Pro Izo Roll CEZAR underlay is made from polyethylene. This insulation is easy and simple in handling. It is intended for flowing floors as a levelling base before laying laminates, wood-layered or wood-like floorings. Pro Izo Roll CEZAR polyethylene foam is additionally treated by polymer chains cross-linking process which improves static and dynamic load resistance. Cross-bonding of polymer chains and intermolecular structure gives high density of this insulation. Thanks to smaller spaces between chains the material has improved absorption and muffling of sounds. It is recommended to use it together with Cezar Basic Izopar – the vapour retarder film.
