Abstract
A composite article and a method for insulating an appliance are disclosed. In general, the appliance is selected from the group of major, domestic or household appliances (e.g. ovens, stoves, ranges, etc.). The appliance has a first surface that defines a heating cavity, and a second surface opposite the first surface. The composite article comprises a backing layer spaced from the first surface, and an insulating layer sandwiched between the second surface and the backing layer. The insulating layer reduces heat transfer from the heating cavity to the backing layer (e.g. during use of the appliance). The insulating layer comprises a foamed silicone. The foamed silicone can be one formed via a hydrosilylation-curable silicone composition, a condensation-curable silicone composition, or a combination thereof. The insulating layer may comprise a foamed room-temperature-vulcanizing (RTV) silicone. The backing layer comprises a foamed polyurethane (PUR), a foamed polyisocyanurate (PIR), or a foamed PUR/PIR hybrid.
