A Special Message FromPresident General
Merry Ann T. Wright
DAR National Headquarters
Iconic Architecture
The striking exterior marble columns and the beautiful DAR Library ceiling are the most emblematic architectural features of the DAR National Headquarters historic building.
Skylight vs. Lay Light

Serious Deterioration Discovered
From the floor of the DAR Library, the lay light appears fine, but inspections from the top side of the lay light reveal structural deterioration which will require extensive and immediate restoration.
Architect Evaluation Report
“It is actually remarkable that
pieces of glass have not
fallen to the
Library floor.”
- Quinn Evans Architects
• $1.2 million dollars
• 9 month estimated completion time
• Critical to start project immediately or risk losing the lay light entirely
• Raising funds through the President General’s Project
“Keeping The Roof Over Our Heads”

Earthquake damage prompted
inspections that led to discoveries
of deterioration in the lay light
Lay Light Structural Deterioration
• Metal webbing - called “zinc cames” - used to keep the glass in place is deformed
• This bowing and bending from the original flat surface is called “displacement”
• Problem caused by gravity and exacerbated by extreme heat and improper
repairs made in the past
• Adds stress to the lay light panels and creates destabilization
DAR Library Lay Light Problems
Cracked Glass• Extreme displacement has resulted
in glass breakage
• Improper ventilation which led to
extreme heat exacerbated cracking
• Cracks in the panes could become
hazardous by releasing from the zinc
cames and falling to the library floor
DAR Library Lay Light Problems
Cracked Concrete
DAR Library Lay Light Restoration
Cracking around the steel beams which hold the panels in place only serves to further destabilize support for the panels.
Support wires were added in inappropriate locations causing the zinc cames to pull from the glass adding stress and causing destabilization.

Proper placement at an intersection of zinc cames
Improper placement
DAR Library Lay Light Problems
• Blowing rain can enter the cupola and cause water leakage resulting in glass staining
• Improper ventilation traps in heat
Deteriorating Cupola
DAR Library Lay Light Problems
Corrosion
• Moisture from leaking cupola has lead to corrosion
• Severe corrosion has destabilized the solder joints and zinc cames in all 25 panels
DAR Library Lay Light Problems
DisplacementThe lead panels holding the glass are bowing and bending away from the horizontal support bar. It should be nearly parallel to the support bar but on many panels there is significant displacement or “sway”.
DAR Library Lay Light Restoration
• Work could take up to
9 months
• 25 panels of glass to be
removed and restored
individually
• Requires highly
specialized skills
performed by craftsmen
• Scaffolding will be required, but we’ll keep the DAR Library open and as accessible to researchers as possible!
DAR Library Lay Light Restoration
Restore to Original Historic Beauty
President General’s Project
The DAR Library Lay Light Campaign will be part of the overall
President General’s Project restoration efforts
Successful roofing projects as well as repairing, restoring and cleaning exterior areas of the Headquarters complex have been completed but more critical work is still needed and will only be achieved with your support.
• Contributions to the President General’s Project
will help support the lay light
project as well as other
important initiatives
• Donor Wall recognition for
those donating the various
designated gift amounts
• Supporters who contribute
$1,000 or more will receive the
Benefactor Pin and special recognition at Congress
President General’s Project
• 25 seven-foot square panels
• $40,000 donation
(group or individual)
supports the cost for
refurbishing one panel
• Permanent recognition in the
DAR Library will honor those
able to donate the $40,000
required to sponsor a square
Sponsor a Lay Light Square
Your support will ensure that generations of future Daughters will be able to cherish the
historic and breathtaking DAR Library lay light.
