At Hawleys, we supply reliable lagging designed to protect equipment, improve energy efficiency and support safer working conditions across steam, boiler and general industrial environments. Our products suit applications where heat, pressure and continuous operation demand insulation that performs day after day.
Whether you’re managing assets in a steam plant, maintaining high-temperature pipelines or upgrading heat-exposed equipment, our solutions support stable temperatures and long-term system reliability. Each product is built from durable materials engineered to handle the toughest conditions found in boiler lagging and industrial heat management.
Hawleys provides boiler lagging material that holds up under sustained heat, vibration and pressure. By using the right insulation, you reduce heat loss, improve efficiency and maintain safer working temperatures across your infrastructure.
Our products suit a wide range of applications where effective boiler pipe lagging is essential — from steam generation to high-temperature processing, power applications and general industry.
Our fibreglass rope lagging is constructed from high-quality fibreglass and designed for temperatures up to 550°C. It is ideal for sealing and insulating gaps around boiler doors, furnace doors and other high-heat enclosures where conventional seals may break down.
This rope provides dependable sealing performance, supports safe operation and offers long-lasting durability in environments where thermal stability is critical.
Fibreglass woven web tape provides strong, flexible coverage for pipes, valves and equipment operating in high-temperature environments. Its woven construction delivers excellent insulation, while its flexibility allows it to maintain a secure fit around straight sections and irregular surfaces.
With temperature resistance up to 550°C, it offers a durable wrap that holds its shape and supports long-term heat management.
Our fibreglass ladder tape is purpose-designed for high-temperature areas where expansion and movement occur. The ladder-style construction allows for flexibility and a secure wrap around uneven shapes, providing dependable insulation up to 550°C.
It’s a popular choice for engineers looking for a reliable, adaptable option for pipe and valve lagging in demanding environments.
The PTFE stem seal range is engineered for high-pressure and high-temperature applications. With pressure capability up to 140 bar and temperature resistance up to 260°C, it is ideal for valves, fittings and steam system components that need strong chemical resistance and long-term sealing performance.
Our quick wrapped expansion joint is designed to accommodate movement, reduce mechanical stress and provide insulation in high-temperature pipe systems. With temperature resistance up to 500°C, it supports thermal expansion and helps maintain alignment in critical industrial applications.
We pair decades of industry experience with trusted materials, helping you achieve stable, efficient and compliant system performance.
Explore our range of tapes, ropes, seals and high-temperature insulation materials to find the best solution for your operation. If you need support choosing the right boiler lagging material or want help selecting products for a specific application, our team is here to assist.

What is lagging in industrial applications?
Lagging is the insulation applied to pipes, boilers and valves to reduce heat loss, control surface temperature and protect personnel. It’s widely used in steam, boiler and high-temperature systems to improve efficiency and maintain safer operating conditions.
What materials are lagging products made from?
Most lagging products are made from high-grade fibreglass, chosen for its durability and temperature resistance up to 550°C. We also supply PTFE and specialised high-temperature materials for applications requiring chemical resistance or movement accommodation.
Where is fibreglass rope lagging used?
Fibreglass rope lagging is used to seal and insulate gaps around boiler doors, furnace doors, access panels and other high-heat enclosures. It withstands temperatures up to 550°C and creates a stable thermal barrier where traditional seals may fail.
When should I use fibreglass woven web tape?
Choose woven web tape when you need a strong, flexible wrap for high-temperature pipes and valves. It provides reliable insulation up to 550°C and maintains a secure fit across both straight runs and irregular surfaces.
What is fibreglass ladder tape used for?
Ladder tape is ideal for pipes, valves and components that expand and contract under heat. Its ladder-style construction allows for movement while still providing dependable insulation in high-temperature environments.
Is PTFE Stem Seal suitable for steam and boiler applications?
Yes. PTFE Stem Seal handles up to 140 bar and 260°C, making it suitable for valves, fittings and steam components that require strong chemical resistance and long-term sealing.
What does a Quick Wrapped Expansion Joint do?
A Quick Wrapped Expansion Joint absorbs movement in high-temperature pipe systems, helping prevent misalignment and reducing mechanical stress. It also provides insulation for temperatures up to 500°C.
