Types of Pipe Insulation: 6 Essential Solutions for Energy Efficiency

Fiberglass Pipe Insulation

Fiberglass is one of the most common types of pipe insulation. It is made from fine strands of glass that are spun into a wool-like material and bonded with a resin.

Fiberglass pipe insulation can be found in various forms, such as rigid boards, flexible blankets, preformed sections, or loose fill. Fiberglass pipe insulation is typically used for hot-water pipes, steam pipes, HVAC ducts, and refrigeration lines.

Some of the advantages of fibreglass pipe insulation are:

• It has a low thermal conductivity, which means it can effectively reduce heat loss or gain from pipes.
• It is non-combustible and fire-resistant, which means it can enhance the safety of your piping system.
• It is resistant to mould and mildew growth, which means it can prevent moisture problems and health hazards.
• It is easy to cut and fit around pipes and fittings, which means it can be installed quickly and efficiently.

Some of the disadvantages of fibreglass pipe insulation are:

• It can irritate the skin, eyes, and respiratory system when handled or cut, which means it requires proper protective equipment and ventilation during installation.
• It can absorb water and lose its insulating properties when exposed to moisture or humidity, which means it requires a vapour barrier or jacketing to prevent condensation.
• It can deteriorate over time due to mechanical damage or UV exposure, which means it requires regular inspection and replacement.
