Insulation materials

Take the time to choose the right insulation for your home and environment – it will add value and life to your home, and create a healthy and comfortable home to live in for years to come.

Effective insulation works by reducing the transfer of heat through creating a barrier; it traps air within a buildings’ ceiling, under floor and wall layers. The measure of insulation is expressed through an R-Value, the higher the value the more effective the insulation is and the less heat it will let through.

The theory is pretty straightforward, but in reality there are many different types of insulation on the market, each with their own pros and cons. How do you know which is right for you? Different homes and environments will require different forms of insulation, what works for one home may not be practical for another. Here is a quick overview on the main types of insulation on the market today.


The most common and familiar type of insulation. It is made from glass and recycled glass bottles - so it is to some extent, environmentally friendly and sustainable. It offers great thermal performance compared to other materials, but can be irritating to skin and eyes. Some hold concerns regarding the chemicals used in the manufacturing process.

Rock Wool

Rock Wool is made from rocks and minerals, which make it extremely fire resistant without the need to add any chemicals. It resists temperatures up to 1,000°C so it can actually prevent fires spreading. This type of insulation is created in varying types of forms and densities, and can be used in many different applications.


Polystyrene is a very common type of insulation; it is a form of bulk insulation and comes in rigid boards that can be cut to fit any area. Polystyrene has a high R-Value, great moisture resistance and is relatively strong compared to other insulation materials. It can be incompatible with some types of electrical wiring and may actually cause them to erode prematurely.


Aluminium foil relies on its reflective quality and heat conductivity to achieve its insulation performance. Dust and corrosion causes foil to lose its reflectivity over time, so many building codes no longer accept foil by itself as an effective insulator.


Polyester insulation is installed in the form of a large ‘blanket’ that covers the entire roof space. It is often manufactured from recycled plastic so it’s sustainable, eco-friendly and offers great insulation performance without any chemical additives.
