Hurricane Resistant Windows: Cost and Benefits


Hurricane resistant or storm proof windows are made of impact resistant glass, which contains a layer of polyvinyl butyral (PVB) between two glass slabs. The most effective type of impact resistant window is the inner membrane window. Impact resistant glass is likely to break on impact, but will remain attached to the inner membrane along with the window frame.

There is always an alternative to using a shatter resistant film that covers the window glass, which will prevent the glass from breaking.

Hurricane Windows Cost

Hurricane resistant windows can increase the total cost of construction. However, at the same time, they will offer great protection during storm season and can be very helpful in protecting property and may be the reason for how to get a reduced premium on the cost of your insurance. A good hurricane window cost will be between $ 40 and $ 55 per square foot, and this will include the frame and the hurricane proof glass. Some studies have shown that by installing hurricane windows, the construction cost will increase by a few thousand dollars on a new home. On average, a 60 "x 80" hurricane impact door size can cost around $ 1,900, while a 72 "X 80" sliding window is around $ 1950.

Hurricane resistant material guide for windows

The main options to consider as hurricane resistant windows are aluminum, vinyl, and wood. Aluminum is probably the strongest of the three, providing excellent results in hurricane conditions. Their main drawback is that they will have to be painted over time.
Vinyl hurricane proof windows are a great cost-effective solution, offering great insulation benefits, although the industry is still unsure how to recycle them. Lastly, wood can offer great energy efficiency, but its maintenance cost is the highest among these three options, not to mention that they will be susceptible to deformation over time.

Types of hurricane resistant window glass

The four main types of impact resistant glass are identified by the laminating procedure or the window interleaving procedure. PVB, Polyvinyl Butyral, is the most widely used product on impact glass market as it works well when impacted and absorbs impact. PVB with a PET coating is a very resistant product, but its manufacturing process is quite challenging, making it an economically less viable product. Sentry Glass Plus is more expensive than PVB, typically used in some federal construction or specialized areas that require bullet and bomb resistant glass. Finally, the resin laminates where a liquid is poured between two layers of glass and allowed to cure.

Advantages of Hurricane Resistant Windows

Hurricane resistant windows are manufactured with a polyvinyl membrane in the middle layer capable of withstanding storm winds of up to 200 miles per hour.
These windows could also provide energy efficiency to your structure, including minimal sound disturbance and UV protection.
Some of the biggest benefits of impact resistant windows are:
·         Come in different styles and sizes
·         Provide permanent protection against tornadoes, storms and hurricanes at any time
·         Its high resistance prevents the glass from breaking into large sharp pieces
·         When glass cracks create a 'spider-like' cracking pattern
·         A much higher sound insulation rating due to its damping effect
·         Blocks 99% of transmitted UV light
·         Some insurance companies may offer premium discounts of up to 45%

Disadvantages of Hurricane Resistant Windows

Impact resistant windows can also be expensive and sometimes too expensive. Adding an average of $ 55 per square foot, impact resistant windows could add a couple thousand more to your construction project, but will eventually lower your insurance costs.
Tear resistant film could be used as an alternative, but it is less effective and could fail in extreme wind conditions. Much of the noise-reducing properties of laminated glass come from the air gap between two panels of the laminate, not from the vinyl layer itself. If windows are installed without the benefit of these air gaps, then the noise reduction properties are greatly reduced.

Impact Door Advantages - Hurricane Windows & Doors of Florida

Image
Families with children can help prevent noise from disturbing the neighborhood by installing impact doors. Not only does it prevent noise from entering the house, but it also helps prevent them from leaving the house as well. The installation of impact doors is one of the factors that must be considered to ensure that your home is safe, security against storms, theft or other form of natural disasters. For all those who have concerns about the hurricane, there is no need to ask more because the solution to their problem has been seen and can be provided at a much less expensive rate. Impact doors are very useful and give maximum protection to homes from any storm that comes. Hurricane impact doors are not only used to protect the home from storms, but they also come along with some of the most significant benefits. These impact doors help reduce the effect of noise pollution; which helps isolate noise. These gates are very useful for people who live near the str...

Is Your Home Already Protected From Hurricanes?

If you live in a coastal area or a region prone to cyclonic activity, you should know how devastating a hurricane can be. When it comes to preventing damage, it is easy to underestimate a hurricane after not having experienced it in a few years, however it is important that you take the time to prepare your family and property in the event of a storm. Protect your home during a hurricane. Thanks to the effects of global warming, hurricanes are taking much more strength. Which puts great pressure on your windows. Without a professional security system, your windows can easily break, leaving your property vulnerable to rain, and debris that can cause significant damage to your home. An anticyclone security system keeps everything off your property, while keeping you and your family safe. At this point you can ask yourself: And what makes it different from wood sheets? Even if you install them perfectly, they may not be strong enough to withstand the press...

What Does an Anti-Hurricane Window Look Like?

The windows in Florida do not support extreme weather phenomena. Probably where they suffer the most is on the coast, where the air is much more humid and is loaded with nitrate. Precisely because of this proximity to the sea we also run the risk of experiencing some gale, sudden winds, and rapids typical of the Bay of Biscay, although fortunately, they are not habitual or as destructive as a hurricane. But there are cities where its inhabitants are used to living under the real threat of tornadoes and hurricanes. And that's why in places like Florida or Mexico, companies offer windows and hurricane protection among their products, something totally unknown to us. Studies show that if a building's openings are preserved undamaged during a tornado, the chances of retaining the roof increase, reducing material damage. Following Hurricane Andrew, which wiped out the US in 1992, South Florida began developing building construction standards, including window manufacturing,...
