Opacity and Strength of Clear Polycarbonate Multiwall, how clear and strong is it?
Note: Multi-wall clear polycarbonate is not 100% optically clear. See Multi Wall Polycarbonate
Photo shows glass on left, polycarb on right. This is clarity you can expect from multi-wall polycarb. 8mm sheet has ribs (channels) every 3/8″. Since ribs are spaced farther apart (about 3/4″) on the 16mm, these sheets offer a extra clarity. Do not expect to see images clearly. Polycarb diffuses the sun’s rays, which is excellent for plant growth, costs less than glass and is simple to install.
If building an attached sunroom and must have total clarity on walls use windows or doors.
