When it comes to enhancing energy efficiency and comfort in homes, choosing the right insulation material is crucial. Advanced insulation offers numerous benefits, helping to maintain indoor temperatures, reduce energy costs, and even improve soundproofing. However, with the vast array of materials available, it can be challenging to decide which one is best suited for your home. In this blog post, we’ll explore the most popular types of insulation materials and compare their features, advantages, and drawbacks.
Insulation is a key component in creating a sustainable and comfortable living environment. Not only does it play a crucial role in thermal regulation, but it also contributes towards reducing a home’s carbon footprint. Here are some common types of insulation materials used in residential properties:
Fibreglass Insulation
Fibreglass insulation is one of the most commonly used types. It’s made from fine strands of glass and is known for its excellent thermal performance and affordability. Available in batts, rolls, or loose-fill, fibreglass is versatile and usable in a variety of spaces, including attics, walls, and floors.
Advantages: Fibreglass is fire-resistant, non-combustible, and doesn’t degrade over time. It’s also relatively inexpensive and easy to install.
Disadvantages: Proper protective gear is essential during installation to prevent irritation. Fibreglass can also settle over time, which may reduce its effectiveness.
Spray Foam Insulation
Spray foam expands upon application, making it ideal for filling gaps and cracks. There are two main types: open-cell and closed-cell. Closed-cell foam is more rigid and provides better insulation, while open-cell foam is more flexible and suitable for soundproofing.
Advantages: Spray foam provides an airtight seal and offers one of the highest R-values, indicating superior insulating power. It’s excellent for reducing air leaks and improving energy efficiency.
Disadvantages: It’s generally more expensive than traditional insulation forms and should be installed by professionals due to its complexity.
Cellulose Insulation
Cellulose insulation is made from recycled paper products, making it an eco-friendly option. It’s treated with a fire retardant for safety and is commonly used in attic spaces and wall cavities.
Advantages: Cellulose is environmentally friendly, offers good thermal performance, and provides excellent resistance to air infiltration.
Disadvantages: It can absorb moisture, which might lead to mould growth. Additionally, it tends to settle more than other insulation types, affecting its effectiveness over time.
Polystyrene Insulation
Available in two forms – expanded (EPS) and extruded (XPS) – polystyrene foam provides excellent insulation for walls and roofs. XPS has a higher density and better moisture resistance compared to EPS.
Advantages: Polystyrene is lightweight, easy to handle, and offers a high insulating value. It’s also moisture-resistant, which reduces the risk of mould.
Disadvantages: While beneficial in many ways, polystyrene can be flammable without a chemical retardant and is less environmentally friendly compared to cellulose.
Mineral Wool Insulation
Made from volcanic rock or steel slag, mineral wool is known for its fire-resistant properties and soundproofing capabilities. It’s commonly used in areas requiring high fire resistance.
Advantages: Mineral wool doesn’t absorb water, provides superior soundproofing, and offers a high level of heat resistance.
Disadvantages: It’s more expensive than fibreglass and can pose health risks if proper handling is not observed during installation.
