Will Accessibility Affect The Success Of My Spray Foam Installation?

We all know that insulation is one of the best ways to make our homes warmer and more energy efficient. But what if your loft is difficult to access and there is just no room for the all important layer of insulation that is recommended?

Should you just do without? Or will another method of insulation work better for you? Spray foam insulation is the perfect answer to difficult to access loft spaces and even the most inaccessible spaces will benefit from spray foam. Here’s why..

Why Should I Insulate My Loft Space?

Heat rises. This one fact is the reason why it can be so hard to keep our homes warm in the winter months. All that heat that you are generating from your central heating, electric heating, your open fires or your wood burners is heading for one place – the top of your house.

In most cases, your home will have a loft space that is separated by a standard ceiling. If this ceiling is not insulated, the hot air will enter the loft space and then exit your home through the roof.

You can insulate the floor of your loft to prevent the easy passage of warm air into your loft. The Energy Saving Trust tells us that 270mm of mineral wool insulation will provide enough energy efficiency to save a few hundred pounds every year – depending on the size of your home.

The other option is to use spray foam to insulate the underside of your roof – turning the loft space into a warm area. If you choose to use spray foam insulation the depth of your insulation needs to only be 100mm – saving you plenty of space.

Your choice of insulation may be influenced by the shape and design of the loft space and could result in standard forms of insulation being a poor choice.

Seeking structural support for your roof? Spray foam can help in this respect as well, making it ideal for roof restoration and sealling up long-term leaks

Why Some Lofts Are Inaccessible

For many homes, the loft space is a simple design that allows full access to all of the roof and the full area of the floor.

This A-frame type design gives a peak in the middle of the roof that then slopes away to the edges at each side. The area right at the edge of the roof can be tight – but it is accessible.

Other roof designs can cause all kinds of insulation issues. Dormers for example will be built with a number of framing options that can provide smaller spaces and spaces that are often hidden once the work has been completed.

Other designs leave the loft room with small crawl spaces that are behind plasterboard, areas that are impossible for a human to enter as they are simply too small and areas that are boarded up and hidden, but where hot air can escape to the outside.

Any home with an unusually designed roof structure will benefit from spray foam insulation as it offers a more flexible approach to the application.

Spray Foam Loft Insulation: An Overview

Most people will know about the cans of spray foam we can buy at the DIY store. These are designed to fill small spaces – maybe around window fittings or where the floor meets the walls. Spray foam insulation is simply a larger version of this technology.

Two chemicals are forced together under pressure to provide a liquid foam that expands to many times its original size. When applied by an expert it can be used to insulate walls, roofs and floors all over your home.

Spray foam insulation is known to be waterproof and very long lasting. These are just two of the ways that it outshines other insulation methods.

It is also more energy efficient with a better thermal value and it can even offer a structural element to your roof and walls giving your home protection from weather events. You can even make your roof last longer by adding a layer of spray foam insulation to the tiles.

Best of all, spray foam insulation is incredibly flexible and can be used in almost any tight spot.

A professional contractor understands the best ways to apply the spray foam for the best effect-ensuring hard-to-reach areas are addressed

Insulating Loft Spaces With Spray Foam: The Process

It is almost always a good idea to have an expert add spray foam insulation to your home – the process involves the mix of two chemicals, and, therefore, protective gear is needed. Once the curing process is complete (within hours) the property can be reoccupied.

The professional will also understand the best ways to apply the spray foam to all parts of your home for the best effect – especially those tight and hard to access spots.

There are a number of techniques a professional will use to access all parts of your loft space, including the following:

● The standard way that spray foam is applied is by adding a layer of the foam between the wooden roof structure, and directly to the underside of the roof tiles. This is the simplest method, and can be carried out wherever these areas are exposed.
● Some of these roof areas may be enclosed by plasterboard. The boards can sometimes be easily removed and replaced once the insulation has been applied. If the plasterboard has been simply screwed into place, this is relatively fuss free.
● Because the spray foam insulation is applied using a hose, it is possible to apply it even in small crawl spaces – provided there is enough room for the contractor to enter.
● If the plasterboard cannot be removed, small holes can be drilled into the plasterboard and the spray foam nozzle fed through. This is perfect for small spaces that can be entirely filled with the foam. However, it can also be carefully used as a technique for coating the floor or walls of the space.

Spray foam is around 50% better at keeping the heat in your home than other forms of insulation-and will perform for the life of the building!

Insulating Inaccessible Areas: Why Spray Foam Strides Ahead

The aim of the contractor is to ensure your loft is as air tight as possible with all access points to the outside coated in the insulation. 

Spray foam insulation is already around 50% better at keeping the heat in your home than other forms of insulation, such as mineral wool. It can also be used in less accessible parts of your home, where standard insulation is not possible.

These two factors alone make spray foam insulation the perfect option for the best possible insulation job. Even if there are some gaps – the result will be a huge improvement.

The success of the insulation job on your home will also be down to the contractor. It is vital that you choose a professional who understands how spray foam works and the limitations of the product.

They need to be experienced in applying the product in hard to reach areas, and have the ability to understand the structure of your roof – so they can identify those areas that require special treatment.

Spray foam insulation on a home where the roof structure is unusual or a tight space may be slightly more expensive to install, but with the right contractor, and the time taken to gain as much access as possible, you can be assured that you will soon be saving money on your energy bills and enjoying a warm and comfortable home, all year round.
