Does Reflective Bubble Insulation Work

Most common insulation materials work by slowing conductive heat flow and to a lesser extent convective heat flow.

Does reflective bubble insulation work.

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

To be effective the reflective surface must face an air space. Some products say r4 r6 or r8. Most common thermal insulation materials like fiberglass work by slowing conductive heat flow but reflective insulation works a little differently.
