What is Loft Insulation Made From?

Loft insulation material is vast, with many different options to choose from, each with its own advantages and disadvantages. Considering important factors such as effectiveness, application, and budget will help you choose the best loft insulation material for you and your individual needs.  

Read on to explore the different materials for loft insulation, and how to choose the right one for you.  

Choosing the right material for you 

Loft insulating materials include: 

  • Glass fibre  
  • Sheep's Wool  
  • PIR board  
  • Foil-based insulation  
  • Phenolic foam  
  • Stone wool  
  • Wood fibre  
  • Hemp  
  • Recycled polyester  


There are many factors to consider when deciding on the right insulation for your home. The first is the R-value, which measures the material's ability to resist heat flow. The higher the R-value, the better the insulation will be at keeping your home warm in winter and cool in summer.  

Another important consideration is the material's permeability, or how easily water vapour can pass through it. A high-performing insulation should have a low permeability to prevent moisture from accumulating inside your walls and causing mould growth and rot.  

Additionally, the application can strongly impact which material is right for you. You may want something to fit around lots of different obstacles, or just something easy and simple. Loft roll is one of the most common domestic forms of loft insulation. It’s a piece of cake to install; you just roll it along the floor in your loft, and it’s done.  

How much does loft insulation cost? 

The cost of loft insulation will depend on the material you choose, the application process (whether you can do it yourself or need to hire someone) and simply – how much you want to spend.
