Just popped into the loft yesterday to see what needs to be done insulation wise. The house is old (about 100 years) its an end terraced to give you an idea. The insuation at present almost looks like (to me anyway) large balls of dirty cotton wool.
What is the best method to add new insulation? Should I attempt to remove the existing insualtion or just lay new insulation over the old? I plan to board over the insualtion at a future date.
Any tips, websites or guidance would be grately appreciated
