The power of BelgaClima air tightness products

BelgaClima supplies a well-balanced and high-quality range of air tightness products.

The BelgaClima range consists of innovative products to create an air tight and wind tight layer for your new or existing home, especially for low-energy and/or passive buildings.


BelgaClima clients get much more than a product. By supplying complete solutions for air tightness, wind tightness and weather protection with coordinated products, they can benefit of experience, detailed knowledge and a product warranty for the preferred system.


Another aim of BelgaClima is, to offer a qualified support to our private and commercial clients (architects/ engineers, builders/ developers and installers) through consultation and customised training modules in order to achieve the best results for air tightness and protection of the building structure for their projects.



Know-how, training, interaction and a clear focus on service all together makes BelgaClima to a unique comprehensive concept for air tightness and building protection.

We´ve been often asked about NSAI and other certifications for our air tight products.

Please notice the following facts:

  1. The CE marking to IS EN 13984 has replaced the requirement for NSAI Agrément certification from July 1st 2013, which means that there is no additional requirement in the form of a National Annex to the standard for air tight membranes here in Ireland anymore.
  2. Due to a missing harmonised European Standard there is no CE marking for some air tight products like air tight tapes (window tapes & tapes for membranes) available so far.
  3. The most available air tight tapes (including our full range of air tight tapes) fulfill the requirements of national standards, e.g. the German DIN 4108/7 (Thermal insulation and energy economy in buildings - Part 7: Air tightness of buildings)
  4. The new German standard DIN 4108/11 specifies minimum standards regarding the bonding performance of air tight tapes and sealants. The tapes and sealants of our product range meet and exceed the required specifications.
