Product Description:

Zwaluw Backer Rod PU is a round open (polyurethane) 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 PU is supplied in various diameters, Ø 6 to 50 mm.

Advantages

Avoids three-sided adhesion of sealants

Application:

Zwaluw Backer Rod PU 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 PU 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 PU and Zwaluw Sealant, then a Zwaluw Break Tape should be used instead of the Backer Rod. The Zwaluw Break Tape 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 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 20 mm the diameter of the Zwaluw Backer Rod should be Ø 30 mm.
