Minimizing Condensation
Note: Please reference EFCO's "Understanding Condensation" brochure which can be obtained
through your EFCO representative.
Condensation will form on any surface when unfavorable conditions (interior temperature and
relative humidity and exterior temperature) are present. When the formation of excessive condensation
is a concern, it is highly recommended that a design professional is utilized to perform an analysis of
the shop drawings to recommend the best possible installation methods. Please contact your EFCO
representative for information on EFCO's Thermal Analysis Services.
Many current installation practices lead to an increase in the possibility of the formation of
condensation. Though not all inclusive, the list of examples below illustrates conditions under which
condensation is likely to occur:
1. Bridging system thermal break with non-thermally broken metal flashing or lintels that
are exposed to the exterior
2. System exposure to cold air cavities
3. Interior relative humidity levels not maintained at recommended levels, see EFCO’s
“Understanding Condensation” brochure
4. Inadequate separation between system and surrounding condition at perimeter
5. Product combinations during the shop drawing stage that result in bridging thermal
breaks of one or all products involved
Note: These installation instructions are a supplement to the approved final shop
drawings and are to be used in conjunction with those drawings.

Duracast Pressure Plate Installation Instructions
Section I: General Notes and Guidelines
I. HANDLING / STORING / PROTECTING DURACAST - The following precautions are
recommended to assure early acceptance of your products and workmanship.
A. HANDLE CAREFULLY - Store with adequate separation between components so
the material will not rub together. Store the material off the ground. Protect materials against weather elements and other construction trades.
B. KEEP MATERIAL AWAY FROM WATER, MUD, AND SPRAY - Prevent cement,
plaster, and other materials from contacting with and damaging the finish. Do not
allow moisture to be trapped between the finished surface and the wrapping material.
C. PROTECT MATERIALS AFTER ERECTION - Wrap or erect screens of plastic
sheeting over material. Cement, plaster, terrazzo, and other alkaline materials are
very harmful to the finish and are to be removed with soap and water before hardening. Under no circumstances should these materials be allowed to dry or permanent staining will occur.
D. CUTTING OF DURACAST - Duracast can be cut with a standard miter saw using
a carbide blade; however, the life of the blade life will be shortened significantly
due to the high glass content of Duracast. For best results use a diamond tipped
or concrete blade for extended blade life.
II. GENERAL GUIDELINES - The following practices are recommended for all installations:
A. REVIEW APPROVED SHOP DRAWINGS – Become thoroughly familiar with the
project. Shop drawings govern when conflicting information exists in these installation instructions.
B. INSTALL ALL FRAMING MATERIAL PLUMB, LEVEL, AND TRUE – Proper
alignment and relationships to benchmarks and column centerlines, as established
by the architectural drawings and the general contractor, must be maintained.
C. The sequence of erection should be coordinated with the project superintendent to
prevent delays and minimize the risk of material damage. Note: If preset an-
chors are required, coordinate and supervise anchor placement with the
general contractor.
D. Verify that all job site conditions and accompanying substrates receiving the instal-
lation are in accordance with the contract documents. If deviations occur, notification must be given IN WRITING to the general contractor and differences resolved before proceeding further with the installation in the questionable area.

F. Follow EFCO framing installation and glazing instructions.
G. Verify contents of all material shipments received upon their arrival. Verify quantity
and correct finishes. NOTIFY EFCO IMMEDIATELY OF ANY DISCREPANCIES
OR DAMAGE THAT MAY HAVE OCCURRED.
H. Throughout these instructions the term “SEALANT” will appear. For the purposes of
these instructions, sealant is to be defined as the following:
SEALANT - A weather resistant, gunnable liquid filler which when cured provides a
resilient, flexible (± 50% movement capability) air and water seal between similar
and dissimilar materials.
All sealant must meet ASTM C 920, CLASS 50.
BUTYL SEALANT- A non-skinning, non-hardening material (NAAMM Reference Standard 5C-1).
NOTE: All sealant must be compatible with all surfaces on which adhesion is re-
quired, including other sealant surfaces. All frame surfaces should be clean,
dry, dust, and frost free. If a primer is required, it must be applied to clean
surfaces. All perimeter substrates shall be clean and properly treated to receive sealant.
This system is designed and has been tested to utilize butyl or silicone sealants at all internal joineries, i.e., joint plugs, gasket intersections, etc.
Regardless of the sealant used, the customer should contact the sealant
manufacturer to determine compatibility and adhesion. Follow sealant manufacturer's proper application procedures and quality assurance programs for
weather sealing.
Maintain caulk joints as shown in the approved shop drawings. Unless
specified otherwise, most sealant manufacturers recommend a 3/8” minimum perimeter caulk joint. A 3/4” minimum joint is recommended at the
head condition to accommodate thermal expansion and contraction.
Anchoring surfaces of perimeter construction must be level and plumb within
the adjustable limits of the head, jamb, and sill framing.
