Filler, Joint

Definition

A Joint Filler is a compressible material used to fill a joint to prevent the infiltration of debris and provide support for sealants.

Purpose

The purpose of a Joint Filler is to maintain the integrity of joints in construction by filling gaps and providing a stable base for sealants, preventing debris infiltration, and accommodating movement.

Examples of Use

• Concrete Pavements: Filling expansion joints to allow for thermal expansion and contraction.
• Building Facades: Using joint fillers to seal gaps between panels or sections.
• Interior Walls: Filling joints between drywall panels before applying sealant or finishing materials.

Related Terms

• Sealant: A material used to block the passage of fluids through the surface or joints or openings in materials.
• Expansion Joint: A joint that allows for movement caused by thermal expansion and contraction.
• Backer Rod: A foam rod used to fill deep joints, reducing the amount of sealant needed.

Notes

• Joint fillers come in various materials, including foam, rubber, and cork, each suited to different applications.
• Proper installation is crucial to ensure the effectiveness and longevity of the joint filler and sealant system.
