Hive insulation

2 insulation threads.

I'm intrigued by what looks like sponges in the photo. Are they soaked in oxalic acid or similar?

No not sponges.
They are small blocks of wood.
I put these either side of the feeder hole in the crown board (perspex) so the bees don't get squashed.

At the risk of sounding (being) dumb- what is PIR?

Polyisocyanurate (can you guess why people call it PIR? ). Sold in the UK and Europe as a rigid foam board faced with aluminium foil, anywhere between 12mm (½") and 150mm+ (6") thick, for insulating buildings, typically used between the leaves of a hollow wall and between rafters/joists.

Ah, thanks. I wondered if you were trying a varroa treatment like Randy Oliver. Looks like you've put a lot of thought and effort into your set up.

Ha ha. It's vinyl car wrap.
I make these out of 30mm pir.
Back to back.
30mm pvc channel to top off the edges and 30mm pvc angle for the frames to sit on.
All stuck with ob1.
Phill.

Where did you get the PVC channel, out of interest?
