Insulation Materials. Insulation materials run the gamut from bulky fiber materials such as fiberglass, rock and slag wool, cellulose, and natural fibers to rigid foam boards to sleek foils.
Bulky materials resist conductive and -- to a lesser degree -- convective heat flow in a building cavity. Rigid foam boards trap air or another gas to resist conductive heat flow. Highly reflective foils in radiant barriers and reflective insulation systems reflect radiant heat away from living spaces, making them particularly useful in cooling climates. Other less common materials such as cementitious and phenolic foams and vermiculite and perlite are also available. Fiberglass Fiberglass (or fiber glass) -- which consists of extremely fine glass fibers -- is one of the most ubiquitous insulation materials. Manufacturers now produce medium- and high-density fiberglass batt insulation products that have slightly higher R-values than the standard batts.

Historical Cohort Mortality Study of a Continuous Filament F... : Journal of Occupational and Environmental Medicine. An historical cohort mortality study of a continuous filament fiberglass manufacturing plant was undertaken to determine whether an elevated lung cancer risk would be observed on a cohort basis.
A nested case-control study of white male lung cancer deaths was incorporated into the study design. An interview survey to obtain information on sociodemographic factors, including smoking, and an historical environmental reconstruction to identify elements in the plant environment to which workers might be exposed were included in the study design. Respirable glass (Beta™) fibers were produced only from 1963 to 1968. The lung cancer odds ratio (OR) among those workers exposed to respirable glass fibers is below unity, as are ORs for exposure to asbestos, refractory ceramic fibers, respirable silica (except for the lowest exposure level), total chrome and arsenic.

Hierarchical Cluster Analysis Applied to Workers Exposures in Fiberglass Insulation Manufacturing. + Author Affiliations Jyun-de Wu.
Author to whom correspondence should be addressed: Tel.: +1 530 754-8164; E-mail: jdwu@epm.ucdavis.edu The objectives of this study were to explore the application of cluster analysis to the characterization of multiple exposures in industrial hygiene practice and to compare exposure groupings based on the result from cluster analysis with that based on non-measurement-based approaches commonly used in epidemiology.
Cluster analysis was performed for 37 workers simultaneously exposed to three agents (endotoxin, phenolic compounds and formaldehyde) in fiberglass insulation manufacturing. Different clustering algorithms, including complete-linkage (or farthest-neighbor), single-linkage (or nearest-neighbor), group-average and model-based clustering approaches, were used to construct the tree structures from which clusters can be formed.
