Description

In cold climates the increased edge-glass heat transfer at the perimeter of a sealed glazing unit creates a special problem. This is where condensed water and frost most readily occur. One mechanism contributing to edge-glass heat transfer is edge-seal conduction. Very few data are available regarding the thermal resistance of the various edge-seal configurations that are commercially available. An experimental procedure has been devised whereby the thermal resistance of an edge-seal can be directly measured using a guarded heater plate apparatus. Results are reported for nine edge-seal test samples. ln addition, results from similar tests provide measured thermal conductivities for four of the materials used in the construction of the edge-seal test samples and commercially available edge-seals.
