Roger Delon's Stable-Climate Hive (La Ruche Climatstable)
Roger Delon (1919-2007) was a commercial beekeeper in the Vosges/Jura region of France/Switzerland and is understood to have kept at least 600 hives in apiaries over a 120 km wide range. He was committed to the Warré box size, as his was only 5 mm higher, and to the principles of keeping in the brood nest warmth by adding new boxes underneath at the critical time. However, his hive and its management differs in several ways from Warré's as set out in the following table:
The thick walls, the insulated crownboard and the sloping floor with its full-width entrance to deal with any condensation suggest that Delon's variant of the People's Hive hive would be better suited to cold climates than the latter. His use of frames that do not prevent the nest from being hermetically sealed at the top, or from being bridged in places to the sides of the box, yet can be removed easily because of the single length of stainless steel reinforcings rod embedded in the comb at the sides and bottom, may have special value in countries where state law requires combs to be easily removable for inspection, e.g. USA and Canada.
The following composite photo is of an original Delon frame. It seems likely to have been a Mk.I version because the wire is not stainless steel and therefore has rusted. A detail shows the method of insertion of the wire into the top-bar. The hinge formed allows the metal 'U' to swing into a vertical plane. The bees would eventually secure the wire with propolis and comb. The central slots, which were used for securing foundation, appear to have been cut from the underside with two incisions with a circular saw, because at the centre they do not align properly (see detail) and there is evidence of the work of the saw. (Thanks to Jean-François Dardenne for providing this sample which he received from Roger Delon in 1996.)

A Dadant 'growing down' or migrating into a Warré fitted with Delon frames and foundation. This process was started on 10 April 2008. Two weeks later there were mature queen cells in the Dadant and the Warré. The unit was used to make four colonies: 2 Dadant, 2 Warré (photo: Benoît Dupret).

Slobodan Z. Jankovic (Serbia) has further developed the Delon version of the Warré into what he calls the 'Alpine Hive': http://pcela.rs/alpine_hive_1.htm. It has either Delon frames or wooden ones.
A variant of Delon's hive is also in use in Russia:
