Choosing the right insulation for the outside of your home can be a difficult decision. With so many different types available, it can be overwhelming to decide which one is best for you. In my experience, the four most common types of external insulation are mineral fibre, EPS, phenolic, and wood fibre. In this article, I will explain the features of each type and how they differ, to help you make the best decision for your home.
EPS Insulation:
EPS insulation, or Expanded Polystyrene, is a lightweight and easy-to-install option for external insulation. It is made from foam beads and is a popular choice for those who want a quick and simple installation process. This is a good choice for those on a budget.
Mineral Fibre Insulation:
Mineral fibre insulation is made from rock or slag wool and is a popular choice for external insulation due to its effectiveness. Slightly more expensive than EPS it provides good insulation performance. As of 2023 there is a shortage of this option with long lead times.
Wood Fibre Insulation:
Wood fibre insulation is made from wood chips and is a great option for those who want a natural and sustainable insulation material. It is an eco-friendly option that is easy to install and has good insulation properties.
To help you understand the differences between these four types of insulation, I have created the following table:
| Insulation Type | Affordability | Ease of Installation | Thermal Performance | Environmental Sustainability |
| Mineral Fibre | Affordable | Easy | Good | Average |
| EPS | Affordable | Very Easy | Average | Poor |
| Wood Fibre | Expensive | Easy | Good | Excellent |
As you can see from the table, each type of insulation has its own strengths and weaknesses. If you are on a tight budget, EPS insulation is a good choice, while those who are more environmentally conscious may prefer wood fibre insulation. If you want a high-performance insulation material, mineral fibre insulation is the best option, while EPS insulation is the easiest to install.
In conclusion, choosing the right insulation for the outside of your home requires careful consideration of your needs and priorities. By understanding the features of each type of insulation and their differences, you can make an informed decision that will help you achieve the perfect balance of affordability, ease of installation, thermal performance, and environmental sustainability.
