The present disclosure relates to extrusion coating systems (120), extrusion coated substrates, and processes for making the same. In some aspects, extrusion coating systems (120) as described herein may include an at least partially insulated (150, 152) outlet wall, which may facilitate production of coated substrates exhibiting a very desirable surface texture and appearance. Coated substrates of the present invention may be utilized in a variety of end applications, including, but not limited to, interior and exterior construction materials for homes, buildings, and furniture. La présente invention concerne des systèmes de revêtement par extrusion (120), des substrats revêtus par extrusion et des procédés de fabrication associés. Certains aspects de l'invention concernent des systèmes de revêtement par extrusion (120) pouvant comprendre une paroi de sortie au moins partiellement isolée (150, 152) pouvant faciliter la production de substrats revêtus présentant un état de surface et un aspect très recherchés. Les substrats revêtus selon la présente invention peuvent être utilisés dans diverses applications finales comprenant, de manière non exhaustive, des matériaux de construction intérieurs et extérieurs pour des habitations, des bâtiments et des meubles.
