Finned Weather Strip vs Regular Wool Pile Weatherstrip
Understand when to choose finned weather strip and when regular wool pile weatherstrip is enough for sliding systems.
Regular pile weatherstrip
Regular pile is a practical choice for standard dust control and common sliding window applications where the gap does not require an extra barrier.
Finned weather strip
A center fin can improve the barrier against air, dust and insects, but the fin height must fit the profile gap to avoid excessive friction.
How to decide
Compare groove width, pile height, sliding clearance and target performance. For higher barrier requirements, sample a finned structure before bulk order.
