Understanding Some Features When Choosing Stacker Doors for Your Home
Stacker doors, or sliding glass doors such as you would install in a patio or outdoor area, can be a great addition to any home, especially if you want to enjoy added sunlight while indoors. Stacker doors allow you to easily access your outdoor space and create a transition from the inside area to the outdoors. If you're ready to choose stacker doors for your home, you want to ensure you understand all their features and ratings. This will mean getting the best doors that help insulate your home and keep it protected. Note the following.
1. What is the "U" value of windows and doors?
You may see stacker doors with a "U" value rating, and this refers to the amount of heat that is lost from inside the home. The U value rating will take into account the glass and the frame of the door so that you know how energy-efficient the entire piece is and how much heat you might lose during colder months. Low U value ratings mean less heat is lost during colder days, so you might want to invest in a door with the lowest U value rating that you can afford so your home is always well insulated.
2. What does SHGC stand for?
This rating is something of the opposite of the U value of doors and windows; it measures the amount of solar heat that is allowed to pass through a door, including the glass and frame. Lower SHGC ratings mean less solar energy is allowed to go through the door and the frame, so the entire piece is better shaded. If the stacker door you choose will be in direct sunlight, you want the lowest SHGC you can find.
3. What does BAL stand for?
BAL stands for bushfire attack level, and this refers to how well a door holds up under a bushfire from the outside. This rating is often used in Australia and other parts of the world where bushfires are more prevalent. Be sure to note the level of protection against a bushfire offered by the door, as this will measure how well it holds up under heat and how well it insulates the home from a fire. If you live in an area where bushfires or forest fires or any other such fire is a high risk, be sure to check the BAL rating and invest in a high-quality door that will protect your home.
