EPE sealing cord is a modern insulation material made of expanded polyethylene. It is widely used in construction, engineering systems installation, and renovation work. The primary purpose of the material is sealing joints, expansion gaps, and interfaces between various structures.
Due to its closed-cell structure, this material absorbs virtually no moisture, possesses low thermal conductivity, and retains its properties over a long service life. This is precisely why expanded polyethylene cords and products based on foamed polymers are actively used in both residential and industrial construction.
Where is the Sealing Cord Applied?
EPE insulation cord is utilized in various areas of construction and installation where reliable sealing, thermal insulation, and joint protection against external factors are required. It is most commonly used for filling expansion and interpanel joints in concrete structures, preparing joints before applying sealants, and installing window and door units.
The material is in high demand for facades, roofing systems, foundations, and utilities. Thanks to its resistance to moisture and temperature fluctuations, the polypropylene cord effectively prevents water penetration, the formation of thermal bridges, and premature degradation of construction joints.
Furthermore, expanded polyethylene sealing cord is used in the installation of pipelines, ventilation ducts, air conditioning systems, and other engineering networks. It helps compensate for thermal expansion of materials, reduces heat loss, and enhances structural durability. Its versatility, ease of installation, and long service life make this material highly sought after in both private construction and large industrial facilities.
Selecting the Cord Diameter
Insulation efficiency directly depends on the correct choice of material thickness. Please note: the diameter of the EPE cord should be 20–30% larger than the actual width of the insulated gap to ensure a tight, friction-fit position.
- Small diameters (6–8 mm). The optimal solution for filling, leveling, and sealing expansion joints in concrete and industrial floors, as well as narrow technological gaps.
- Medium diameters (10–15 mm). Used for sealing joints when cladding walls with lining boards (to compensate for thermal expansion), sealing connections during plumbing installation, and insulating installation joints around door frames and window units.
- Large diameters (20–60 mm). Used for comprehensive insulation and waterproofing of interpanel joints (including external walls of residential and industrial buildings), insulating bridge joints, and as shaping elements in upholstered furniture manufacturing.
Advantages of EPE Cords
A high-quality EPE cord offers a number of important advantages:
- eliminates three-point adhesion of the building sealant (to the back wall of the joint), preserving its elasticity and preventing tears during building shrinkage;
- low thermal conductivity;
- closed pores do not absorb moisture, protecting structures from dampness, mold, and mildew;
- light weight;
- ease of installation;
- significantly reduces the consumption of expensive polyurethane or silicone sealing mastics;
- long service life;
- environmental safety.
Thanks to these characteristics, the polyethylene cord is successfully used both indoors and at outdoor sites.
