Blistering of sandwich panels

Blistering / bending is caused by thermal forces that occur in a sandwich panel as the result of a so-called thermoshock. This causes the outer skin to become detached from the PUR- PIR / EPS/ mineral wool insulation resulting in hollow spaces being created behind the outer sheet. After heating up, this space will expand and form a blister, swelling or bend.

Blistering in panels

Blistering in panels is evident when:

  • Thermoshock occurs, this can be on building site but also during production.
  • Forced tension, bending, hollowing during assembly, uneven surface, after heating up the stresses possibly cause imperfections.
  • Darker colours of panels increase the temperature of the outer sheet, this can cause more tension.
  • A thin steel thickness of outer sheet can cause more imperfections and the chance of blistering is much higher, cheaper isn't always better.
  • Detached foam to outersheet during production.
  • Less profile in the outer sheet ( flat panels) gives less strength.
  • Problems of cooling down the panel during production.

Where does this occur?

In many cases, blistering or folding occurs on the facade, and on the section of a building that receives the most sun-hours (south facade).

What is the risk?

Due to warming up, the blister will become increasingly bigger and thus also become more detached, so that the panel will have to be replaced.

Can it be repaired?

Depending on the size and cause, most blisters can be repaired. We have developed 2 techniques for this:

  1. Vacuum bonding technique
  2. Comprehensive damage repair by fixing, filling, spraying
