Stop Wasting Your Energy!

Energy bills are rising. You might believe there’s nothing to be done about it – but that’s not true. There is one good way to combat energy bills, and that’s to stop your energy from escaping the house through insufficient insulation. 

Did you know that 25% of heat lost from a home is lost through the roof? This is due to inadequate insulation. With spray foam insulation, you can cut down this amount to the low single digits. 

Live in Comfort

The truth is, your home doesn’t reach the levels of warmth that it should because it’s being lost. With spray foam insulation, it provides a great loft insulation as the heat will build to the desired point quicker, for cheaper, and then stay warmer for longer. 

Prevention of Pollutants

Ever been minding your own business only to have a heavy smell of smoke enter your home and pull you out of your focus? This is due to insufficient integrity in your home to block these irritants. Spray Foam Insulation can block all sorts of harmful substances, from toxic smoke to allergens, from entering your home.

Block the Outside Noise

The noise outside can be disturbing to your peace, especially in the busier cities in Scotland. With spray foam insulation, you can dampen the noise coming in, so you can get lost in your own world without disruption.

Longevity and Durability

To top it all off, Spray Foam Insulation will keep your Scotland home warmer for a long time. This is due to the hardening effect, which makes spray foam hard enough to stick around for many years through any type of temperature.

Spray Foam Insulation FAQs

Most frequent questions and answers about spray foam insulation in Scotland

Spray Foam Insulation is made from composite materials – polyurethane and isocyanate. Combined, they react to each other by mixing, expanding, and hardening. 

Both materials are sprayed from the same spray foam gun, expanding and forming hard foam over the area being sprayed. This makes for fantastic insulation, providing thermal resistance and protecting against any small gaps/cracks in the walls. This deters both air leaks and water. 

This will, in turn, help you maintain a consistent and comfortable temperature in your home by preventing its loss through the roof. It also prevents heat from entering your building, which is especially useful during the summer months.

Spray foam works by creating a barrier between the inside and outside of an environment. This barrier blocks all transfer of air, heat and water. When sprayed from a spray foam gun, this foam expands and hardens, filling gaps, cracks and crevices within your walls, ceilings and floors. 

There are two main methods of spray foam insulation that are commonly used on the market today. They are the following: 

  • Open-Cell Spray Foam – Open-Cell Spray Foam is the lighter, less dense version of the two installation types. Once applied, the expansion is immediate and significant. It can fill large areas quite easily, making it a pretty good choice for large-scale jobs.

    As for the pros, you can expect a high level of soundproofing. The makeup of open-cell spray foam has sound absorption properties that will capture and dampen noise from the outside, leaving your peace undisturbed. Also, it’s a pretty good barrier for air coming into the home.

    As for cons, it, unfortunately, has a couple. For one, it’s not waterproof, meaning water can damage the foam. Another is that it has a lower R-value, meaning that its insulation abilities fall below that of Closed-Cell Spray Foam. Considering insulation is the main point of spray foam, this may be a deal breaker for many. That being said, if the insulation in your home is pretty good, it’s worthwhile to consider whether or not there’s more value in leaning towards the sound absorption aspects.

  • Closed-Cell Spray Foam – Closed-Cell Spray Foam is the denser version of the two. On top of that, it’s a lot more compact, meaning that it doesn’t spread quite as far as open-cell spray foam. This means that it is likely more appropriate for smaller-scale jobs.

    This type of foam has a high level of insulation thanks to its thermal resistance. On top of that, it’s completely impervious to water, meaning that it will not suffer any damage from moisture.

    As an added bonus, closed-cell spray can complement and strengthen the structural integrity of your walls by fusing with them in the damaged cracks. 

There is often talk about spray foam being harmful to homeowners’ health. However, this is not strictly true. Spray foam is only dangerous during the installation process. 

During the installation process, droplets from the spray foam go airborne. These droplets have irritative effects when they land on the skin, which is why Spray Foam installers wear protective clothing to shield themselves. On top of that, inhalation can cause serious respiratory problems. 

When installing spray foam, it’s important to ensure that the area is well-ventilated to reduce the amount of harmful substances in the air. This reduces the chance of them overwhelming the protective measures. It’s also highly recommended that people vacate the premises, including taking their pets, during the process and for a few hours after. 

Once the foam is fully cured, after a few hours, the droplets will be properly dispersed, and it will be safe to re-enter the home. This is because the foam, having hardened, is no longer emitting any gases, entering a state known as “inertness”. 

After this, the health effects are only positive. After all, the spray foam will reduce drafts, moisture and mould growth, allowing you to control the air quality in your home. 

Yes, it can, but it depends entirely on the architecture. 

For example, if a historic home has aspects within the architecture such as solid brick or stone walls, it’s not a good idea to completely seal these areas off. This is because these walls need to breathe. 

Aside from that, however, spray foam can be an unobtrusive and highly effective insulation method. It can fill gaps, crevices and harder-reached areas, and increase the insulation of the area heavily. Older homes typically are built without insulation in mind, and spray foam is a good way to change this. 

Yes. Many find spray foam to be jarring, as it can interfere with the tone and aesthetics of the area in which you are improving. That being said, one thing that remedies this is the ability to paint. However, you must meet the following conditions in order to do this: 

  • Fully Cure the Foam – Whereas spray foam stops emitting harmful chemicals after around six hours, it is not fully cured until around 24 hours after it’s been installed. Ignoring this step means that the paint may not properly adhere to the foam. This can lead to uneven paint, peeling or flaking. 
  • Use Latex-based paint – It can be bothersome for paint to adhere to foam. In order to ensure that it properly attaches to the foam, you should use latex-based paint. Using oil-based paints could cause issues, such as the paint having a reaction that results in bubbles in the paint. 
  • Apply a Primer – Before you actually paint the foam, using a primer may be a good idea, especially if you’re not eager to use latex-based paint. Primers will allow the paint to adhere to the foam much better. 
  • Ventilation – It’s always best to keep the area ventilated. This is because interacting so intimately with the foam could result in some irritative matter coming off the foam, and it’s best not to let it build up. 


No. Spray foam goes some way to preventing condensation, which is good, because condensation can cause mould, which can cause respiratory issues. This is due to the heavy water-resistant properties of the foam, not to mention the barrier that it creates. 

However, it’s important to understand how condensation occurs in order to fully negate it. It is much more a matter of temperature regulation than any form of barrier. This is due to the fact that condensation happens when water vapour, which is the gas version of water, meets a surface that is much warmer than the temperature of the vapour. 

When it comes to water, its transition into liquid, solid and gas are all dependent on temperature (as are many other forms of matter). Whilst low temperatures turn water into a solid (ice), high temperatures can turn it into a gas (think of evaporation or a kettle). 

Condensation mostly occurs when the temperature in the air changes far too quickly. Steady increases and falls in temperature, as well as the ability to keep the temperature consistent, can help prevent condensation – and spray foam insulation is excellent at keeping temperatures consistent in the home. 

Yes. By creating an airtight barrier and limiting the amount of moisture possible, it becomes pretty hard for mould to form in the loft. Mould is formed in water, and can cause people who inhale it respiratory issues. Some health developments have been as severe as pneumonia. 

Two factors for mould to grow are moisture and warmth. In this environment, tiny spores that are invisible to the naked eye travel through the air and land on surfaces. There, they grow. On top of this, mould actually causes a lot of structural issues, and may be part of the reason you get spray foam insulation to begin with – to reinforce against damage already done. 

When dealing with mould, the most important thing is to reduce moisture as much as possible. Whilst spray foam will block moisture coming in, it can’t do anything about moisture that’s already in the air.
