Grey Wool Pile Weatherstrip for Sliding Doors & Windows
High-density grey pile weatherstrip designed for sliding doors, windows, wardrobes and track systems requiring low-friction dust and draft control.
How to Size Wool Pile Weatherstrip
Match the backing width to the receiving groove and choose a pile height that maintains light contact across the operating gap. Too little contact can leave a leakage path; excessive interference can increase sliding resistance or deform the pile.
Measure the groove width and depth, minimum and maximum gap, direction of movement and available insertion clearance. Confirm whether a center fin or adhesive-backed construction is required.
Dimensions to Confirm
| Input | What to measure |
|---|---|
| Backing width | Inside width of the receiving groove or mounting surface |
| Pile height | Distance from backing to fiber tip before installation |
| Working gap | Minimum and maximum clearance during movement |
| Contact | Desired fiber interference without excessive drag |
| Construction | Standard pile, center fin or adhesive-backed option |
Choose Pile Height, Backing and Fin by Application
Use the operating gap as the starting point, then confirm groove fit and sliding force on the actual frame. Final dimensions should be approved from a sample rather than selected from pile height alone.
| Application condition | Recommended review | Why it matters |
|---|---|---|
| Stable, narrow sliding gap | Standard pile with light, continuous fiber contact | Controls dust and drafts without unnecessary drag |
| Gap changes along the track | Taller or denser pile after checking closing force | Maintains coverage across dimensional variation |
| Higher air or water-control requirement | Center-fin construction and matched compression | The fin adds a more defined barrier behind the fibers |
| No receiving groove | Adhesive-backed brush strip and clean mounting surface | Provides an alternative when groove insertion is unavailable |
| High-cycle sliding door or window | Prototype test for friction, wear and pile recovery | Confirms smooth movement over repeated cycles |
Low-Friction Sealing for Sliding Systems
Fine pile fibers flex during movement and return to cover variable clearances. The strip helps reduce dust, drafts, light leakage and rattling while allowing sliding panels to operate smoothly.
Typical Applications
- Aluminum sliding doors and windows
- Wardrobe and closet doors
- Screen and insect-mesh systems
- Cabinet and partition tracks

Smooth Movement with Consistent Coverage
Dense Flexible Pile
Fine fibers adapt to irregular gaps while maintaining light contact.
Low Sliding Resistance
Brush contact supports sealing without heavy compression.
Optional Center Fin
A fin option can improve air and water control for suitable systems.
Custom Dimensions
Backing width, pile height, density and roll length can be matched.
Checks Before Bulk Production
Install the trial strip in the real groove and evaluate it through the full opening and closing travel.
- Backing enters the groove without twisting, buckling or excessive looseness
- Pile maintains continuous contact at both minimum and maximum gaps
- Sliding force remains acceptable through the full track
- Fibers recover after compression and do not remain permanently flattened
- Center fin, adhesive and color match the approved specification when required

Frequently Asked Questions
Pile height should slightly exceed the working gap so the fibers maintain contact without creating excessive sliding resistance.
Yes. Backing width, pile height, density, fin, color, adhesive and roll length can be customized.
Available stock or trial samples can be discussed after the profile, dimensions and application are confirmed.
