Thermal Insulation Guide for Travel Bottles & Mugs

If you are in the market for travel beverage containers, you may notice a lot of terminology about insulation and double wall construction that could cause a little confusion. These are just ways of explaining how well any particular tumbler, bottle or mug performs at keeping your hot drinks hot and your cold drinks cold; and you may not realized it, but this should be a factor in how you decide which product is right for you. Fortunately, we are here to explain the differences between the various levels of drink ware insulation and how they work to keep your morning cup of Joe piping hot. Here is a simple crash course on thermal insulation, so you can make an educated decision when you shop with Promotions Now.

 

Double Wall Construction

Most insulation levels consist of a double wall construction that varies from product to product but the two main purposes of this particular design remain the same. They are to eliminate condensation on the outer wall of a container when it is filled with cold liquid and to maintain the internal temperature of the container when it is filled with hot liquid. There are a few different types of double wall insulations for travel drink ware and how each one works determines both the length of time a container can keep a beverage hot or cold and how much it will cost.

Air

Air insulation is a standard double wall design that has nothing but air in between the inner and outer walls. Many acrylic travel tumblers have this level of insulation and can maintain the temperatures of cold beverages for up to 4 hours and hot beverages for up to 2 hours. They are also the least expensive of all the insulation levels.

Foam

When a layer of foam is added between the inner and outer walls, the efficacy of the insulation is increased and liquid temperatures can be retained up to 6 hours for cold beverages and up to 3 hours for those that are hot. This in turn increases the cost of the product, since the insulation is better. Many double wall, travel coffee or hot beverage mugs have this level insulation.

Vacuum Insulation

Vacuum insulation takes insulation efficiency one step further. When a mug or tumbler has double wall vacuum insulation it means that there is absolutely no air in between the inner and outer walls and the space has been vacuum sealed. This creates a less conductive barrier between the two walls and increases temperature maintenance to up to 12 hours for cold drinks and 6 hours for hot drinks.

Copper Vacuum Insulation

This is the most superior level of double wall insulation and is usually found in high end travel beverage containers. The addition of a copper plated inner wall even further increases temperature maintenance to up to 16 hours for cold liquids and 8 hours for hot liquids. This more sophisticated construction is more costly than the other levels of insulation but is also far more effective.
