Save energy and prevent condensation

Properly insulating hot and cold water pipes leads to significantly lower energy consumption and protects pipes against corrosion and condensation.

Insulation sanitary system

The benefits of proper insulation of sanitary systems:

  • Lower heat loss through pipes 
  • Faster hot tap water  
  • Protection against freezing
  • Lower heating costs
  • No corrosion or mould on pipes due to condensation

Hot water pipes

Insulating hot water pipes prevents unnecessary heat loss where these pipes pass through colder areas, such as basements, crawl spaces, attics, garages and store rooms. Such heat losses cause the heating system to consume more energy. This leads to higher costs and higher CO2 emissions.
Energy savings of 70% can often be achieved by installing tube insulation on pipes. By increasing the insulation thickness by just a few millimetres, this can increase up to 85%. Hot tap water will also be available more rapidly.

Cold water pipes

The temperature in the crawl space under a house or building can drop to the outside temperature via heat loss through the ground. When this space freezes, cold water pipes can also freeze. Insulation can protect cold water pipes in uninsulated rooms, especially when used in combination with heating cables.

Corrosion due to condensation

Condensation can cause corrosion on hot and cold water supply pipes if they are not properly insulated or if the wrong insulation material is used. Insulation materials with an excellent water vapour barrier and good thermal performance protect your pipes and systems against condensation.
Corrosion, mould and other contaminants have no chance to form.

Reducing noise

Water pipes sometimes produce contact noise, as well as noise due to the shrinkage and expansion of pipes.

Our productlines for Sanitary

Our pipe insulation can be used across a wide temperature range and offers excellent long-term insulation properties. Due to the closed cell structure of our PE foams, the insulation forms a strong water vapour barrier, which prevents condensation and corrosion.
