Loose-fill insulation - Measurement of the thermal resistance; Loesfyllnadsisolering - Laboratoriemaetning av vaermemotstaand

Abstract

SP has reviewed the various types of materials available for use as loose-fill insulation, together with their characteristics. It is important that samples for testing in the laboratory are correctly prepared, in a manner that is representative of their in-situ installation in normal applications. The material must be teared apart and blown out as it would be when being laid normally. Loose-fill insulation materials have been laid in a specially constructed instrumented test roof space, and have also been sprayed and prepared for testing in various test frames used for laboratory measurements. Comparisons have been made between the results of in-situ measurements of materials and laboratory measurements. In addition, the feasibility of taking samples from in-situ materials and preparing them for testing by hand have also been investigated. Comparison of various methods of filling the test frames with loose-fill material by hand and filling them by blowing the material directly into the frames has shown that is feasible to develop a method of preparing samples for testing by hand.Tests have been carried out on five different types of materials: polystyrene beads, two types of glass wool, mineral wool and cellulose fibre. Varying thickness have been used in order to investigate  More>>

Varying thickness have been used in order to investigate the effects of edge conditions. The materials that have been investigated produced different types of characteristic curves when plotting the thermal resistance against thickness. Convection effects * within materials having an isothermal upper surface, * within materials having a non isothermal upper surface (closed surface) and * involving linked convection between/within the material and the airgap (open surface) have been investigated. 21 refs, 24 figs, 30 tabs}
