Stick with what please? Here's a photo of my set up - OMF National/Brood Box/Eke/Fondant/Polycarbonate Crown Board/Ply over Feeder HoleDepends on what your intention is in the long term, as well as how deep your roof is, even with a four inch roof there's enough room to have 50mm deep kingspan permanently fitted - just cut it so it fits snuggly inside the room (rip out the narrow batten lining the roof if you feel confident enough) then stick it in place. if you also then want a piece of 50mm Kingspan to surround a tub of fondant, with a 4" roof, cut it to fit an eke, with an 8" roof just cut it to the size of the crown board (no real need for an eke).
It's actually a trade name.Whatever you have handy - silicone sealant works, nomorenails, or something like Gripfix available at your builder's merchants (commonly refered to as stickslikesh!t)
It is now - didn't used to be when I first used it - and it wasn't an Evo-stik product eitherIt's actually a trade name.
They don't NEED any. Some people choose to add some further insulation at the top of the hive (not the sides). This is done in various ways, depending on the hive setup (see above for examples).Am I correct in assuming that polly hives do not need any insulation.
Some poly hives have relatively thin roofs compared to the wall thickness . I always have insulation above the crown board... I've noticed that the heat at the crown board is greater if there is a slab of insulation above the crownboard under the roof than it is with the roof in its own. I put a super between the roof and the crownboard and put my PIR in that .... works for me but I'm not a proper beekeeper...Am I correct in assuming that polly hives do not need any insulation.
