What are insulation boards?
Simply put, insulation boards are dense and rigid panels or sheets made from various thermally efficient materials. Depending on the chosen materials and their density, insulation boards can provide a varying degree of thermal effectiveness.
Insulating boards are most commonly made of synthetic polymers such as polyisocyanurate (PIR) or polystyrene (EPS), but there are also plenty of eco-friendly and sustainable options.
Types of insulation panels
Luckily, there is a near-endless range of various insulation panels on the market, tailored to all kinds of budgets and applications. Here’s a summary of some of the most popular insulation boards available on the market today:
- PIR board: Polyisocyanurate boards cost around £5 – £15 per m2, and are one of the most popular choices due to their unrivalled thermal efficiency. PIR exhibits an impressive u-value of 0.022 - 0.028 W/m²K and is relatively sustainable due to zero ozone depletion and low global warming potential. However, they are difficult to recycle and cannot be discarded as bio-waste.
- PUR board: Polyurethane foam insulation panels cost around £5 – £15 per m2 and are another popular material choice. While slightly less effective and sustainable than PIR at thermal retention, a PUR foam insulation panel is notoriously robust and can often last a building's lifetime. They are also resistant to moisture, mould, and rot.
- EPS polystyrene board: Expanded polystyrene boards cost around £10 per m2, making them budget-friendly yet highly effective at heat retention. They’re water resistant, yet vapour permeable, allowing for moisture to evaporate successfully, thus keeping your home and insulation dry.
- XPS polystyrene board: Extruded polystyrene boards cost around £5 - £11 per m2. They are a high-performing thermal insulation board with a closed-cell structure, making them impervious to moisture. They tend to be more durable than their EPS polystyrene counterparts and will often cost more.
- Phenolic board: Phenolic insulation is a rigid type of insulating board with a 95% or more closed-cell structure, making it nearly impervious to moisture. Phenolic insulation is most applauded for its flame and fire resistance, and can sometimes provide slightly better thermal efficiency than even PIR boards.
- Multi-foil board: These insulation foam panels are made from multiple aluminium layers bonded with foam insulation in between, costing an affordable £3 - £4 per m2. While not as effective at heat retention, its affordability makes it an appealing choice.
- Mineral wool: Made from natural or recycled rock or glass products, mineral wool thermal insulation boards cost around £13 - £17.5 per m2. This is a very common and popular insulation material due to its ease of production, thermal effectiveness, and versatility. It also exhibits flame, smoke and mould resistance.
- Corkboard: These all-natural and eco-friendly boards cost around £17 - £22 per m2, and boast a remarkable thermal performance. In addition, they’re very durable, flame and mould-resistant, and entirely biodegradable, making them one of the most sustainable insulation boards on the market.
- Wood fibre board: Made from compressed sawdust and costing around £12 - £24 per m2, wood fibre insulation boards are a sustainable, thermally effective, and breathable insulation material. Due to their micro-porous nature, they're uniquely successful in drying out moisture and reducing condensation.
In addition to the importance of your chosen insulated board, it’s just as vital to work with a professional installer.

How much do insulation boards cost?
The cost of insulation boards can vary depending on your chosen material, its thickness, thermal efficiency and much more. The average cost range for insulation boards is about £3 - £25 per m2, but this can vary significantly.
Here’s a breakdown of costs per m2 based on your chosen insulation board type:
Of all the insulation materials covered, multi-foil insulation boards are by far the cheapest home insulation option, however, it's important to note that multi-foil alone will not provide adequate thermal heat retention, and will need to be coupled with other insulation methods.
Several factors can impact your overall costs that are worth keeping in mind:
- Home condition: Homes with unaddressed issues and outstanding repairs will require maintenance work before insulation can be placed. This includes sealing off gaps, cracks and openings, relocating wiring, clearing debris and much more, adding to your overall costs.
- Insulation thickness: On average you need about 270mm of mineral wool insulation for successful heat retention. Conversely, you only need about 120mm of PIR or other foam panel insulation for the same results. Therefore, the thickness of the material you need will impact your costs.
- Existing insulation: If your home has old outdated insulation in place that needs removing, this will increase your costs. Alternatively, if your existing insulation is healthy but insufficient, you may be able to get away with top-up insulation that is much cheaper.
To make the best decision for your home, we recommend working with a professional installer. That way, a home assessment can be carried out to determine the best course of action tailored to your home.
How thick should panels be?
In general, most rigid panel insulation will require to be around 100mm - 120mm thick to meet UK Building Regulations for heat retention. This is significantly less than what is expected for blanket-style insulation such as mineral wool, which is at about 270mm for optimal insulation.
Ultimately, each property and its conditions will influence what thickness is needed. For this reason, it’s recommended to work with a professional insulation installer who can assess your property and tailor the best course of action to meet your needs.
Pros and cons of insulation panels
To make the most educated decision, it’s important to weigh out the pros and cons of your chosen insulation material. To make things easier, we’ve summarised the key advantages and disadvantages associated with rigid insulation panels for you:
Pros- Effective: Insulation boards such as phenolic, PIR, and cork boards exhibit some of the most impressive heat retention of all materials in the market, making them very effective at lesser thicknesses.
- Durable: Rigid insulation boards are quite tough to damage, making them optimal against weathering, impact, and degradation over time.
- Resistant: Insulation boards boast impressive qualities such as flame, smoke, moisture and mould resistance, keeping your home structure safe and your lives healthy too.
- Expensive: The majority of rigid insulation boards cost significantly more than their blanket-style counterparts like fibreglass and mineral wool. This is due to their thermal resistance capabilities at much lower thicknesses.
- Unsustainable: While there are sustainable options like cork, a lot of insulation boards are made from synthetic polymers that consume lots of resources to produce, are difficult to recycle, and are non-biodegradable. It’s important to choose your materials wisely.
- Less versatile: Due to the brittle and rigid nature of insulation boards, they are not so helpful when insulating awkward shapes and crevices. In comparison, blanket insulation is malleable, allowing it to wrap around uneven surfaces and fit in crevices.
Ultimately, each home situation will be different, which is why working with a professional installer gives you the best chance for a perfect fit.

CONCLUSION
STONE WOOL VS PHENOLIC: WHICH HAS MORE TO OFFER IN THE INSULATION INDUSTRY?
Stone wool and phenolic insulation are both well-established materials with a long history of use in the construction industry. Each offers unique properties that make it suitable for different applications.
Stone wool is known for its excellent fire resistance, and thermal insulation performance. It is made from natural volcanic rock and is highly durable, non-combustible, and resistant to moisture and mold. Its density and structure also contribute to effective acoustic insulation, making it a preferred choice in buildings where noise reduction is important.
Phenolic insulation, on the other hand, is recognized for its outstanding thermal performance relative to thickness. It is a type of rigid foam that offers one of the lowest thermal conductivities of any commonly used insulation material. This makes it ideal for applications where space is limited but high insulation values are required. Additionally, phenolic insulation provides a good level of fire resistance and low smoke emission.
The choice between stone wool and phenolic insulation ultimately depends on the specific needs of your project—whether you prioritize fire safety, acoustic performance, sustainability, or thermal efficiency. Each material has its strengths, and understanding the performance characteristics of both can help in selecting the best option for your application.
WHAT IS THE DIFFERENCE BETWEEN STONE WOOL AND PHENOLIC?
Stone wool and phenolic insulation are two widely used materials in the construction and insulation industries, each offering distinct advantages depending on the specific application. Understanding their differences is essential for making an informed decision when selecting insulation for residential, commercial, or industrial projects.
- Composition and Manufacturing Process
The most fundamental difference between stone wool and phenolic insulation lies in their raw materials and manufacturing processes.
Stone wool, also known as mineral wool, is produced from natural volcanic rocks such as basalt and diabase. These rocks are melted at high temperatures (around 1,600°C) and then spun into fibers, creating a dense, fibrous mat that forms the basis of the insulation. This process results in a highly durable and stable material that is inherently non-combustible and resistant to high temperatures.
Phenolic insulation, on the other hand, is a type of rigid foam insulation made from phenolic resin. During production, the resin undergoes a foaming process that creates a closed-cell structure, giving the material its low thermal conductivity. Once cured, phenolic insulation forms lightweight, rigid boards that offer excellent thermal performance relative to their thickness.
- Thermal Performance
One of the most significant performance-related differences between these two materials is their thermal conductivity.
Phenolic insulation is widely recognized for its exceptional thermal efficiency. It typically has one of the lowest thermal conductivity values among commonly used insulation materials, which translates into a higher R-value per inch. This means that thinner layers of phenolic insulation can achieve the same or better insulating performance compared to thicker layers of other materials. This is particularly beneficial in projects where maximizing internal space is a priority, such as in retrofits or high-performance buildings with strict energy targets.
Stone wool offers solid thermal insulation as well, though its R-value per inch is generally lower than that of phenolic foam. However, it still provides effective thermal resistance suitable for most construction applications, especially when space constraints are less of a concern.
The typical thermal conductivity values are approximately:
Stone wool: 0.034–0.040 W/m·K

Phenolic foam: 0.018–0.023 W/m·K
Taking average values of 0.038 W/m·K for stone wool and 0.020 W/m·K for phenolic foam, phenolic foam has about 47% lower thermal conductivity compared to stone wool, meaning it provides significantly better insulation performance per unit thickness.
- Fire Resistance and Safety
In terms of fire performance, stone wool has a clear advantage. It is non-combustible, capable of withstanding temperatures over 1,000°C, and does not produce toxic smoke or contribute to flame spread. These properties make stone wool an ideal choice for buildings where fire resistance is a key requirement, such as multi-story residential buildings, schools, hospitals, and industrial facilities.
Phenolic insulation also offers good fire resistance—particularly compared to other foam-based materials—and produces relatively low levels of smoke in the event of fire. However, it is not fully non-combustible like stone wool. While it meets many fire safety standards, its use may require additional protective layers depending on local building codes and fire regulations.
- Acoustic Performance
Stone wool excels in acoustic insulation. Its open-fiber structure helps absorb sound waves, making it effective at reducing noise transmission between rooms and from external sources. This makes it a popular choice for applications where sound control is important, such as apartment buildings, schools, and offices.
Phenolic insulation, being a rigid foam with a closed-cell structure, provides limited sound absorption. While it can offer some noise reduction when used in multi-layered assemblies, it is not typically chosen for projects where acoustic performance is a priority.
- Moisture and Vapor Resistance
Phenolic insulation has excellent resistance to moisture absorption due to its closed-cell structure. This makes it suitable for use in environments where high humidity or direct moisture contact is a concern, such as flat roofs or basement walls. It also acts as an effective vapor barrier, reducing the risk of condensation within the building envelope.
Stone wool, while resistant to water and moisture (it does not absorb water and retains its insulating properties when wet), is vapor-permeable. This allows moisture within the structure to escape, which can help maintain a healthy indoor environment when used correctly in a breathable wall system.
- Environmental and Sustainability Considerations
Both materials have environmental considerations. Stone wool is made from abundant natural raw materials and can often be recycled. Its long lifespan and stability add to its environmental benefits, and some manufacturers include high percentages of recycled content in their products.
Phenolic insulation is derived from petrochemical sources, but due to its high thermal efficiency, it can significantly reduce a building’s energy demand over its lifetime, offsetting some of its environmental impact. Additionally, some phenolic insulation products are manufactured using blowing agents with low global warming potential (GWP), making them more environmentally friendly than older foam technologies.
STONE WOOL AND PHENOLIC: STRENGTHS AND WEAKNESSES OF EACH MATERIAL
When it comes to choosing between stone wool and phenolic for insulation purposes, it is important to consider the strengths and weaknesses of each material. Here are some key factors to keep in mind:
Stone wool
Strengths:
-Excellent sound insulation properties
-Resistant to fire and moisture
-Made from natural and recyclable materials
Weaknesses:
-Lower R-value compared to other insulation materials
-Can be difficult to cut and shape
Phenolic
Strengths:
-High R-value for excellent thermal insulation
-Easy to cut and shape
-Resistant to moisture and pests
Weaknesses:
-Can be more expensive than other insulation materials
-Not as effective at sound insulation compared to Stone wool
PHENOLIC OR STONE WOOL FOR SOUNDPROOFING?
Both phenolic insulation and stone wool are used in modern construction to improve building performance, including soundproofing. However, their acoustic properties differ significantly—mainly due to their internal structure and the way they interact with sound waves.
Stone Wool and Acoustic Performance
Stone wool is widely recognized as one of the most effective insulation materials for soundproofing. It is manufactured from natural volcanic rock, melted at high temperatures and spun into dense, open-fiber mats. This fibrous structure is ideal for trapping and absorbing airborne sound waves, making stone wool exceptionally effective at reducing noise transmission through walls, floors, ceilings, and partition systems.
Thanks to its high density and porous structure, stone wool can absorb a wide range of sound frequencies, including mid- and high-range sounds commonly associated with human speech, music, and general indoor activity. As a result, it is frequently used in environments where sound control is a high priority—such as apartments, hospitals, offices, schools, and even industrial facilities.
Phenolic Insulation and Acoustic Capabilities
Phenolic insulation is primarily designed for superior thermal performance. It is a rigid foam material made from phenolic resin and typically features a closed-cell structure. While this structure offers excellent thermal resistance and good moisture performance, it is less effective at absorbing sound compared to porous or fibrous materials.
That said, some phenolic insulation boards can contribute to overall sound reduction when integrated into layered wall or floor assemblies—particularly when combined with acoustic linings, resilient layers, or other sound-dampening components. This makes them useful in certain commercial settings where both energy efficiency and moderate sound control are desired. However, their sound-absorbing performance does not match that of stone wool, especially in applications where acoustic isolation is the primary goal.
Which Material Is Better for Soundproofing?
If soundproofing is the main priority, stone wool is generally the superior choice. Its ability to absorb and dampen sound across a wide frequency range makes it especially effective in reducing echo, reverberation, and airborne noise. It is also naturally fire-resistant, adding an extra layer of safety in acoustically sensitive spaces.
If, on the other hand, thermal insulation is the primary requirement but some level of sound reduction is also needed, phenolic insulation can be considered—especially in systems where other materials contribute to the acoustic performance.
FIBERGLASS INSULATION VS PHENOLIC
When it comes to choosing between fibreglass insulation and phenolic insulation, there are several factors to consider. Here are some of the key differences between the two:
- Thermal performance - phenolic insulation typically has a higher R-value per inch than fibreglass insulation, which means it provides better thermal performance for a given thickness.
- Moisture resistance - phenolic insulation is moisture resistant, while fibreglass insulation can absorb moisture, which can lead to mould and mildew growth.
Ultimately, if you prioritise thermal performance and sound insulation, phenolic insulation may be the better choice. If you're looking for a more affordable option or have environmental concerns, fibreglass insulation may be a better fit.
IS STONE WOOL GOOD FOR THERMAL INSULATION?
In terms of thermal performance, stone wool provides reliable and consistent insulation across a variety of building applications. Its dense, fibrous structure helps to slow down the movement of heat, making it well-suited for use in external walls, roofs, floors, and partition systems. It performs well in both hot and cold climates and retains its insulation value over time, even under varying temperature and humidity conditions.
Aside from its thermal capabilities, stone wool offers several additional benefits:
Fire resistance: It is non-combustible and can withstand temperatures exceeding 1,000°C, making it an ideal choice for enhancing fire safety in buildings.
Sound absorption: Its open-fiber structure helps to dampen noise, improving acoustic comfort in residential, commercial, and industrial environments.
Moisture resistance: Although it is vapor-permeable, stone wool does not absorb water and maintains its thermal performance when exposed to moisture.
Despite its many advantages, stone wool is not without drawbacks. One potential downside is its cost—it tends to be more expensive than some other common insulation materials, such as fiberglass. Additionally, the installation process may require protective equipment, as the fibers can be irritating to the skin or respiratory system during handling.
IS PHENOLIC THE BEST INSULATION?
Phenolic insulation is widely regarded as one of the highest-performing rigid insulation materials available today. It is made from phenolic resin, forming a closed-cell foam structure that offers excellent thermal resistance in a relatively thin profile. However, whether phenolic insulation is the “best” option depends on the specific needs of your project and how various insulation types compare in terms of performance, cost, and sustainability.
Thermal Performance
One of the main advantages of phenolic insulation is its exceptionally high thermal resistance (R-value) per unit thickness. This makes it ideal for applications where space is limited, such as in cavity walls, flat roofs, or internal wall linings. Its thermal performance typically exceeds that of more conventional materials like mineral wool or expanded polystyrene, allowing for thinner build-ups without compromising energy efficiency.
Fire Safety and Moisture Resistance
Phenolic insulation also performs well in terms of fire resistance. It tends to have a low flame spread rating and produces minimal smoke when exposed to fire, making it a good choice in situations where fire safety is a concern. Additionally, it is resistant to moisture absorption, which helps maintain its insulating properties over time, even in humid conditions.
Environmental Considerations
While phenolic insulation offers strong performance, it is not considered the most environmentally friendly option. It is typically derived from petrochemical sources and is not biodegradable. It also does not contain recycled content, which may be a disadvantage for those prioritizing sustainability. In contrast, materials such as cellulose, wood fibre, or sheep’s wool may have a smaller environmental footprint, though they often come with trade-offs in thermal performance or moisture resistance.
Cost and Value
Phenolic insulation is usually more expensive per square metre than other types of insulation, such as fiberglass or stone wool. However, its high R-value means that less material may be needed to achieve the same level of thermal performance, potentially reducing installation space and associated construction costs. For high-performance building designs where space and energy efficiency are critical, the initial investment can be justified.
Conclusion
Phenolic insulation is a high-quality option, particularly where space-saving, fire resistance, and top-tier thermal performance are key priorities. However, it may not be the best fit for every project. Alternatives like stone wool, cellulose, or PIR (polyisocyanurate) may offer better value, improved environmental credentials, or enhanced acoustic performance depending on your specific requirements.
Ultimately, the "best" insulation depends on a combination of factors, including:
- Required R-value
- Available space
- Fire and moisture performance
- Environmental goals
- Budget constraints
Careful comparison of materials and consultation with a building professional can help ensure you select the most appropriate insulation for your application.
WHAT IS THE MOST EFFICIENT INSULATION BOARD?
When it comes to selecting an insulation board for your home or building, there are several factors to consider in order to determine which option is the most efficient. Some of the factors to consider include thermal resistance, cost and ease of installation.
Thermal resistance is a key consideration when choosing insulation, as it measures how effective the insulation is at preventing heat loss. The higher the R-value of the insulation board, the more efficient it will be at insulating your space. Some of the most efficient insulation boards on the market today include those made from polyisocyanurate foam, which have high R-values and are ideal for use in walls and roofs.
Cost is another important consideration when selecting an insulation board, as some materials can be more expensive than others. Polyisocyanurate foam insulation boards are often more expensive than other types of insulation, such as fibreglass or mineral wool insulation. However, they may be worth the investment in the long run due to their superior thermal resistance and energy efficiency.
When it comes to ease of installation, some insulation boards are easier to work with than others. For example, rigid foam insulation boards, such as those made fromexpanded polystyrene (EPS) or extruded polystyrene (XPS), are often preferred by contractors because they are lightweight and can be easily cut to fit irregularly shaped spaces.
Another type of insulation board that is known for its ease of installation is mineral wool insulation. Mineral wool insulation boards are made from natural rock or slag fibres and are available in batts or boards that can be easily installed in walls, ceilings, and floors. Mineral wool insulation boards are also non-combustible and have excellent sound absorption properties, making them a popular choice for residential and commercial projects.
On the other hand, fibreglass insulation boards can be more difficult to work with due to their tendency to shed tiny fibres that can irritate the skin and lungs. Additionally, fibreglass insulation boards can be difficult to cut and shape, which can slow down the installation process and add to labour costs.
Ultimately, the ease of installation is an important consideration when choosing an insulation board, as it can impact both the cost and timeline of a project. By selecting an insulation board that is easy to work with and install, you can save time and money while ensuring that your building is properly insulated for maximum energy efficiency and comfort.
Overall, when selecting the most efficient insulation board, it's important to consider all of these factors and choose a product that meets your specific needs and requirements. While polyisocyanurate foam insulation boards are often considered to be among the most efficient, they may not be the best choice for every project. Be sure to do your research and select a high-quality insulation board that will provide the energy efficiency and cost savings you need for your home or building.
