Having your home insulated is one of the most important things you can do in order to create a more comfortable indoor temperature in your home, without running up massive heating and cooling bills by the end of the month. People often underestimate the importance of having their homes and offices insulated with the right products that are SANS compliant for their climatic region.
One of the most popular products today is aerolite pink insulation, which has been used widely around the world for many years. In fact, for over 70 years, aerolite pink insulation has been the product of choice by most home-owners.
The new kid on the block would be the isotherm eco-friendly recycled polyester insulation that has also become a household name here in South Africa when the subject of having your home insulated comes up. These two products have many great advantages and we will explore some of them below.
Advantages of aerolite pink insulation
There are many advantages to using aerolite pink insulation in your home as roof insulation. It has amazing thermal properties, meaning it does a good job of restricting heat flow that would usually come into your home through your ceiling and make your house extremely uncomfortable during the summer season, and retaining the heat you create in the winter season so that you don’t have to keep the air conditioners and heating systems running right through the night just to keep your family warm. Another advantage of aerolite pink insulation is the fire rating. Being a fiberglass product it has a really high melting point.
Advantages of isotherm recycled polyester
Having said that, it doesn’t mean that isotherm doesn’t have a fire rating. We have noticed the companies who only install aerolite pink insulation often say that isotherm is combustible, which is not true. It just has a slightly higher fire rating. This is actually one of the advantages of isotherm recycled polyester. It might have a slightly lower fire rating, which again does not mean its combustible in any way, but it is 100% people friendly and does not contain fiberglass or loose strands that could possibly be inhaled. In fact you can stick your face directly in the isotherm product and inhale deeply and there would be no problem. If you are working inside your roof for any reason, it is not necessary to wear a dust mask when working with this product.
What is the fire rating of aerolite and isotherm?
- Aerolite pink insulation has an A class fire rating
- Isotherm polyester insulation has a B/B1/2 fire rating
As you can see above both products have a fire rating and both are deemed non-combustible during extensive testing. There are many factors to look at when choosing the best insulation for your home. Being the preferred installers of both the products for the manufacturers, we can give you an unbiased option on the two different products, and can help you select the product that best suits your needs.
Disadvantages of fiberglass
While aerolite comes with many good advantages, there are still some disadvantages to the product. Being a fiberglass product, it does help with the fire rating as mentioned above, but at the same time its not a product that should be inhaled. Always make sure you are wearing a dust mask when working in your roof if you have aerolite pink insulation installed.
What is the density of aerolite and isotherm?
This is another important factor to take a look at. The density of a product does play a role in the thermal and acoustic properties of the insulating material. For example, if you were trying to sound proof a room, a bar, or a night club, you would need a product with a much higher density in order to achieve the desired soundproofing results.
- Aerolite pink insulation has a 10kg density
- Isotherm polyester insulation has an 11.5kg density
Which thickness should you have installed?
Whether you decide to have the aerolite pink insulation or the isotherm recycled polyester installed, it is extremely important to have the right thickness installed in your home or office building. The new SANS building laws in South Africa have worked out which thickness you need to have installed in your home in order to be SANS compliant. These are not just some rules that have been put in place for no reason, if you decide to go with the thickness that is not recommended for you climatic region, it doesn’t matter which insulating product you decide to go with, you will not reach the required insulting effect you are hoping to achieve.
