Insulated Glass

"Heat loss costs money and energy, but it can be prevented. Insulating glass is the single most effective product that you can provide for your home to save energy and cut heating and cooling costs" (CRL).

Insulated Glass is manufactured of two pieces of glass separated by a spacer. The spacer contains water and chemical absorbent. The absorbent prevents the unit from building up moisture. Since the absorbent can absorb only so much moisture, the unit is hermetically sealed. Once the seal is broken, the unit starts fogging up and is no longer usable. The problem cannot be fixed by resealing the unit, because the moisture absorbing material inside is up to its capacity.

Safety Glass

The two most common types of safety glass are tempered glass and laminated glass. They are usually used in high traffic areas, such as door entrances.

Laminated glass is manufactured from two pieces of glass held together by flexible clear plastic. It can be cut to size just like regular glass. If the glass is broken, the plastic keeps it together to prevent sharp edges, which may cause injuries. Laminated glass prevents objects from passing through it even after it has been damaged. That is why it is used on car windshields and storefronts to prevent intruders.

Tempered glass is manufactured by exposing it to high temperatures. This process makes it up to five times stronger than regular glass and brings up its heat tolerance. When broken it shatters into many tiny pieces. That prevents long sharp edges, which may lead to personal injuries. Its safety features are used in car windows (except windshields), entrances, tabletops, and others places where safety is an issue. Tempered glass is also used in fireplaces, ovens, and other high heat places.

Unlike regular and laminated glass, tempered glass shatters when cut. That is why all tempered glass is always custom made. Preparing regular glass to size and then tempering it is the process to manufacture tempered glass.

Low-E Glass

Just like insulated glass, Low-E glass helps energy conservation. It reflects most of the heat energy back where it belongs. It works in the winter to keep heating costs down, as well as in the summer to keep cooling costs down.

In the winter we want to keep the inside warmer. The low-e glass helps to do that by reflecting the heat back inside. In the summer we want to keep the inside cooler. The low-e glass then reflects the heat coming from the sun back out, helping with the cooling bill.
