Can Mould Grow on Fibreglass Insulation?

It’s not likely that you spend a lot of time in your roof space, crawl-space under your floors or in your walls looking at your insulation, but it can be worth periodically checking in as there’s a hidden danger most of us don’t even consider nestling and growing away in the structure of our homes.

That danger is mould. But can mould grow on fibreglass insulation? Worryingly, it can.

Mould can cause dampness and odour throughout your house as well as being a danger to the structure of your home.

It also releases allergens and pollutants into the air, lowering air quality and even, in extreme cases, negatively affecting your health and wellbeing.

You need to consider here if fibreglass insulation is the right thing for you to use; as it’s not cheap, and will likely need replacing again in the not-so distant future

How Does Fibreglass Get Mouldy?

Most home insulation, and the type you’ve probably seen before, is made up of fibreglass pads. It’s a thick, sharp, scratchy cotton-wool type material that’s dense and heavy. In roofs, it’s normally lined up on the floor of a loft in large square panels.

The nature of the material and the panels mean that there’s small gaps between them, and that the insulation absorbs a degree of dust and moisture from the air and any surfaces around it. This moisture then settles into stagnant damp within the material.

The heat and changing temperatures of the areas that insulation is set in means that this moisture often grows into mould – rendering your fibreglass insulation smelly, less effective, and wet!

Of course, with your fibreglass insulation being in a compact space, once it is wet it can take a long time for it dry out again, during which time it loses its insulating properties and is a festering ground for mould and other nasties.

What should I do if my fibreglass insulation is mouldy?

Mouldy patches of fibreglass insulation indicate air escaping the area – exactly the opposite of what you want to happen with your insulation! Fibreglass insulation that’s gone mouldy will need replacing, and often the area around or behind it will need re-insulating with another layer to prevent any further escaped air.

Spray foam also does a good job for its primary purpose – keeping heat in and chills out! The spray foam is the market leader in heating, offering savings of up to 35% of energy bills, making it considerably more effective than other options

What Are The Alternatives?

Insulation doesn’t have to come in panel form, nor does it have to be susceptible to mould and rot.

Spray foam insulation is the latest technological development on the market. Unlike panels of set material, it expands to fill the space around it (up to 100x the size of its original form, in fact!), so all areas are completely sealed against escaping air.

Spray foam insulation forms an entirely protective barrier against moisture and is unaffected by humidity due to its chemical make-up. This means that it can’t rot and mould can’t grow on it, no matter how long the foam has been in place.

Are There Any Other Benefits To Spray Foam?

The are lots of benefits.

Spray foam insulation is so thick that it can actually have structural benefits for your home, depending on where its installed. There’s no wobbly standalone pieces of material here!

The nature of the foam means that it completely blocks out dust and other allergens that can otherwise enter the air of your home through the floor, wall or roof cavities. Lots of spray foam customers report near-immediate improvements in their general health, with particular benefits for those with asthma or allergies. Air quality dramatically improves helping those prone to breathing issues.

In roofs, there’s also opportunity for to reclaim some valuable living space. Traditional fibreglass insulation lays across loft floors or beams, and is normally around 10 inches thick.

Spray foam instead is installed directly into the lining of the roof cavity, giving you back just not a 10-inch layer of your floor space – but the whole loft!

You may also learn that, contrary to a common belief, spray foam insulation is cheaper than fibre glass.
