Our special adhesive tapes seal holes and gaps to ensure that no PU-foam leaks out.

Excellent thermal efficiency is important for refrigerated trucks and recreational vehicles to be fuel-efficient, cost-efficient and reliable. To insulate vehicle bodies’, manufacturers spray, pour or inject foam into wall and roof panels.

As the foam expands, the air displaces and escapes through a number of ventilation holes. Our Venting tape tesa® 4580 is a single-sided white non-woven tape with a selective adhesive that is used to cover these holes whilst being air permeable to ensure a perfect foaming result.
