Impact Windows

Florida is prone to storms that can cause extensive damage to homes and businesses. But how do you protect your property from high winds and flying debris? One way is to install impact windows.

In fact, the state’s building code requires homeowners living a mile from the coast or in a high-risk hurricane zone to install impact windows. They should be able to withstand at least 150 mph winds. But even if you’re not within these areas, they can still benefit your property in many ways.

What Makes Impact Windows?

Impact windows are made with two or more layers of glass. The inner layer is usually a tough polyvinyl butyral (PVB) sandwiched between 2 layers of heat-strengthened or annealed glass. While the PVB is the most common material, sometimes SentryGlass Plus® (SGP) can still work.

It also has lamination, a process in which the multiple layers get bonded together with a heat and pressure treatment. The result is a much stronger window that prevents objects from penetrating within test load requirements.

Types of Impact Windows

Impact windows come in several types to cater to different functions and needs. Below are some of the most common ones:

  • Single/Double Hung Impact Windows

Arguably, the most popular choices in the market, these windows have an upper and lower sash that you can open and close vertically. As the name suggests, single-hung impact windows only have one sash, while double-hung windows have two.

These two options are also some of the most design-friendly and versatile windows available. They also come in various colors, allowing you to get a perfect match for your desired home aesthetic. The real genius of hung impact windows, however, lies in their simplicity, elegance, and ease of incorporation into any design.

  • Casement Impact Windows

Casement Impact WindowsUnlike single/double-hung impact windows that open vertically, casement impact windows open inwards and, in some cases, outwards. Depending on your preference, they swing open via a crank mechanism and a hinge on either right or left sides.

This design allows a clear and open line of sight without a horizontal brace bar in the middle, giving you an unobstructed view of your surroundings. They’re also airtight when closed, making them one of the most energy-efficient window options.

  • Picture Impact Windows

Picture impact windows are, well, exactly as the name suggests. They’re large windows that offer an expansive and picturesque view of your surroundings. They are usually large solid glass sheets with one open, specious pane.

Picture impact windows are perfect for living rooms and bedrooms as they provide an excellent natural light and ventilation source. They also make small spaces appear more open and airy, giving the illusion of a larger room.

  • Sliding Impact Windows

Also known as roller windows, these impact windows open horizontally via two panels that glide smoothly past each other. Sliding impact windows are an excellent option for tight spaces as they don’t need extra space to open.

They’re also easy to operate and are perfect for larger openings. Depending on window space, you can get them in 2, 3, and 4-panel options.
