Mini mizing 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 installation methods. Please contact
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.

SECTION I - GENERAL NOTES
The "Series 525" is a framing system that is designed for impact
resistance of windborne debris. It can be used as a single-span
storefront window wall, a punched opening system, or as a ribbon
window system. The system can be fabricated for both screw
spline and shear block construction.
The Series 525 system contains primarily stock length material
with in-the-field fabrication, or it may be fabricated in the shop for
delivery to the job site. Entrance doors are also an integrated
part of this system, utilizing frame members and hardware
support systems that accommodate doors and door hardware
that will withstand impact from windborne debris.
1.) Check the shop drawings, installation instructions, and glazing instructions to
become thoroughly familiar with the project. The shop drawings take precedence and
include specific details for the project. The installation instructions are of a general
nature and cover the most common conditions encountered.
2.) Check all materials on arrival and be sure you have everything required to begin
installation. See Section II "PARTS IDENTIFICATION" for parts cross reference.
3.) All work should start from bench marks and/or column center lines as established
by the architectural drawings and the general contractor. Installers should check
building construction for compliance with architectural documents to ensure the proper
window system foundation is available before installation.
4.) The term "sealant" as used in these instructions is defined as: A weather resistant,
gunable liquid filler, when dry, provides a resilient, flexible air and water seal between
similar and dissimilar materials. In these instructions Dow Corning 795 or equivalent is
used when silicone sealant is required and PTI 707 or equivalent is used when butyl
type sealant is required. Dow Corning 995 or equivalent structural silicone is used
where glazing sealant is required.
All sealant must be compatible with all surfaces on which adhesion is required,
including other sealant surfaces. All frame surfaces should be clean and dry. All
perimeter substrate shall be cleaned and properly treated to receive sealant.
5.) All materials are to be installed plumb, level, and true.
6.) Protect materials after erection. Cement, plaster, alkaline solutions, and acid based
materials can be harmful to the finish. Clean exposed finished surfaces with a mild
detergent and water. No abrasive cleaning agent should be used.

SECTION III-FABRICATION D - SILL WEEP NOTCHES
To evacuate water from the system, weep notches must be placed at
the ends of each sill. This notch will manifest itself as a 1/8" X 1" notch
at each end of the sill, joining the vertical at the exterior face of the sill.
The notch also must remove the two extended legs in the middle
portion of the sill. These legs must be removed at the same height as
the face notch and requires that more material be removed. This
material removal will not be seen because it is under the sill and is
covered by the subsill. Refer to figures 7 and 8 below for notching
layout.

SECTION IV - INTERIOR GASKET INSTALLATION
STEP 1) INTERIOR GASKET INSTALLATION
After all material is cut to the appropriate length, the WEQ1 interior
gasket/sealant backer should be installed. Begin the installation of the WEQ1
by first ensuring that the gasket race is clean and free of debris. The WEQ1
should be cut to the same length as the frame member it is being installed into.
Begin the installation on one end of the frame member and slide the WEQ1
into the raceway. It may be advantageous to use a light mixture of soapy
water to help the gasket slide into the race. After installation, ensure that the
WEQ1 is not stretched an excessive amount.
It is "possible" to install the WEQ1 after the frame members are assembled,
but it has to be pressed into the gasket race instead of sliding in. This is "far
more difficult and time consuming" and should be avoided unless absolutely
necessary. If the WEQ1 must be installed after the frame material is
assembled, a tool with a hooked tip of some type will ease the installation of
the gasket, as will a light mixture of soapy water. Refer to figure 9 below for
WEQ1 installation.
