Precision draught sealing from a woven pile base

Schlegel woven brush pile seals combine soft polypropylene multifilament yarns with a reinforced translucent woven backing to deliver reliable sealing. Independently moving fibres adapt to irregular surfaces, maintaining consistent draught protection. Manufactured to ISO 9001 standards, every seal is backed by Schlegel’s 10-year guarantee.

Standard and extended colour options for every frame finish

Standard soft multifilament yarn colours include grey and black while non-standard multifilament 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.

Key Benefits

Independent pile fibres seal against uneven surfaces

Each fibre moves separately, maintaining contact across irregular or moving frame surfaces.

Low friction for smooth sliding window and door operation

Silicone-treated PP yarn reduces surface drag when sliding

Mould, mildew and water resistance built into the yarn

PP pile treated with silicone repels moisture and resists biological growth over time.

UV stable and chemically inert for long service life

Polypropylene construction resists UV degradation and chemical exposure without deterioration.

Optional fins reduce air infiltration

Central or lateral fins on Fin-Seal and Shutter-Pile products deliver measurably tighter air sealing.

Compatible with aluminium, PVC and timber frames

Backing widths of 4.8 mm, 6.7 mm and 6.9 mm cover the kerf dimensions used across all three main frame materials.

Polypropylene pile construction: what it means in practice

All Schlegel woven brush pile seals are made from polypropylene multifilament yarn woven into a reinforced translucent backing. The PP fibre resists abrasion and static build-up, making it suited to high-cycle sliding applications. Optional silicone treatment of the yarn further reduces friction and prevents water ingress, mould and mildew accumulation over the product’s service life.

Fin options: when to specify Fin-Seal over Poly-Bond

Poly-Bond delivers dependable sealing for standard sliding windows, doors and furniture channels. Fin-Seal enhances performance with two welded clear centre fins, reducing air infiltration when compared with standard brush pile. It is ideal for improved EN 12365 draught-resistance compliance and wider sash-to-frame gaps.

How Schlegel woven pile seals are manufactured and certified

Schlegel manufactures woven brush pile seals to ISO 9001 and ISO 14001 standards, backed by a 10-year guarantee. ift Rosenheim-accredited testing at SchlegelGiesse in Hamburg provides independently verified EN 12365 performance data, supporting reliable window and door CE marking compliance.
