Polyethylene closed-cell insulation tubes are a versatile and efficient solution for thermal insulation in building services and industrial systems. Designed to limit heat transfer and protect pipelines and equipment, they combine thermal efficiency, mechanical strength, and ease of installation in a single material.

Thanks to their closed-cell structure, these insulation tubes help reduce heat loss in heating systems and limit unwanted heat gain in cold water, ventilation, and air conditioning applications. The sealed cellular matrix also provides resistance to moisture absorption, contributing to long-term performance and system protection.

Polyethylene insulation tubes are widely used for heating networks, hot and cold water supply lines, ventilation systems, air conditioning installations, and technical equipment. Their ability to perform reliably across a broad temperature range makes them suitable for residential, commercial, and industrial environments.

In addition to thermal performance, polyethylene insulation offers excellent mechanical strength. This makes it particularly suitable for underfloor installations and technical areas where durability and dimensional stability are essential. Tear resistance and practical handling characteristics further support fast and efficient on-site installation.

K-FLEX plays a strategic role in this field by developing polyethylene insulation technologies engineered to meet real installation needs and long-term performance expectations. With a wide range of formats, diameters, and thicknesses, K-FLEX supports efficient insulation of heating, cooling, ventilation, and equipment systems across diverse applications.

By combining thermal efficiency, mechanical durability, and installation practicality, polyethylene closed-cell insulation tubes contribute to energy savings, system protection, and improved overall building performance.
