Industrial and Commercial Pipe Insulation Supplies

Welcome to Pirouz Ltd, your trusted UK supplier of high-performance pipe insulation engineered for demanding industrial refrigeration, cold storage, and commercial HVAC applications. Selecting the right thermal lagging is critical for maintaining precise system temperatures, preventing surface condensation, and reducing energy loss across extensive pipe networks. We maintain substantial UK stock holdings of elastomeric foam and mineral wool lagging, offering trade professionals reliable materials that meet rigorous British and European standards.

Whether you are outfitting a large distribution warehouse, upgrading a commercial cold room, or maintaining industrial process cooling lines, our product range delivers proven thermal efficiency. As specialists in the refrigeration sector, we understand that downtime is costly. That is why we provide rapid dispatch from our Harlow distribution centre alongside competitive trade pricing to keep your projects on schedule and within budget.

Technical Specifications and Material Options

Our pipe lagging inventory is selected specifically to withstand the harsh operating conditions found in commercial and industrial environments. Correct material specification ensures long term reliability, preventing thermal bridging and protecting pipework from corrosion under insulation.

Elastomeric Nitrile Rubber Insulation

Flexible closed cell elastomeric foam is the industry standard for refrigeration and chilled water systems. The built in water vapour barrier prevents moisture migration, which is the primary cause of pipe corrosion and efficiency loss in sub zero applications.

• Thermal conductivity (lambda value): 0.033 W/(m·K) to 0.038 W/(m·K) at mean temperatures of 0°C.
• Operating temperature range: minus 50°C to plus 105°C, making it suitable for both suction and liquid lines.
• Fire performance: Tested to BS EN 13501-1, achieving Euroclass ratings for enhanced safety on site.
• Structure: Highly flexible closed cell matrix that resists microbial growth and mechanical damage.

Available Wall Thicknesses and Diameters

To accommodate various pipe sizes and operating temperatures, we stock insulation profiles in standard wall thicknesses ranging from 9mm up to 50mm. Inner diameters are available to fit copper, carbon steel, and stainless steel pipework from 15mm up to 168mm OD. Pre-slit sections with factory applied self-seal adhesive strips are available across popular sizes to accelerate on-site installation times.

Applications in Commercial Refrigeration and HVAC

Effective thermal lagging plays a central role in overall facility performance. When combined with proper cold room panels and doors, high quality pipe insulation helps facility managers achieve maximum energy efficiency. You can read more about overall facility optimization by exploring our guide on boosting efficiency and key strategies for UK commercial cold storage.

Key applications for our thermal lagging products include:

• Commercial refrigeration suction and discharge lines.
• Chilled water distribution pipework in air conditioning systems.
• Low temperature process piping in food manufacturing and pharmaceutical plants.
• Ammonia and glycol secondary cooling loops.

Frequently Asked Questions

What thickness of pipe insulation do I need for a refrigeration suction line?

The required thickness depends on the operating temperature of the fluid, ambient air temperature, and relative humidity. Thicker walls are necessary for lower temperatures to prevent surface condensation and maintain thermal efficiency. Contact our technical team with your operating parameters, and we will calculate the precise specification required.

Do you supply adhesives and accessories alongside the lagging?

Yes, we stock a comprehensive range of system accessories including contact adhesives, joint sealing tape, protective aluminium cladding, and pipe support inserts designed to prevent thermal bridging at hanger locations.

How quickly can I receive my order in the UK?

Standard stock items are typically dispatched for next day or 48 hour delivery across mainland UK. For urgent site requirements, expedited delivery options can be arranged through our customer service desk.
