Low smoke, low toxicity carpet

A pressure-sensitive covering having improved fire resistance. The covering, at a minimum, includes a cured layer of an intumescence material having on an inner face a layer of pressure-sensitive adhesive, with the pressure-sensitive adhesive initially being covered by a standard release sheet. To improve the structural integrity of the cured layer before and after intumescence, there may be provided a scrim in the form of an open mesh within the cured layer. To further improve the structural integrity, a base member may be applied between the cured layer and pressure-sensitive adhesive layer. The cured layer may extend peripherally beyond the base member to improve fire resistance. To improve the durability of the covering or patch, there may be provided an overlay in the form of a plastic or foil laminate which extends over the cured resin layer and peripherally beyond the resin layer. The overlay is secured to the resin layer and the substrate by a second pressure-sensitive adhesive which is not necessarily fire-resistant. The overlay will serve to feather the edges of the cured resin layer to reduce damage due to side impact, will reduce damage due to head-on impact, and will provide a shield against moisture ingress to the cured resin layer. Additionally, the pressure-sensitive adhesive for the overlay may have a relatively high bond strength, such that the overlay assists in maintaining the covering or patch in position.
