About the Sous Vide Insulation Balls
Insulation balls
A floating cover for the water bath
A sous vide bath loses heat two ways: water evaporates from the open surface, and heat radiates off into the room. These balls float on the water and pack together into a near-continuous layer that cuts heat loss and evaporation by up to 90%.

Why it matters
Long cooks lose water
Both losses grow with the cook time. A 24-hour short rib or a 48-hour brisket can lose enough water to expose the top of the bag, while the circulator works the whole time to replace the escaping heat. Under the floating layer the water level stays stable without topping up, and the circulator cycles less often.
Under 2–3 hours
Usually a minor difference.
12 hours or longer
No water loss that leaves part of the bag dry.
Overnight and unattended
A steadier bath and less energy used by the stick.
Use
Any container, as many as it needs
The loose balls fit a sous vide container, a stockpot, a catering tub or any vessel with enough surface. Add enough for a single layer across the water, then put the stick in through the gaps, or push them aside. A stick to go with them: the LaVide LX.20.
Care
Reusable, with a mesh bag
BPA-free, food-safe polypropylene, made to be reused, and dishwasher-safe. The included mesh bag stores the set between cooks and lifts the whole layer out of the water at the end of one. Cook times by food: sous vide cooking times.

Common questions
Do I need these for short cooks?
Not really. For cooks under 2-3 hours, evaporation and heat loss are minor and most circulators handle it without issue. The balls make the most difference on cooks of 8 hours or longer.
Will the balls interfere with my immersion circulator?
No. The balls are loose and float freely, so the circulator can sit through them. Position the circulator before adding the balls, or push the balls aside to insert it.
How many balls do I need?
Enough to cover the water surface of your container. A larger container or stockpot needs more balls than a dedicated sous vide tub. Add balls until the surface is fully covered with a single layer.
Are they food safe?
Yes. The balls are made from BPA-free, food-safe polypropylene and do not come into contact with food directly — they float on the water surface above the sealed bags.
Can I use them with a lid instead?
A lid also reduces evaporation, but most sous vide container lids have a cutout for the circulator that leaves a gap. The balls cover the full surface including around the circulator, and work in containers that have no lid at all.
