SOLVED: Is Spray Foam Insulation Waterproof?

is spray foam insulation waterproof

One of the most common questions the team here at Home Logic get asked – is spray foam insulation waterproof? There’s not really a ‘one size fits all’ answer to this question.

However, we will try our best to fill you in on the most important information, so that you can decide whether spray foam insulation is right for your home!

So without further ado, is spray foam insulation waterproof? It’s time to find out…

Open Cell or Closed Cell: How Do They Compare?

When it comes to spray foam insulation, you’ll find two different types on offer: closed cell spray foam and open cell spray foam. The type you choose will depend on your property’s or project’s requirements.

For example, your budget, the age of your property and so on. However, the type of spray foam you use will also largely depend on the installation company you choose.

Some companies specialise in just one type of insulation. Home Logic Spray Foam is an example of open cell spray foam insulation – more on that in a moment!

What Does Closed Cell Mean?

Closed cell spray foam insulation is a popular choice for commercial projects, or any home with structural issues.

Although both kinds of spray foam insulation are generally made from polyurethane filled with bubbles of air or gas, closed cell spray foam insulation has a more rigid structure.

This means that it sets into a totally solid layer, which can be beneficial for older properties. It can support cavity walls, and reinforce tired old roofs.

How About The Open Celled Variety?

On the other hand, we have open cell spray foam insulation. This type of insulation is less rigid than closed cell spray foam, and it’s often used to soundproof homes in busy areas.

Because it also breathable, there is no risk of condensation build up, making this the ideal choice for loft insulation.

So is Spray Foam Insulation Waterproof or Not?

We bet you’re still wondering – is spray foam insulation waterproof or not? Patience! We’re getting to it! Generally speaking, it depends on the density of the foam. 

However, Home Logic Spray Foam will not absorb or wick water, due to its impressively airtight nature.

This is a huge bonus when it comes to ensuring your insulation lasts for years to come, and will provide a healthy return on your investment. Our spray foam insulation lasts for over 20 years, and you can expect to see a return on investment within just three years.

True, it may cost a little more to install than more traditional materials, like fibreglass (the average home costing around £1,000 for loft insulation with spray foam). But it soon pays for itself in terms of savings on energy bills.

Because it doesn’t absorb water, condensation and mould problems are eliminated. It’s breathable too, so ventilation in your loft space isn’t an issue.

Spray Foam: The Additional Benefits It Brings

Wondering whether spray foam insulation is waterproof isn’t the only consideration to take on board when thinking about insulating your loft. There are other benefits to spray foam insulation too.

The average home saves around £225 a year on energy bills – money that could be spent on your next family holiday, perhaps!

Not to mention you’ll enjoy a home that’s warmer and more comfortable during the Winter months. So no more huddling on the sofa with a blanket when the first flakes of snow start falling outside! Insulating your loft helps keep your home cool during the Summer months too, so you’ll be more comfortable all year round.

Home Logic Spray Foam is safe and non-toxic. As it’s blown into place, it can be used to insulate even the most cramped, awkwardly-shaped attic spaces, hardening on impact to provide a blanket of insulation for your home.

Make the Logical Choice

We firmly believe Home Logic Spray Foam insulation is the most effective product available on the market, and we hope you’ll agree.

Although open cell spray foam insulation may not be waterproof, it has many other benefits that make it an excellent choice when it comes to insulating your loft space.
