Types of Insulation for Pipes Explained.
Uninsulated pipes can lead to wasted energy, increased costs, and even system failures due to freezing or condensation buildup. Pipe insulation is an essential part of industrial, commercial, and residential projects. It helps to prevent heat loss, reduce condensation, and protect pipes from freezing. The right insulation improves energy efficiency, extends the lifespan of pipework, and enhances overall system performance.
From PVC foam to polyurethane, fibreglass, and more, different insulation materials offer distinct advantages depending on the application. Below, we take a closer look at the different types of pipe insulation available and how our materials can offer effective solutions.
What is Pipe Insulation?
Pipe insulation, also known as pipe lagging, involves wrapping pipes with insulating materials to control temperature, reduce energy loss, and prevent damage. It is commonly used in plumbing, HVAC systems, industrial applications, and refrigeration to keep systems running smoothly and efficiently.
Benefits of Pipe Lagging
Reduces heat loss.
Improves energy efficiency and lowers heating costs.
Prevents condensation.
Helps to minimise moisture buildup and corrosion.
Protects against freezing.
Stops pipes from bursting in cold temperatures.
Enhances safety.
Reduces the risk of burns from hot pipes.
Dampens noise.
Lowers sound transmission through pipes.
Types of Insulation for Pipes
Selecting the right insulation material for pipes can make a significant difference in energy efficiency, system longevity, and overall performance. Each type of insulation has its own benefits, whether it's moisture resistance, heat retention, or flexibility. Below, we explore some of the most common types of pipe insulation.
PVC Foam
PVC foam insulation is valued for its flexibility, water resistance, and durability. It is particularly useful in areas where moisture control is a priority, such as pipe insulation for residential properties such as hot and cold water pipes. Its closed-cell structure prevents water ingress, helping to protect pipes from corrosion and damage over time.
Fibreglass
Fibreglass insulation is widely used for high-temperature applications. It consists of fine glass fibres that provide strong thermal resistance. This makes it a popular choice in industrial and commercial settings where temperature stability is essential. However, fibreglass requires a protective covering to prevent skin irritation caused by the fine glass fibres, which can become airborne during installation and maintenance.
Expanded Polyethylene (PE) Foam
Lightweight and cost-effective, expanded polyethylene foam offers superior thermal insulation. It is widely used in domestic and commercial plumbing due to its flexibility and resistance to water absorption. PE foam is easy to install, making it a convenient choice for many pipe lagging applications.
Polyethylene Foam
Polyethylene foam insulation is durable, water-resistant, and provides strong protection for pipes. We offer both chemically and physically cross-linked PE foam options:
Chemically Cross-Linked PE Foam.
Our chemically cross-linked PE foam is designed for superior thermal insulation and durability. Its closed-cell structure minimises moisture absorption, ensuring long-lasting performance. With a density of 25-45 kg/m³, it effectively reduces energy loss while maintaining stable pipe temperatures. Its fine-cell composition enhances mechanical strength and chemical resistance, making it ideal for industrial applications.
Physically Cross-Linked Foam.
Our physically cross-linked PE foam is engineered for high mechanical strength and thermal efficiency. Its fine, closed-cell structure limits moisture absorption, preventing condensation buildup and temperature fluctuations. With a density of 33-67 Kg/m³, it offers reliable insulation for pipes in industrial and commercial settings.
Polystyrene
Polystyrene insulation is commonly used for underground pipes and chilled water systems. It provides high compressive strength and excellent thermal resistance, making it a dependable choice for maintaining consistent temperatures in extreme conditions.
Rubber
Rubber insulation, such as nitrile rubber, is highly flexible and provides excellent thermal and moisture resistance. It also offers resistance to mechanical damage and compression, ensuring effective insulation even in high-traffic areas or tight spaces where pipes may be subject to movement or impact.
Mineral Wool
Mineral wool insulation is made from natural or synthetic fibres and is known for its fire-resistant properties. It is widely used in industrial pipe applications where high-temperature resistance is necessary. Additionally, it offers effective soundproofing and reduces noise transmission from pipes.
Polyurethane
Polyurethane foam insulation is highly efficient and commonly found in refrigeration and HVAC systems. Our non-porous film pu coat polyurethane foam has a protective film layer that prevents water ingress, making it highly effective in humid environments where condensation can be an issue. This non-porous coating also enhances resistance to abrasion and mechanical stress, providing added protection against external damage. With strong thermal stability, it reduces heat loss and improves energy efficiency in HVAC and industrial piping systems. Its robust composition ensures long-lasting performance, making it a dependable choice for demanding insulation applications.
Nitrile/ PVC Sponge
Our nitrile/PVC sponge has a density of 70 Kg/m3. This density enhances compression resistance, making it suitable for high-pressure systems where structural integrity is essential. Its insulating properties help regulate pipe temperatures while also minimising vibration and noise. Additionally, its closed-cell composition ensures long-lasting thermal performance, improving overall energy efficiency in industrial applications.
