Siliconed Wool Pile Weatherstrip (Siliconized Pile)

The pile, backing and sizes are the same as regular wool pile; the difference is a silicone finish on the PP yarn. Buyers choose it for three reasons: the sash slides with less effort, the treated yarn sheds water instead of soaking it up, and the pile keeps a cleaner surface in outdoor positions.

Siliconed pile costs more than regular pile, so it is usually specified where those benefits matter: busy sliding doors, windows facing weather, and replacement where the old strip was already siliconed.

Siliconed pile is made to the same groove-fit rules as regular pile.

Sizes are written as base width x pile height; finned sizes add the fin height. These combinations appear often in siliconed orders and are a starting point, not a stock list.

How to measure base width and pile height

If the current regular strip works and the window is not exposed, keeping regular pile is the economical choice. Switch to siliconed when users report a stiff sash or the position faces sun and rain.

Siliconed pile is common on sliding patio and balcony doors, on the outer track of sliding windows and in aluminum and UPVC systems sold into hot, wet or coastal markets. It is often combined with UV-stabilized yarn for sun-exposed positions.
