Optimal joint depth support

Practical benefits

Prevents three-point adhesion: It ensures sealants only adhere to the sides, allowing joints to expand and contract without tearing.
Water-resistant closed-cell foam: The PE material repels water and resists high mechanical stress both indoors and outdoors.
High continuous working length: With a 600 M bulk roll and 10 MM diameter, you fill extensive construction gaps smoothly.

In a nutshell

The right choise for

Achieve the ideal joint structure for caulking expansion and connection joints with the Zwaluw 210147 backer rod. This 10 mm round foam cord prevents damaging three-point adhesion, ensuring the sealant only bonds to the joint sides so it can expand and contract flexibly without tearing. Thanks to its closed-cell pe foam composition, it does not absorb water, making it a dependable choice for both indoor and outdoor projects. With a generous 600 m roll, you can fill extensive joint runs smoothly and without interruption while establishing the exact joint depth to prevent excessive sealant waste.

Product Description:

Zwaluw Backer Rod PE is a closed-cell (polyethylene) foam rod used to fill joints between building materials to make sure the joint sealant will reach its correct dimension in width and depth. Zwaluw Backer Rod PE is supplied in various diameters, Ø 6 to 50 mm.

Advantages

Avoids three-sided adhesion of sealants

Application:

Zwaluw Backer Rod PE can be used in construction and expansion joints to achieve the correct joint-dimensions and to prevent three-sided adhesion of the sealant.
Important:
Zwaluw Backer Rod PE must be used in the construction and expansion joint to achieve the correct joint dimension and to prevent three-sided adhesion of the sealant. If the depth of the joint is not sufficient enough to apply both Zwaluw Backer Rod PE and Zwaluw Sealant, then a Zwaluw Break Tape PE should be used instead of the Backer Rod PE. The Backer Rod PE also prevents three-sided adhesion of the Zwaluw Sealant.
Make sure that the width of the joint corresponds to the movement capability of the Zwaluw Sealant. In order to to calculate a correct joint dimension, please visit our website or contact Den Braven for a proper recommendation.
The joint sealant depth can be calculated by using the following formulation: Joint Depth = (Joint Width divided / 3) + 6.
Please make sure that the diameter of the Zwaluw Backer Rod is 50% larger than the gap between the two building substrates. If the joint width is 20mm the diameter of the Zwaluw Backer Rod should be Ø 30 mm.
