20mm x 200m Backer Rod

This backer rod is commonly used as a filler for wide cracks and joints in both exterior and interior settings. It provides support for sealants and helps to control the depth of the sealant application.

By controlling the depth of the sealant, the backer rod ensures optimal adhesion and flexibility. It prevents three-point adhesion, allowing for better movement and expansion of the sealant.

Yes, this backer rod is designed for both outdoor and indoor applications. Its durable polyethylene construction makes it resistant to environmental factors, ensuring longevity in various conditions.

Yes, the closed-cell structure of the backer rod allows it to be compressed easily. This feature makes it adaptable for filling various joint sizes while maintaining its shape.

The backer rod measures 20mm in diameter and comes in a length of 200 meters per roll. This size is versatile for a range of sealing projects.

No, being made from closed-cell polyethylene, this backer rod is non-absorbent. It does not retain moisture, which helps prevent mould growth and degradation over time.

The installation involves inserting the backer rod into the joint or cracks at a consistent depth before applying sealant. It should fit snugly without excessive force to ensure proper performance.

It is made from closed-cell polyethylene foam that is non-absorbent and compressible.

Backer rods are commonly used as joint fillers in construction projects such as sealing gaps in windows, doors, concrete joints, or expansion joints.

Yes, its closed-cell structure prevents water absorption effectively.

Each roll measures approximately 200 meters in length with a diameter of 20mm.

Yes, they are designed to work seamlessly with sealants or caulking materials to ensure proper joint filling.

Yes, their compressible nature allows them to adapt to curved or irregular joints easily.

Yes, they offer some insulation properties by reducing air infiltration through gaps or joints.
