It is very basic principle and rule of nature that molecules move from hot areas to cool one. And hot air blows and is replaced by the cold air always.Hence, if the area you are living is surrounded by cool environment the heat you have generated to keep your room or home warm will move in the direction of cold area and will replace it.
In a home it is usually done through various major ways like doors, windows chimneys and many more, but if all of these are sealed there are still some hidden ways that heat can find to escape, these are known as lofts.
These lofts are most of the time found in roof. So in loft insulation it becomes so difficult for the hot energy or heat to escape from it as it does not allow any heat to pass and become resistant against its passage. This is done with the help of a loft material which is filled with some air thing called air pockets.
These air pockets reduce the U value of the loft present anywhere in the roof. This U is actually the value that calculated to know that how instantly and in what range a roof can loose the energy. The mathematical survey calculation is ranged between 2.3 to 0.16 W/m2 k, which means that it will only allow up to five percent of heat loss and remaining ninety five will be restricted.
On the other hand some professionals use R-value which on contrary give inverse of the calculations made by the U value’s calculated. It also has a constant value of approximately six to seven km2/W. these lofts are necessarily recommended by the governments and NIA recommendations and the values that are to be used here are R-values.

A note on loft insulation
The effects of the climate changing day by is day is being noticed by everyone. The weather all around the world has become very unpredictable and everyday people are noticing the effects of global warming.
Today the winters are getting colder and the summers are getting hotter not to forget the problems people are facing due to shortage of water all around the world.
Thus the question arises on how we as a nation can help reduce the carbon footprints?
Statistics show that the energy that we use in our houses is one of the main reasons for the release in carbon emissions. In countries that experience extreme cold climatic conditions, it has been shown that the carbon emissions are a lot due to the constant use of the heater during the winters.
One way to help reduce the carbon emissions as well as the fuel bills is by reducing the temperature of the heater or by installing a boiler which is very effective and suits your requirements. Another method can be by installing a loft in the places where the chances of the loosing heat is more like the roof.
In the past loft insulation was considered as a dirty and difficult job which was done best by professionals. This used to turn out to be very expensive and not everyone could afford it.
Today it has become very easy to install the loft as it is found in the form of a blanket. One of the main advantages with a loft blanket is that it is totally encapsulated which helps to ensure that the materials within the blanket stays there itself and the installation is very easy resulting to the fact that there is no need of any protective eye gear or clothing during the time of installation.
