The Heat Test – Polystyrene Vs Wood Fibre Wall Insulation

Find out more about how we approach this building scenario.

The construction industry maintains that all materials perform equally in terms of thermal insulation. They’re wrong. The following video explains why.

Deciding which material to use when insulating the walls of your home can be difficult. Especially when you’re not made aware of the benefits of using one material over another. There are a lot of options and it can be hard to know which one to choose. Each certainly have their own relative strengths and weaknesses, but only one is capable of high-quality thermal insulation. If the warmth of your home is important to you, we’d suggest you keep reading.

Wood Fibre wall insulation material can be used to dramatically improve the thermal insulation performance of your walls. There are many other benefits to using Wood Fibre materials but one of the most evident is its thermal performance in comparison to other materials.

If you were to compare Wood Fibre with Polystyrene, as we have in the video, you can begin to appreciate the huge difference the choice of insulation can make to your experience living and crucially running your home.

The question is, can you afford to live in a home that loses heat or overheats quickly? If you’re building your own home it’s because you want to live in a space that delivers complete comfort and ease of living. Presumably you’d like to be warm and comfortable and not have to pay huge sums of money to keep it that way?

You’ll consider many things during the process of building your home and make decisions based on what’s important to you. If thermal performance is important to you we’d strongly recommend considering the insulation material you use. The thermal experience of a home is often overlooked during an initial build and although there is always the option to retrofit, it’s far more expensive and disruptive to do so.
