QL 3013

Q-LON offers superior quality compared to other seals thanks to its unique composite design, outstanding technical performance—including excellent compression recovery, low moisture and air permeability, and effective sound reduction—as well as its exceptional longevity and durability.

Polyurethane (PU) foam core, Polyethylene (PE) film and Polypropylene (PP) insert  

Guaranteed for 10 years . Lifecycle typically longer – example user cases of 25-30 years

Unlike some other seals, Q-LON works by absorbing moisture into its central foam core, preventing it from travelling beyond the gasket. When the gasket is compressed, the absorbed moisture is naturally released. For Q-LON to absorb moisture, doors and windows must be left open.
