Packaged in easy to handle rolls tekfoil insulation r bb r can be used in conjunction with mass insulation or without.

Tekfoil insulation r value.

Great for use in attics and crawl spaces that are poorly insulated as. These r values are a sum meaning this should be the total r value once you add up the entire depth of insulation. Insulation and vapor barrier types reflective bubble bubble reflective r bb r effective under wood concrete vinyl and aluminum siding and is also a perfect for use as a vapor barrier. Standard insulation is tested as a material with an r value per inch of thickness for example r 13 for 3 5 quot.

Use tekfoil over an existing installation for even greater insulation create a radiant barrier using r k or r r and raise the r value on existing insulation. R values themselves don t mean much alone unless they are used to compare the effectiveness of different r. Standard insulation loses r value. For every 1 of moisture absorbed by standard insulation the r value is reduced by 35.

Tekfoil is a patent compliant product. R value does not measure the effectiveness of stopping heat flow by convection up to 25 or radiation up to 93. A higher r value product takes longer to absorb 100 of it s potential and therefore is more effective at delaying the transfer of heat. For example if you have a type of insulation that has an r value of r 5 per inch of thickness you will need a depth of 6 inches of this insulation installed in your attic to reach r 30 if you live in zones 2 or 3.

Conduction is only 10 of the heat flow equation. Of owens corning fiberglass and r 5 per inch with foamular foam board. Reflectix s stated r 14 r values for exterior walls are good only if the reflectix is paired up with r 13 fiberglass batt insulation. All of the radiant barrier appear to be quality products each prevents radiant heat transfer the primary source of heat flow.

In contrast reflectix is always tested as part of an assembly e g. R b r and r bb r tekfoil are perfect for insulating ceilings and walls.
