Windows And Doors: Understanding Energy Performance

Homeowners who buy windows and doors are most concerned about productivity. After all, a window or door that doesn’t work on one level means a power outage, so you can literally send money out the window. 

Luckily homeowners can buy all types of Energy Star windows. Companies that make windows and doors are not required to use this rating system, but many do. Before you buy a new window or door, find out what these ratings mean. You can navigate to this website for the replacement for the windows and doors in Ajax.

Understand the U-factor: The U factor is the rate at which a window, skylight, or door conducts non-solar heat flow. Just like the Golf, lower numbers are better – lower numbers mean higher energy efficiency. When comparing the U-factor, consider whether the entire window or door or just the glass is covered. 

Understanding solar heat gain: Another estimate to consider is solar heat gain. It measures the solar radiation emitted into the home. The lower the solar heat gain, the less heat is released, which is ideal for warm climates most of the year. 

On the other hand, the high intensity of the sun’s heat helps keep the house warm in winter and cold climates. There is no perfect solar heat gain coefficient for all climatic conditions, so you should choose the right coefficient based on where you live and the orientation of the walls.
