Attic Insulation

Attic Insulation

Does your home get cold as soon as you turn the heating off? If the answer is “Yes” it means that your home is not retaining the heat. This is normally due to poor insulation in your home.

Attic insulation can help reduce your heating bills by as much as 70%. When your home is well insulated it will hold the heat in for longer, which means that you will need to turn your heating on less than before. Some people have reported cutting their use of oil/gas down to 2 hours per day in winter after installing spray foam attic insulation. Good attic insulation has a positive effect on the environment as well as your wallet. You will need to use less damaging fossil fuels to keep your home warm!

Types of Attic Insulation


There are different types of insulation that you can use in your roofing. Each type of insulation has a different insulation value or U-Value - the lower the U-Value, the better the insulating material. Typical insulation in an attic should be more than 20-30cm thick unless you are using more advanced thinner materials. Here are a few of the most common types of insulation

  • Fibreglass – Fibreglass is made from molten glass spun into microfibers. It is probably the most commonly used form of roof insulation.
  • Rock Wool – Rock wool is made with molten rock instead of glass.
  • Cellulose - made from shredded recycled paper.
  • Eco insulation - this can be made of a range of recycled materials, such as plastic bottles or paper.
  • Reflective foil thin insulation – this type of insulation is thinner than regular insulation, it has many layers of foil with fibrous material in between
