Insulation Health Hazards: All You Need To Know

Insulation Health Hazards

The air quality within your property should encourage good health; after all, if you can breathe easily anywhere, it should be in your own home! However, there are a number of factors that can impact on internal air quality, and, in turn, the health of the residents inside.

It’s not often considered but this could be caused by the insulation in your roof, walls or ceiling. Don’t let insulation health hazards compromise your happy, healthy home: fight back! Here’s how…

Insulation Health Hazards #1: Inhaling Fibreglass

The most traditional and common form of insulation is made up of fibreglass strands, and comes in fabric type rolls or panels. The material looks like candyfloss, but is scratchy and hazardous to touch, as it will cut and graze skin.

As the insulation ages, the tiny particles of glass may come away from the roll and become airborne. As with any sharp glass particles, these can cause irritation to the skin and eyes and if inhaled, and can be extremely dangerous.


Spray foam insulation is an industrial spray that doesn’t deteriorate over time, and doesn’t sag or lose its shape. With the consistency of sponge cake, there’s nothing in it to break away and float into the air around it.

Insulation Health Hazards #2: Mould growing on insulation

Insulation is often placed in cold, dark areas of a property, and so can easily become the perfect breeding ground for mould. Mould, when allowed to prosper, releases spores and allergens into the air that can be irritating and harmful when inhaled.

In severe cases of prolonged exposure to black mould, respiratory conditions can develop in individuals.


An insulation product such as spray foam insulation naturally won’t allow mould to grow on it, due to its sophisticated chemical make up. Fully sealing the property off from the outside world then ensures there are no gaps present through which mould can enter.

Insulation Health Hazards #3: Damp seeping through insulation

Traditional insulation products do not entirely absorb moisture, but will to a degree. When placed against a damp exterior wall or wet surface, they will absorb an amount of water, and bridge this through to the interior of the property.

When this happens, damp seeps into interior surfaces, and is extremely difficult (and costly!) to get rid of. Being around damp aggravates respiratory conditions such as asthma, and can exacerbate existing symptoms.


Spray foam insulation does not absorb any moisture, and instead of thermally bridging moisture into the home, thermally blocks it instead. This creates a water-tight seal around the property to combat damp, and keep the interior brilliantly bone-dry, regardless of the weather outside.

Insulation Health Hazards #4: Recycled newspaper ink off-gassing

Cellulose insulation is made up of recycled newspaper that is chemically treated to make it fire-retardant. As cellulose ages and absorbs moisture, the chemical mixes with the ink, and ‘off-gasses’ harmful toxins from the ink.

An individual inhaling these off-gassed chemicals can experience respiratory difficulties as a result of chemical residue settling into the airways and lungs.


Spray foam insulation is made up of 50% a chemical mix and 50% water. Despite containing chemicals and formaldehyde, there is no risk of off-gassing, and third-party laboratory testing has shown that even immediately after application (whilst the foam is still wet), only ‘trace’ amounts of any chemical can be found in the air – and well below the recommended standards.

There are no toxic ingredients within the chemical mixture, and, therefore, none to be released into the air.

Spray foam insulation can be installed by our talented team of technicians, who are recommended Which? Trusted Traders, and certified by the BBA (British Board of Agrement). Our expert technicians can ensure a safe installation, and the perfect seal for your home to encourage a purer air quality within.
