There are a few things to consider when choosing a skylight for your home. The first is the size of the opening. You'll want to measure the area where you plan to install the skylight and then compare that to the sizes offered by different manufacturers. It's important to get a skylight that's the right size for your opening, because an improperly sized skylight can cause leaks.
Another thing to consider is the type of glazing or lens that you want for your skylight. There are several different types of glazing available, each with its own benefits and drawbacks. For example, some types of glazing block out more UV rays than others, so if you're concerned about sun damage or fading furniture, you might want to choose a type of glazing that offers more UV protection.
Finally, you'll need to decide on a frame material. Skylights are available with frames made from wood, aluminum, vinyl, or fiberglass. Each material has its own advantages and disadvantages in terms of durability, cost, and energy efficiency. Once you've considered all these factors, you should be able to narrow down your choices and find the best skylight for your home.
