This can used in frames designed for British National and WBC hives.
We only offer premium high grade wired or unwired wax for both Brood and Super frames which we use in our own hives. Wired foundations are diagonally wired for additional strength. Without wires, deep foundations have the tendency to warp. However if these are placed between fully drawn combs this reduces the risk considerably.
Unwired, super foundations are ideal for producing cut-comb or chunk honey or cut and used as starter strips for top-bar hives.
Any stored foundations that you may have can become brittle. These can be placed in a warm room for a day or two before inserting into a frame. This prevents breakage and bees will draw these out better.
