When correctly installed the air leakage of the REX SDW WALL HF 1000 MW sandwich panels is approx. 2,7 m3/hour/m2 @ 50 pa. Under normal environmental conditions this is tight enough to prevent condensation or unacceptable air leakage. If necessary (i.e. coldstore applications) the airtightness can be improved by gun applied sealing the panel to panel joints using silicon mastic.
Sandwich MW panels have a weighted sound reduction of approx. 30 dB(A) (depending on thickness, example at 100 mm thickness)
