The Benefits of Spray Foam Insulation for Your Loft

When it comes to home insulation, spray foam is becoming an increasingly popular option for many homeowners. Spray foam insulation is a type of insulation that can expand up to 100 times its original size to fill every corner and crevice, creating a tight seal that can prevent heat and air from escaping. In this article, we'll explore the benefits of spray foam insulation, particularly in the loft, and why it is a superior choice over traditional insulation methods.

Insulating your loft is important for several reasons. Not only can it help to reduce your energy bills by preventing heat loss, but it can also make your home more comfortable, particularly during the colder months. Traditional insulation methods, such as fiberglass, can often leave gaps and voids where air can escape, reducing their effectiveness. Spray foam insulation, on the other hand, can fill every corner and crevice, creating an airtight seal that can deliver up to 50% greater energy savings compared to other insulation products.

So why should you choose spray foam insulation for your loft? In addition to its superior insulating properties, spray foam insulation can also offer a range of other benefits. In the following sections, we'll take a closer look at the types of spray foam insulation available, how it works, and the various benefits it can provide.

What are the Different Types of Spray Foam Insulation?

Spray foam insulation comes in two main types: open cell and closed cell.
Understanding the differences between these two types can help you choose the right one for your home.

Open Cell Spray Foam

Open cell spray foam is a soft, spongy material that is great for insulation in areas with timber frames. It is made up of cells that are not completely closed, allowing air to fill the spaces in the material. This type of spray foam insulation is highly effective at reducing noise pollution and improving indoor air quality as well as improving the efficiency in your home by retaining heat much better than other traditional methods of insulation.

Open cell spray foam is perfect for insulating hard-to-reach areas because it expands up to 100 times its original size, acting as an air tight application. It is also highly flexible and can expand and contract as the temperature changes. This makes it ideal for use in areas where timber frames need to breathe naturally, while still maintaining high levels of insulation to prevent drafts and heat loss.

Open cell spray foam is used widely in homes as it's fully breathable and meets building regulations.

Closed Cell Spray Foam

Closed cell spray foam is a more rigid material that is highly effective at reducing heat loss and improving energy efficiency. It is made up of cells that are completely closed, which prevents air and water from entering the material. This type of spray foam insulation is highly recommended for use in areas that are exposed to high levels of moisture, such as bathrooms and kitchens.

Closed cell spray foam is an excellent barrier against moisture and can help prevent the growth of mould and mildew. Its high density makes it a strong material that can provide additional structural support to your home. It is ideal for use in areas that are prone to wind damage or are exposed to harsh weather conditions.

Closed cell spray foam is not to be used in your home and is instead used on commercial buildings and metallic roofs to stabilise moisture and condensation.


Open cell spray foam is great for insulation in areas with timber frames, while closed cell spray foam is ideal for areas that are exposed to high levels of moisture or need additional structural support. Understanding the differences between these two types of spray foam insulation can help you make an informed decision about which one to choose for your home.

How Spray Foam Insulation Works

Spray foam insulation is a type of insulation that is applied as a liquid and then expands to fill all cavities and voids in the walls and ceilings of your property. This makes it an incredibly effective method of insulation that can significantly reduce energy bills and keep your home comfortable year-round.

When the liquid spray foam is applied, it expands to fill all spaces, creating a seamless, airtight seal that prevents drafts and air leakage. This creates an envelope of insulation around your property that helps to maintain a comfortable indoor temperature and prevents heat loss.

The airtight seal created by spray foam insulation is what sets it apart from traditional insulation methods. By preventing drafts and air leakage, spray foam insulation can significantly reduce energy bills by up to 50%.

Spray foam insulation is also effective at soundproofing your home by reducing noise pollution from outside. Its airtight seal can also help to improve the air quality in your home by reducing the amount of outside air that enters the property.

Spray foam insulation is an effective and efficient way to insulate a property. By creating an airtight seal, it helps to reduce energy bills and improve indoor air quality while preventing pests, moisture, and mould growth. Its ability to expand to fill all cavities and voids makes it a superior choice compared to traditional insulation methods. By understanding how spray foam insulation works, you can make an informed decision about whether it is the right option for your property.

Benefits of Spray Foam Loft Insulation

Spray foam loft insulation is one of the most effective ways to insulate a property. It offers a range of benefits that traditional insulation methods simply cannot match.
Here are some of the key benefits of using spray foam insulation for your loft:

Preventing heat loss:

One of the most significant benefits of spray foam insulation is its ability to prevent heat loss. By filling all the cavities and voids, spray foam creates a continuous air barrier that reduces heat transfer. This means that your home will be warmer and more comfortable, even in the winter months.

Reducing energy bills by up to 50%:

Because spray foam insulation creates an airtight seal, it helps to reduce the amount of energy needed to heat your home. This can lead to significant savings on your energy bills, with some homeowners reporting reductions of up to 50%.

Soundproofing and reducing noise pollution:

Spray foam insulation is an excellent sound insulator. It can help to reduce noise pollution from outside, making your home a more peaceful and quiet place to live.

Improving air quality and reducing allergens:

Spray foam insulation can help to improve the air quality in your home by reducing the amount of outside air that enters the property. This can help to reduce allergens such as pollen, dust, and other particles that can aggravate allergies and respiratory conditions.

Preventing pests and infestations:

Spray foam insulation creates an airtight seal that can help to prevent pests and infestations. It is an effective barrier against rodents, insects, and other pests that can enter your home through gaps and cracks.

Preventing moisture and mould growth:

Moisture is a common problem in many properties, and it can lead to the growth of mould and mildew. Spray foam insulation can help to prevent moisture from entering your home by creating an airtight seal. This can help to reduce the risk of mould and mildew growth, which can be a serious health hazard.

Strengthening the structure of the building:

Spray foam insulation is a dense material that can help to strengthen the structure of your property. It can help to support the roof, walls, and floors, making them more resistant to damage from wind and other weather conditions.

Spray foam loft insulation offers a range of benefits that can help to make your home more comfortable, energy-efficient, and healthy.

It is an investment that can provide long-term benefits for you and your family.
