Tailoring your insulation choice to your specific climate needs can help you optimise your energy efficiency accordingly.

Another factor to consider is cost. There are plenty of budget-friendly types of insulation that are easy to install, making them popular choices for those looking to improve energy efficiency without breaking the bank. Whatever type you choose, it’s important to keep your long-term savings in mind when choosing the right insulation for you and your home.

For those who want to factor in sustainability, again there are lots of options that offer thermal efficiency, sound insulation properties and a reduced carbon footprint. So if you choose eco-friendly insulation, you can not only enhance your home’s thermal performance, but also contribute positively to the environment.

What are the different types of insulation?

As mentioned, insulation is available in various forms and materials, each with its own unique properties and applications. Below are some of the most popular types of insulation available.

Blanket insulation

Blanket insulation, also known as batt or roll insulation, is one of the most common, traditional and cost-effective options available. It’s made of flexible fibres, such as fibreglass or mineral wool, that are formed into rolls or batts.

It’s one of the many types of wall insulation but it can also be used to insulate ceilings and floors in both residential and commercial buildings. It’s relatively easy to install and can be cut to fit around obstacles such as electrical wiring and plumbing. 

One of the most versatile options on the market, blanket insulation offers good thermal insulation properties and provides acoustic insulation, reducing noise transmission between rooms.

Rock mineral wool insulation

Rock mineral wool insulation, also known as stone wool or rockwool insulation, is made from natural rock materials like basalt or diabase. It’s manufactured by melting the rocks at high temperatures and then spinning them into fine fibres.

One of the key advantages of rock mineral wool insulation is its excellent fire resistance. It’s non-combustible and can withstand high temperatures without melting or releasing toxic fumes. This makes it a safe choice for insulating areas where fire protection is a priority, such as walls, ceilings, and floors.

In addition to its fire-resistant properties, rock mineral wool insulation also provides thermal and acoustic insulation by absorbing sound, reducing noise transmission and improving acoustics within a space. This type of insulation is a reliable and versatile option for any property, offering excellent fire resistance and thermal performance.

Sheet loft insulation

Sheet loft insulation, also known as rigid loft insulation, is a type of insulation that comes in rigid boards or panels. It’s typically made from materials like expanded polystyrene (EPS), extruded polystyrene (XPS), or polyisocyanurate (PIR).

Sheet loft insulation is designed to be installed between and over the rafters in the attic or loft space. It provides a continuous layer of insulation, helping to reduce heat loss and improve energy efficiency. It’s particularly effective in areas with limited headroom or where traditional insulation methods are not suitable.

One of the main advantages of sheet loft insulation is its ease of installation. The rigid boards can be cut to size and fitted tightly between the rafters, ensuring minimal gaps and maximum performance. It can also be used in conjunction with other insulation materials to achieve higher levels of insulation. Some other benefits include enhanced acoustic insulation and moisture resistance.

Loose-fill insulation

Loose-fill insulation is a type of insulation material that is installed by pouring or blowing it into hard-to-reach or irregularly shaped areas. It consists of small particles or fibres made from materials like cellulose, fibreglass, or mineral wool.

It’s particularly useful for insulating areas such as attics, walls, and floors where traditional insulation methods are challenging. It can be poured or blown into cavities, gaps, and voids, filling them completely and providing thermal insulation. The installation process for loose-fill insulation involves using special equipment, such as blowers or machines, to distribute the material evenly.

Sprayed foam insulation

Sprayed foam insulation, also known as spray polyurethane foam (SPF) insulation, is a versatile and effective type of insulation. It’s applied as a liquid and expands into a foam that fills cavities and gaps, providing insulation and creating an air-tight seal.

One of the key advantages of sprayed foam insulation is its superior air sealing properties. The foam expands and adheres to surfaces, filling all cracks and crevices, preventing air leakage and reducing heat loss. This helps to improve energy efficiency and reduce energy costs.

Sprayed foam insulation also offers excellent moisture control. The foam creates a barrier that prevents the entry of moisture and helps to eliminate condensation within the walls or roof. This can help prevent mould and mildew growth and protect the structural integrity of the building.

Structural insulated panels

Structural insulated panels (SIPs) are a modern and energy-efficient type of insulation. They consist of two layers of rigid insulation material, usually expanded polystyrene (EPS) or polyisocyanurate (PIR), sandwiched between two layers of oriented strand board (OSB) or other structural sheathing.

SIPs are prefabricated and can be used for walls, roofs, and floors. They offer excellent thermal insulation properties, reducing heat transfer and improving energy efficiency. The continuous insulation provided by SIPs helps to eliminate thermal bridging, which can contribute to heat loss.

One of the advantages of SIPs is their structural integrity. They provide excellent load-bearing capacity and can be used as a substitute for traditional timber framing in construction. SIPs also offer fast and efficient installation, as they are prefabricated and can be easily assembled on-site.

In addition to their thermal and structural properties, SIPs also provide good sound insulation and have a low carbon footprint, making them a sustainable choice for environmentally conscious homeowners.

Sheep’s wool insulation

Sheep’s wool insulation is a natural and sustainable option for insulation. It’s made from the fleece of sheep and is treated to make it resistant to pests and fire. It offers excellent thermal insulation properties, helping to reduce heat loss and improve energy efficiency. It can also absorb and release moisture, providing effective moisture control and preventing condensation.

One of the advantages of sheep’s wool insulation is its ability to regulate indoor temperatures. It can absorb excess moisture when humidity is high and release it when humidity is low, helping to maintain a comfortable and healthy indoor environment.

Sheep’s wool insulation is also a sustainable choice, as it’s renewable and biodegradable. It has a low environmental impact and a low carbon footprint, making it an eco-friendly option for insulation.

Rigid foam insulation

Rigid foam insulation is a type of insulation that comes in rigid boards or panels. It’s usually made from materials like expanded polystyrene (EPS), extruded polystyrene (XPS), or polyisocyanurate (PIR). It provides high thermal resistance and has a high R-value. It offers excellent thermal insulation properties, reducing heat loss and improving energy efficiency.
