FIELD: construction.
SUBSTANCE: invention relates to the sealing profile for doors and windows made of the mixture of materials including about %: ethylene-propylene-diene rubber 10-50, propylene copolymer with ethylene 8-50, the filler 50-70, paraffin oil 0-20, accelerator - sulfur donor 0.1-5, sulfur 0.5-5, zinc oxide 0.5-3. The method of producing the window or door structural element is also described which uses at least two sealing profiles of the mixture of materials containing ethylene-propylene-diene rubber and propylene copolymer with ethylene, wherein the mixture of materials is blended, shaped, and then cross-linked under the influence of temperature followed by retracting of the sealing profiles into the corresponding structural elements and by welding of the structural elements and the sealing profiles to each other in one pass.
EFFECT: invention provides weldability of the sealing profile.
