What is Lagging?
Lagging is the process of insulating pipes, boilers, and other hot water or heating systems to reduce heat loss. By wrapping these components in insulating material, you prevent energy from escaping, which keeps your systems running efficiently. Lagging can be applied to hot water pipes, central heating systems, and even ductwork on site.
How Lagging Reduces Energy Costs
Prevents Heat Loss: When hot water pipes are unlagged, a lot of heat escapes into the surrounding environment. Lagging keeps the heat where it’s needed, meaning your boilers and heating systems don’t have to work as hard.
Reduces Fuel Consumption: Less energy lost means less fuel is needed to maintain temperature, lowering your gas or electricity bills.
Improves System Efficiency: Properly lagged pipes maintain water temperature more consistently, improving the efficiency of heating systems and reducing wear and tear.
Minimises Maintenance Costs: Systems that run efficiently experience fewer breakdowns, which can save money on costly repairs.
Types of Lagging
Foam Lagging: Lightweight and easy to install, ideal for small pipes.
Fibreglass Lagging: Provides excellent insulation for higher-temperature systems.
Rubber Lagging: Flexible and durable, perfect for areas exposed to movement or vibration.
Tips for Effective Lagging on Site
Ensure all accessible pipes are lagged, including bends and joints.
Measure pipes carefully to avoid gaps in insulation.
Regularly inspect lagging for damage or wear.
Combine lagging with energy-efficient boilers or pumps for maximum savings.
Why Lagging is a Smart Investment
Investing in lagging may seem like a small step, but it can have a significant impact on reducing energy costs on site. Not only does it save money, but it also contributes to sustainability goals by reducing unnecessary energy consumption.
