What’s the Difference? Double Wall Insulated vs Single Wall Water Bottle
How you choose a water bottle, a stainless steel water bottle, you only want to have a stainless steel bottle for drinking, no any requirement except for food contact safety basic reqirement, or you want the bottle can keep your water liquid hot or cold hours in hot Summer or Cold Winter days, then we have breakdown of the major difference between double wall insulated bottle VS. single wall bottle.
Single wall bottle & double wall insulated bottle both use Stainless steel, and you need to know what stainless steel material the bottle is?
Stainless steel 18-8 (SUS304); Stainless steel 18-1(SUS201); Stainless steel (SUS316 Medical grade)
These different materials has different quality on the FOOD CONTACT & Anti-Rust corrosion performance.
2. Keep it hot, keep it cold
The most obvious difference between double wall insulated bottle and single wall bottles is how long they hold their water liquid temperatures inside the bottle vessle in the hot Summer Days or cold Winter Days. The insulated bottles can keep cold liquids cold for up to 24 hours and hot liquids hot for up to 12 hours in technically. We can use the double wall insulated bottle for warm coffee and tea throughout the day, or for keeping water (or beer) icy cold after a long day outside.
But you only want to have the water bottle to drink water in a short time, the single wall bottle is good enough and it is much cheap and light for easy carrying on the go.
3. No Sweat
Don’t not want the water bottles sweat? Well, when air comes in contact with a non-insulated bottle with cold water it begins to cool down. If it cools enough, water vapor in the air is condensed and turns to liquid that beads up on the outside of the bottle. With a the double wall vacuum insulated bottle, this doesn’t happen. The outside of the bottle just doesn’t get cold enough when it with cold water inside the bottle, keeping water rings off your table or contents of your bag from getting wet with bottle sweat.
