Tekfoil Insulation R Value

Basically a product with a higher r value is better than a simliar product with a lower r value.

Tekfoil insulation r value.

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. A simulated wall with 2x4 studs dry wall an air space and layer of reflectix. Tekfoil is a patent compliant product. These r values are a sum meaning this should be the total r value once you add up the entire depth of insulation.

Keep the heat where it belongs with tekfoil reflective insulation. 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. All of the radiant barrier appear to be quality products each prevents radiant heat transfer the primary source of heat flow. Packaged in easy to handle rolls tekfoil insulation r bb r can be used in conjunction with mass insulation or without.

R values themselves don t mean much alone unless they are used to compare the effectiveness of different r. Standard insulation loses r value. Great for use in attics and crawl spaces that are poorly insulated as. For example the r 6 1 masonry value is only good if you provide two 3 4 inch airspaces one between reflectix and the masonry wall and another space between the drywall and the reflectix.

For every 1 of moisture absorbed by standard insulation the r value is reduced by 35. Standard insulation is tested as a material with an r value per inch of thickness for example r 13 for 3 5 quot. Conduction is only 10 of the heat flow equation. R value does not measure the effectiveness of stopping heat flow by convection up to 25 or radiation up to 93.

R b r and r bb r tekfoil are perfect for insulating ceilings and walls. In contrast reflectix is always tested as part of an assembly e g. 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. Tekfoil reflective bubble bubble reflective insulation is designed for installation between or over framing members on walls floors and ceilings.
