The present disclosure relates generally to flame retarding building materials and methods for making them. More particularly, the present disclosure relates to flame retarding building materials that have both flame retardant character and desirable water vapor permeability values. In one embodiment, the disclosure provides a flame retardant vapor retarding membranes comprising: a building material substrate sheet having a melt viscosity of about 1 Pa.Math.s to about 100,000 Pa.Math.s at about 300° C. at 1 rad/s; and a polymeric coating layer disposed on the building material substrate layer, wherein the coating layer has a melt viscosity of about 1 Pa.Math.s to about 100,000 Pa.Math.s at about 300° C. at 1 rad/s.

A flame-retardant cable having a core is disclosed. The cable contains at least one conductor and a coating made from a low smoke zero halogen flame-retardant polymer composition. The polymer composition contains a halogen free base polymer added with a) less than 170 phr of at least one metal hydroxide; b) from 1 to 10 phr of a phyllosilicate clay; c) at least 1 phr and less than 10 phr of melamine or a derivative thereof; and d) an alkali or alkaline-earth metal carbonate. The cable has improved reaction to fire performances especially in that no dripping occurs during burning, which renders it compliant with the requirements of the more recent international standards.

A fireproof panel light comprises a panel light housing having a wire hole for a wire to pass through and a fireproof pressure plate covering the wire hole disposed on the panel light housing; wherein, the fireproof pressure plate has a passage for receiving the wire, the passage extends from the wire hole outward to the edge of the fireproof pressure plate. The wire hole can be covered by using the fireproof pressure plate, the flame is prevented from fleeing outward from the wire hole, and the fire prevention effect at the wire hole is realized. And the extension direction of the passage on the fireproof pressure plate can further improve the fire prevention effect.
