Straw bale insulation is an excellent form of material that can be used as an alternative to other more conventional types of insulation such as rockwool, cellulose or fibreglass. 

One of the major benefits is that straw bales are cheaper than these materials and, sometimes, can be obtained from local farmers for free, as well as from specialist suppliers at a reasonable price.
