Does Reflective Bubble Insulation Work

This type of insulation is designed to reduce radiant heat gain.

Does reflective bubble insulation work.

A radiant barrier reduces heat transfer by radiation and has two excellent applications in homes. To be effective the reflective surface must face an air space. Double bubble wrap insulation is very helpful in warding off pests and insects. When the sun heats a roof it s primarily the sun s radiant energy that makes the roof hot.

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. 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. 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.

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. Foil faced bubble wrap is a radiant barrier. Most common thermal insulation materials like fiberglass work by slowing conductive heat flow but reflective insulation works a little differently.
