Energy ratings are an important consideration when choosing windows and doors for your home. They can help you determine the energy efficiency of a product and its potential to save you money on heating and cooling costs. However, energy ratings can be confusing and difficult to understand. In this article, we’ll provide a guide to understanding energy ratings for windows and doors.

What are energy ratings?

Energy ratings are a measure of the energy efficiency of a product. They are designed to help consumers make informed decisions about the energy performance of windows and doors. Energy ratings are based on a scale of A to G, with A being the most energy efficient and G being the least energy efficient.

How are energy ratings calculated?

Energy ratings are calculated using a number of factors, including the thermal performance of the product, the amount of air leakage, and the solar gain. The thermal performance of a product is determined by its U-value, which measures how much heat is lost through the product. The lower the U-value, the more energy efficient the product. The amount of air leakage is measured by the product’s air permeability rating. The lower the air permeability rating, the less air will leak through the product. The solar gain is a measure of how much heat is gained from the sun through the product.

What do the energy ratings mean?

Windows and doors with an A rating are the most energy efficient, while those with a G rating are the least energy efficient. A-rated products are designed to provide the highest level of thermal performance, with low U-values and air permeability ratings. They are also designed to minimize solar gain, which can help keep your home cool in the summer. G-rated products have the lowest level of thermal performance and the highest level of air leakage and solar gain.

Why are energy ratings important?

Energy ratings are important for several reasons. First, they can help you save money on heating and cooling costs by choosing products that are more energy efficient. Second, they can help reduce your carbon footprint by reducing the amount of energy you use to heat and cool your home. Finally, energy ratings can help you choose products that comply with building regulations and standards.
