I purchased two insulation boxes to mitigate the moisture build up during the VERY wet winter we just experienced here in Northern California. The insulation boxes did an excellent job of absorbing the moisture that would otherwise have collected under the the inner cover, possibly dripping on the bees, as well as preventing patches of mold that has sometimes developed on the underside of the telescoping covers.
Well made, fit perfectly, and the included cedar shavings were plentiful. This is my first time using insulation boxes with absorbent material, so I am looking forward to seeing how they perform. I purchased two 10-frame, and one 8-frame box. Hoping my bees survive this crazy winter!
Assembled and ready to install. Good craftsmanship with quality materials Can't give it a 5 star yet, will reevaluate in the spring.
It worked out great...
These are relatively easy to construct but a real time saver purchasing the pre-cut WRC kits along with the cedar shavings; also, purchasing WRC lumber locally is a hassle.
