This book was released on 1963 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: This program encompasses an analytical and experimental investigation of the thermal properties of high temperature insulation materials. Effective thermal conductivities of graphite and zirconia fibers were measured in the temperature range of -320 to 200 F. The results were compared with empirical and theoretical models of heat transfer in fibrous insulations. Measurements of visible and infrared transmission through insulation materials indicated that scattering is the principal mechanism of radiation attenuation. Scattering and absorption cross sections estimated from the transmission data are given and show little effect of insulation temperature. The effective thermal conductivities of evacuated insulation systems were measured in the temperature range from 60 to 4000 F. The stability of materials exposed to high temperature vacuum environment for up to 170 hours was studied.

Bomberg and published by Division of Building Research, National Research Council of Canada [i.e. National Research Council Canada]. This book was released on 1980 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The customer for cellulose fibre insulation (CFI) has only two basic requirements: that the insulation provide the desired thermal resistance for the service life of the building; and that its use does not increase the hazard to health or contribute to the deterioration of other building components. An analysis of the requirements for CFI used as attic insulation is given in Table I. The thermal resistance provided by CFI is basically a function of its thickness and density. However, the thermal conductivity is almost independent of the density, in the density range at which the material is normally applied, i.e., 30 to 55 kg/m3 . There is a certain, relatively small range of variability, depending on paper grinding, the paper stock used, and the chemicals added, etc., but the thermal conductivity of all CFI material is practically the same. Research on CFI has led to the development of a number of test methods to determine the density and density changes during service life, and hence the resistance that will be provided by a given mass of material. In these tests, an accurate estimate of settlement is required because, in the field, CFI blown at a relatively low density will generally settle under the influence of such factors as temperature and humidity variations, and building vibrations. The test for density determination in Specification 51-GP-60M,8 of the Canadian Government Specifications Board (CGSB) is performed by blowing the material at machine settings selected to produce a minimum density. The "design density" is then calculated by Method A - from the blown density and the settlement determined by a drop test plus a temperature-humidity cycling test; or by Method B - from the blown density multiplied by a factor of 1.27, which is determined by averaging the settlement observed for tests on several materials. The manufacturer is required to label the bags or containers with the weight of the material and the area coverage for various resistances. The design density must therefore be predicted quite accurately if the "resistance coverage" values listed are to be realistic because the resistance provided depends mainly on the final thickness achieved. This implies two testing requirements: a test for quality assurance to ensure that the customer gets the resistance expected; and a quality control test that the manufacturer can use to ensure that he is producing a uniform material according to the specification. This Note will examine the precision of the various methods that determine design density in terms of their repeatability and reproducibility, and will discuss the effect of material variability.
