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%.
The thicker the loft insulation, the better it will be at reducing heat loss from a building. Thicker insulation provides a greater barrier to heat flow, reducing the amount of energy needed to heat or cool a space. Insulation thickness also impacts the overall energy efficiency of a building and can result in lower utility bills.
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.
Duvets and loft insulation are good insulators because they trap air within their layers, creating a barrier that helps reduce heat transfer. The air pockets in duvets and loft insulation act as a buffer, preventing heat from escaping and keeping the surrounding environment warmer. Additionally, the materials used in duvets and loft insulation are designed to be thermally efficient, further enhancing their insulating properties.
Without loft insulation, heat would escape through the roof of a building, leading to higher energy bills as more heating is required to maintain a comfortable temperature indoors. Additionally, the lack of insulation can result in uneven heating, potential moisture buildup, and a less energy-efficient home.
Loft insulation stops conduction and convection as the insulation which is inserted into the wall cavity prevents the particles of heat energy from traveling through the wall cavity, this stops conduction from taking place. Loft insulation also prevents convection as the cavity insulation stops the air particles from moving, therefore they cannot transfer heat and convection cannot take place.
There is loft insulation to keep in all the warm air from the heater
dependes what type of loft insulation you have
It's used to insulate your loft.
the loft insulation is bad in that house
With no loft insulation you would lose a lot of heat through your loft and be colder, and spend a lot more money on fuel to keep warm in winter.
No, loft insulation should not be installed directly over existing carpet in a loft. Carpets can trap moisture, which may lead to mold and mildew issues, compromising the effectiveness of the insulation. It is important to ensure that the loft space is properly prepared, typically involving the removal of any flooring materials like carpet, to allow for adequate ventilation and proper insulation installation.

Loft insulation is a relatively inexpensive and easy way to save on energy costs. The cost of insulation varies depending on the size of the loft area. Local insulating companies will come to your home and give you a free quote for your insulating needs.
The thicker the loft insulation the less heat escapes! The thicker the loft insulation is the more heat loss will be reduced as if it is thicker the more air is trapped between the layers of insulation and thermal energy cannot pass through trapped air causing it to not leave your home and therefore hating it
