What You Need to Understand about Foil Insulation

When it comes to choosing insulation for your property, nowadays, there are many different options to choose from. Whether you’re looking for silver insulation, aluminium foil insulation, or reflective insulation – it’s enough to make anyone’s head spin. Especially when everything you read is full of industry jargon. For this reason, many people settle for the traditional types. People just accept all the mess and awkwardness of fitting that comes with these types of insulation.

However, gone are the days of having to settle for traditional types of insulation. With all this choice at our fingertips, it’s about time we started making informed decisions and took matters into our own hands.

Due to people being familiar with more traditional forms of insulation, such as PIR boards and mineral wool, the newer types of insulation often get overlooked. (New kinds of insulation include methods such as foil wrap insulation or thermal foil insulation). Avoiding these new types of insulation is a huge mistake, as these more unknown types offer a lot more bang for your buck in most cases!

So, what exactly is reflective foil insulation, and what do you need to know about it?

Multifoil Insulation – What is it?

Firstly, multifoil insulation isn’t just a layer of tin foil with some stuffing thrown in for good measure. Multifoil insulation is a high-tech solution made from many layers of reflective aluminium foil, thermo-foam and polypropylene (wadding to you and me). Although multifoil insulation is made from layers, the build-up of the multifoil remains slimline whilst still offering outstanding therm insulation performance.

You can install multifoil insulation virtually anywhere! From roofs, floors, walls, garden buildings, campervans & boats, plus many more!

The multifoil insulation works is by reflecting heat and trapping air between the individual insulation layers, preventing heat loss. By doing this, multifoil insulation allows for a much higher thermal performance using less insulation. As well as that, due to aluminium foils reflective properties, multifoil acts as a radiant barrier. Thanks to this quality, multifoil insulation keeps your home cool in the summer and warm in the winter.

3 Things You Need to Think About Before Choosing Your Foil Insulation

Before you can understand what benefits aluminium reflective foil insulation offers, it’s essential to know what aspects you have to consider regarding the installation process.

The Location 

SuperFOIL insulation is designed to be installed in a continuous layer, rather than being cut to fit between rafters and studs. By installing in this method, not only are you making installation simpler for yourself, but you are also avoiding cold bridging issues and also eliminating gaps in your insulation which could lead to draughts and lack of performance from your insulation. Multifoil insulation is also a fully flexible product, meaning it is easier to use where you have curves/bends unlike more traditional types of insulation.

The Sealing

No, we haven’t spelt ceiling wrong. We are talking about ensuring your foil insulation is fully sealed once in place. By ensuring your insulation is sealed, you will be achieving maximum performance from your foil insulation. Sealing is easy to do with multifoil insulation, done by using foil tape over all joints, gaps, and tears. It takes a little bit of time to do. Still, by completing this, you will notice a considerable difference in draughts throughout your home.

The Cleanup

Multifoil insulation produces very little mess, and practically no waste, unlike foam board which creates an extraordinary amount of both! As well as this, it requires no unique protective clothing or breathing equipment, unlike other types of insulation. Foil insulation contains no irritants, meaning you can handle it without gloves. You could even install foil insulation in shorts and bare-chested if that’s what you fancy!

Is Multifoil Insulation the Solution for Me?

Ultimately this is what matters. Is  thermal insulation foil right for you? We’d like to say YES. Multifoil insulation has a lot of benefits over more traditional types of insulation, and taking advantage of these is something you definitely won’t regret doing.

If you are looking for a bit of quick reading, here is the summary of what foil insulation has to offer!

3 in 1 product – Offering you insulation, a radiant barrier and a vapour control layer or breathable membrane (depending on the product chosen).

Easy installation – the thought of insulating your home may be a daunting one, however, the installation of multifoil is very quick and simple. The insulation is also very lightweight so it is easy to handle, store and move about when needed.

No loss of thermal performance – You won’t have to be worrying about replacing your multifoil insulation anytime soon. Many traditional types of insulations tend to lose their thermal performance over time due to compaction, damage and moisture-related issues. However, with multifoil, this isn’t a concern. Its design will keep it working to the best of its abilities for years to come.

Lower energy bills – by keeping the heat levels in check all year round, rather than just in the winter, so you will see your energy bills reduce in the long run. So the insulation ends up paying for itself as time goes by.

Sustainable – The SuperFOIL products are made from up to 40 % recycled materials and have a lifespan of 50 + years!
