Energy-Efficient Windows

Quality windows let in the light—and that’s all they should let in! At Nu-Star Glass and Mirrors, we offer top-quality windows and expert window installation to make sure that air, drafts, dirt, and solar heat gain are not able to use your windows as a path into your home. Some of the most important energy-efficient features we’ll help you look for in your windows include:

  • Low E Glass: With the strong California sun beating down on your windows, certain rooms can get quite hot. Installing windows with Low E glass helps prevent this by blocking up to 80 percent of solar heat passage through the window.
  • Low Conductivity: Metal window frames can also heat up in direct sun and end up transferring heat into your home. By installing windows that have frames made from materials like vinyl and wood (which have low thermal conductivity) you can prevent this problem and support the energy-efficiency of your home.
  • Draft-Minimizing Design: Today’s windows are designed to be much more airtight than older windows. This helps reduce drafts so you have less conditioned air leaving the home and less outside air coming in.

Insert Windows
When original frames and trim are in good shape, you can leave them in place, saving time and disruption. Insert windows fit right into the existing frame, preserving much of the original look of the window. Available in custom sizes.


Full-Frame Windows 
If your existing window frame is rotted or deteriorated, you’ll want to choose full-frame windows for your replacement project. Although full-frame windows generally cost more than inserts, you’ll be able to maximize your visible glass using this method. Available in standard & custom sizes.

So in a nutshell, how much does custom cut glass cost typically? For common projects like single pane windows, picture frames, etc, the glass itself typically costs approximately $5-$6 per square foot. Generally speaking, the thicker the glass the higher the price.

 Can you attach shelves to a mirror?

 Attaching a glass shelf to a mirror is no different. If the mirror was already attached to the wall, it should be removed so that the glass shelf may easily be attached. If the home improvement project is a complete redesigning of the bathroom and the mirror is not on the wall, then that reduces some of the work.

 What type of glass is used for shelving?

Tempered glass is used most often for shelves and table tops. Thickness: Glass comes in thicknesses of 3/16” to ½” with ¼” and 3/8” being the most popular thicknesses.
