Like all synthetic materials astolan is durable, corrosion-resistant and resistant to aggressive environments. Thanks to a smooth surface it does not form precipitate. Less than metal pipes weight and fast, reliable contact connection make this system very convenient for laying. PVC fittings for plumbing from Canada
In studies at the Institute of Building Physics Frauenhofer, Stuttgart, in practical situations have been shown excellent acoustic properties of ASTO (P-BA 130/1997). During tests the noise level did not exceed 12.8 dB (A) which is far below the limit, for improved insulation III level. Even the studies of acoustically unsuitable light assembly walls with a surface density of 80 kg/m2 noise pipe ASTO not exceed 25 dB (A).
Recall that according to the standards for high-level insulation for dwelling houses the noise level should not exceed 24 dB (A), for semi-detached houses and block 22 dB (A) (for normal levels of insulation for dwelling houses the noise level should not exceed 27 dB ( A), for semi-detached houses and block of 25 dB (A)).
