Extruded Polystyrene (XPS) is a durable, water-resistant insulator with high mechanical performance and does not rot. Placed on the waterproofing (inverted roof), in addition to insulating, it protects the waterproof sheet and improves its durability.
Extruded polystyrene in its forming process produces a closed bubble structure, which makes it the only thermal insulator capable of getting wet without losing its properties.
Extruded polystyrene acts as thermal insulation by reducing the thermal oscillation of day and night, which leads to a reduction in fatigue to which materials are subjected due to expansions and contractions, especially waterproofing. In addition, the non-adhesion and dry placement of the insulation layers on the waterproof film facilitates access to it for repair and maintenance work.
They can be finished as walkable or non-passable roofs, either by pedestrians or by road traffic, or as landscaped roofs. Naturally, when the insulation is directly exposed to external aggressions (thermal oscillation, rain, weight, etc,...) it must be carefully selected.
