Re: Plastic-backed foundation vs. plastic frames
I do not care for the all plastic frames. I much prefer the wooden framed version with a plastic insert. I bought the plastic frames when Duraglit had the wax covering scavenged and lost its usefulness. I have found through time that the plastic frames tend to crush under the pressure of using the ear as a fulcrum for prying out the adjoining frame. You really can't repair them short of cutting the frame portion off with a tablesaw and placing into a wooden frame. They break down under UV exposure and become even more brittle. The voids in the sides of the ends allow both hive beetles and wax moths a place to hide from the bees. I find that the black plastic makes finding the correct age larvae easier too.
