UV stable and chemically inert for long service life
Polypropylene construction resists UV degradation and chemical exposure without deterioration.
Backed by Schlegel's 10-year product guarantee
Every Flex-Brush coilable pile seal carries Schlegel's 10-year guarantee, supported by ISO 9001 and ISO 14001 certified manufacturing.
How coilable brush pile seals differ from standard extruded pile seals
Standard extruded brush pile seals are available in rigid and semi-rigid profiles for straight window and door channels. Schlegel Flex-Brush features a flexible, coilable extruded base that follows curved geometries, making it ideal for revolving doors, circular openings, escalators and garage door perimeter sealing applications.
Where Flex-Brush coilable pile seals are specified
Schlegel Flex-Brush is specified for commercial, industrial and architectural sealing applications. Its flexible design makes it ideal for revolving door perimeters, escalator side skirt panels, and garage or industrial doors, delivering reliable sealing wherever curved, irregular or complex track paths prevent the use of rigid brush pile profiles.
Polypropylene pile: the material behind the seal's performance
All Schlegel brush pile seals, including Flex-Brush, are made from virgin polypropylene yarn. PP pile fibres move independently, sealing effectively against moving surfaces and uneven contact faces. The material carries excellent resistance to abrasion and static build-up, and when silicone-treated, actively repels water, mould and mildew across the product’s service life.
