Pro Clima Adhesive Tapes Tested For 100 Years

Tuesday 14th April 2015

Adhesive tapes which are applied to attain airtightness in accordance with DIN 4108-7, SIA 180 or OENORM B 8110-2 should have a durability of 50 to 100 years.

Permanent airtightness with Pro Clima!

  • Reliable functioning tested for 100 years
  • Independently confirmed
  • Maximum requirement significantly exceeded

Adhesive tapes which are applied to attain airtightness in accordance with DIN 4108-7, SIA 180 or OENORM B 8110-2 should have a durability of 50 to 100 years - after all, this is the expected service life of thermal insulation layers to ensure that they protect against damage due to convection and moisture vapour ingress. 

A process for accelerated ageing of adhesive tape joints has been developed at the University of Kassel as part of a research project on 'Quality Assurance for Adhesive-based Joint Technology in Airtightness Layers'. With this process adhesive tapes have to demonstrate specified minimum tensile strengths after being stored at increased air temperature and humidity (65 degrees C and 80% relative humidity) for a period of 120 days (this corresponds to around 17 years in reality). On successful completion of this test an adhesive tape can be regarded as permanent.

As part of the tests to ascertain the durability of airtight joints, Pro Clima's Tescon Vana, Uni Tape and Tescon No.1 adhesive tapes have also been subjected to accelerated ageing at the University of Kassel under the conditions described above. At the request of Pro Clima, the test period was increased from 120 days to 700 days. Accelerated ageing for 700 days corresponds to 100 years in reality. The test results for the three adhesive tapes from Pro Clima were also positive for this increased period of accelerated ageing.

These demanding tests with increased test periods have confirmed the suitability of Tescon Vana, Uni Tape and Tescon No.1 adhesive tapes for the creation of permanent airtightness which surpass the requriements of DIN 4108-7, SIA 180 and OENORM B 8110-2. This confirms that vapour check and airtightness membranes and airtight wood-based panels can be reliably bonded using Pro Clima products!
