Polyester insulation is manufactured from recycled PET bottles. Plastic drink bottles are also recycled to reduce landfill. These bottles are heat bonded and there is no use of chemicals or any added fire retardants like boric acid (used in cellulose fibre insulation) that could be harmful to you.
The advantages of polyester insulation are that it’s NON-toxic and completely natural. In fact, it’s basically the same polyester used in duvets and pillows.

The geyser may burst, or maybe you need to change some of the wires, whatever the reason, it’s a comfort to know there is safe, non-itch insulation products installed without toxic fumes or fibres.

DOES POLYESTER INSULATION LOOSE THICKNESS OVERTIME
When choosing the right ceiling insulation for your home or office, you want to make sure it will maintain its thickness and R-value over time. Insulation that compresses overtime is not worth having because the thickness you pay for today will decrease over time. So will the R-value will decrease a few months down the line.
Polyester insulation will not compress over time. Its thickness is locked because it is a bonded blanket. Insulation that comes in roll form cannot be disturbed by strong winds. Insulation in loose-fill products could be blown around and reduce thickness in some parts of your roof while increasing it in other parts.
Polyester insulation has been tested and is safe to use in commercial and residential buildings. Achieving a B/B1/2 fire classification rating. It will not spread flame and will self-extinguish once the flame source has been removed. If the polyester insulation ends up in a fire it will not release any toxic fumes. This is the same with fiberglass insulation, and they both have not been treated with harmful chemicals.
