even if the insulation material is damp-proof, it requires attention. The seams can be a weak link in the insulation system. The seams must be sealed with a suitable sealer to prevent moisture from moving toward the cold object through the seams. By installing the insulation in two mortar-patterned layers, the route toward the cold object is made as long as possible.

Insulation to prevent high energy bills
Prevention of condensation is the main concern for the above-mentioned insulation thickness calculation.
With an eye towards the expected rises in the cost of energy we also increasingly notice that the calculation of economical insulation thickness has become a “hot” item.

It should be clear that in relation to the insulation of cooling and/or freeze solutions and applications, one must work with a high degree of diligence and care. If the insulation is not completely damp-proof, this will cause irrevocable problems. Moisture in the insulation will severely decrease the entirety’s insulation value. Additionally, in relation to freeze solutions, ice may develop, which could cause the insulation to freeze, with disastrous consequences.
Because the insulation system is only as strong as its weakest link, we devote attention to all of the facets. These are:

1) The conversation of the object.
2) The choice of the most suitable insulation material, and the correct insulation thickness.
3) The choice for the most suitable installation method.
4) Protection of the damp-proof layer.
5) Selecting the most suitable finishing/furnishing layer.
