Benefits of using nitrile rubber pipe insulation

We have looked into the benefits of pipe insulation in our previous blog. So, we know that pipe insulation helps the plumbing in your home function more efficiently. In addition to saving energy costs, pipe lagging helps reduce your carbon footprint. Pipe Insulation protects pipes from condensation, sweating and other issues.

By lagging pipework, pipes remain protected from extreme temperatures, dirt and corrosion. Therefore, it is essential to insulate pipes and ducts in your homes, commercial settings and industrial settings.

Pipes in the cold spaces of your home need to be insulated as well. If you have a cold roof, then the mineral wool loft insulation rolls laid down between and over the joists effectively stop the heat at the ceiling level. This means that the pipes and tanks in the loft are often exposed to freezing temperatures. 

So, leaving them un-insulated can quickly become a reason for many problems. Uninsulated pipes can freeze or burst, which in turn could damage your furniture and belongings. It could also make the mineral wool loft insulation  wet, causing moulds and other problems. 

There are many pipe lagging options available. Besides, when you buy pipe insulation online, you get easy access to many sizes and specifications of the pipe lagging, something that may not be available at your local vendor. 

Some of the pipe lagging products that buy insulation online has in store for you are:

This foam pipe insulation gives exceptional thermal insulation to all types of pipework. It is a cost-efficient, easy-to-install and energy-saving solution. It is used to insulate sewage pipes, hot and cold-water pipes, among others, in both residential and commercial facilities.

The focus of this blog, however, is nitrile rubber pipe insulation:

What is nitrile rubber pipe insulation made of?

The nitrile rubber pipe insulation is made of nitrile rubber or Buna R, a most commonly used elastomer. Nitrile rubber consists of unsaturated copolymers of acrylonitrile and butadiene monomers. The chemical and physical properties of nitrile rubber vary based on the polymer makeup.

What sets nitrile rubber pipe insulation apart?

The nitrile rubber pipe insulation has many distinguishing features, like high abrasion resistance and high tensile strength. It is much stronger and resilient to oils and acids. It is also highly flexible in nature.

The class 'O' insulation:

The class 'O' rating of the nitrile rubber means they protect the pipe surface from spreading flames while also reducing the amount of heat emitted during a fire. The nitrile rubber protects pipes against cold and hot temperatures by reflecting radiant heat away from the surface of the pipes.

The closed-cell nature:

Nitrile rubber pipe lagging is closed-cell insulation. The nitrile rubber is exposed to a blowing agent like nitrogen under extremely high pressure. The process incorporates many tiny molecules in the fabric of the pipe insulating material. Each of these tiny molecules is filled with the blowing agent. The blowing agent acts as a protective thermal barrier when compared to air. The closed-cell nature also makes the insulation much denser. The closed-cell nature of the pipe lagging also restricts the transfer of heat, thus reducing energy loss.


Nitrile rubber pipe insulation is naturally moisture resistant. The nitrile rubber pipe lagging is resilient to water ingress and moisture build-up. It does not wick moisture, protects metal pipes and keeps them dry while also keeping corrosion at bay. 

Anti- microbial:

Closed-cell nitrile foam pipe insulation has antimicrobial properties that prevent mould and germs from growing. Also, since the moisture build-up is almost negligible, the formation of moulds, bacteria and other organisms can be kept in check.

Highly flexible:

Nitrile rubber insulation is a very adaptable and versatile material. The rubber foam pipe insulation is highly flexible. It can be easily moulded into shape, therefore is ideal to insulate pipes on uneven or odd shapes of the pipes and ducts.

The closed-cell elastomeric insulation is impervious to water, oil, and most acids. It's perfect for insulating vessels, curved or irregular shapes, because of its elasticity.

Corrosion resistance:

Since nitrile rubber foam pipe insulation does not allow moisture in and helps keep corrosion is kept to a minimum. 


Unlike wool insulation, the nitrile rubber pipe insulation is free of dust and tiny wool fibres. They do not contain any CFCs and have zero Ozone Depleting Potential, making them an environmentally friendly product.

Uses of nitrile rubber pipe insulation:

Nitrile rubber insulation is flexible, closed cell, and elastomeric. Some of its applications include:

  • Duct Insulation
  • To insulate water tanks.
  • To protect cold water supply units and chilled water lines from freezing over.
  • For reducing energy loss in hot and heating systems. 
  • HVAC applications like air conditioning ductwork and refrigeration pipework.  

Key features of nitrile rubber pipe insulation: 

  • Condensation Control: The elastomeric, nitrile rubber foam pipe insulation prevents condensation on refrigeration copper piping, heating and ventilation pipework, and air-conditioning pipework. 
  • Versatile Applications: There isn’t much nitrile rubber foam pipe lagging cannot do for you. When insulated properly and when working within its claimed temperature range, the rubber foam lagging saves energy loss in both hot and cold plumbing lines, as well as a ducting insulation blanket.
  • The rubber foam pipe lagging is resistant to water vapour. 
  • They offer excellent adhesion to adhesives and coatings.
  • The insulation is easy to cut, carry and install. Installing nitrile rubber lagging on pipes is an easy DIY task.
  • It significantly reduces energy costs.
  • It operates efficiently in a wide temperature range -50 °C to +110 °C.
  • The nitrile rubber pipe insulation increases the life of your plumbing in industrial, commercial and residential applications. 
  • They are cost-effective, easy to install and highly flexible.
  • Nitrile rubber pipe lagging slows down pipe-freezing by providing effective insulation.
