How Long Does Insulation Last?

How Long Does Insulation Last
 

It’s a common misconception that once your attic has been lined with fibreglass insulation panels, that they can be trusted to do their job.

Under ‘optimum conditions’ traditional insulation panels should last up to 100 years. In reality, not quite; or even, not close. So how long does insulation last for, and why doesn’t it last longer?

Why Traditional Materials Fail

Fibreglass insulation panels are the traditional, standard insulation for most houses. They’re made up of a kind of glass wool in large square panels that looks like stiff cotton wool but is scratchy and rough to the touch.

They’re commonly laid across the floor of attics and lofts, in thicknesses of about 10 inches, and consequently, take up a great deal of space.

It’s no secret that most of us find our loft spaces a bit damp and dusty, and when you factor fibreglass’s flawed functionality into the equation, it’s easy to see why.

This is not the ‘optimum conditions’ required for insulation with a 100-year lifespan.

Rather, it can start to deteriorate as soon as it comes into contact with the floor and the air. Your 100-year lifespan can very quickly become less than 10.

Spray Foam: A Thoroughly Modern Method

Insulation panels of this type are prone to damp, moisture and mould. Water damage – whether it be a full-on leak from your roof, or just residual moisture in the air – can severely reduce the effectiveness of your insulation, and when pinned up against ceilings or walls, even cause it to rot and fall down.

Short of constantly nipping upstairs to check on the state of it, what can you do?

Invest in something new. The latest in insulation technology comes in a completely different material form; a spray foam from a can.

Icynene is currently the market leader in innovative insulation technology, transforming the efficacy of homes almost instantly.

As it leaves the can, this multi-purpose foam expands to up to one hundred times its original size, and then dries.

This creates an effective barrier to all water (regardless of how much of it there is in the air, or surrounding area), and seals up even the most unusual of spaces, nooks and crannies.

Space, shape and volume don’t matter, as the nature of the foam means it creates an effective seal around anything.

Spray foam insulation must be installed by an expert Home Logic technician. It’s sprayed (or injected) directly into the roof cavity, rather than lined across your floor – so you can reclaim your loft space as an ambient living area and have a new usable room in the house.
