Today there are so many manufacturers of Window Replacement; it can be difficult to choose a quality product. Of course every Window Replacement or window salesperson claims to have the best product. There are several design elements and options to look for when choosing your Window Replacement Mill Creek professional. Some of the elements of Window Replacement Mill Creek are listed below:

  • IG Units - is the number of panes of insulated glass - Window Replacement Mill Creek
  • Low-E - is "low emittance" coatings, which minimize thermal radiation (damaging rays) - Window Replacement Mill Creek
  • Low Conductive Gas Filled - Argon or Krypton - Window Replacement Mill Creek
  • U-Factor- heat loss rating - Window Replacement Mill Creek
  • SHGC Factor - amount of solar radiation (heat) admitted through a window - Window Replacement Mill Creek
  • VT - Visible Light Transmission - Window Replacement Mill Creek

The following information will take some of the "mystery" out of window terms. Window Replacement Mill Creek

IG Units- What is "IG" unit? Window Replacement Mill Creek

Today, quality windows are built around what's called an insulated glass (IG) unit. An insulated glass unit starts out as two or three individual panes of glass that are chemically bonded by a sealant to spacer bars. When comparing vinyl replacement windows, always ask about the IG unit. Because not all windows or glass are alike, you should require the highest quality and performance standards.

Low-E - is it for me? Window Replacement Mill Creek

Low-emittance (Low-E) coatings are thin, metal or metallic oxide layers deposited on a window surface primarily to reduce the U-factor by suppressing the heat flow through the glazed window unit. Coating the inner glass surface with a low-emittance material between the glass layers, blocks a significant amount of this radiant heat transfer, which lowers the heat flow through the window. Low-E coatings are transparent to visible light. Different types of Low-E coatings have been designed to allow for high solar gain, moderate solar gain, or low solar gain. We usually recommend Low-E for any regions in your home that receive a lot of direct sunlight. One thing to remember is the windows have a slightly tinted appearance. Window Replacement Mill Creek

Low Conductive Gas Filled Units Window Replacement Mill Creek

An improvement that has been made to the insulating performance by the use of argon or krypton gas between the panes of glass. Normally, the space is filled with air or dry nitrogen prior to sealing the window panes together. In a sealed glass insulated window unit, air currents between the two panes of glazing carry heat to the top of the unit and settle into cold pools at the bottom. Filling the space with a less conductive gas minimizes this and the overall transfer of heat between the inside and outside is reduced. Window Replacement Mill Creek

Argon is inexpensive, nontoxic, non-reactive, clear, and odorless. The optimal spacing for an argon- filled unit is the same as for air, about 1/2 -1 inch. Window Replacement Mill Creek

Krypton has better thermal performance, but is more expensive to produce. Krypton is particularly useful when the space between glazings must be thinner than normally desired, for example, 1/4-inch. A mixture of krypton and argon gases is also used as a compromise between thermal performance and cost. Window Replacement Mill Creek

The use of conductive gas filled units has significant insulating benefits but comes at higher initial cost. Window Replacement Mill Creek

U-Factor - What exactly is it? Window Replacement Mill Creek

The rate of heat loss is indicated in terms of the U-factor (U-value) of a window assembly. The lower the U-value, the greater a window's resistance to heat flow and the better its insulating value. Winter nighttime U-values are calculated using an outdoor air temperature of 0 degrees F and outdoor air velocity of 15 mph, indoor air temperature of 70 degrees F, and air velocity of 0 mph. This is similar to the R-value that you think of when choosing insulation except a low U-factor is better, unlike R- value which the larger the number the better. Window Replacement Mill Creek

It is calculated as 1 divided by the R-value = U-factor. If you used this calculation R-13 insulation would have a U-factor of 0.077. Window Replacement Mill Creek

To convert U-factor to R-value you take 1 divide by the U-factor. If you used this calculation for the average aluminum framed window with a U-factor of 1.125, your R-value would be 0.89 Window Replacement Mill Creek

Good replacement windows depending upon the glazing options and low conductive gas fills range between 0.5 and .1 for the U-factor. Window Replacement Mill Creek

SHGC Factor - What is it? Window Replacement Mill Creek

Solar Heat Gain indicates the total amount of solar energy that passes through glass relative to a 1/8" (3mm) thick clear glass under the same design conditions. It includes both solar energy transmitted directly plus any absorbed solar energy subsequently re-radiated into the room. Lower values indicate better performance in reducing summer heat gain and, in turn, air conditioning loads. Your average single paned wood framed window has a SHGC of 0.98 whereas a quality replacement window will have ratings from 0.91 - 0.39 depending upon glazing options. Window Replacement Mill Creek

VT- Visible Light Transmission Window Replacement Mill Creek

The visible transmittance (VT) is an optical property that indicates the amount of visible light transmitted. The VT is a whole window rating and includes the impact of the frame which does not transmit any visible light. While VT theoretically varies between 0 and 1, most values are between 0.3 and 0.8. The higher the VT, the more light is transmitted. A high VT is desirable to maximize daylight. Window Replacement Mill Creek

I hope this article helped demystify the terms used when you are contemplating your new vinyl replacement window purchase. Purchasing a quality window is only a part of the equation. The installation is the largest factor of how your windows will perform. Take great care installing and insulating around your existing openings and windows to assure you receive the maximum performance possible from your new windows. Window Replacement Mill Creek
