Choosing to get replacement windows in San Marcos, CA is a big investment. You might think choosing the frame material and window style are the most complicated decisions. But choosing the right glass options on your insulated glazing unit (IGU) can be just as challenging. There are so many options to consider for the right level of safety and efficiency. So here is what you need to know about modern glazing options:
Number of Panes
Glass is a terrible insulator and it didn’t take people long to realize single pane windows were not enough protection. Today the standard for most windows is two panes of glass but homeowners can also get three or four panes. Unfortunately the cost of the extra pane isn’t always offset by equal energy savings. For that reason, most homeowners stick with the standard two panes of glass and use another glazing technology to boost efficiency.
There is more than just normal air filling up the space between the panes of glass. Air is too volatile as it expands and contracts with temperature fluctuations. More stable gasses are argon, krypton, and xenon. These are noble gasses. They have more density and do not have as much thermal expansion. Because of these properties, heat does not readily transfer through and seals last longer. Argon is the standard option, krypton offers a bit better performance at a higher price, and the most efficient and expensive gas is xenon.
Safety glass is another feature of modern windows homeowners should not overlook. The most common type of safety glass is tempered glass. It undergoes a special heating and cooling process that boost tensile strength. Instead of large, dangerous shards, this type of glass breaks into small, pebble-sized pieces. Another type of safety glass is laminated glass. This features two layers of glass sandwiched around a polyvinyl butyral (PVB) interlayer. So even if the glass does break it still remains largely intact inside the frame.
Special Tints and Coatings
Tints have to do with heat transfer and visible light. The most common tints are blue, green, grey and bronze. As with a car window, these tints help improve privacy, provide more insulated from radiant heat, and put a damper on glare.
Etched glass is more than just aesthetics. It can improve security by obscuring the view inside the home. This is great if homeowners are looking for plenty of natural light while still maintaining privacy. Best of all there are countless designs and options to suit individual preferences and home design.
Low-emissivity, or Low-E, glass features the application of an ultra-thin metallic layer to certain surfaces of the glass. They are not visible and do not block visible light, but readily reflect radiant heat either back out or back into the home.
