There is a different price for each thickness that you can choose from. The thicker you go the higher the isotherm price will be. Give us a call and let us give you a price on installing isotherm in your home or office.

If you find you are getting a cheap isotherm price in comparison to what we are quoting you, make sure you are getting the right thickness installed.

How Is it Made?


Isotherm is a polyester insulation, made from recycled PET bottles that form a plastic resin. Polyester is very pleasant to work with because it does not contain chemicals like cellulose fibre insulation or itchy fibres like Aerolite. Polyester insulation will not absorb any water or moisture, and will most definitely dry if exposed to small amounts of liquid. It is a strong polyester product and will not disintegrate or break easily and withstands handling while it is transported and while our installers are installing it in your roof.

Fire Classification


Isotherm has achieved a B/B1/2 fire classification rating and is safe to use in residential and commercial buildings. If a fire were to break out, isotherm would self-extinguish if the source of the heat is removed and the polyester does not contribute to the spread of flame. It is still considered a good idea to keep isotherm away from heat sources or open flames.

Reduces Heating And Cooling Costs


If you are looking for ways to reduce your power consumption. Then having isotherm insulation installed by our professional installers is a great way to start. You can use it as a geyser blanket and wrap your hot water pipe with it too. This will decrease energy consumption even more. Being a polyester insulation, isotherm is resistant to condensation. It is also resistant to things like bacteria and fungi that you could acquire from other insulations like cellulose fibre if it gets wet. It is also an allergy-free insulation and the most eco-friendly insulation South Africa has to offer.

What Is The Lifespan Of Isotherm?


As it is a polyester insulation, isotherm has an extremely long product life. It will under no circumstances degrade over time. Furthermore, it is also recyclable. Have isotherm professionally installed to help reduce the power you consume in your home and office. Maintain a comfortable living environment throughout the year.

Eco-Friendly Recycled Insulation


Lately, as the world is becoming more environmentally conscious and people looking to be more eco-friendly using recycled materials, products like isotherm recycled insulation has become extremely popular over traditional insulating materials.

Isotherm has done an amazing job of taking plastic bottles and converting them into polyester insulation in South Africa. This product is made solely from recycled materials and contains no chemicals and itchy fibres and is 100% eco-friendly!

How Does PET Become A Recycled Insulation?


Millions of plastic bottles (also known as PET) get sent to dump sites all around South Africa every year. These plastic bottles are a hazard to our environment. Isotherm has taken up the challenge of gathering as many of these bottles as they can. They find and process them into plastic pellets. These pellets are then woven into recycled polyester sheets. The sheets are then run through very expensive machinery to produce the best-recycled insulation we currently have in South Africa.
