Langstroth Insulation Box

6   |  

Insulation is essential to hive health for any  beehive model! Since bees require a rather warm and relatively dry home, insulation is a necessity for maintaining your hive. 

This insulation (or quilt) box rests neatly atop an 8 or 10 frame Langstroth hive's inner cover. It helps to keep the inside of the hive at a constant temperature and humidity level, despite outside weather conditions. It also prevents condensation on the roof from dripping on your bees.

How It Works

The mesh bottom of the box wicks away moisture from the hive and that moisture is absorbed by the included cedar quilt material. The included cedar quilt material is 100% shredded cedar toe, with no chemicals or additives. Not only does it absorb moisture, but it provides the insulation needed to keep your hive at a stable temperature. 


  • Sugar pine insulation frame
  • Piece of moisture wicking mesh
  • 2 bags of cedar quilt material

*Please note: this item comes assembled.

Did an excellent job!

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.

Langstroth Insulation boxes nicely made, high quality

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!


Two thumbs up

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

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.

Sugar Pine is our value wood option. Beautiful, strong, takes paint or sealant well, and is more stable and lighter than more common ponderosa pine.

Western Red Cedar is our premium wood option. It is rot resistant, dimensionally stable, insulates well, and doesn't require painting or sealing.

All of our wood is sustainably harvested and FSC (Forest Stewardship Council) certified.
