Ceiling Insulation

Ceiling insulation is extremely important, as your ceiling is an area from which heat escapes easily.  Woollen ceiling insuation can prevent you losing up to 45% of your heating and cooling energy through your roof. See more here.

Underfloor Insulation

Floor insulation, particularly in  houses with wooden floors, is critical as an energy saving device. Insulwool underfloor woollen insulation makes houses warmer, healthier and more comfortable, as well as quiet. See more here.
