When should I reinforce the legs of the Staenis grid?

The reinforcement of the Staenis grid depends on the filler to be used.

When using load-bearing dry fillers, such as levelling or aerated concrete granules, you do not have to reinforce the legs of the Staenis grid or install extra legs.

When using non-load-bearing fillers such as glass wool or cork granules insulation, you should:

• 8 extra legs per m² to be placed in the installed Staenis grid. This increases the possible load by 100 kg per leg, resulting in a total load capacity of 1300 kg/m².
• Reinforce the top of the legs with a cement, lime mortar, ...
• Stick all feet to the surface with PU foam, so that the height adjustment remains correct after adjustment.
