PAVERWOOD IL 25

IL 25 is an Acoustic block for load-bearing walls.‎ Technical characteristics: Concrete thickness: 18 Litres of concrete per wall: 148 Weight of block in Kg.‎ +/- 10%: 10.‎8 Weight of plastered wall Kg.‎: 520 Wall resistance "R" MqK/W: 0.‎61 Transmittance "U" of wall*: 1.‎64 Yie: 0.‎036 Cooling time in hours: 14.‎326 Surface mass: 457 * Thermal transmittance calculated using the two-dimensional method in accordance with UNI-TS 13788, UNI 10355 and UNI 10351 The sound insulation must be tested on site as prescribed by the regulations.‎ From 42db to 46db is the result that was reported by the companies that did the acoustic tests for external walls and above 50db for partition walls.‎ The quality of the product starts with the raw material.‎ The company produces the blocks using only the chips from PEFC certified spruce, only raw material that guarantees high quality standards; sawdust and dust are removed with special vibrating screens.‎ The petrified wood chips are mixed with “Portland” cement, and then printed and dried naturally, so as to obtain a fully ecological block that does not burn, does not rot, is highly breathable and has high thermal and acoustic insulation.‎ For purely acoustic blocks, the density is further increased.‎
