Frequently asked questions
-
Which windows are best for hot humid climates?
The best windows for hot and humid climates are ones that are energy efficient. Models that are improperly sealed can cause heat and humidity to seep in, resulting in a rise in temperature inside your home, which will cause your air conditioner to work twice as hard to keep you cool. It can also create moisture issues that can lead to the growth of dangerous substances, such as mold. When selecting the right windows for hot humid climates, start by looking at the type of frame and glass you will use. Wood frames might cost a little more, but they are also very efficient.
-
Should I choose double or triple glazed windows?
Triple-pane windows are more expensive and heavier, but they offer more thermal protection, and the added cost will likely be recouped in energy savings. You will certainly be more comfortable, and reduce the potential for moisture damage due to condensation on windows.
-
Which windows are most thermally efficient?
Window frames have become better insulated and more durable during the last years, air seals are better, and gas-filled cavities between double and even triple panes are the norm. As long as you choose good quality windows, all PVC, aluminium and wood windows are a good option.
-
What are double glazed windows?
Double glazing is made up of 2 separate panes of glass with a space in between. Most often, the gap between each pane of glass is filled with argon, an inert gas that is a poor conductor of heat. When all these components are put together, the glass combined with the argon-filled space creates a barrier between the outside and inside, preventing droughts and making your home more thermally efficient.
