FIELD: construction.
SUBSTANCE: multilayer laminated material (10), containing the first layer (11) made from a mixture of polymers containing polyethylene terephthalate and material chosen from a low-density polyethylene, medium density polyethylene, high density polyethylene or polypropylene, the second layer (12), made from a specified mixture of polymers, and the third layer (13) located between the first and second layers (11, 12). The specified third layer (13) is made from a specified mixture of polymers with the addition of glass fibres and the polymer blend contains between 6 to 14 wt % of one of a low-density polyethylene, a medium density polyethylene, a high-density polyethylene or polypropylene, and the rest is a polyethylene terephthalate. A heat-insulating panel is also described.
EFFECT: material for use in a chemically aggressive environment, cheaper than fiberglass, is proposed.
