Does Fibreglass Loft Insulation Degrade Over Time?

does fibreglass loft insulation degrade

Humans are very sensitive to temperature changes, which means that you’re eventually bound to notice when your insulation isn’t doing its job properly.

After insulation has been installed, it’s easy to forget about the addition to your loft and just enjoy the warmer internal temperature of your home. However, when the temperature starts to drop, and your energy bills begin to increase, insulation will once more be at the forefront of your mind.

If you’re experiencing this reduction in temperature level first-hand, then the chances are you’ll start to wonder whether your insulation has degraded; in the case of fibreglass insulation, the question ‘does fibreglass lost insulation degrade over time?’ might arise. 

The simple answer is ‘yes’. Insulation is not designed to last forever, eventually it will begin to degrade and whilst you may not always be able to see the deterioration, you’ll certainly notice it. 

The Lifespan of Fibreglass Insulation

The lifespan of fibreglass insulation may come as quite a surprise. The general consensus is that fibreglass insulation can last roughly between 80 years and 100 years – which seems like a pretty amazing investment!

However, the product doesn’t normally last anywhere near the estimated century. One of the reasons behind this is the large number of ways that the natural degradation of the insulation material can be sped-up. 

If your home has gotten colder recently, then there are a number of things that could have gone wrong with your insulation…

While it’s difficult to avoid all potential causes of insulation damage and prolong the life of existing insulation, it’s possible to choose an insulation material that can better cope with the demands of being in your loft for many years

What Can Influence the Lifespan of Fibreglass Insulation?

The problem with fibreglass insulation is not that it degrades, but the sheer number of reasons that can cause the lifespan of the insulation material to reduce. Here are just five of the reasons existing fibreglass may no longer be effective:

1)    Insulation Settling or Moving – Over time loose insulation can settle and fall through gaps, causing the insulation to stop performing as well. 

2)    Water Damage – When water gets into some insulation materials, like fibreglass, it can cause the insulation to degrade faster and stop being as effective.

3)    Mould Growth – Water damage can often lead to harmful mould growth, which can influence the effectiveness of the insulation material. 

4)    Dirt and Grime – An insulation material that has started to become dirty or very dusty will not work as effectively as it once did. 

5)    Physical Damage – Any form of physical damage can stop an insulation material from properly insulating your roof, floors, walls or ceilings. 

Many of these influencers over the lifespan of fibreglass insulation are difficult to prevent and mean that your insulation degrades faster and stops being effective long before the expected lifespan of the product comes to an end.

The strength and effectiveness of spray foam insulation, along with the material’s excellent protection against mould and moisture problems (closed-cell spray foam both deflects water and has impact resistance), means that there’s a much lower chance of the insulation suffering from faster degradation-as well as some refreshing reductions on your energy bills!

Spray Foam Insulation: High-Quality Insulation for Energy-Efficient Homes

Spray foam insulation can be classed as a very modern insualtion material when compared to fibreglass, which has been around for more than 75 years. The insulation material is a highly effective choice that offers great energy-saving benefits. 

The unique properties of spray foam insulation also allow it to combat those everyday issues that cause an insulation material to degrade at a faster rate, making it a prime choice for loft insulation.

When you choose spray foam insulation, you get the benefit of an insulation material that:

  • Is hydrophobic
  • Can’t sustain mould growth
  • Is vapour permeable
  • Allows for seasonal shifting
  • Has an air barrier
