<We have used Reflectix in cold and hot weather > I can see using it INSIDE the hive, say over a brood nest in cool weather. In our climate, if you put it outside the hive on top of the cover, you might help hold in some of the hive heat, but you'd likely reflect off the sun that we want to warm the boxes - when and if we see the sun. Reason we use BLACK roofing felt - to absorb radiant heat. I do use Reflectix on the inside of the garage door on my shop. The shop is insulated, the old garage door wasn't. Shop gets some warmth from the house, but it is not heated. I use an electric infra-red heater when I'm working in the shop. I just stapled the foil on the inside of the door (it bends, so does not interfer, and I can run it right over the hinge areas - stopping air infiltration through the spaces between the horizontal door panels. If its windy outside, I aim the heater at the door. The Reflectix works great for bouncing the heat back into the shop. Finally, I had to haul a trailer load of bees to NE in very hot, sunny weather. I pulled Reflectix over the whole load - just on the top and on the sides where the sun would hit. Helped keep them cool - I had temp probes in the hives and a misting system that I could activate from the truck cab. However, I had always thought that the comments in organic gardening mags about putting foil on the ground btw the rows would cause insects to fly upside down was a myth. Until I saw bees fly home to the hives on the trailer. Some of those flying over the foil did a back flip and spun in circles on top of the Reflectix.
