The state of the issue of fire protection from landscape fires is studied and discussed. We set tasks to evaluate the recovered samples of two rolled fiberglass systems by modifying them in various ways: "fiberglass + refractory foam" and "fiberglass + aluminum foil". The first method involves applying a single layer of refractory foam Penosil Premium to the exposed surface of the samples. The second method is to modify the exposed surface by wrapping a layer of aluminum foil. The possibility of resisting an impacting landscape fire with a certain heat flux density was studied. We described the methods of conducting bench tests of a difficult-to-burn material under the influence of a constant heat flow, determine the temperature change of fiberglass from the heating time of the samples, the loss of their mass, determine the reliability of the empirically obtained data. A method for restoring a protective barrier made of fiberglass after damage by a landscape fire is proposed. At the same time, the temperature of the back side of the samples recovered using aluminum foil is reduced by half in relation to samples with refractory foam on the surface and is 173.2 °C (with the application of a single layer of foam 337.1 °C).
