Thirdly, acrylic insulates 20% better than glass, which reduces temperature fluctuations and saves on heating and chiller bills. If these benefits aren't enough, the seams of acrylic tanks are molecularly welded. The resin used to seal them chemically melts the two pieces of material into one solid piece for a clear polished seam that is virtually unable to leak. Another advantage of acrylic is that it has a transparency rating of 93%, which ...
