it stops cold air seeping throught little gaps in the roof because cold goes to hot not hot to cold
They both reduce heat loss in the house ;)
Installing insulation in the loft can help to reduce heat loss, lower energy bills, improve comfort levels in the home, and reduce carbon emissions. It also helps to regulate the temperature in the house, making it cooler in the summer and warmer in the winter.
Yes, loft insulation is a good insulator because it helps to reduce heat loss through the roof of a building. It can help to improve energy efficiency and reduce heating costs by trapping heat inside the building.
the loft insulation is bad in that house

Loft insulation prevents loss of heat from your house. So you use less energy to heat your house. As most of our energy still comes from the burning of fossil fuels (coal, oil and natural gas), and because this burning releases carbon dioxide (CO2), a greenhouse gas causing global warming, then loft insulation has a good effect on the environment.

It prevents heat from the house escaping
Insulation impedes the flow of energy. In the case of insulating a loft, this energy is in the form of heat. In the winter, when the inside of the house is warm and outside is cold, the insulation makes it more difficult for heat to escape through the roof. In the summer, the insulation keeps the heat outside the house. The rate of that increased difficulty is called an R-factor, such as R-30 or R-60. The higher the R-factor, the better insulated a house will be. Up to 25% of heat loss in a house occurs through the roof, so in theory, a well insulated loft could reduce heating and cooling bills by 20-25%.
Loft insulation works by reducing the transfer of heat between your house and the outside environment. It acts as a barrier to prevent warm air from escaping your home in the winter and also helps to keep your home cool in the summer by preventing heat gain. This can lead to energy savings and increased comfort in your home.
Loft insulation is used in homes to help reduce heat loss, improve energy efficiency, and lower heating costs. It acts as a barrier to prevent heat from escaping through the roof, keeping the home warmer in winter and cooler in summer.
