Technical - Attic Insulation
There are a number of different products that can be used to insulate your attic. The most common is fibreglass rolls laid between the joists and across the top of the joists to give a finished level of 300mm (12 inches) which achieves the required building regulation U value of 0.16w/m2k.

Attic insulation can also be blown in using Rockwool or Warmcel amongst others. Not all installers will have the facility to use blown attic insulation so check out availability. The main difference with blown insulation is that it is easier to get into the smaller nooks and crannies that are inaccessible to the installer.
