What is Pipe Insulation
Pipe insulation is a protective layer that is wrapped around pipes to maintain their temperature. This layer also helps to prevent any damage to the pipes due to external elements. Pipe insulation is commonly used in homes for water pipes, gas pipes and pipes of HVAC systems.
Benefits of Pipe Insulation
Pipe insulation is made of materials like foam, rubber or fiberglass, that help to minimize heat loss. As a result, a constant temperature is maintained within the pipes. Due to this feature, lesser energy is utilized to heat or cool the fluid running in the pipes and you save on your utility bills.
Additionally, pipe insulation prevents the formation of water droplets outside the pipes. Otherwise, these droplets can lead to rusting or mold growth, which can damage the pipes over time.
Hot water pipes should always be insulated. It helps to retain heat for a longer period of time. Insulation also helps minimize the noise coming from pipes.
What is Foam Pipe Insulation
Polyurethane foam is one of the most popular products used for pipe insulation. PVC foam pipe insulation is a versatile product that is lightweight, easy to install and available in flexible tubing or rigid sheets.
Some common foam pipe insulation types include:
1. Polyethylene:
It is
versatile, abrasion-resistant and water-resistant. It is mainly used for both
cold and hot water pipes.
2. Polyurethane:
Thermal
resistance of insulated pipes is measured by the R-value. Higher R-value means
better insulation. Polyurethane has a high R-value that makes it a good choice
for both hot and cold water.
3. Elastomeric:
It is a
highly flexible rubber foam, which makes it suitable for pipes that move and
produce vibrations.
4. Polyolefin:
It is a
closed-cell foam that has a water-repellent property. It is mainly used for
cold applications.
When choosing
foam pipe insulation, ensure adequate temperature rating and wall thickness for
the pipe use.
What Are Some Considerations for Purchasing Pipe Insulation
Insulating materials like foam insulation, fiberglass insulation, calcium silicate and many other options are available. Keep in mind these key factors when selecting insulation pipes:
Temperature Range:
The
insulation material should also be compatible with the pipe temperature. Some
provide additional heat or cold shielding.
Location:
Will the
insulation be subjected to weather exposure, moisture or physical impact?
Select durable materials that match the location’s settings.
Fire Protection:
Fiberglass
and calcium silicate pipes offer fire protection, while foams need extra
protection in the form of fireproofing barriers. If the area is prone to fires,
select these materials.
Ease of Installation:
Flexible foam tubes are easier to install on pipes than on any other surface. Rigid boards require gluing/sealing. Before settling, make sure to factor in how flexible your pipes need to be.
Use different
insulation materials where necessary. For instance, cold water pipes in damp
areas should be installed with water-resistant insulation and an exterior fire
barrier wrap.
How to Install Pipe Insulation
Pipe
insulation has a simple set of steps to follow for installation. Follow these
guidelines for a proper pipe insulation installation:
Materials
fitted adequately on the pipes enhance building efficiency, avoid moisture
problems and support ideal pipe temperatures. Manufacturers of insulation
products provide guidelines for their respective uses. For more details, refer
to the pipe manufacturer’s manual.
