The Types segmentation classifies sealing strips into material‑based sub‑categories: Compression (foam) seals, Brush (fiberglass) seals, Elastomeric strips (including EPDM rubber, silicone, and PVC), and Metal‑backed profiles. Compression seals, typically made from low‑density polyurethane, dominate due to low cost and ease of installation, contributing the largest share of the product mix. Brush seals, characterized by flexible bristles, are favored in high‑traffic commercial doors for their wear resistance, capturing a notable portion of the commercial slice. Elastomeric strips—especially EPDM and silicone—offer superior temperature stability and chemical resistance, making them the preferred choice in industrial settings and premium residential projects. Metal‑backed profiles, integrating aluminum or steel carriers, provide structural rigidity for large‑scale door assemblies, supporting niche applications such as fire‑rated doors. Each type’s market contribution aligns with performance requirements, cost considerations, and regulatory drivers, collectively defining the market taxonomy for sealing strips.
