How does open-cell spray foam work?
Open-cell spray foam insulation works wonders in properties by creating a seamless thermal barrier. When applied, this type of insulating foam expands to nearly 100 times its original volume — filling any pesky gaps and crevices with ease.
This expansion ensures a snug fit in walls, ceilings, and hard-to-reach areas to significantly reduce air leakage. Specifically, the open-cell structure of the foam allows it to be highly effective at trapping air, which is key to its insulating properties. It not only keeps warm air in during colder months but also helps maintain cool air in warmer seasons, resulting in a comfortable, energy-efficient home — all year round.
What is the difference between closed-cell and open-cell spray foam?
Closed-cell spray foam is denser and more compact, offering a higher R-value — a measure of thermal resistance — per inch, making it ideal for outdoor or damp environments due to its moisture resistance.
Open-cell spray foam is lighter and more expansive, making it excellent for indoor use. Open-cell spray foam provides superior sound dampening and cost-effectiveness — but, it has a lower R-value and is therefore less resistant to moisture in comparison to closed-cell foam.
Can I apply open-cell insulation myself?
While applying open-cell insulation in a DIY style is possible, it requires careful consideration. Open-cell foam insulation kits and open-cell spray foam kits are available, they are generally more suited for small projects or touch-ups rather than whole-house insulation. These kits contain the necessary components but using them effectively demands a certain level of skill and understanding of expert insulation techniques.
Safety is paramount in these cases, as improper application can lead to issues like uneven insulation or even health hazards. For larger or more complex projects, professional installation is recommended to ensure optimal performance and safety of your open-cell foam insulation.

How much does open-cell insulation cost?
In the UK, the cost of open-cell insulation can vary widely based on several factors. On average, homeowners might expect to pay between £20 to £50 per square meter. However, this is a rough estimate, and actual costs can differ.
Property size and layout — Larger properties or those with complex layouts may require more materials and labour.
Insulation thickness — Thicker layers of open-cell foam offer better insulation but this will increase the cost.
Location and accessibility — Hard-to-reach areas can complicate the installation process, potentially raising the price of your open-cell spray foam.
Existing insulation removal — If you have old insulation that needs to be removed, this will add to the overall cost due to the extra labour and skill involved.
Remember, investing in open-cell loft insulation can lead to significant energy savings over time, offsetting any initial expenses. Always remember to consider both upfront costs and long-term benefits when evaluating the price of your open-cell insulation.
Is open-cell spray foam any good?
Open-cell spray foam is a highly effective insulation choice, offering numerous advantages for homeowners like you. Let's delve into the benefits of open-cell spray foam a bit more to understand its value:
Enhanced energy efficiency
Open-cell foam insulation is stellar for creating an airtight seal, drastically reducing potential air leakage. This leads to less strain on your heating and cooling systems, promoting a more energy-efficient home with potentially lower utility bills.
Superior sound dampening
One of the standout qualities of open-cell spray foam is its ability to absorb sound. This makes it excellent for reducing noise pollution, whether it's external noises or sounds between different rooms and floors within your home.
Improved indoor air quality
By sealing off gaps and cracks, open-cell spray foam prevents dust, pollen, and other airborne pollutants from entering your home. This can significantly enhance indoor air quality — amazing news for any allergy sufferers.
Flexibility in application
Thanks to its expansive nature, open-cell foam can easily reach and insulate difficult-to-access areas like corners, edges, and around wiring, ensuring comprehensive coverage.
Moisture management
While less moisture-resistant than closed-cell foam, open-cell insulation still offers some level of humidity control. Its permeable structure allows for breathability, helping to manage undesirable moisture levels within the home.
With all this in mind, open-cell spray foam insulation is indeed a good choice, particularly if you prioritise energy efficiency, soundproofing, and overall home comfort.
What makes open-cell spray foam better than other insulation options?
Open-cell spray foam stands out from other insulation options thanks to its unique combination of features.
Its expansive nature ensures thorough coverage, even in hard-to-reach areas, creating an airtight seal for enhanced energy efficiency. Additionally, its excellent sound-dampening properties offer a quieter indoor environment.
Plus, it's more cost-effective compared to some alternatives, providing a balance of performance and affordability that's particularly attractive for indoor residential insulation needs.
What are the downsides of spray foam insulation?
While open-cell foam insulation offers many benefits, as with anything, it's not without its drawbacks.
Key open-cell foam insulation problems include a lower R-value compared to closed-cell foam, making it less effective in extreme temperatures. Additionally, it's less moisture-resistant, potentially allowing for higher humidity levels within walls.
Improper installation can also lead to uneven coverage, and the foam may shrink or degrade over time, affecting its insulating properties. It’s also important to consider that incorrect spray foam installation may affect any mortgages or surveys that you have on your property. So, when we say it’s recommended to get an accredited professional to install your spray foam insulation — we mean it! Compare trusted spray foam installers today with SpotDif.
How long does open-cell spray foam last?
Open-cell spray foam insulation is renowned for its longevity, typically lasting the life of your building upwards of 20 to 30 years. However, several factors can minimise its effectiveness over time.
For instance, exposure to high humidity levels can affect its structure, reducing its insulating capabilities. Improper installation can lead to uneven expansion or gaps, also compromising its effectiveness.
Additionally, mechanical damage or pest infestations can degrade the foam, impacting its performance. Regular inspections and proper maintenance are crucial to ensure that open-cell spray foam insulation retains its effectiveness throughout its intended lifespan.
Open-cell spray foam care and maintenance
Maintaining open-cell spray foam insulation is crucial for ensuring its long-term effectiveness. In light of this, here are some tips to help you care for your open-cell spray foam.
Regular inspections: Periodically check your open-cell spray foam insulation for any signs of damage, such as shrinkage or cracks, as this can compromise its insulating properties.
