What is the Difference between Polyetheramine and Polyester in Foam Insulation

There has been a lot of talk in the polyurea insulation market regarding polyetheramine (PE), compared to polyester (PU). Some companies have said that polyurea is a much better product than polyester, because of its extreme thermal qualities. However, other companies have made statements stating that polyureas are not as good as polyester foam insulation. The truth lies somewhere in between, although most people believe that polyureas are better than their foam counterparts. So, what is the real difference when it comes to polyurea and polyester?

Polyester is an extremely dense foamsaver, which makes it one of the most expensive types of insulation available on the market today. PE is a highly advanced type of foam, which offers many benefits to the homeowner in comparison to other types of foam products. For instance, polyureas do not sag or wrinkle, so they will last a lifetime. They also do not retain odors and are resistant to fire and carbon buildup.

As you can see, polyurea does have many advantages over polyester insulation. However, these same advantages come with a price tag. For one thing, they are more expensive than polyester, which leads some people to believe that they are no better than the less expensive foam insulation choices. While polyurea does offer some excellent benefits, this does not mean that it is worth paying full price for your home. In fact, many foam insulation products cost less than polyureas, and if you shop around, you will likely find that it is possible to find polyurea at a lower cost, as well as a number of other excellent foam insulation products.

If you are shopping for foam insulation, you should know that polyester is far superior to polyurea in both quality and price. However, even with polyurea, there are excellent options. For instance, polyurea blocks heat very well, but it does not insulate well. This is why it is typically only used in high-efficiency refrigerators and air conditioners, and not in heating systems.

Since polyureas insulates better than polyester, and is almost always cheaper than polyester, it is often used in place of polyester in foam insulation. Although polyureas are generally superior, they are still nowhere near as efficient as polyester. For this reason, if you need extra warmth inside your home, polyureas should be avoided, as they will not do anything to resolve the problem. However, if you are trying to save money, polyureas are an excellent choice.

As you can see, it is easy to understand how polyurea compares to polyester in foam insulation. Both provide great performance, although polyurea is just a step ahead because it is more cost effective and insulating. It is also an excellent choice if you want extra warmth inside your home, especially if you are looking to keep the price of your heating bills down. Just make sure that you double check the amount of insulation in the spray foam has, because too little polyurea spray will not do you any good.
