If you have a patio, a deck, or just a wide foyer, you might have a bigger door space than a normal door. So, instead of a normal door that swings open and closed, you might need double doors. Double doors are great because they provide maximum ventilation and light when you open them. They are also great if you need to move furniture into or out of your house since they offer a wide opening for moving wide furniture. However, they can be a liability when it comes to heating and cooling your house. A wide door offers a great thermal bridge. A thermal bridge is anywhere in your home that allows more heat to transfer than other parts of your house.
For example, if you have insulated walls but your door is not insulated, your door will likely be a thermal bridge. If you want to allow in a large amount of light while keeping your energy costs low, you should choose an energy-efficient door.
Glazing is the process of working with glass so a double-glazed door is one that has two panes of glass with a cushion of air between them. Air is not a very good conductor of heat so it is also fairly good insulation. With two panes of glass, heat will not transfer readily between the outside and the inside. That is a great way to reduce your energy costs. Furthermore, double-glazed glass is great for allowing in a large amount of light without allowing much heat to transfer. Therefore, you can keep the curtains open, which will allow in a large amount of light without allowing in the heat. You’ll be able to reduce the amount of time you spend with your artificial lights turned on.
Artificial lights only consume a few pennies per day but that can add up quickly. Good insulating bifold doors in Melbourne can help reduce the amount that you spend on lighting.
One of the best ways to reduce the amount of heat that you are allowing to transfer in and out of your house is to choose a door with welded joints. In many doors, the joints and connections are bolted or screwed together. While these might be efficient fasteners, they create tiny gaps where the two pieces meet. Those tiny gaps allow for heat to transfer. The transfer adds up over the course of several days and accounts for a lot of thermal bridging.
Lastly, you should look for a door that is made of insulating materials. The glass is important but the material of the frame is also important. The frame of the material needs to be made out of something that will help keep the heat from transferring from the glass into the house. Often, the glass panes will collect heat but the double glazing means that it won’t transfer to the other pane. A good frame material will absorb that excess heat.
These are a few of the ways to reduce the amount of heat transferred through glass doors.
