Radiant barrier VS.Fiberglass insulation or spray foam insulation


1.About Radiant barrier

A radiant barrier is a insulation material that shields buildings from environmental heat and prevents unwanted loss of heat from building inside. Radiant barrier insulation is an effective and cost-efficient way of keeping buildings cool by keeping heat from getting indoor. A radiant barrier are especially useful in where the climates with strong sunlight, which is capable of blocking significant amounts of radiated heat, cheaply and effectively.


Radiant barrier VS.Fiberglass insulation or spray foam insulation

To install a aluminium insulation is more easier and less expensive than install a 6 inch roll fiberglass insulation or spray foam because to install fiberglass between the metal framing and sheeting is not easy, It's really tough having to use a wire mesh to fix fiberglass insulation in place on an steel building. What’s more,Spray foam is not DIY friendly.



Radiant barrier reflects 97% of the heat flow radiant energy, also reflects the heat back from metal building inside . Each unit of radiant heat energy that is reflected away from your building  in the summer, and each unit that is reflected back during the winter, means less operation of your heating and air conditioning system.save money in utility costs. But Fiberglass insulation and spray foam insulation don’t prevent radiant heat transfer.
