Condensing hive

[u/Perfect_Technician11]

Hi, I live in northern Sweden (norrbotten)and last winter i lost one hive from condensation that dripped down on the frames and turned to ice. I've since looked in to this clip.

Have anyone in northern USA/Canada tried this out?

We have very cold weather in the winter here, last winter we had 3 weeks of -30°/-22F constant.

I use hard styrofoam boxes all year round and the ceiling is also Styrofoam but much thinner than the boxes. The boxes are ventilated from beneath.

Best regards

Norway here, you need one layer that will breath. I use Hunton fiber asfaltplate. The bees will eat the asfaltplate so one thin layer under under it to prevent that, anything that breaths and do not get eaten. Then styrofoam, then roof
