Energy Efficiency

The selection of glass in today’s home must consider a number of different questions. Some of which include aesthetics, performance and comfort.

The location and type of home must also be part of the equation in determining what type of glass is best suited for your home.

In the selection process there are compromises that may be necessary. For example, the glass product that provides high visibility may not always provide the best solar control. Paramount can offer homeowners a wide selection of Low E and tinted products and provide you with the information you require to make the right decision.

What is Low E?

Low E is a coating that’s applied (usually on the inside of the outside panel) on the glass to reduce energy costs both in the winter heating season and summer cooling months.

Paramount provides a number of Low E products. The three most common are Low E 272, 240 and 366. They are primarily used with argon gas and a warm space edger to provide a very energy efficient insulated glass unit.

Types of Low E

Low E 272

272 is the Low E used predominantly in Paramount insulated glass units because it offers year-round performance and comfort. In winter, it reflects heat back into the room. In summer, it rejects the sun’s heat and damaging UV rays.

Low E 240

Where glare is a problem, turn to Low E 240. It controls glare but also blocks oppressive solar heat gain and maintains cool indoor glass temperatures. This is particularly effective on elevations of your home with little shade or overhang.

Low E 366

Low E 366 delivers the perfect balance of solar control and high visibility with no room darkening tints and virtually no exterior reflectance. It provides excellent year-round comfort and reduced energy consumption for any location.

 Glazing options

Double glazed; 1 Low E, 1 argon gas, 1 warm edge spacer.
