MULTILAYERED POLYMER MATERIAL FOR COATINGS AND METHOD FOR ITS MANUFACTURE Russian patent published in 2015 - IPC B32B1/00 E04F15/02 

FIELD: construction.

SUBSTANCE: multilayered polymer sound-, hydro- and heat-insulating material for coatings includes the lower layer in the form of multilayered polyethylene coextruded film with through holes with diameter of 6÷8 mm, which are located in one row throughout the film width with repetition of rows every 200÷250 mm, with a layer of adhesive composition 15÷20 mcm thick, which is applied to one of the sides, an intermediate layer in the form of foam polystyrene granules with diameter of 3-4 mm and an upper layer in the form of single-layered high-pressure film with a layer of adhesive composition with thickness of 10÷15 mcm, which is applied onto the side facing to the intermediate layer, with formation of a multilayered laminated structure. The invention also proposes a manufacturing method of the above material.

EFFECT: invention allows increasing degree of moisture removal from interlayer space of material due to natural and forced ventilation.
