How does vacuum insulation work in a stainless steel bottle for hot water?

The science behind our stainless steel bottle for hot water performance:

• Double Walls: Two layers of stainless steel
• Vacuum Space: Air removed between walls of stainless steel bottle for hot water
• Heat Transfer Blocked: Heat needs material to travel through—vacuum has none
• Copper Coating: Reflects radiant heat back into beverage
• Result: Only 5-10°C loss over 6 hours in stainless steel bottle for hot water

This technology makes our stainless steel bottle for hot water 10x more effective than single-wall bottles.
