Product description

Backing and sealing:
- expansion joints in ATLAS 100 and ATLAS 150 eaves systems for terraces and balconies.
- construction joints prior to application of sealing coatings – e.g. thermal insulation, windows and doors assembling, execution of expansion joints in floors and walls, etc.

Main properties

  • flexible
  • resistant to ageing
  • non-absorbent
  • easy to install

Main parameters

  • temperature resistance: from -40°C to +95°C
  • absorption capacity: non-absorbent due to closed-cell structure

USE

Go top
Backing and sealing:
- expansion joints in ATLAS 100 and ATLAS 150 eaves systems for terraces and balconies.
- construction joints prior to application of sealing coatings – e.g. thermal insulation, windows and doors assembling, execution of expansion joints in floors and walls, etc.
Forms sufficiently strong base for the material sealing the joint, e.g. silicone.

PROPERTIES

Go top
Flexible – easily adjustable to the shape of the joint.
Resistant to ageing – does not deteriorate under changeable weather conditions when closed in the expansion joint sealed with silicone or other sealant; resistant to wide range of chemicals.
With closed-cell structure – impervious to water and water vapour.
Reduces the amount of material needed to fill and seal the joint.

Supports the sealants used in the expansion joint.

very good
Density
30-40 kg/m³, ASTM D 1667
Temperature resistance:
from -40°C to +95°C
Absorbability
non-absorbent due to closed-cell structure
Temperature during work
from -20°C to +40°C

GENERAL GUIDELINES

Go top
The diameter of the backer rod should be approx. 25% larger than the width of the joint to be filled – once installed in the joint, it should be compressed and should not move during the sealant application. The joint should be cleaned of loose elements prior to the installation of the backer rod. Press the rod into the joint using a blunt, rounded tool and place at expected depth, so the sealant can keep its appropriate thickness. Avoid stretching or compressing the rod lengthwise during the installation.
Once installed, the rod should not contact the bed of the joint.

IMPORTANT ADDITIONAL INFORMATION

Go top
• Store the backer rod in dry conditions.
• Any damage to the backer rod surface may cause the sealant bonding and disturb the uniform distribution of stress.
