How Polyester Insulation is Made

Polyester home insulation is a synthetic or man-made product based on petrochemicals. Some polyester products contain recycled plastic fibres, for example those from recycled plastic bottles. Others may be blended with products like wool. It pays to ask what the polyester product you are interested in is composed of.

Typically, polyester insulation comes in the form of blankets or rolls which are available in widths suited to standard spacings of wall studs, ceiling or floor joists. They sometimes come in segments which are often referred to as Batts or biscuits.

These forms of insulation may be installed in open walls during construction or home renovation; or installed in the ceilings of existing homes provided there is sufficient crawl space. Loose fill materials are available as well and they can be blown into cavities.

Polyester Home Insulation and Safety

This type of material should not emit any pollutants or airborne pollutants. Many polyester home insulation products are non-allergic, non-irritant and non-toxic. However, it is best to check with the manufacturer whether any chemical binders have been used to make it. Some binders may contain and emit pollutants.

In general, this material does not burn easily. To be sure of a polyester product’s fire-retardant qualities, check individual product information. Polyester home insulation materials are particularly strong and durable and do not degrade with time. Many products come with performance guarantees.

They are resistant to heat, cold and moisture and are not prone to mould or mildew. Polyester home insulation can also be recycled and reused. This makes it cost-effective as well as environmentally friendly.

Further, they come with an R-value for thermal performance. This rating measures how well insulation can resist heat flow or contain heat. A high R-value indicates the insulation is highly effective in slowing down the transfer of heat, thereby retaining the warmth within the home and reducing the amount of energy used for heating.

It is up to you to decide whether polyester is the best home insulation material for you. If you’ve done your research but still aren’t certain, have your home assessed for energy efficiency and ask the assessor about the pros and cons of using polyester home insulation.
