Window Energy Ratings.
Importance of Window Energy Ratings.
1-They enable users of pieces of equipment to compare the different energy efficiencies of window products.
2-Help homeowners when selecting the suitable types of windows for their homes.
The type of windows in your home play a significant role in security issues and affect the warmth of your home. Many human diseases are caused by cold and flu.
Homeowners should install Energy-efficient windows correctly to reduce the amount of heat loss in their living areas. With better heat control measures, windows play a significant role in reducing the average energy bills in homes. They regulate the levels of heat and lower the cost of electricity used in heaters.
Windows with low energy ratings perform poorly and are a cause of heat loss in homes. It then results in high electric bills.
Buyers should carefully study the Window Rating Energy Label to get a review of how the window product works.
The window rating labels have a similar design as the labels used in washing machines and refrigerators. They all use a rainbow design for double glazing Hampshire.
Types of energy rating processes for windows:
1-Schemes conducted by the British Fenestration Rating Council found on the top left of a window product.
2-Those operated by the British Standards Institute found above the centre of the window product.
3-Rating schemes used by CERTASS and located at the top left of the window product.
All the different strategies work in a uniform procedure.
Window products are given letter ratings with respect to the performance of the window, glass type, frame design, frame material and other parts of the window product. A window that is rated A+ is more efficient than a window rated C.
The formula used to calculate the letter rating considers the window product’s solar gain(The amount of heat that passes through the window from the sun), air leakage, and overall thermal efficiency.
Energy-savings and Energy-efficient windows.
The level of efficiency a window product offers is what is indicated in the window energy rating label.
Factors affecting the amount of energy saved after installing a window product:
1-Effectiveness and efficiency of the heating system.
2- The posture of the building and its orientation.
3-Other insulation systems installed.
4-The window’s location.
Window Energy Ratings FAQ.
What is the suitable Window Energy Rating for my home windows?
You can compare your potential savings by choosing to use Window Energy Ratings. The ratings are accurate and simulated by computer-aided designs, and by so doing, windows with high energy ratings are bound to offer more on potential saving.
Different window products have different energy ratings. The buyer has to consider the energy efficiency levels of the window product and other factors such as:
1-The required levels of planning and restrictions involved.
2-Material preferences.
3-Design needs.
4-The budget available.
Since 2009, KJM has been offering class A, C and E of window products. We now only provide type A and class C rated windows with the current regulations on window products. The difference between the two classes is almost negligible that we end up advising our clients to choose frames with an A rating.
Window Energy Rating(WER)
The window energy rating is the overall procedure and method used to calculate the energy performance of various window products. The following criteria is used to determine the average energy level rating of a window:
1-Solar Gain.
2-Air Leakage.
3-Type of glass used to make the window panes.
4-Type of frame material used to make the window(timber, aluminum, or PVC)
