Problems solved by technology

[0006] However, current RTC silicone sealant compositions, while somewhat effective, still have only a limited ability to prevent the loss of low thermal conductivity gases such as argon from the interior volume of the IGU
As a result of this air permeability, the reduced energy transfer maintained by the gas between the glass panels is lost over time

Embodiment Construction

[0014] The present invention provides an insulated glass unit comprising at least two spaced apart glass sheets in spaced relation to each other, an insulating gas or gas mixture having a low thermal conductivity therebetween and comprising cured (i.e. A gas-tight element of a sealed or vulcanized) sealant composition obtained from the curing of a moisture-curable silylated resin-containing composition containing a moisture-curable formazan The composition of the silylated resin comprises: a) a moisture curable silylated resin which, when cured, provides a cured resin exhibiting air permeability; and b) an air permeability less than that of the cured resin (a) and optionally c) at least one other component selected from fillers, adhesion promoters, catalysts, surfactants, UV stabilizers, antioxidants, curing accelerators, thixotropic agents , dehumidifiers, pigments, dyes, solvents and biocides.

Abstract

The invention relates to a high thermal efficiency, insulated glass unit structure sealed with a cured composition containing, inter alia, moisture-curable silylated resin, the cured composition exhibiting low permeability to gas(es).

Description

field of invention [0001] The present invention relates generally to insulating structures and, more particularly, to a thermally efficient insulating glass unit structure sealed with a room temperature cured composition that exhibits Low gas permeability to gases or gas mixtures. Background of the invention [0002] Room temperature curable (RTC) compositions are well known for use as sealants. In the manufacture of an insulating glass unit (IGU), glass sheets are placed parallel to each other and sealed peripherally so that the space between the sheets or the inner space is completely sealed. The inner space is usually filled with air. Energy transfer is reduced through insulated glass units of this typical construction compared to a single glass panel due to the inclusion of air insulation within the interior space. Energy transfer can be further reduced by increasing the separation between the panels so as to increase the insulating blanket of air. There is a limit t...
