How Much Does Spray Foam Insulation Cost?

Approaching a contractor, supplier or tradesman to ask ‘How much does spray foam insulation cost?’ is far too vague a question. Every project is different, there are different types of spray foam, no two buildings are exactly the same, and there may be existing insulation concerns to take care of too.

If you want to know the real cost, you are probably better off figuring out the payback time, rather than looking at installation costs. After several years, your insulation will have saved you enough money on your bills each month, quarter, or year that after a set amount of time, it starts actually making a profit.

If it costs X to install spray foam insulation in your home, but it increases the value of your home by X too, it’s absolutely worth the initial outlay.

We want to break down some of the key factors of pricing up a spray foam job, so that you can understand how hard it is for us to answer ‘How much does spray foam insulation cost?’.

Traditional Insulation vs Spray foam: Comparison

It’s true that spray foam costs more than old-fashioned insulation types, like fibreglass batts (which are not good for your health either).

A three-bed house might cost around £1,500 to have the loft insulated with spray foam, whereas traditional methods might cost just £600.

We are transparent about the extra cost of spray foam because we believe it offers many times the quality, insulation effectiveness and longevity.

Over time, spray foam has consistently proven itself as a better option. The foam itself comes in liquid form, and once applied it expands to around 100 times its original size, filling every nook and cranny, completely eliminating the chance that air will leak through (unlike fibreglass batts).

With spray foam, you won’t be shivering, you’ll be nice and smug, protecting you and your family from temperature-related health hazards.

Traditional insulation won’t really increase the value of your home all that much, as any prospective buyer knows that sooner or later, it’s going to have to be replaced. With spray foam, it’s a long-lasting solution that improves your EPC rating and your home’s sale value.

Types of Spray Foam Insulation

‘Wait, there’s more than one?’

‘Isn’t all spray foam the same?’

Interestingly, there are two different classifications of spray foam, which are ‘closed cell’ and ‘open cell’. Within these two different types, you might find loads of brands and suppliers, but all-in-all, their products will be either of these.

There are benefits to be had for both types, which is why they are used for different applications. Insulating the exterior of a building is a job better suited to closed cell spray foam, whereas open call is ideal for internal wall cavities and loft spaces, for example.

Spray Foam Insulation: The Capacity

Heat loss through the loft or attic space is the most common and prominent reason for those considering insulation.

The barrier here is that there are certain measurements to consider, and sometimes it’s not possible to lay beams on top of the insulation, effectively rendering the storage potential of the loft useless.

Fibreglass batts are less effective at insulating and reduce the opportunity to lay beams on top after, which is one reason why spray foam is a better option for loft insulation.

Despite this, there are cases where no beams can be laid on top of insulation at all, but to know this, an expert needs to take a look at the space.
