Mitsubishi Mini Split Heat Pump in Detroit – 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.
Attaching radiant insulation directly to the roof is not effective. If the roof and insulation are in direct contact, heat can pass by conduction even if radiant energy is blocked. Attaching the insulation to the inner rafters creates an air pocket between the roof and the reflective surface for much better results.
In areas where temperatures are high and sunny conditions are common, radiant insulation can help keep temperatures down and reduce the cost of home cooling. Radiant insulation is not effective for keeping heat in during cold weather. In fact, heat from sunlight will not be able to pass through the roof, and home heating costs might even rise.
