Products / Finned Weatherstrip

Koz İplik Finned Weatherstrip, developed for sliding systems, provides superior sealing performance during dynamic structural movements. Its patented fin design distributes pressure 40% more evenly than traditional pile weatherstrips, yielding excellent insulation in glass balcony systems and sliding windows.


Thermoplastic polyurethane (TPU) fins of various heights are integrated onto a 0.70 mm PP base. These fins have a low friction coefficient (μ < 0.15), which minimizes energy loss during movement. This product withstands heavy-load conditions with a compressive strength of 1600 N/mm², while its PP fibers (at 5000 filaments/cm² density) neutralize dust and water infiltration. Favored in the automotive industry for vehicle glass seals and in industrial door systems, this solution has successfully passed durability tests exceeding 100,000 motion cycles. 


For custom fin heights or angle modifications for your special projects, please consult our technical advisors.
