This is the reason our product has different R-values for different applications (varying amount of air space and heat flow directions). Our stated R-value for a specific application is based on the same test methods of other insulations.

The R-value is the resistance a material has to the flow of heat (the higher the R-value, the greater the resistance). The U-value is the amount of heat that is transferred through a material. (the lower the U-value, the better insulating quality). See similar questions...

Values are calculated using the equivalent thickness method as recommended by the National Concrete Masonry Association (NCMA). See similar questions...

MOS (mean opinion score : standard - P80) is a Metric intended to convey User Experience of Phone Conversation in a single number R-value (standard ? G107) is an objective measurement calculated directly from measurements of packet loss, jitter and delay. It also has a strong correlation with the MOS value. See similar questions...

The R-value of a SIP varies depending on the thickness and type of foam core used. According to a study by Oak Ridge National Laboratory, the "whole-wall" R-value of a wall with a 3-1/2" EPS core is 14 compared to 9.8 for a 2"x 4" wood framed wall insulated with R-11 fiberglass insulation.

The R-value is the measure of the resistance of a material to heat flow (or heat gain) by conduction only. The k-value is the measure of thermal conductivity; it measures the rate of heat transfer by conduction through a material from face to face. ASTEC's thermal conductivity (k-value) is very low (0.00345 W/m ?K or 0.00199 Btu/h ft ?F). A very low k-value indicates a good conductive insulator. See similar questions...

Most residential building codes require a minimum of R-11 in the basement and R-19 in sidewalls. Most commercial codes address the energy efficiency of the building as a whole. This is known as the envelope. NRG Block's higher R-Value allows for trade offs, such as more windows or skylights. See similar questions...

The thermal performance of AAC is equivalent to R-20 insulation. AAC combines the advantages of low thermal conductivity and low air-infiltration with high thermal mass. This product is used in every climatic region of the world, from humid South America, to the dry heat of the Middle East and the severe cold of Finland. Insulation is rarely added; the walls are simply thicker. For more information on thermal performance testing, please see our Energy Efficient page. See similar questions...

The same thing. U-factors are always decimals, the lower the better, and .50 is a good baseline number. R-factors are always whole numbers, the higher the better, and R-30 attic insulation would be a high-performance measurement. In fact, U- and R-values are reciprocals, so you can divide the number one by either to get the other. For example 1 divided by a .25 U-Factor equals R-4; or, 1 divided by 4 equals .25.

You might actually not be using the same model. Not everything that describes the model is in the pdb-file. A typical example are the numbers that describe a bulk-solvent correction. They are not only not documented in the pdb-file, but on top of this, the bulk-solvent corrections used by different programs can be very different. The weighting schemes used by different programs differ substantially and different weighting schemes will lead to different models. See similar questions...

Note: Just because you have RTCP frames being monitored by autoVoIP?, it does not mean they contain QoS information, for example they may just be SDES or BYE RTCP frames, which do not contain QoS. Delay is measured using the DLSR (Delay since last Sender Report) field in the Receiver Report. So both RR and SR frames are needed to measure delay. The fields in the Receiver Report must contain valid information, i.e., not zeros or incorrectly formatted timestamps. See similar questions...

Some states allow for what is call a parallel path method of R-value calculation. Wisconsin and some other states only allow what is called a series parallel calculation. The series parallel is actually the accurate method because it allows for the heat loss in the cross webs of masonry units? R-Value Controversy Back to Top See similar questions...

R-Values of insulating materials are measured in laboratories and are designated a nominal R-Value per inch. In the wall or ceiling of a building most factory-made insulation materials suffer a reduction in performance due to air leakage and infiltration. The insulating value of many building components may be as low as 50% of the nominal R-Value of the insulation they contain. See similar questions...
