Does Reflective Bubble Insulation Work

Insulation reduces heat transfer by conduction through solid materials.

Does reflective bubble insulation work.

This reflective insulation also reduces your exposure to harmful elements like mildew fungus moulds etc since the plastic foils do not give room for their growth. Double bubble wrap insulation is very helpful in warding off pests and insects. 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. A radiant barrier reduces heat transfer by radiation and has two excellent applications in homes.

Most common thermal insulation materials like fiberglass work by slowing conductive heat flow but reflective insulation works a little differently. Some products say r4 r6 or r8. 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. Most common insulation materials work by slowing conductive heat flow and to a lesser extent convective heat flow.

Foil faced bubble wrap is a radiant barrier. 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. When the sun heats a roof it s primarily the sun s radiant energy that makes the roof hot.
