Is Saint Petersburg in a Wind Borne Debris Region?

Yes. St. Pete falls squarely within the wind-borne debris (WBD) region for Pinellas county. If you check the My Florida Fact map outlining the wind borne debris regions in Florida, all of Pinellas is part of the 140 mph wind band, making Saint Petersburg a WBD region.

What St. Pete Homeowners Should Know About WBD Regions

Living in a wind-borne debris region brings some challenges. Here are a few things that you should be aware of for your St. Pete home:

140 Miles Per Hour… or More

In a WBD region, properties will face sustained winds of 140 mph or more. Since Saint Petersburg falls in this zone, homeowners need to take precautions against flying debris.

Evacuation Routes

Homeowners in one of Florida’s wind borne debris regions may be required to evacuate when a major storm hits. Check out the Pinellas County Know Your Zone map to see your evacuation zone.

Flying Debris Risks

While strong winds do pose a danger to homes, sometimes it’s what the wind is blowing that poses the greatest threat. Hurricane-force winds can pick up and throw rocks, loose boards, and vehicles.

Sliding Windows

Strong rollers and locking mechanisms make these windows easy to open and close while standing strong against high-speed wind and debris.

Picture Windows

These windows remain fixed in place, trading the ability to open for a greater field of view and extra rigidity during heavy storms and hurricanes.

Awning Windows

These windows are similar to casements, but swing open vertically rather than horizontally. Get secure impact-rated awning windows for your home.

I reached out to Karoly for new sliding windows in my florida room and two exterior doors.  Karoly came out and spent quite a while getting all the measurements right.  That makes you feel good.  When the installers came out, two days and done.  Windows look great and the doors are solid and close tight.  Everything is now impact and hurricane rated.  I got my insurance discount.  Thanks Karoly!

 Trustindex verifies that the original source of the review is Google. I am very hard to please as I pretty much expect close to perfection.  From a serious point I just want a TEAM that cares and gives it their best.  Mistakes happen.  However today I had Hurricane windows placed by Karoly.  Actually from the very beginning it was like dealing with a family.  In all my dealing with different companies A/C etc they far outshined any company I have ever dealt with.  My techs were  Vili, Zoli and Christian.  They gave 150%, were very clean, cared about our house and did exquisite workmanship.  1,000% incredible and guess what they are not my relatives.  LOL

I will never be able to brag enough about how superior this company is. My husband and I interviewed at least seven window companies, all full of similar products of PGT or other hurricane safe Windows. We became window experts on our own with the knowledge we absorbed comparing apples to apples.

Karoly was the final company we met with and Austin presentation was simple and he showed us a sample and did all the measurements. He explained the Simonton brand very well and the warranty they offer cannot be beat. We visited their showroom and met with Jesse  to really look at products. Our decision was quick and easy and the price was better than their competitors.

We completed all the paperwork with Richy and Angela and the rest of the wonderful staff. Installation day came and we met the fantastic installers that were so kind and clean. In 3 days our job was done. The day after that inspector came and passed us and one week later Karoly came back to complete final installation of some parts and now it’s all finished.

These windows have changed our home completely. Not only did we work with the best contractor and save money we also gained a more beautiful home and it’s so quiet! No barking dogs or loud traffic or thunder anymore just peaceful tranquility!!!

Thank you everyone at Karoly for making us so happy!!! I promise to call you again for all my other houses!! This was the best thing we’ve ever done without a doubt .

Sincerely,
Cheryl & Doug Sigmon

Thrilled with our new windows and doors. Dealing with Karoly, from no pressure sales, installation, and close out was great. They kept us informed and did everything they said they would. Highly recommend Karoly Windows and Doors!

 Trustindex verifies that the original source of the review is Google. After researching a few companies, I decided to go with Karoly.  They replaced 19 windows and 3 sliders with Sinomton Stormbreaker Plus 300VL and Simonton Maxview.  I enjoyed reading the information they had on their website and pleased to see this is a family owned business with emphasis on quality work and customer satisfaction.  Employees were pleasant and professional and answered my questions.  It has only been almost 2 years since installation and from my experience thus far, I would highly recommend Karoly.

I couldn't be happier with my experience with Karoly Windows & Doors! They replaced all of my windows along with two doors, and the entire experience exceeded my expectations. From start to finish, everyone was professional, friendly, and truly cared about doing the job right.

The installation crews were outstanding. They were hardworking, respectful of my home, paid attention to every detail, and the quality of their workmanship was exceptional. I'm extremely pleased with the quality of the window replacement, the beautiful new doors, and the finished results.

I was so impressed with the company that I've already recommended Karoly Windows & Doors to several of my neighbors. It's refreshing to work with a company that delivers exactly what they promise. If you're considering window replacement, I highly recommend Karoly Windows & Doors. They are a true first-class company, and I couldn't be more satisfied with the entire experience.

St. Pete Wind Borne Debris Region FAQs

What Is a Wind Borne Debris Region?

A WBD region is an area defined by the state government of Florida as being subject to winds of 140 miles per hour or more. Much of the coast of Florida is designated as a wind borne debris region under the Florida Building Code.

Saint Petersburg is solidly within the 140+ mph band of the wind borne debris region map. Because of this fact, it’s important to ensure that your home is protected by reliable impact windows installed by the most trusted impact window replacement company in St. Pete!

Can High-Speed Winds Really Throw Cars?

Yes. A strong enough wind can pick up and throw a car. How much wind is required to do this? That depends on the vehicle in question. The larger and lighter-framed the vehicle is, the easier it will be for strong winds to move or even lift it off the ground. The smaller and denser a vehicle is, and the more aerodynamic it is, the harder it will be for the wind to throw.

ABC7 Chicago posted a video showing a mathematical equation that can be used to calculate how much wind is needed to move an object. The required wind to move an object is equal to the square root of the product of 195 times the weight of the object over its area in square feet.

Under this formula, a car weighing 2871 lbs with a surface area of 69 sq. ft. would only require 90 mph (2871/69 = 41.60869565, multiply by 195 to equal 8,113.695652, the square root of which is 90.07) winds to make the car move. Much higher, and the car could actually be physically lifted off the ground or toppled.

If a vehicle weighing over a ton can be lifted and moved with only 90 mph winds, imagine how much other debris a major hurricane can pick up and throw.

What Is Wind-Borne Debris?

Wind-borne debris can be literally anything that a strong wind can pick up and throw. It can include things like rocks, tree branches, whole trees, trash cans, trampolines (very common because of how large and light they are, making them easy to pick up and throw), loose nails, pieces of other houses, cars… the list of possible wind-borne debris objects is endless.

This is why impact windows should be tested using both the Large and Small Missile Impact testing standards to show off their versatility in resisting hits from differently-sized and shaped objects.

While no window will be proof against all impacts, hurricane-rated impact windows have failsafe measures that account for the top layer of glass breaking to continue protecting your home. For example, impact windows typically have a second layer of glass and a layer of flexible laminate material that absorbs impacts without breaking.

What Are the HVHZ Zones in Florida?

There are currently only two counties in Florida that are classified as high-velocity hurricane zones (HVHZs): Miami-Dade County and Broward County. These two areas are considered especially high-risk for high-speed hurricane winds, so windows and doors installed there need to be especially strong and durable to comply with local building codes.

However, homes in other areas of Florida can still benefit from installing HVHZ-rated windows and doors, as Miami-Dade and Broward aren’t the only counties that may face Cat 5 storms.

How Long Does a Window Installation Take?

When hurricane season is close (or currently active), it’s important to get your new hurricane windows installed in a timely manner so you can protect your home from wind-borne debris and other hurricane hazards.

So, how long does it take to install a new hurricane window? The answer is: It depends.

The specific windows you choose, the manufacturer, global supply chain issues, local weather, and the availability of installation crews can all affect the timeline for your new window installation. Once started, however, a typical four-person work crew can install between eight and fifteen windows per day (depending on size and where the windows need to be installed). Most jobs finish within half a week or less once started.

When you request a quote for window installation from Karoly, the installation tech who does your in-person assessment can provide you with a timeline for your installation project.

Why Use Custom Windows over “Standard” Ones?

Why not go to a hardware store to buy your own windows? Especially if you have a standard window opening? Because there’s more to window installation than getting a new window that’s roughly the right size for your opening.

New windows need to be shimmed, insulated, caulked, taped off, leveled, and carefully secured to ensure that they won’t fall out from a stiff breeze or let in moisture from the outside.

Also, in some homes, a structure may ‘settle’ over time, causing window openings to warp slightly with the building frame. Installing windows without accounting for this warping may lead to gaps, cracked windows, and worse.

At Karoly, we always perform an in-person inspection of your window openings before providing a quote for service. This way, we can account for any oddities with your window openings in the initial quote for service so there aren’t any surprises in your bill.

Why Buy New Impact Windows?

The reasons to buy new impact windows rather than simply replacing the glass in your existing windows are numerous. First, impact resistance is a system. Just changing out non-impact glass for tempered glass doesn’t automatically make the whole window assembly impact-resistant. The frame, locking mechanisms, and other materials all need to be designed around impact resistance to ensure that a window can take storm impacts without failing.

Second, window replacement can help you maximize your home’s energy efficiency. Older aluminum window frames transfer a lot of heat into your home, making it warmer. This means that your air conditioning system needs to work harder to maintain a comfortable temperature, increasing the amount of energy it uses. Replacing aluminum windows with vinyl-framed windows that restrict the amount of heat transferred to your home can save you money on your energy bills.

Finally, some homeowners choose to replace their windows simply to enhance the curb appeal of their home. Replacing windows entirely, frame and all, gives you more control over the appearance of your windows so they more closely match your style preferences.
