PRODUCT DESCRIPTION
ISO-ZELL PE-CORD is a round seal, which fulfils the requirements of the DIN 18540 for backfill material on expanding joints. It consists of closed cellular polyethylene foam and is suitable for sealing against drafts and heat loss.
ISO-ZELL PE-CORD provides a reliable backfill on building joints and is characterised through its excellent compatibility with all standard sealing materials. Used as a backing support for sealants, 3-sided adhesion can be effectively eliminated.
PRODUCT ADVANTAGES
- Fulfils the requirements of the DIN 18540 for backfill material on expanding joints
- Suitable for damp joints
- Water and moisture resistant
- Also suitable with porous materials
- Minimises the joint depth and eliminates the 3-sided adhesion on back filled sealants (silicone, acrylic, PU, etc.)
- Compatible with all standard sealants (silicon, acryl, etc.)
- Elastic, flexible
- Free from softeners
- Ageing resistant
Applications
ISO-ZELL PE-CORD is particularly suitable for plugging and as backfill material for sound absorption and sealing of:
- Cavity filling
- Construction and variable joints
- Joint sealant
- U-Profile glass sealing
- Due to its water-resistant surface ISO-ZELL PE-CORD can be used in both interior and exterior areas as backfill material. The neutral product properties and the closed cellular surface also make it suitable to use with porous materials.

Preparation
Compress the ISO-ZELL PE-CORD and insert in to the joint or cavity. Push it in until the desired joint depth is reached. For the joint to conform to DIN 15.540, avoid stretching the cord when installing it and ensure any butt joints meet exactly. To avoid damage to the material it should not be installed using pointed instruments.
ISO-ZELL PUR-CORD
- Characteristics: ISO-ZELL PUR-CORD is an open cellular polyurethane foam
- Application: ISO-ZELL PUR-CORD is ideal as backfill material in internal joints which are not exposed to moisture.
- Form of delivery: 15 – 50 mm diameter: 1 m long pieces
