Independent pile fibres seal against uneven surfaces
Each fibre moves separately, maintaining contact across irregular or moving frame surfaces.
Search by SKU code or category to find the right seal for your application.
Extruded brush pile seals combine a rigid carrier profile with flexible polypropylene pile fibres that move independently to seal against moving elements and uneven surfaces. Used across fenestration, window covering and interior applications, they deliver reliable draught, dust and water exclusion for the service life of the frame.
Standard pile colours are grey and black while non-standard colours, available subject to minimum order quantities, include white, brown and beige. Contact our team for lead times and minimum order requirements on non-standard colours.
