Section 1. General Notes
HANDLING / STORING / PROTECTING ALUMINUM
The following guidelines are recommended to ensure 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 immediately removed with
soap and water. Under no circumstances should these materials be allowed to dry or permanent staining may
occur.
GENERAL GUIDELINES
The following practices are recommended for all installations
A. REVIEW CONTRACT DOCUMENTS – Become thoroughly familiar with the project. Check shop drawings,
installation instructions, architectural drawings and shipping lists. The shop drawings take precedence and include
specific details for the project. Shop drawings govern when conflicting information exists in the assembly and
installation instructions. Note any field verified notes on the shop drawings prior to installing. EFCO assembly and
installation instructions are general in nature and cover only some of the conditions.
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.
D. PERIMETER CONDITIONS - Verify that all job site conditions and accompanying substrates receiving the
installation 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 area in
question.
E. ISOLATION OF ALUMINUM - Prevent all aluminum from coming in direct contact with masonry or dissimilar
materials by means of an appropriate primer. Typical slab anchors may be set directly onto concrete surfaces in a
block-out pocket at the edge of the slab. The block-out pocket is later filled in with grout thereby covering the slab
anchor. In such cases, a heavy coat of zinc chromate or bituminous paint must be pre-applied to the slab anchor.
F. SHIPMENT VERIFICATION - 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.
G. SEALANT - All sealant must meet [ASTM C 920, CLASS 50]. 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 min.) air and water seal between similar and dissimilar materials.
All sealant must be compatible with all surfaces on which adhesion is required, 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. All sealants and primers must be
applied according to the sealant manufacturers instructions and recommendations. It is the responsibility of the
glazing contractor to submit a statement from the sealant manufacturer indicating that glass and glazing materials
have been tested for compatibility and adhesion with glazing sealants, and interpreting test results relative to
material performance, including recommendations for primers and substrate preparation required to obtain adhesion.
The chemical compatibility of all glazing materials and framing sealants with each other and with like materials used
in glass fabrication must be established.
