19、ctin-service parameters of minimum thickness, maximum netcoverage per package, and minimum mass per unit area toachieve each listed thermal performance (R-value) level. Chartinformation corresponds to numerous standard R-value levelsrepresenting common building codes, industry standards, orlegislate

20、d requirements (see example in the Appendix X1) andtherefore additional chart columns may be required, that is,number of packages per 1 000 ft2(100m2), and initial installedthickness.5.2 This guide applies to coverage charts for installations inopen, horizontal attic floor spaces. Chart maximum net

21、cover-ages are based upon net floor area; framing area deducted.Sloped ceilings, HVAC equipment and ductwork, and otherfactors can significantly influence product coverage and are tobe considered by the manufacturer.6. Procedures6.1 Three procedures are used to develop coverage chartvalues. The choi

22、ce of procedure used depends on the end useand the type of insulation material being evaluated and theindividual developing the chart. Regardless of which procedureis used, all require thermal conductivity, thickness, and densitymeasurements to have been made before product coverage iscalculated. Th

23、e three procedures are as follows:6.1.1 Select an R-value (usually from a standardized list)and determine what settled thickness will be necessary toachieve the desired R-value. The settled thickness is deter-mined by combining apparent thermal conductivity versusdensity data with settled density ve

24、rsus settled thickness datausing Eq 1. An iterative or trial and error solution is usuallyrequired. Alternatively, a settled density versus R-value rela-tionship is used to determine required settled density, thensettled thickness.R value 5 thickness / l (1)where:l = apparent thermal conductivity6.1

25、.2 Select a settled thickness and determine a correspond-ing settled density. Once the settled density is known, theapparent thermal conductivity versus density equation is usedalong with Eq 1 to determine the R-value for the chosen settledthickness.6.1.3 Select a constant settled density for covera

26、ge chartdevelopment. This method is used for insulation materials thatdo not exhibit significant density change with varying thick-ness. The apparent thermal conductivity value at that density isused in Eq 1 to determine R-value at chosen thickness, or thethermal resistivity is used in equation 2 to

27、 determine minimumsettled thickness at each R-value.Minimum settled thickness 5 R value / thermal resistivity (2)where:thermal resistivity =1l6.2 Coverage Chart Values6.2.1 Select the desired or required chart R-values orminimum settled thickness. Using one of the proceduresdescribed in 6.1, calcula

Once these values are calcu-lated and listed, along with settled density, the followingcoverage chart columns values are then calculated.6.2.1.1 Minimum mass per unit area, lb/ft2(kg/m2), isdetermined by multiplying settled density b
