Best Double Wall Insulated Glass

The Best Double Wall Insulated Glass keeps your drink hot and last along time. How it works is through a vacuum technology. This vacuum prevents the transfers of thermal energy keeping heat or cold in the container. Various manufacturer of Double Wall Insulated Glass have different quality. If you buy one from a lesser manufacturer, it will usually be plagued with issues. Things like thin wall and deformation is common. For this reason, its best to find one for a larger manufacturer. This article will list some of the Best Double Wall Insulated Glass on the market.


History of Double Wall Insulation

Insulation is used in many different application. Things like the wall of your house is usually lined with insulation to regulate the temperature. It prevents it from getting either too hot or too cold. If you find it to be particularly drafty or hot, it usually due to poor design.

For things like Thermos and Cups, they use a very similar application. Some will use a foam container to trap the heat. Other will use a Styrofoam cup. This insulation prevents the heat from traveling outward and burning your hand.

For application of Cups, Tumblers and Glassware. They usually use a double wall insulation to stabilize the temperature. This technique was first used by James Dewer in 1892. Since thermal energy needs air to travel as a medium, a vacuum double wall will prevent it from escaping. Double wall insulated glass uses the same principal. They use the empty space to keep your drink hot or cold.

What to Look For Double Wall Insulated Glass

There are certain things to look for in a Double Wall Insulated glass. Things like size, shape handle are all important. Below will list a few things to help you make the best decision.

Size

Size is actually very important when it comes to temperature. Larger body of liquid are able to keep its temperature better than a smaller quantity. As such, its better to get cup sizes that are at least 8 oz. Even the best double wall insulation wouldn’t be able to keep 2 oz of liquid hot for long. While there are situation where a smaller glass would be beneficial, that temperature will be short lived. In those cases, it is better to just drink it right away.

Handle

In traditional Chinese Tea, cups have no handle. The thought is that if it is too hot to drink, it is too hot to hold. That’s not true for insulated cups. Since the thermal energy wont be transferred to the outside, you wont feel the heat burn your hand. I personally like my tea and coffee pipping hot so this benefit is actually welcomed. For more traditional cups, you can get the glass one with little handle. It looks like little mug and looks cute. But really, its not that important to have a handle on these insulated cups.

Thickness, Durability and Finish

Lesser manufacturer will often time use poor quality and thin glass. They have a tendency to shatter if you accidentally hit it. For this reason, you should stick with the bigger manufacturer. Their standards are usually better and they can take more of an abuse. Although that is not saying much. There are numerous reports across different manufacturer of the glass being broken. Usually you can reduce the risk by washing it by hand.

Borosilicate glass

If the glass is made of Borosilicate glass, thats even better. Borosilicate glass are more resistant to thermal shock preventing it from shattering. They are commonly used in Chemistry labs due to the constant heat expansion and reduction of the glass. They need something that wont constantly break. In the past, pyrex use to have these type of glass in their product. Today, I believe they use Lime Soda glass, which are prone to shattering. If you can, get one that is made of Borosilicate glass.

Finish

Since most glass is manually blown, they are prone to defects. Bigger manufacturer are better about this. They will have a tolerance and if they dont meet the standard, they will be tossed. Lesser manufacturer will try to improve their profit margin. If something is semi ok, they will still sell it to the manufacturer.
