Series 433 Triple Set Installation Instructions
SECTION I: General Notes
The “433 TRIPLE SET” is a framing system that has many advantages over other framing
systems. It can be used as a single-span storefront window wall, a punched opening
system, or as a ribbon window system. The main advantage is the ability to set the glass
plane in three different positions within the same elevation.
The 433 Triple Set system contains primarily stock length systems with in-the-field
fabrication. Entrance doors are also a designed part of these systems, utilizing frames
that can accommodate many types of doors and hardware combinations.
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 benchmarks and/or column centerlines 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. 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 sealants must meet ASTM C 920, CLASS 50.
When required Butyl sealant – A non-skinning, non-hardening material (NAAMM
Reference Standard 5C-1)
NOTE: All sealant must by compatible with all surfaces where 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.
