Flexi Foam Tapes

Backer Foam Rod (also called Backer Rod) is a flexible, closed-cell polyethylene (PE) foam rod used as a backing material in construction and sealing applications. It is lightweight, compressible, and non-absorbent, making it ideal for filling gaps before applying sealants.

Key Features:

• Made from closed-cell PE foam

• Water-resistant & non-absorbent

• Highly compressible and flexible

• Provides uniform depth control for sealants

• Compatible with silicone, polyurethane, and acrylic sealants

• Available in diameters from 6mm to 50mm (or as required)

• Used as a filler in expansion joints, construction joints, and control joints.

• Ensures correct sealant depth for better performance and durability.

• Acts as a backing before applying sealant in gaps around:

  • Windows & doors

  • Aluminum or UPVC frames

  • Curtain walls

  • Concrete gaps and wall joints

• Reduces the quantity of sealant needed by filling the majority of the gap.

• Helps maintain an ideal hourglass shape of the sealant.

• Supports waterproofing systems by filling joints in flooring, terraces, and facades.

• Provides minor thermal and acoustic insulation.

• Used in bridges, highways, airport runways, and large concrete structures to fill expansion gaps before sealing.

PE Foam Backer Rod is a lightweight, flexible, and compressible Expanded Polyethylene (EPE) foam rod used as a backing material for sealants in construction, glazing, and panel applications. It helps control sealant depth, improve joint performance, and prevent three-sided adhesion.

Key Features

• Closed-cell EPE foam with very low water absorption

• Flexible and compressible for easy installation

• Acts as a bond breaker to optimize sealant performance

• Compatible with most sealants (silicone, polyurethane, etc.)

• Cost-effective and easy to handle
