Premium Wrapped PU Foam Weatherstripping

The product features high-performance Wrapped PU Foam Sealing Strips (commonly known in the industry as Q-Lon style foam seals or Kerf-inserted weatherstripping). It is a top-tier sealing solution engineered specifically for modern doors and windows, combining a highly resilient foam core with a protective, wear-resistant outer skin.

Product Specifications & Terminology

Names: Wrapped Foam Weatherstrip, PU Foam Sealing Strip, Kerf Slot Door Seal, Q-Lon Foam Seal.

Material Composition:Core: Polyurethane (PU) foam.

Outer Skin: Polyethylene (PE) film / TPE embossed film.

Insert Base: Rigid Polypropylene (PP) or PVC fish-bone barb.

Key Applications

Residential Doors: Perfect for wooden doors, security entry doors, and interior room doors.

Window Systems: Widely used in casement windows, sliding windows, and thermal break aluminum profiles.

Furniture & Cabinets: Applied in high-end wardrobes and acoustic enclosures requiring dust and sound isolation.

Outstanding Advantages

Excellent Compression Recovery

The polyurethane foam core provides superior rebound capability. It recovers its original shape quickly even after years of continuous compression, preventing gaps from forming.

Superior Soundproofing

The porous interior structure of the foam acts as an acoustic dampener, effectively absorbing noise and creating a quieter indoor environment.

Highly Durable Outer Layer

The embossed PE film wrapping protects the inner foam against friction, tearing, and UV degradation. It ensures smooth opening and closing of doors without sticking.

Weather & Temperature Resistance

It remains flexible across a wide temperature range, resisting cracking, hardening, or aging in extreme cold or scorching heat.

Effortless Installation

Featuring a rigid barbed insert base, the strip can be pushed directly into pre-cut slots (kerfs) manually without requiring glue, staples, or specialized tools.
