R-value is an assigned number derived from a specific testing procedure to determine a materials (or building assemblage) "resistance to conductive heat transfer". The higher the R-value, the more resistant a material (or building assemblage) is to conductive heat transfer.

No. Products with R-values reduce rates of "conductive" heat transfer and are tested for this characteristic. Radiant Barriers provide benefit by dramatically reducing "radiant" heat transfer which is just as quantifiable but not related to R-value type performance. See similar questions...

No. Our products do not operate in this manner. Minimal benefit is netted when the product is doubled. See similar questions...

R Value - the measurement of 'insulating ability' of the material. The higher the R Factor number the greater the insulation value. U Value - the measurement of 'heat loss' through the material. The lower the U Value the less heat is escaping. See similar questions...

A NRG Block is six to ten times higher in R-Value than a common block, which ranges from 1.5 to 2.5 depending upon the aggregate used. See similar questions...

Other blocks using inserts or hollow core blocks with poured insulation range between 5 and 6 for a 9 and 10" block. See similar questions...

R-value is a standardized measurement of thermal efficiency. The higher the R-value, the greater the insulating properties. Overhead Door manufactures insulated doors with a broad range of R-values designed to meet your needs. Our Thermacore® doors offer our highest R-values - up to 17.5. See similar questions...

The signal from the transducer is amplified by a bandpass-filter/amplifier, followed by another bandpass filter/log-amplifier, followed by an integrator with gain, followed by an analog to digital converter integrated in a microcontroller. For the LV-MaxSonar®-EZ1™ we increased the gain in the log section of the chain and decreased it in all other areas, as compared to the original MaxSonar®-EZ1™. See similar questions...

The MaxSonar®-EZ1™ or the LV-MaxSonar-EZ1 will detect a person (an acoustically soft target) to 8 to 10 feet or more. See similar questions...

The R-Value is formulated using an inch of thickness as a measure. Due to the fact that Nansulate is made to go on in a thin layer - less than an inch thick - an accurate R-Value cannot be calculated for it. Nansulate works by acting as a barrier to heat transfer. It does not only insulate by trapping air, as other insulations do. Nansulate’s effectiveness can be seen in this energy savings demonstration, which shows how it can effectively insulate and slow down heat transfer. See similar questions...

That's a good question, but unfortunately the answer is not so simple, Window thermal performance is measured as a U-Value which Is the reciprocal of the R-Value ( R-Value = 1/U-Value. For example. R 2 = U .50, or 1/.50 = 2) A bit of background: the R-Value measures the resistance to heat loss or gain, while the U-Value measures the transmittance of heat through a material. The higher the number in R-Value the better the resistance, so the better the insulating value. See similar questions...

R-value and U-value are reciprocal to one another. The term U-value is measured by the amount of heat that escapes a surface-a wall, ceiling, or window. R-Value is measured by insulation value. How many glass layers there are in a window to the type of gas that is between the panes of glass, are some of the basis of this measurement. The higher the R-value, the better insulated are walls and ceilings. The lower the U-value, the better job a window does in keeping out heat and cold. See similar questions...
