Are most glider canopies made of approximately the same thickness

All the ones I've looked seem to be about 0.60". Typical acrylic's
cutoff is steep and deep (1% transmission below the cutoff), so even
twice the thickness makes little difference. The acrylics designed to
pass UV (at least from the Cyro company) have a more gradual "tail".
