Most people are familiar with the term r value when discussing insulation properties.

Tekfoil reflective insulation r value. R value is the m easurement of a materials ability to stop heat transfer. I looked at their site for tekfoil and no where did i see the r value for it given. Measuring the r value of reflective insulation vs.

Reflectix foil insulation e shield low e radiant guard rfoil tempshield eco foil insulation tekfoil reflective insulation energy shield insulation and solar guard vs. All of the radiant barrier appear to be quality products each prevents radiant heat transfer the primary source of heat flow. The higher the r value the more resistant a material or building assemblage is to conductive heat transfer.

Standard insulation is tested as a material with an r value per inch of thickness for example r 13 for 35quot. Standard insulation loses r value. Others i have read about required an air gap on both side of the foil meaning it needed lots of furring strips 1x2s for the purist to suspend it in place.

Tekfoil keeps moisture out and heat in. I think of the foil type of products as reflecting some heat but not of great r value. The r values of reflective insulation and mass insulation are based on the same fundamental equation.

An r value is a measure of an insulation products resistance to thermal heat transfer. For every 1 of moisture absorbed by standard insulation the r value is reduced by 35. In contrast reflectix is always tested as part of an assembly eg.
