Double Bubble Reflective Foil Insulation R Value

The more airspace in the product the better it is at slowing heat transfer.

Double bubble reflective foil insulation r value.

For exact specifications per application contact the vendor. All our reflective double bubble products. In contrast reflectix is always tested as part of an assembly e g. If you are.

Insulation s r value is a measurement how much resistance against conduction. The foil face bubble wrap manufacturers may have a fantastic product but they unfortunately market their product to an industry that is unaware of codes that restrict its use. Any bubble insulation that is approximately thick can only achieve an average r value of 1 to 1 5 on its own. Double bubble insulation provides the maximum efficiency and highest r value for bubble insulation.

Convection mass air transport conduction by touch radiation. Generally the following values are a good. Key benefits of this foil faced double bubble include. The r value of an assembly that includes foil faced bubble wrap could be significantly higher.

R value is roughly 6 8 when used in a wall. If you install 2 layers of a reflective insulation does the r value double. Double bubble insulation is the most effective bubble insulation with highest r value. R value is roughly 5 3 when used in a floor.
