According to the department of energy of United States of America, most of the energy consumed by a house is used up in heating and cooling only. About thirty percent of heating is due to air infiltration only. One of the most revolutionary products which have been launched recently is the spray foam which is very good in insulation the house and it also prevents the air leakage.

Basically the air leakage is usually noticed in the months of winters. This is because of the fact that in the winter months there is a large difference of temperature between air inside the house and air just touching the outside walls of the house. This great difference of temperature causes good difference of pressure inside house and outside the house. In turn the pressure difference causes great leakage as air inside the house is at high pressure and air just outside the house is at very low pressure. This heat for which you pay can be checked from leakage by carrying out foam spray in place foam which basically means spraying foam at right place. These foam sprays can save your lots of valuable money from getting wasted.
