Woolpile (4.8mm x 6mm)—also known as weather stripping, brush seal, or siliconized brush pile—is an essential sealing component designed specifically for the sliding tracks and interlocking profiles of uPVC windows and doors.
It plays a critical role in preventing air leakage, dust infiltration, water penetration, and rattling noises when sashes bypass each other.
When sourcing woolpile for fabrication or replacement, ensure it meets these premium structural standards:
Siliconized Fibers: Look for pile labeled as “siliconized.” This treatment coats the fibers to repel water, preventing the brush from absorbing moisture, rotting, or freezing during heavy monsoons or winters.
Fin Weather Stripping (Optional Upgrade): Some high-performance variations feature a thin, solid plastic fin running down the center of the brush fibers. This fin acts as an absolute physical barrier against heavy drafts and driving rain.
UV Stabilization: Because the pile faces direct sunlight along the window tracks, it must be UV-treated to prevent the fibers from turning brittle, crumbling, and shedding over time.
