Advanced piping systems and technical insulation for plumbing, ventilation, heating and cooling installations in over 45 countries.
Thermaflex is a global leader in the field of technical insulation for plumbing, heating, cooling and ventilation with over 35 years experience in the industry.
Thermaflex insulation products are made from environmentally friendly and fully recyclable materials; mainly sourced from the Polyolefin family of resins, including Polybutene-1 (PB-1).
Due to its state-of-the-art production foam process, Thermaflex foams are even, fine grained and with a closed cellular structure. This process delivers a product which can be used within a temperature range from -80°C up to +95°C for tube insulation as well as for sheets and other flexible products.
In addition, Thermaflex products have excellent water vapour diffusion resistance, are non-toxic and comply with building standards, requirements and restrictions in most countries.
The company offers a full range of products for insulation-based applications including: chilling, refrigeration, air-conditioning, sanitary, water-services as well as for central heating systems.
Product innovation and techniques are constantly being upgraded to meet ever-increasing building requirements, changing market demands and to simplify the installation process.
Thermaflex currently has production companies and sales offices in Europe, Russia, Asia and Latin America. Our advanced piping systems are available in over 45 countries.
Flexalen 600 was the first fully certified flexible pre-insulated pipe system to be available worldwide.
In 2003 Thermaflex introduced an important product innovation developed in co-operation with the Dutch Energy Provider NUON. The result was the new compact Flexalen 600 system made through new advances in production technology. Flexalen pipe systems are highly corrosion-resistant, pressure and temperature resistant (up to 95°C and 8 bar).
Due to the flexible, closed cell, superior quality polyolefin foam, optimal levels of insulation can be achieved. Both pipes and fittings are made from Polybutene-1 and offer safe and homogeneously welded connections. Because PB-1 provides high flexibility, installation is quick, easy and cost-efficient.
Also, with a product lifetime of over 40 years and a clear cost advantage compared to steel; Flexalen pipe systems made from PB-1 and other high quality Polyolefins provide a number of significant benefits.
Polybutene-1 (PB-1) is the Thermaflex preferred raw material for these piping solutions and the material has delivered excellent long-term results in District Energy applications for over 30 years.
Thermaflex piping systems from PB-1 also offer convenience for constructors in the field because it can be coiled for easy transportation and storage. In addition, Flexalen systems are up to five times faster to install than traditional materials and the inherent pipe flexibility allows for curvature around trees and plants, helping to protect the environment.
Flexalen 600 was the first fully certified flexible pre-insulated pipe system to be available worldwide. KIWA has carried out a complete test program according to BRL (5609 Part A and BRL 17401 Part A) standards.
Thermaflex product applications
Plumbing & Heating
Energy saving systems for the internal distribution of hot & cold water including pipe insulation (FR, AC, Thermacompact) and pre-insulated pipes (Flexalen 60) or a combination of PB pipes and Polyolefin insulation.
Cooling & Air-conditioning
For the insulation of air-ducts or chilled water pipes Thermaflex offers a wide range of tube and sheet insulation (FR, AC). Pre-insulated pipe solutions (Flexalen) e.g. for split airconditioning are also offered.
For the efficient distribution of District Energy (heating and cooling) Thermaflex offers flexible pre-insulated pipe solutions (Flexalen) in coils up to 200m long.

Industry & Protection
For the thermal insulation of all kinds of pipe-work, ducts and surfaces as well as the protection of sensitive products during transport Thermaflex offers a variety of foamed products (tubes, sheets, profiles) also designed according to special needs.
Sustainability is good business
Our operating philosophy is: minimise the waste of energy – maximise the use of renewables.
Thermaflex specialises in extruding environmentally-friendly, recyclable polyolefin plastics into pipes and insulating materials. In line with our energy and environment saving core values, we strive to achieve full sustainability. Therefore, we place a high priority on efficient and renewable energy sources for our own production processes.
We only select (raw) materials for our products that meet the highest health and safety standards and are both energy efficient and recyclable. In order to be sustainable, the long life-cycles and recyclability of the materials we use, including Polybutene-1 (PB-1), provide significant benefits to the end-user.
The development of CFC-free insulation marked a milestone in Thermaflex production in 1990 – long before European legislation banned these propellants.
At Thermaflex, the focus is firmly on energy-saving product solutions such as highly efficient pipe insulation for use in building services and thermally insulated pipe systems for local heating networks. Thermaflex-Flexalen is proud to be a Climate Alliance company. By becoming a member of Klimabündnis Österreich, the Austrian Climate Alliance network, Thermaflex is highlighting the key role environmental compatibility plays in our operating philosophy and supporting climate initiatives.
Certifications and standards
With its Cradle to Cradle Silver Certification, Flexalen 600 is the only pre-insulated pipe in the market. It therefore represents the most sustainable choice for thermal energy distribution.
