Impregnated Frames are used in an Apiary (or Frame Housing in an Alveary). As with other Forestry Frames, they increase the production of bees by 10%. They are more durable than Untreated Frames, and less durable than Proven Frames (which cannot be crafted).
Note that they are crafted from Impregnated Sticks rather than Sticks.
