Pipe insulation

Thermal and Acoustic Protection for Piping Systems

Our category covers a wide range of products designed to protect pipes from heat loss, condensation and mechanical damage. In the Pipe insulation section you will find pre-formed foam tubes, elastomeric rubber sleeves, fiberglass and mineral wool wraps, insulation tapes, jackets and removable access covers. These items are suitable for residential plumbing, commercial heating and cooling systems, industrial process piping and HVAC installations. The selection includes materials for different temperatures, diameters and installation environments so you can specify the right solution for each project.

Types and product variants

Insulation products are available in many formats to suit installation preferences and performance needs. Common types include:

  • Pre-formed tubular insulation (foam and rubber) — fast to install on straight runs.
  • Flexible wraps and blankets (fiberglass, mineral wool) — for irregular shapes and high-temperature lines.
  • Insulation tape and self-sealing sleeves — for repairs, joints and small-diameter pipes.
  • Protective jackets and cladding — for external protection and aesthetic finishes.
  • Specialized coatings and vapour barriers — to prevent condensation and corrosion under insulation.

Where Pipe insulation is used

Applications range from domestic hot water piping to industrial steam lines. Typical use cases:

  • Residential heating and hot water systems — reduce energy loss and prevent heat transfer to surrounding structures.
  • Commercial HVAC — improve system efficiency and reduce noise.
  • Industrial process piping — maintain process temperatures and protect personnel from hot surfaces.
  • Cold systems and refrigeration — prevent condensation, freeze risks and maintain fluid temperatures.
  • Outdoor and exposed lines — protect against weather, UV and physical damage when combined with proper cladding.

How to choose pipe insulation

Choosing the right product depends on several practical and technical factors. Consider the following before purchase:

Material and temperature range

Select materials rated for your operating temperature. Elastomeric rubber performs well in refrigeration and moderate-heat applications; mineral wool and fiberglass are better for high-temperature lines.

Thickness and thermal performance

Thickness affects heat loss and condensation control. Use manufacturer U-value or R-value data to match energy-saving goals.

Moisture resistance and vapour control

For cold lines and outdoor installations, choose insulation with an integrated vapour barrier or add an external cladding to prevent moisture ingress.

Mechanical protection and maintenance access

For serviceable equipment, choose removable jackets or segmental designs that simplify inspection and repairs.

Frequently asked questions about the Pipe insulation category

What is pipe insulation and what is it used for?

Pipe insulation is a tubular insulating product made from materials like foam rubber, foamed polyethylene or mineral wool used to thermally and mechanically protect pipes. It reduces heat loss, prevents condensation and lowers noise in heating, plumbing and ventilation systems; common lengths are 1.2 m and diameters are given in mm (e.g. 48/30, 114/30).

Difference between foamed polyethylene and foam rubber pipe insulation?

Foamed polyethylene is lightweight, cost-effective and moisture resistant; foam rubber (elastomer) offers better thermal stability and elasticity, suitable for cold and refrigeration lines. Use elastomer for exposed or demanding applications and polyethylene for standard indoor plumbing.

What do markings like 48/30 mm or 114/30 mm mean on TENAPORS pipe insulation?

The marking shows outer diameter/wall thickness: e.g., 48/30 mm fits pipes around 48 mm with a 30 mm wall thickness. TENAPORS items are typically 1.2 m long; check internal pipe diameter for correct fit.

Which pipe insulation is suitable for refrigeration (K-Flex ST Frigo)?

For refrigeration lines use elastomeric K-Flex ST Frigo insulation, designed for low moisture absorption and condensation prevention. Choose sections with adhesive seams and wall thickness appropriate to the pipe diameter and temperature conditions.

What is foil-faced pipe insulation and when to choose it?

Foil-faced insulation has an aluminium facing that reflects heat and provides extra moisture and mechanical protection. Choose it for ducting and exposed runs where vapour barrier and neat appearance are required.

Is basalt pipe insulation suitable for heating systems?

Basalt (mineral wool) insulation is fire-resistant and thermally effective, making it suitable for heating systems where fire safety is important. Note basalt products may differ in shape and installation from foam tubular insulation.

What is a pipe insulation 'shell' (скорлупа) and where is it used?

A shell is a semi-cylindrical insulation segment (often mineral wool or foam) fitted around a pipe and secured with clamps or adhesive. It's used on larger external mains and where robust, layered protection is required.

What sizes of pipe insulation are available (length and diameter)?

The catalogue offers pipe insulation typically 1.2 m long with diameters listed in mm, examples include TENAPORS 18/30, 22/30, 25/30, 48/30, 54/30, 65/30, 76/30, 114/30, 159/30. Choose size to match your pipe internal diameter.

How to choose insulation wall thickness for heating and water pipes?

Wall thickness (e.g., 30 mm in 48/30) depends on pipe temperature and required thermal resistance: hotter pipes need thicker insulation; cold lines often use 10–30 mm. Also consider condensation risk and manufacturer guidance (TENAPORS).

How to install TENAPORS 1.2 m pipe insulation — glue or clamps?

TENAPORS sections usually have a longitudinal slit to fit over the pipe and are secured with clamps, tape or adhesive depending on conditions. For refrigeration lines and external runs use adhesive seams or additional clamping for reliable protection.

Can pipe insulation be used for noise reduction in ventilation?

Yes, foam rubber and basalt insulation reduce noise and vibration in ventilation ducts and pipe runs. For ventilation choose materials with sound-absorbing qualities and foil facing for enhanced sealing.
