Foilboard: The Advantages of Using Foil Insulation

Foilboard Green flexible insulated panels are intended for installation on walls, floors, and roofs. They are made in Australia from a fire-resistant polystyrene foam base with solid aluminium foil directly bonded to both sides, resulting in superb insulation, a thermal break, and a non-permeable moisture barrier. Foilboard insulation is being constructed and manufactured to produce a non-itchy, fibre-free structural insulated panel that will deliver sustained thermal efficiency for the structure’s life. It is appropriate for home, commercial, and industrial use.

What Are the Advantages of Using Foil Insulation?

Although purchasing and installing foil insulation has an upfront expense, the advantages often outweigh the investment. The top benefits of multifoil insulation are listed below.

Prevents Heat Loss All Year

All year long, foil insulation can reduce radiant heat loss. In the summer, it may keep heat out by reflecting sunlight. It may reflect heat into an area, keeping it warmer in the winter.

Reduces Energy Costs

Insulation lowers your power bill by making your room more energy-efficient. Depending on the area of your home, installing insulation might save you up to Ā£315 each year. Furthermore, reducing energy use may help safeguard our environment while making your building greener.

A Compact, Space-Saving Solution

Because of its thinness, foil insulation is an inexpensive alternative that can save space. If you have limited space in your roof or ceiling, multifoil insulation is an excellent choice. This makes it ideal for use in tiny areas, attics, and even walls.

Installation Is Simple

In contrast to other varieties of insulation, which need particular tools and can be challenging to handle, multifoil insulation is simple to cut and install with the help of your trusted insulation installers. It is also non-toxic. Thus, no protective equipment is required. It also generates very little mess and requires minor cleanup (unlike foam insulation).

Foil insulation is available in lightweight, easy-to-handle rolls. It is also flexible and may be installed using staples. When working in confined places, you desire to have as few tools as possible, which is why multifoil insulation is the ideal solution.

It May Be Used Practically Everywhere

You can use foil insulation almost everywhere! Aside from aircraft, it also performs well as roof and wall insulation. It’s handy and may be used in various ways, including DIY projects. 

It Lasts for Many Decades

Foil insulation has a lifespan of up to 50 years. As a result, there is no need to change it regularly. This is particularly beneficial for roofing, which can be challenging to fix. It is simple to maintain and built to last. Unlike other types of insulation, Multifoil insulation does not clump, dissolve, or deteriorate with time. It’s a long-term investment that will undoubtedly pay off.

Increase the Value of Your House

Use foil insulation to increase the value of your property by raising the Building Energy Certificate rating. This might be an essential consideration for prospective purchasers.

Keep Condensation at Bay

By preventing warm air from getting into a space, foil insulation helps to avoid condensation. Condensation occurs when heated air collides with cold air, and the molecules can no longer sustain onto the water molecules. Because foil insulation keeps warm air out, a combination of hot and cold air cannot form condensation.

It Can Be Coupled With Other Types of Insulation

Use a hybrid method using foil insulation and various forms of insulation, such as thermal foam, to achieve the most effective insulation possible. In addition, utilise foil insulation to form an impenetrable barrier that keeps moisture at bay. Building codes can be challenging to follow, especially in older structures. However, combine foil insulation with other solutions to achieve optimal efficiency and compliance with these laws.

Where Should Foil Insulation Be Installed?

Foil insulation may be used in a wide range of situations. This is because multifoil insulation is ideal for tiny rooms and regions with limited space. However, it is versatile enough to be used in various constructions. Be guided by your trusted insulation installers if you need a handy person with you or if you can’t do it yourself.

Here are some frequent locations for foil insulation installation:

Insulation for Flat Roofs

The roof loses one-fifth of your home’s warmth. Having adequate insulation may either help or hinder your energy savings. Flat roofs are more susceptible to humidity and require 50mm of vented air space beneath the deck. 

Insulation for Walls

Aside from rooftops, heat may readily escape via walls. Furthermore, foil insulation might aid in heat retention. Pull it tightly and fasten it using cross battens 38x38mm in alignment with the screws.

Conversions of Lofts

Loft conversions benefit greatly from foil insulation. Install beneath roof rafters to produce an airtight insulating layer while protecting against vapour.


Foil works great in extensions as long as you can draw it tight. To fasten it, use 38x38mm cross battens.


By combining the reflecting insulation capabilities of foil and the volume insulation, the foilboard insulates efficiently by producing a radiant shield and a heat transfer break. These characteristics improve the thermal effectiveness of heat transmission via radiation, convection, and conduction.
