Does Reflective Bubble Insulation Work

Ecofoil reflective insulation will stop 96 of radiant heat which is often overlooked and misunderstood largely due to the fact that r values do not take it into account.

Does reflective bubble insulation work.

Most common thermal insulation materials like fiberglass work by slowing conductive heat flow but reflective insulation works a little differently. When the sun heats a roof it s primarily the sun s radiant energy that makes the roof hot. This type of insulation is designed to reduce radiant heat gain. However radiant heat transfer is responsible for up to 75 of total building heat loss through the roof and 93 of heat that is gained from outdoors into the attic through the roof s surface.

Foil faced bubble wrap is a radiant barrier. Radiant barriers and reflective insulation systems work by reducing radiant heat gain. A radiant barrier reduces heat transfer by radiation and has two excellent applications in homes. Double bubble wrap insulation is very helpful in warding off pests and insects.

Insulation companies who make metallic bubble wrap or their distributors like to boast about their products attributes and often add the equivalent reflective r values to the conductive values giving an overall equivalent r value. Insulation reduces heat transfer by conduction through solid materials. Most common insulation materials work by slowing conductive heat flow and to a lesser extent convective heat flow.
