Window Replacement Reviews and Ratings
And in addition, wood clad and fiberglass window frames rated the highest. (These replacement windows also carry the greatest price tags.) These window frame materials are better at keeping out the rain, wind and elements. Each window was put through a week of extreme temperatures to see how a window expanded, contracted and flexed with temperature and condition changes. Each window was then tested for water and air leakage. Windows that exhibited little if any change in performance from the beginning to complete were ranked highest.
Vinyl is more affordable and convenient
Vinyl window replacement account fully for nearly 50% of the marketplace since they are reasonably priced and maintenance-free. However, vinyl windows will let some air seep through, especially in colder climates. Furthermore, vinyl is less attractive than wood clad and is unable to be stained or painted to match or compliment a home’s exterior color.
Replacement Window Ratings
When comparing exactly the same type and type of window from different manufactures as well as different lines from exactly the same manufacturer, you have probably noticed one thing: no two windows are exactly the same. Don’t panic! There’s no need to resort to anything as drastic as defenestration – or jumping out of a window. In order to ensure your replacement windows will provide you with great home comfort and energy cost savings, the National Fenestration Rating Council or NFRC and Energy Star provide a good rating system for evaluating window quality and energy efficiency.
It may be difficult to compare claims produced by different window manufacturers, for the reason that they often use different window measures and rating terms to market their products. As an example, some may use center-of-glass R-value and shading coefficient, while others use whole-window U-factor and solar heat gain coefficient. Fortunately there’s now one place to look that’s standardized ratings for windows – NFRC. The National Fenestration Rating Council (NFRC) is just a nonprofit coalition of manufacturers and window experts that’s set standards for testing and labeling windows.
The National Fenestration Replacement Council
The NFRC has developed a reasonably comprehensive window performance/ energy star rating where they provide uniform and definitive benchmarks by which all window companies must now measure a window’s energy performance. You can easily compare windows from different manufactures or different lines from exactly the same producer because the data is handily and precisely presented in an clear to see summary. However, you should be forewarned that windows are evaluated and rated when they’re new and therefore long-term resilience is not taken into account. Furthermore, the Council doesn’t perform studies on already installed windows or their history.
The NFRC Window Replacement Rating System
The important thing element to the National Fenestration Replacement Council rating system is just a window’s U-factor. The NFRC gives each window a U-factor rating. The first number after what U-factor could be the rating that’s appropriate for residential purposes. It is likely to be marked AA or Residential. The U-factor marked BB or Non-Residential is for commercial window applications. The U-factor on the NFRC label always describes the complete window. To ensure you are comparing apples to apples, look for the NFRC ratings even if you have no label in your window replacement. Also, make sure you use the same size windows for comparison, as the ratio of glass to framing affects the result.
U-value measures just how much heat actually flows through a material. NFRC has U-value measurements of different replacement window systems. In other words, the reduced the U-value, the more a window’s resistance to heat flow and the higher its insulating value. U-factor rating ranges from 0.10 to 1.20. The reduced the U-value, the decrease your heating costs. You may also want to compare air leakage. This rating corresponds to the ratio between the amount of cubic feet of air that passes through a window divided by the square feet of window area. The reduced the AL is, small the leakage.
