Choosing the right loft insulation can be a bit of a puzzle, can't it? You want to keep your home snug and your energy bills down, but with so many options, where do you start? Well, that's where the team at SpotDif comes in. 


Whether you're doing up your loft, tackling a draughty old house, or just keen to cut your carbon footprint, picking the best loft insulation is a smart move. In this blog, we'll walk you through the types of loft insulation and help you figure out which one suits your home the best. Once you’ve worked out which is best for you, use our handy platform to compare loft insulation providers in your local area. We’re here to help you get the best loft insulation for your home at the right price.


Why is it important to choose the correct loft insulation for your property?


Ever wondered why your energy bill shoots up during winter? A lot of it boils down to how well your home is insulated, especially in the loft. Loft insulation keeps heat from escaping, making your home warmer in the winter. Better insulation also keeps your space cooler in the summer — it keeps hot air from outside getting in. 


The right insulation in your loft can save you money on heating bills, reduce your carbon emissions, and even boost your property's value. But different properties are best suited to different types of loft insulation, so it’s important to find the right one for your home. It can mean the difference between a satisfactory solution and the most effective, long-lasting comfort for your home.


Types of loft insulation


So, what insulation types are available? Let’s take a look at the main five types of loft insulation and explore their pros and cons. 


Loft insulation boards


Loft insulation boards offer a sleek solution for insulating your home without compromising on space. These boards are not only good for keeping your loft warm but also add an extra layer of soundproofing, making your home quieter. They are resistant to moisture, which is a significant advantage in preventing damp issues.


Moreover, their durability means they’re a long-term investment, saving you money on heating costs for years to come. They are also easy to cut and fit, so you can tailor your loft insulation boards to any attic shape or size, providing a customised insulation solution that’s both efficient and effective.


Blanket insulation


Blanket loft insulation is favoured for its simplicity and effectiveness. Beyond its ease of installation and affordability, it also offers excellent acoustic properties, dampening noise from outside and between floors. This makes it an ideal choice for busy areas or homes in louder environments. 


Many options are made from eco-friendly, recycled materials, appealing to those looking to reduce their environmental footprint. The fibres used in blanket insulation trap air, keeping your home warm in the winter. On the other hand, blanket insulation can prevent warm air from getting in on those hot summer days. The result?  A versatile insulation option for year-round comfort.


Blown fibre insulation


Blown fibre insulation is perfect for covering every nook and cranny of your loft, ensuring no space is left uninsulated. This method is especially useful in older homes where the structure may not allow for standard insulation sizes. The installation process is fast, causing minimal disruption to your daily life. 


Blown fibre is also adaptable, able to fill irregular spaces that other types of insulation might not reach, ensuring a thorough and complete insulation layer across your attic. This type is often made from recycled materials, making it another excellent choice for eco-conscious homeowners.


Loose-fill loft insulation



Flexible and easy to install, loose-fill loft insulation is a favourite option amongst DIY enthusiasts. Its ability to be easily spread out over irregular spaces makes it ideal for attics with unusual layouts or multiple obstructions. This type of insulation is particularly effective for topping up existing insulation layers, ensuring that your home remains energy-efficient over time.


Additionally, its composition from recycled materials not only makes it an environmentally friendly option but also helps in reducing your home’s carbon footprint. Keep in mind, though, that it may need occasional topping up to maintain its effectiveness due to settling or shifting over time.

Spray foam insulation


Available in two forms — open-cell and closed-cell — spray foam insulation offers a modern and effective way to seal your loft from the cold and heat. When applied, it expands to fill up gaps, cracks, and even the tiniest openings, creating a tight barrier against air and moisture. This method is particularly useful in creating a seamless thermal envelope around your home, significantly reducing the risk of heat loss and improving energy efficiency.


This insulation is known for its durability and longevity, often lasting the lifetime of the house without sagging or settling. However, installation requires professional expertise to ensure safety and the correct application — there have even been advancements in spray foam installation robots! — making it a higher initial investment compared to other types of loft insulation. 


How to work out which is the best loft insulation for your home


Figuring out the best loft insulation for your home involves a few more considerations than you might initially think. Taking the following factors into account can help you navigate towards the best insulation choice for your home. It’s a balance of practicality, cost, effectiveness, and environmental considerations. 


It’s also worth consulting with a professional who can provide you with tailored advice and ensure you choose the insulation that fits your home's needs perfectly.


Let’s look at the key areas to think about when deciding which loft insulation type is best for your needs.


1. Assess your space


First, really take the time to examine your loft. How easy is it to get into? Are you using it just for storage, or do you have plans that might turn it into a living space down the line? Understanding the current and potential use of your loft will greatly influence your insulation choice.


2. Think about performance


The effectiveness of insulation is key. Different materials offer varying levels of thermal resistance. The R-value is your friend here — it tells you how well insulation can resist heat flow. A higher R-value means better insulation, so aim for the best your budget allows.


3. Budget matters


Speaking of budget, while we all want the most effective option, it has to be financially viable. Consider not just the initial outlay but also the potential savings on energy bills in the long run. Sometimes, spending a bit more upfront can lead to greater savings down the line.


4. DIY or professional installation?


This is a big one. Some insulation types, such as blanket insulation are more DIY-friendly than others. However, for more complex options like blown fibre or spray foam, professional installation is not just recommended — it’s necessary for safety and efficiency.


5. Environmental impact


Today, more than ever, we need to consider our choices' impact on the planet. Insulation made from recycled materials or those with a lower carbon footprint during manufacturing can help make your home more eco-friendly.


6. Future plans


Consider any future renovations or changes to your home. Some insulation types can be more adaptable to changes, while others might be more permanent and difficult to modify or remove.


7. Local climate


Your local weather conditions play a significant role in your choice. Homes in colder climates might benefit from denser, more robust insulation types like spray foam, whereas those in milder areas could do well with lighter options.


8. Health and safety


Some insulation materials can have irritants that affect air quality.. If you have allergies, sensitivities, or concerns about indoor air quality, look for insulation that is low in VOCs (Volatile Organic Compounds) to ensure that it doesn’t degrade into particles that could affect your health.
