So much has changed in our product
line we are updating this page. Thanks for visiting.
Question: What storm protection is best for us?
We are in the process of up dating this page. The following information is used
to support our opinions as to what is the best protection for your dollar
invested. Secondly how our storm protection products apply to your requirements.
There
are four basic concerns for rating protection chartists of materials used to
protect windows and doors on a dwelling.
First
is wind. Understanding wind velocities and destruction caused at various
different wind conditions.
Second
repair or replacement costs in the event something would happen.
Third
is the investment cost of protection with relation to insurance rebate offers.
Fourth
is impact rating.
Impact rating is placed in the fourth position for the following reasons:
Considering the majority of buildings and windows in the majority of location
through out the world impact does not rate as important as one perceives. Even
a building in what is to be considered a hi impact area has some windows that
are not venerable to damage from flying objects. Two examples: 1. Two buildings
along side of each other make it very difficult for a flying object to stop –
make a direction change for a direct hit on windows. Resulting in less impact
protection is needed. 2. One may never be exposed to the type of flying item
destruction as seen on TV.
Only a few windows may actually be located in a position requiring high impact
protection.
More on high impact ratings will be discussed later in this section.
We address wind first as it is most likely to occur at your location. Simply
stated we know there will be high winds but we don’t know when and how strong.
Referencing to the above Hurricane Strike Frequency
Map*. This map provides us with some historical based data for anticipation of
the future. The information is not presented in and effort to say this is the
way it shall be but an indication of what one could anticipate.
With
some understanding as to how often we then turn our thoughts to how strong or
how powerful. The Saffir-Simpson Hurricane Scale, as shown below, is the
industries standard rating scale. Reading this scale one can begin to understand
and then use this knowledge to make a more reasonable decision as to how much
investment should be made for protection.
In many
cases the age and condition of a building does not warrant window protection
above Category Three.

State of Florida has established a program emphasizing the importance of wind
protection.If you are interested in finding out how or what your home requires

The Saffir-Simpson
Hurricane Scale
The Saffir-Simpson Hurricane Scale is a 1-5 rating based on the hurricane's
present intensity. This is used to give an estimate of the potential property
damage and flooding expected along the coast from a hurricane landfall. Wind
speed is the determining factor in the scale, as storm surge values are highly
dependent on the slope of the continental shelf and the shape of the coastline,
in the landfall region. Note that all winds are using the U.S. 1-minute average.
Category One Hurricane: Winds 74-95 mph (64-82 kt or 119-153 km/hr). Storm surge
generally 4-5 ft above normal. No real damage to building structures. Damage
primarily to unanchored mobile homes, shrubbery, and trees. Some damage to
poorly constructed signs. Also, some coastal road flooding and minor pier
damage. Hurricane Lili of 2002 made landfall on the Louisiana coast as a
Category One hurricane. Hurricane Gaston of 2004 was a Category One hurricane
that made landfall along the central South Carolina coast.
Category Two Hurricane: Winds 96-110 mph (83-95 kt or 154-177 km/hr). Storm
surge generally 6-8 feet above normal. Some roofing material, door, and window
damage of buildings. Considerable damage to shrubbery and trees with some trees
blown down. Considerable damage to mobile homes, poorly constructed signs, and
piers. Coastal and low-lying escape routes flood 2-4 hours before arrival of the
hurricane center. Small craft in unprotected anchorages break moorings.
Hurricane Frances of 2004 made landfall over the southern end of Hutchinson
Island, Florida as a Category Two hurricane. Hurricane Isabel of 2003 made
landfall near Drum Inlet on the Outer Banks of North Carolina as a Category 2
hurricane.
Category Three Hurricane: Winds 111-130 mph (96-113 kt or 178-209 km/hr). Storm
surge generally 9-12 ft above normal. Some structural damage to small residences
and utility buildings with a minor amount of curtainwall failures. Damage to
shrubbery and trees with foliage blown off trees and large trees blown down.
Mobile homes and poorly constructed signs are destroyed. Low-lying escape routes
are cut by rising water 3-5 hours before arrival of the center of the hurricane.
Flooding near the coast destroys smaller structures with larger structures
damaged by battering from floating debris. Terrain continuously lower than 5 ft
above mean sea level may be flooded inland 8 miles (13 km) or more. Evacuation
of low-lying residences with several blocks of the shoreline may be required.
Hurricanes Jeanne and Ivan of 2004 were Category Three hurricanes when they made
landfall in Florida and in Alabama, respectively.
Category Four Hurricane: Winds 131-155 mph (114-135 kt or 210-249 km/hr). Storm
surge generally 13-18 ft above normal. More extensive curtainwall failures with
some complete roof structure failures on small residences. Shrubs, trees, and
all signs are blown down. Complete destruction of mobile homes. Extensive damage
to doors and windows. Low-lying escape routes may be cut by rising water 3-5
hours before arrival of the center of the hurricane. Major damage to lower
floors of structures near the shore. Terrain lower than 10 ft above sea level
may be flooded requiring massive evacuation of residential areas as far inland
as 6 miles (10 km). Hurricane Charley of 2004 was a Category Four hurricane made
landfall in Charlotte County, Florida with winds of 150 mph. Hurricane Dennis (pdf)
of 2005 struck the island of Cuba as a Category Four hurricane.
Category Five Hurricane: Winds greater than 155 mph (135 kt or 249 km/hr). Storm
surge generally greater than 18 ft above normal. Complete roof failure on many
residences and industrial buildings. Some complete building failures with small
utility buildings blown over or away. All shrubs, trees, and signs blown down.
Complete destruction of mobile homes. Severe and extensive window and door
damage. Low-lying escape routes are cut by rising water 3-5 hours before arrival
of the center of the hurricane. Major damage to lower floors of all structures
located less than 15 ft above sea level and within 500 yards of the shoreline.
Massive evacuation of residential areas on low ground within 5-10 miles (8-16
km) of the shoreline may be required. Only 3 Category Five Hurricanes have made
landfall in the United States since records began: The Labor Day Hurricane of
1935, Hurricane Camille (1969), and Hurricane Andrew in August, 1992. The 1935
Labor Day Hurricane struck the Florida Keys with a minimum pressure of 892 mb--the
lowest pressure ever observed in the United States. Hurricane Camille struck the
Mississippi Gulf Coast causing a 25-foot storm surge, which inundated Pass
Christian. Hurricane Katrina (pdf), a category 5 storm over the Gulf of Mexico,
was still responsible for at least 81 billion dollars of property damage when it
struck the U.S. Gulf Coast as a category 3. It is by far the costliest hurricane
to ever strike the United States. In addition, Hurricane Wilma (pdf) of 2005 was
a Category Five hurricane at peak intensity and is the strongest Atlantic
tropical cyclone on record with a minimum pressure of 882 mb.
That’s all for now. FROM TIME TO TIME WE WILL BE ADDING TO THE INFORMATION TO
