Closed-Cell vs Open-Cell Pipe Insulation
What Is the Difference?Pipe insulation materials fall into two broad categories based on their cellular structure: closed-cell and open-cell. The distinction is fundamental to condensation control and determines which applications each material is suitable for.Closed-cell insulation has a cellular structure in which each cell is sealed and does not connect to adjacent cells. This structure prevents moisture vapour from passing through the material, giving it a very low water vapour permeability. Closed-cell materials include elastomeric foam (Armaflex EVO, K-Flex ST), polyisocyanurate (PIR) and extruded polystyrene (XPS).Open-cell insulation has a cellular... Read more...
How to Repair Failed Vapour Barriers
When Vapour Barrier Repair Is NeededA vapour barrier failure on cold or chilled water pipework is not a cosmetic issue — it is a functional failure that will result in condensation, saturated insulation and eventual pipe corrosion if left unaddressed. Early identification and correct repair prevents the progressive deterioration that makes replacement of entire pipe runs necessary.Vapour barrier failures fall into three categories: installation defects (unglued joints, uninsulated fittings), mechanical damage (punctures, cuts, compression), and age-related degradation (UV breakdown on outdoor sections, adhesive failure on older installations).This article is part... Read more...
Why Pipe Insulation Gets Wet
The Most Common Question on Cold PipeworkWet or damp pipe insulation is one of the most frequently reported problems on cold and chilled water systems. It is almost always caused by one of three things: condensation forming within the insulation system, moisture ingress through a failed vapour barrier, or water ingress from an external source such as a roof leak or pipe joint failure.Identifying the correct cause is essential before attempting a repair, because the remediation approach differs significantly depending on the source of the moisture.This article is part of...

Dew Point Explained for Pipe Insulation
What Is Dew Point?Dew point is the temperature at which moisture in the air begins to condense into liquid water. When a surface — such as a cold pipe or the outer face of pipe insulation — falls below the dew point temperature of the surrounding air, condensation forms.For pipe insulation, dew point is not an abstract concept. It is the critical threshold that determines whether your insulation system will perform correctly or fail prematurely.Why Dew Point Matters for Pipe InsulationOn cold pipework — including chilled water systems, cold water... Read more...
How to Prevent Condensation on Cold Pipes
Why Cold Pipes SweatCondensation on cold pipes is not a sign of a leaking pipe — it is atmospheric moisture condensing on a surface that has fallen below the dew point of the surrounding air. The colder the pipe and the more humid the environment, the greater the condensation risk.Left unaddressed, condensation causes corrosion, saturates building fabric, promotes mould growth and significantly increases energy consumption on chilled water and refrigeration systems.The solution is correctly specified and installed pipe insulation with an effective vapour barrier.Which Pipes Are at Risk?Any pipework operating... Read more...
Condensation on Refrigerant Pipework
Why Refrigerant Lines Are High RiskRefrigerant suction lines operate at some of the lowest temperatures found in building services pipework — typically between -10°C and +10°C depending on the refrigerant and system operating conditions. In a typical UK plant room or roof-mounted installation, the pipe surface temperature can be 20–30°C below the ambient air temperature.At these temperatures, condensation is not a risk — it is a certainty unless the insulation system is correctly specified and installed. The dew point of typical UK ambient air at 20°C and 60% relative humidity... Read more...
Air Source Heat Pump Pipe Insulation Guide
Introduction Air source heat pumps (ASHPs) rely on correctly insulated pipework to deliver their designed efficiency, prevent condensation, protect outdoor services, and comply with UK installation requirements. Because a heat pump operates across several different temperature ranges, no single insulation material or thickness is suitable for every pipe on the system. For a complete overview of heat pump pipe insulation, visit our Heat Pump Pipe Insulation Hub. This guide explains how to specify insulation for the heating flow and return, domestic hot water pipework, refrigerant lines, outdoor connections, valves, fittings,... Read more...
Outdoor Pipe Insulation for Heat Pumps
Introduction The outdoor pipe run between the heat pump unit and the building is one of the most critical and most frequently misspecified sections of a heat pump installation. Exposed to UV radiation, rain, frost, and temperature cycling, standard pipe insulation materials will degrade rapidly — often within 12–24 months — if the wrong product is specified. For a complete overview of heat pump pipe insulation, visit our Heat Pump Pipe Insulation Hub. This guide covers the correct materials, installation methods, and compliance requirements for outdoor heat pump pipe insulation... Read more...
Heat Pump Pipe Insulation — BS 5422 & MCS Requirements
Introduction Every heat pump installation in the UK that claims the Boiler Upgrade Scheme (BUS) grant must be MCS-certified. MCS certification requires all pipework to be insulated in accordance with BS 5422 and the heat pump manufacturer's installation manual — and building control sign-off under Part L of the Building Regulations requires the same. For a complete overview of heat pump pipe insulation, visit our Heat Pump Pipe Insulation Hub. This guide explains exactly what BS 5422 and MCS require for heat pump pipe insulation, how to demonstrate compliance, and... Read more...
Heat Pump Refrigerant Line Insulation
Introduction The refrigerant lines on an air source heat pump are the most technically demanding pipework to insulate on any domestic or light commercial installation. The suction line operates at temperatures well below ambient — creating significant condensation risk — while the discharge line operates at high temperatures that can exceed the rating of standard insulation materials. For a complete overview of heat pump pipe insulation, visit our Heat Pump Pipe Insulation Hub. This guide covers the correct insulation specification for heat pump refrigerant lines — suction line, discharge line,... Read more...
Ground Source Heat Pump Pipe Insulation Guide
Introduction Ground source heat pumps (GSHPs) extract heat from the ground via a buried loop of pipework filled with a water-glycol mixture (brine). The brine circuit operates at temperatures close to or below freezing — creating condensation and frost risks that require careful insulation specification on the above-ground sections of the system. For a complete overview of heat pump pipe insulation, visit our Heat Pump Pipe Insulation Hub. This guide covers the correct insulation specification for every pipe on a ground source heat pump installation — brine flow and return,... Read more...
