Previously the gaps that were instrumental for preventing dampness are now catalyst to wasted heat from the house and entry of cold air from outside. As a result you need to run energy operated heating system to maintain warmth inside your house. Operating these heating systems result in carbon dioxide emission and excessive spending of energy due to that only to increase spending money in energy bills. On the other hand, insulation installed to your house lowers burning of fossil fuel, CO2 emissions and energy bills.
