About 25 years ago I bought 10 "combination wood-plastic" frames that were manufactured in England. Only the top bar was wood, all the rest, plastic. The plastic foundation slid into slots on the bottom and side bars, notches on the top wooden bar snapped onto the top corner plastic joints. The frames were good and sturdy and a pleasure to use, except for one "tiny" drawback: The cell sizes imprinted on the plastic foundation were 0.1 mm smaller than the standard cell size, and getting the bees to build on them was a major headache. Most of the time, they would build a support that extended away from the foundation and they would then build their own combs between the frames. The only time they would "agree" to build on the foundation would be during very strong honey-flows.
Believe it or not, I still have a few of them in service---but with one major alteration: I drilled holes for wire support strands in the side bars and the plastic sheet of foundation has been replaced with regular wax foundation.
Would I recommend them---for those willing to try something new, most definitely. After using them for a few years on a trial basis, each keep would be able to decide for him/herself whether they suit his/her needs and expectations at the listed price.
