Staying on Top of the Code Requirements in the
Ever-Changing World of Windows Doors Who
Said It Would Be Easy?
3
How the Codes Vary between the Different Groups

• Hurricane activity prompts code bodies to adopt
  these requirements
• High Design Pressures (DP Ratings) Required for
  Windows Doors
• Windborne Debris Protection (Impact Resistant
  Window Door Systems)
• Combination of Requirements (Energy Efficiency
  and Windborne Debris)

4
Main Building Codes Being Referenced

• IBC (International Building Code)
• Code referenced for commercial industry
• IRC (International Residential Code)
• Code referenced for residential industry
• FBC (Florida Building Code)
• Code referenced for state of Florida

5
What Do These Codes Mean to Window Door
Manufacturers Consumers?

• Require windows doors to meet minimum wind
  loads as determined in accordance with ASCE 7-98
  (American Society of Civil Engineers)
• Windborne debris regions require impact-resistant
  protection
• Windborne Debris Regions As Defined in ASCE 7-98
• Windspeeds are 120 mph or greater OR 110 mph
  within a mile of the coast
• Panhandle only has windborne debris requirements
  for areas within 1 mile of the coast (lessened
  through legislation)

6
New Requirements for Windows and Doors
MandatedProduct Design Pressure and Windborne
Debris for Specified Regions

• Window and door products are required to comply
  with high design loads to resist pressurization
• Glazed openings must be protected with
  impact-resistant coverings to prevent flying
  debris from penetrating through the glazing or
  designed for internal pressures
• Impact-resistant shutters/panels
• Impact-resistant glazing system
• EXCEPTIONNo internal pressure designs allowed in
  Dade or Broward Counties
• Requires products to pass missile impact test and
  cyclic pressure test

7
What Is Design Pressure?

• Represents wind load pressure for which the
  product is designed
• Incorporates a safety factor of 50
• DP50 is tested at 75 psf
• Positive and negative design pressure
  requirements for coastal areas water performance
  must meet the positive pressure required for
  structural design

8
Difference in Design Pressure Requirements in
Doors Vs. Windows

• Windows and glass doors require air, water and
  structural testing to meet overall design
  pressure rating
• Water penetration is determined at 1/10th of
  structural test pressure (IE DP50 tested at 75
  psf has water applied at 7.5 psf)
• Exterior Entry door assemblies are only required
  to meet a structural design pressure rating
• EXCEPTIONDade/Broward counties require
  air/water/structural testing

9
How To Improve Design Pressure on Window/Door
Products

• Frame Materials
• Overall Design (Increased sill height, jamb
  thickness, interlocks, etc.)
• Increased Glass Thickness/Strength
• Increased Sill Height for Water Performance
• Hardware (Additional locks, snubbers, upgraded
  pivot pins, etc.)

• And We Thought Hurricane Andrew Was Our Worst
  Nightmare
• August, 1992
• 23 Deaths
• 25,000 Homes Destroyed
• 135,000 Homes Damaged
• 160,000 People Homeless
• 25 Billion Dollars Damage

19
Floridas 2004 Hurricane Train Tests the Codes

• Hurricane Charley (145 mph)
• Worst hurricane in 12 years 27 confirmed deaths
  10,000 homes destroyed 16,000 with major damage
  estimated damage was 14 billion
• Hurricane Frances (105 mph)
• 18 deaths in Florida and Georgia 25,000 Homes
  Destroyed estimated damage was 10 billion
• Hurricane Ivan (130 mph)
• 20 deaths in Florida estimated damage was 20
  billion
• Hurricane Jeanne (120 mph)
• 6 deaths estimated damage was 12 billion

20
Paths of 2004 Florida Hurricanes
21
2005The Trend Continues
22
So Why Is There Still Damage Even After The New
Codes Were Implemented?

• New codes apply to new construction only
  (accounts for only 3 of overall structures in
  Florida)
• Poor enforcement of the codes (still struggling
  in some areas)
• Potential deficiencies in the codes (IE
  Allowing for designing for internal pressures,
  lack of windborne debris requirements in the
  Panhandle area more than 1 mile from coast, wind
  zone pressures not sufficient, etc.)

23
Design for Internal Pressure

• Connections are strengthened further for higher
  internal pressures when impact protection is not
  utilized
• Applies to windborne debris regions outside of
  Dade and Broward counties
• Assumes all glazed openings FAIL, leaving
  structure open to the elements (driving wind and
  rain)
• NOTEOn June 8, 2005 Governor Bush signed a
• bill removing the allowance for
  design for internal pressures

24
Windborne Debris Requirements
So How Can Builders And Architects Meet The Codes?
25
The Three Most Common Methods

• Window and Door Impact-Resistant Systems
• ASTM E1886/E1996 referenced in I-Codes and FBC
• Miami-Dade TA 201, 202 and 203 required in Dade
  and Broward counties
• Plywood Covers
• Accordion or Roll Down Shutters
• NoteThe use of laminated glass in a DP rated
  product does not constitute an impact-resistant
  system. The entire system must be tested to the
  appropriate standard in order to be considered
  impact-resistant

  Analysis Cannot be used in Dade/Broward
  Counties
• Provides a more cost-effective means to
  mull/stack impact window configurations to be
  produced (size limitations in accordance with
  engineering guidelines). The LVL mullion is not
  approved for use with any door products.

42
Key Element for SuccessInstallation
43
Proper Installation Is Critical

• High DP ratings impact-resistant products may
  require specific installation (often more
  in-depth than standard product installation)
• ¼ maximum shim space
• Additional anchoring through nailing fins
• Different anchoring method (IE screws instead
  of nails)
• Longer anchors
• Use of installation brackets
• Installing anchors through sash/frame into the
  openings

44
Certified Installation Methods

• Products tested in accordance with AAMA (American
  Architectural Manufacturers Association) have
  certified methods of installation noted in body
  of test reports
• Installation which differs from the certified
  details will not assure similar product
  performance and will not be accepted in areas
  requiring specific design pressure ratings

Why Windows Instead of Shutters or Plywood?
48
Windows Vs. Plywood

• Plywood requires extra storage room when not in
  use -- Windows do not.
• Plywood covers require installation as the storm
  approaches. If youre away from home, you will
  pay someone to install plywood covers -- Windows
  are always in place.
• If you are not able to get your plywood installed
  prior to a storm, an insurance company could deny
  claims for damage -- Windows are always in place.
• Plywood covers require some method of attachment
  to the home (screws/brackets/etc.) that are
  unsightly and detract from the appearance (and
  perhaps value) of a home -- Windows add to the
  appearance (and value) of a home.

49
Windows Vs. Shutters

• Shutters need to be closed as the storm
  approaches. If the storm knocks power out, is
  there someone to activate the shutters? Will
  exposure to salt air corrode the shutters where
  they will not operate? -- Windows are always in
  place.
• Shutters are attached to the exterior of the home
  and can detract from the appearance (and value)
  of the home -- Windows add to the appearance (and
  value) of a home.
• If you are away from home prior to a storm, you
  will need to find a way to close your shutters --
  Windows are always in place.
• Shutters come in limited shapes Windows come in
  virtually any shape you can imagine.

50
That Is Why Windows!
51
Additional Benefits of Laminated Glass
52
Multi-Talented GlassLaminated glass is a high
performance solution to manyarchitectural design
challenges due to itsmulti-functional
benefits.
53
The Sound Barrier
With Peachtree windows featuring laminated
glass, irritating sounds such as traffic and
airport noise are reduced.
54
The Sound Barrier

• Laminated glass has been tested and is shown to
  reduce sound transmission.
• In a product with laminated glass versus annealed
  glass, the Sound Transmission Class (STC) value
  improves by approximately 11.
• Laminated glass can reduce perceived noise by
  up to 50.

55
Safety
Life happens. Windows break. Standard
annealed glass (found in most homes) shatters
like this one. Peachtree laminated glass resists
impact.
56
Savor The Security
Not every window is cut out to protect homeowners.
Peachtree StaySafe Impact windows
with laminated glass are.
57
Sunscreen for the Home
Peachtree windows with laminated glass have been
proven to effectively filter out up to 99 of
harmful Ultra-Violet (UV) radiation.
58
Sunscreen for the Home
Laminated glass has no adverse affect on the
health of indoor plants. In fact, laminated
glass is commonly used in greenhouses and atriums
to help protect flower color and reproductive
development from the damaging effects of UV
radiation. Photoreceptors in plants are still
able to absorb sunlight that the interlayer
allows to be transmitted.
59
Sunscreen for the Home
Perhaps the easiest way to relate the solar
protection of laminated glass is to compare it to
a common household item suntan lotion. The UV
protection of Peachtrees laminated glass is
equivalent to SPF 72.
60
Weather unfit for man or beast
Our doors and windows with laminated glass
pass the most stringent hurricane codes in the
United States.
61
Hard Working Glass

• Laminated glass
• provides these additional benefits
• 24 Hours per Day
• 7 Days per Week
• 52 Weeks per Year
• without the need to be applied or
• activated when you need the benefits!
