Many homeowners think curb appeal is along the lines of landscaping, siding and roofing; however, installation of replacement windows in Johnston offers you the opportunity to upgrade your home’s resale value and style. Considering that about 40% of the central heating is lost through doors and windows, having quality window replacements represents substantial savings on your utility bills.

One more reason you should consider for replacing your window is that such a change will deliver great savings in convenience and maintenance costs. In order to purchase the best replacement windows for your home, you have to take into consideration the NFRC rating.

The Window’s NFRC Rating

The National Fenestration Rating Council (NFRC) has a rating system that considers the following factors:

1. How the new replacement windows will save you money on utility bills
2. Types of window openings
3. Window frames
4. Window glazing

However, NFRC does not take into account the durability of windows because it only rates new windows. When comparing replacement windows, it is vital that you check for the NFRC label clearly indicating the U-factor. U-factor is the inverse of R-factor used for attic insulation. Therefore, U-factor of 0.5 is about the same as an R-factor of 2. Lower U-factor indicates better performance.

For residential purposes, “AA” or “Residential” indicates the U-factor. “BB” or “Non-residential” U-factor marking indicates that the window is for commercial purposes.

A Guide to Purchasing NFRC Windows

One of the first things you need to consider is the price of your windows. Remember that a sizable portion of the cost goes into the installation, and it makes sense to leverage the costs by purchasing better replacement windows. Here are some guidelines on NFRC rating windows.

Purchase double-pane windows with low U-factor:

1. When you expect to move out soon
2. You have inexpensive oil or gas heating
3. When energy prices are expected to drop or remain stable
4. When you expect a higher income in about 15 years

Purchase triple-pane windows with very low U-factor if:

1. You will live in your home for more than 10 years
2. You have expensive electric heat
3. Expect the energy prices to rise
4. When you predict lower income in 15 years

Since NFRC ratings do not address the durability of the replacement windows in Johnston, a reputable installer can offer you advice on the best choice on the market. Click here for info on expert installers.
