Multifoil Insulation Guide

Foil insulation, otherwise known as multifoils or multifoil insulation, is the most advanced way of insulating a home or a building. 

What is multifoil insulation?

Multifoil insulation is a type of heat insulation where the material is made from aluminium foil sheets that are sandwiched between thin sheets of foam insulation.

The product was initially designed for domestic buildings, but it also features industrial and commercial projects today. The benefits of this type of insulation include superior performance, regulation compliance, certified quality, and competitive prices. In addition, the thermal efficiency of multifoil insulation exceeds that of traditional systems like rock wool or mineral wool.

Foil insulation actually works better than insulation boards or batt insulation. It keeps your home warm, cosy and comfortable all year long, something that traditional insulation fails to do.

In addition to the obvious energy savings, multifoil insulation also helps with the following:

Building regulations:

With multifoil insulation, you can easily achieve the required building regulations - be it for roofs, walls or floors. They help achieve lower U Values, which means heat loss through the application is restricted, resulting in lesser energy bills.

Saves Space, durable insulation:

Foil insulation lasts up to 50+ years under ideal conditions. Since they are quite thin compared to insulation boards or batts, they save help save space when used for internal wall insulation. 

Besides, with foil insulation rolls, you can easily insulate the nooks and crannies of your home. They are easy to install and can help insulate even the most uneven surface, with ease.

Improved Air Quality:

Unlike wool insulation, foil insulation does not release harmful fibres into the air. The entire installation can be carried out with ease and is almost mess-free. They produce little to no wastage during installation, unlike insulation boards. 

Superfoil SF19+ is made of 11 layers of foil, whilst YBS Superquilt has 19 layers. All these layers are bound using technology and do not come off easily, even when cut. Therefore, if done correctly, installing foil insulation can be a mess-free process leading to cleaner indoors.

Multipurpose:

Foil insulation rolls are versatile in application. They can be used to insulate walls, roofs, floors and cavity walls as well. Foil insulation rolls can be used to insulate almost every corner of the house. They can be used to insulate sheds, garages, vans, campervans, conservatory roofs and much more.

In short, multifoil insulation is a cost-effective and straightforward way to reduce energy bills. It is also easy to help the environment by using less energy. As a result, the material has increased in popularity over the last five years and is still growing in demand. This demand is because it is a practical solution for many people looking for ways to save money, keep their homes warmer, and make them more environmentally friendly.

Cost of foil insulation

Foil insulation rolls are actually pricey when compared to fibreglass or PIR insulation. However, when you compare the labour and other charges that are factored in during the installation of insulation batts or boards, foil insulation, works out to be cheaper.

If you follow the installation manual and manufacturer guidelines correctly, installing foil insulation can be taken up as a DIY project, but only if you are a competent DIYer. Besides, even though they are pricey the cost of installing foil insulation is easily recouped in just a couple of years.

MultiFoil Insulation For Loft:

You can use foil insulation for lofts if you plan for a warm roof. Foil insulation rolls can be used above or below rafters, hence restricting heat loss through roofs. For between rafters, Hybris insulation like Actis hybris) can be used. 

MultiFoil Insulation for walls:Actis Hybris

You can use foil insulation rolls like YBS Superquilt or Superfoil SF19+ to insulate internal walls. YBS can also be used for cavity wall insulation. Additionally, you can use multifoil insulation from Actis insulation's Actis Hybris, Actis H Comtol Hybrid and Actis Boost’R, to insulate walls.

MultiFoil insulation for roof: 

Foil insulation can definitely be used to insulate roofs. On a pitched roof, they can be used to insulate below and above rafters. Multifoil insulation panels like Actis Hybris can also be used to insulate in between rafters.

MultiFoil insulation for radiators:

Foil insulation can actually be applied behind radiators, as they will reflect the radiant heat back indoors. This minimises any heat loss through the walls or spaces nearby.

Installing multifoil Insulation

Foil insulation can be a DIY project, but only if you are an efficient DIYer. Follow the manufacturer guidelines and also refer to the guidelines and installation videos available. We advise that you best contact professional insulation contractors for installing foil insulation. 

How Does Multifoil Work?

Multifoil insulation has the potential to save up to 20% on energy bills. It's made from a highly reflective foil layer and a high-performance, low-conductivity foam core. The foil reflects heat into the room during winter and minimizes heat escape in summer by reflecting light. 

The low-conductivity foam core provides excellent thermal insulation to keep your home comfortable all year round.

What Are The benefits of Multifoil?

The benefits of multifoil insulation are many. It's a cost-effective, easy-to-install, and environmentally friendly alternative to traditional insulation. Multifoil insulation also has high thermal performance and low embodied energy. This performance is due to its being made up of many layers which all work together to reflect heat back in or out of the structure depending on its intended purpose.

The Building Regulations 2010 Part L Section A2 recommends multifoil insulation as an alternative insulator for cavity walls and roofs, where permitted by the local Building Control Department. Using multifoil insulation, you can save on your energy bills by cooling or heating your home more efficiently.

How To Install Multifoil

There are a few different ways of installing multifoil insulation, with some methods requiring more time and labour than others. The most common form of installing this type of insulation is by rolling the sheets onto the ceiling or walls and attaching them with a staple gun or adhesive strips.

Multifoil insulation is often installed professionally.

In Conclusion:

A step up from the routine batts and boards, foil or multifoil insulation is becoming increasingly popular for home insulation. They prevent heat loss, help meet building regulations and keep your home warm and cosy throughout the year.
