Question

Which is a better material for insulation, fibreglass or mineral wool? What are the pros and cons of each? Why is one better than the other? What about the price tag associated with each material?

David · Answer

In brief there is no real difference between fibreglass and mineral wool. The main difference being what they are made of eg fibreglass being made from recycled glass. Mineral wool from natural materials pulverised rock or glass.

As regards which is best, you have to look at the r rating for insulation this is best explained on a government website. The higher the r rating the better the insulation qualities.

If you are looking to install yourself then I would advise you look at sheep wool insulation apart from being natural and greener. The main advantage being in handling the insulation. Sheep's wool is far more easier and cleaner to handle than fibreglass and mineral wool.
