Pile weatherstripping comes in various sizes, shapes,and materials, Daoseal Popular Pile Weatherstrip include Zipper pile,Extrude Base Pile, Kerf Pile weatherstrip, Diamond (Square) base pile,Silicon wool pile weather, Adhesive Pile Weatherstrip etc 

Zipper Pile Weatherstrip

Zipper pile weatherstrip, also known as zip pile weatherstripping, is a type of weather seal used in windows and sliding doors to prevent air leakage and improve energy efficiency. It is characterized by its unique “zipper” design that allows for easy installation into the weatherstrip channel. Here are three key features of zipper pile weatherstrip

Extrude Base Pile Weatherstrip

Extruded base pile weatherstrip refers to a type of weatherstripping that combines a pile (or brush-like) material with an extruded base, typically made from vinyl or other synthetic materials, designed to seal gaps in windows and doors against air and water infiltration. Here are three distinctive features of extruded base pile weatherstrip:

Kerf Pile weatherstrip

Kerf pile weatherstrip refers to a specific type of weatherstripping used to seal gaps around doors and windows, enhancing energy efficiency by preventing drafts. This weatherstripping consists of a pile or dense brush material mounted on a kerfed (notched) base that can be fitted into a groove or slot—referred to as a “kerf”—cut into the door or window frame.

The pile material compresses when the door or window is closed, forming a tight seal that blocks air flow. Kerf pile weatherstripping is popular because it provides an effective seal without significantly increasing the force required to open or close the door or window. It’s also relatively easy to install and replace, making it a practical choice for both new construction and retrofit applications.

How to Choose the Right Pile Weatherstrip

Choosing the right pile weatherstrip depends on your application, frame type, sealing requirement, and installation method. Here’s a quick guide:

  • For sliding windows and doors: Use Fin Pile or Silicone Pile for improved sealing and durability.
  • For DIY or household repair: Use Self-Adhesive Pile – easy to install without tools.
  • For general-purpose aluminum or PVC frames: Wool Pile offers a budget-friendly option.
  • For custom systems or noise reduction: Zipper Pile offers dual-brush design for tighter sealing.
