Double Bubble Reflective Foil Insulation R Value

Generally the following values are a good.

Double bubble reflective foil insulation r value.

Key benefits of this foil faced double bubble include. In contrast reflectix is always tested as part of an assembly e g. If the product is simply doubled with no air space between the layers a very minimal benefit is obtained r 1 1 per layer for the reflective double bubble. Convection mass air transport conduction by touch radiation.

The r value is dependent upon the type of application used. R value is roughly 6 8 when used in a wall. Insulation s r value is a measurement how much resistance against conduction. Are two layers of polyethylene industrialized air bubbles bonded between exterior.

However we see claims of up to r 14 for some bubble products. R value is roughly 5 3 when used in a floor. Double bubble insulation provides the maximum efficiency and highest r value for bubble insulation. The more airspace in the product the better it is at slowing heat transfer.

R value is roughly 10 6 when used in a ceiling. Heat moves by 3 methods. The r value of foil faced bubble wrap is about one. A simulated wall with 2x4 studs dry wall an air space and layer of reflectix.

Of owens corning fiberglass and r 5 per inch with foamular foam board. Bubble foil does offer some r value because of the bubbles because remember radiant barrier does not have an r value on its own. If you are. 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.

With multiple layers of product and airspaces between each layer enhanced performance will be gained. So by that logic if you wrap ducts with the double bubble foil then you would have your r 6. Our double bubble products are ideal for metal buildings where the control of condensation is necessary. Standard insulation is tested as a material with an r value per inch of thickness for example r 13 for 3 5 quot.

The main one in the latter category is foil faced bubble wrap sold as insulation. If you read the fine print this rating is always achieved as part of an overall assembly which usually includes a lot of dead air spaces. If you install 2 layers of a reflective insulation does the r value double. Double the bubbles for double the airspace.

Any additional r value is achieved by the use of dead air spaces around the reflective product or in used in conjunction with other mass insulation products like fiberglass foam etc. Double bubble insulation is the most effective bubble insulation with highest r value.
