Insulating the Cathedral Hive in winter

Since The Cathedral Hive is a much bigger volume hive you can wait until November or December to insulate the hive if your hive is over 1/2 full of combs. Do watch for extreme fluctuations in temperatures. Here is Colorado we can get extreme drops heading towards winter, 70 degrees during the day and in the teens by night. This is extra tough on the bees so be ready to insulate.

The Cathedral Hive Vented Slots filled with propolis
The bees will most likely have sealed the vent slots in the top bars with propolis. The bees know best how to regulate their hive so
do not cover these slots for them as it may overheat this large volume hive. The bees still need some air flow in the hive.

 

Getting some insulation at the store is easy as there are just a few pieces of insulation to purchase.


Insulating the top, underneath your ventilate roof

 The Cathedral Hive cut reflective bubble insulation

First cover the vent holes on the Upper Section. Reflective bubble insulation is perfect for this and can be purchased at a home improvement store.

The Cathedral Hive cover window reflective bubble insulation

This reflective bubble insulation can also be used to use in between the window and window cover of the hive.


The Cathedral Hive insulating with blue or pink foam

Use 1-2" thick blue or pink foam insulation to go under the Ventilated Roof of your hive

 

The Cathedral Hive insulating with rigid foam board

Use rigid foam insulation board insulation to slide between the exterior panels and the Upper Section of the hive. This will really help insulate the hive
since the bees are hanging on the combs in this Upper Section of the hive.

 



Once the temperatures really drop some optional insulation

In this image you can see that the snow is melting around the exit of the ventilated roof. This is a great sign that the bees are warming
the hive and there is still air flow.

Some further insulating can be done once the temperatures are much colder during the day and night.
Here in Colorado that is normally in January and February but just watch your local temperatures to
b e a consistently below 30F

In colder temperatures you can add board insulation in the front and back slots, remember to watch this to not overheat the bees
on any days when the temperatures start to warm up, even in the middle of winter

In colder temperatures you can add reflective bubble insulation in the gap between the ventilated roof and hive.
