Thermal and acoustic insulation forprotection against fire and moistureThermal insulationYtong Multipor mineral insulationboards consist of 100 % homogeneousmaterial with a heat conductivityof 0.045 W/mK.Minimum energy lossesThermal resistance R (m 2 K)/WThickness(m 2 K)/W80 mm 1,78100 mm 2,22120 mm 2,67140 mm 3,11160 mm 3,56180 mm 4,00200 mm 4,44Thermal insulation in summerPrimarily the mass of structurespointing toward the inside as well asthe percentage of window area in theexterior structures are decisive forthe thermal insulation in summer.Here, external thermal insulationcomposite systems attached to theoutside play only a subordinate role.If the insulating material in the externalthermal insulation compositesystem is calculated by itself, theheat storage capacity of Ytong Multiporis relatively high due to its density(115 kg/m³) at the same insulationthickness.Stores heatProtection against moistureYtong Multipor is treated to ensurethat it is water repellent inside andout. Short rain showers and badweather periods are no problem atall. Ytong Multipor mineral insulationboards contain only 5 % solidsand are open for vapour diffusion.Ytong Multipor does not experienceany mentionable loss in strength inthe wet state.Moreover, this mineral insulatingmaterial with its good thermal insulatingand diffusion characteristicsalso ensures a pleasant roomclimate with balanced temperatureand humidity.System open for vapour diffusionFire protectionYtong Multipor mineral insulationboards are classified as non-combustiblein construction materialclass A1 and the associated YtongMultipor light mortar ensures absolutesafety in the event of a fire.This insulating material does notdevelop any toxic gases or smokeeven at the highest temperatures.This is a true advantage for vitalrescue measures in the event of afire.non-combustibleAcoustic insulationIn spite of their high porosity of95 % by volume, Ytong Multipormineral insulation boards do nothave any negative effect for acousticinsulation. The acoustic insulationrequirements specified in DIN4109 were determined using theacoustic insulation value R W. In contrastto most external thermal insulationcomposite systems whichdecrease the value by up to 5 dB, itis maintained by Ytong Multipor.Since thermal insulation compositesystems are usually used as thermalinsulation on exterior walls, theacoustic insulating properties usuallypertain to low frequency trafficnoise.The acoustic insulating factor forthe overall construction is distinguishedby the weighted acoustic insulationvalue R W. Here, the high rigidityof Ytong Multipor ensuresgood values.Good acoustic insulation6 External thermal insulation composite system
