The planes for slopes are specially cut polystyrene foam sheets which are most commonly used to create relief in gently sloping roof structures. Most often planes are placed in two or several layers where the bottom layer ensure technical heating parameters, but the last sheet gives the slope. However, the material can be used for creating slopes on other levelled surfaces, e.g. balconies, bathrooms, and for levelling uneven surfaces. You can create a slope starting from 1%. The standard size of plates is 1000x1000mm.
Technical thermal properties
The heat penetration of the insulation material can be from 0.031 to 0.038 W/m*K, which is a highly notable level. Furthermore, the material can be light and at the came time can withstand large loads. The sloping layer serves two functions – gives the necessary relief and serves as an additional heater. Bearing in mind the product’s properties, it can be applied and adjusted for almost all projects. E.g. a gently sloping roof made of “grey” polystyrene foam with a green area was awarded with the Annual Design Award for excellent technical solution. In comparison with analogue solutions, NEO EPS allowed reducing load on roof constructions almost 4 times.
The long-term load resistance (50 years) of polystyrene foam EPS 100 most commonly used in this solution is 27.3 kPa which is 2,700 kg/m2. Such material durability is sufficient to withstand snow, rain and wind-crated loads and stress on the roof create by movement of servicing staff. There other polystyrene foam types available. The most durable is EPS 200 which can withstand a load of 54.5 kPa which is enough for such applications as green roof and others. At the same time, the densest material weighs only 31 kg/m3; therefore, it does not create an additional load on the building’s structures.
