SOUNDLAG ACOUSTIC PIPE WRAP Sound Insertion Loss (A-weighted) Sound Power Levels National Acoustic Laboratory (NAL) test Report Reference ATF 750B, ATF 750F, ATF 749K 4525C Noise Reduction 4512 Noise Reduction INSTALLATION PROCEDURE (No Gluing Required) Testing Soundlag at National Acoustic Laboratory STEP 1 Measure the length and diameter of the pipe requiring lagging. STEP 2 To calculate the required width of Soundlag apply the formula below WIDTH = x (OD + (2 x T)) where: OD = outside diameter of the pipe = 3.14 T = thickness of Soundlag Example: For 100 mm pipe + Soundlag with 25mm foam. W = 3.14 x (100 + (2 x 28)) = 490 mm STEP 3 Once the width is calculated, Soundlag can easily be cut with a sharp knife or scissors. STEP 4 Wrap Soundlag around the pipe and use high quality aluminium tape (complying with AS1530.3 Four Zero Rating) to join the product together. All join must be overlapped by 50mm to ensure a good acoustic seal.
