Alpine Heating and Cooling in New York – What Is Radiant Insulation?

Radiant insulation works by reflecting away radiant heat and reduce the costs of air conditioning. The reflective insulation is available in a number of forms, most notably as rolls of foil sheets or as metal shingles. When properly installed, radiant insulation can block heat from the sun’s rays and keep the home cooler.

Heat can be transmitted by three methods. Conduction passes heat from one solid object to another through contact. Convection carries heat through a fluid medium, rising and falling with the temperature until the heat is spread evenly. Radiation is the third method of heat transfer, passing in a straight line from a heat source and warming any object in its path.

Split System Heating and Cooling in New York – Effective Insulation.

Effective insulation from radiant energy depends on three factors: the insulation’s reflectivity; its emissivity, or the amount of heat that passes through; and the angle of deflection. High reflectivity and low emissivity are ideal. The angle is dependent upon installation, and for best results, should be parallel to the roof.

Ductless Heating and Cooling Systems in New York – Dust and Debris.

Often, radiant insulation is affixed to the inner rafters, lining the roof. This not only places the insulation at the best possible angle, it also prevents dust from gathering on the surface. Dust and debris makes the insulation less reflective and less effective.
