Download the full Schlegel Brush Pile Seals brochure for detailed product specifications, dimensional data, a complete colour reference chart and the brush pile selector guide covering all woven and extruded product types for aluminium, PVC-U and timber applications.
Virgin polypropylene yarn as standard
Every Schlegel brush pile seal is manufactured from virgin polypropylene (PP) yarn, not recycled material, ensuring consistent fibre density and reliable performance across the stated brush height range from 3.0 mm to 20.0 mm.
Silicone treatment for moisture, mould and mildew resistance
The polypropylene yarn in Schlegel brush pile seals is treated with silicone to resist water penetration, mould growth and mildew. This treatment maintains sealing performance in exposed external applications.
Fin configurations for higher air tightness
Optional central and lateral fin positions are available across the Fin-Seal, G3, G3-QF, Fin-Pile and Bi-Fin product series to sit at pile height or 1 mm above.
Suitable for timber, PVC-U and aluminium frame systems
The brush pile range is designed to perform across all principal fenestration frame materials. Woven base products suit surface-mount and groove-fit timber applications, while extruded base profiles are specified for machine-fitted PVC-U and aluminium lines.
Guarantee and compliance
Brush pile seals are EN 12365 compliant for specification and carry a 10-year product guarantee. Manufacture is certified to ISO 9001:2008 for quality management and ISO 14001:2004 for environmental management
Woven brush pile seals: Poly-Bond and Fin-Seal
The Poly-Bond (PB) series uses a soft multifilament polypropylene pile yarn on a woven, reinforced translucent backing, making it suitable for sliding windows, sliding doors, window coverings and furniture. An optional hot-melt adhesive backing simplifies installation without additional fixings. The Fin-Seal (FS) builds on this with one or two integrated polypropylene fins at centre position, improving air tightness across sliding window and door applications. Backing widths of 4.8 mm, 6.7 mm and 6.9 mm are standard, with brush heights from 3.0 mm to 15.0 mm in 0.5 mm increments up to 8 mm, and 1.0 mm increments beyond that.
Extruded brush pile seals: G3, G3-QF, Power-Pile, Fin-Pile and Bi-Fin
Schlegel’s extruded brush pile range is designed for fabricators using automated machine insertion, ensuring precise on-centre pile positioning for consistent fitment. Options include the silicone-treated G3, high-performance G3-QF Quadrafin, fin-free Power-Pile with optional adhesive backing, and Bi-Fin with dual lateral fins for enhanced yarn protection and superior weather sealing in demanding sliding applications.
Specialist brush pile seals: Angle-Pile, Dust-Plug, Shutter-Pile and Flex-Brush
Beyond its core sliding window and door range, Schlegel offers specialist brush pile seals for unique applications. These include Angle-Pile for insect screen channels, Dust-Plug for aluminium sliding door corners, Shutter-Pile for roller shutters, flexible coilable Flex-Brush for curved installations, and extruded Skirting-Fringe for narrow-base skirting and fringe sealing where reliable performance is essential.
