An Irish home can lose 20-30% of its heat through its roof, if it is not properly insulated. An under-insulated house is more vulnerable to outside temperature as heat naturally flows from hot to cold. Just like us wearing a hat in winter to stay warm or in summer to help keep us cooler. Attic insulation does not insure that it’s deep enough to be sufficient and you also need to make sure it is not damaged.

Losing heat through the attic harms the environment by increasing greenhouse gas emissions, it also costs you money with higher heating bills.
