The provided documentation details aspects of the installation process for Milgard Tuscany windows, with a strong emphasis on proper flashing techniques, material compatibility, and corrosion resistance. The document, identified as an installation instruction manual, outlines procedures for ensuring a weather-tight and durable installation. It references several industry standards for materials and practices. The scope of the document focuses on the installation process itself, rather than window operation or maintenance post-installation, though post-installation checks are briefly mentioned.
Referenced Standards and Definitions
The installation instructions reference several standards to which adherence is expected. The document states that references to these standards should be to the edition indicated, and any undated reference should be interpreted as the latest edition of the code or standard. The document lists a reference to standards but does not provide specific standard numbers.
Several terms are defined within the document to ensure clarity during the installation process. A “sealant” is defined as a compound used to fill and seal joints or openings, contrasting it with a “sealer,” which is used on porous surfaces. Common sealant types include polysulfide rubber, silicone, acrylic latex, butyl rubber, and polyurethane. A “shim” is defined as a thin piece of material used to level or plumb a window frame during installation.
Flashing Procedures: Method A
The document details a specific flashing method, designated as Method A, which involves applying flashing over the face of the mounting flange. This method requires a strip of approved flashing material – either mechanically attached or self-adhered – to be applied in a weatherboard fashion around the entire perimeter of the window opening.
The procedure for Method A involves the following steps:
- Apply the first strip of flashing horizontally immediately below the sill.
- Cut the strip to extend past each side of the window.
- Ensure the strip projects even with the vertical jamb flashing to be applied later.
Sill Flashing Installation
Specific instructions are provided for installing sill flashing. The top edge of the sill flashing must be fastened or adhered to the framing. When mechanically attached, fasteners should be placed along the edge of the rough opening where they will be covered by the window’s mounting flange.
Crucially, the lower edge and the last 230 mm (9 inches) of each end of the sill flashing should not be fastened or adhered. This allows the water-resistive barrier, applied in a later step, to be slipped up and underneath the flashing in a weatherboard fashion. This detail is illustrated in Figure 2 of the referenced document, though the figure itself is not provided.
Post-Installation Procedures
Following the completion of the installation, several post-installation procedures are required. The installer must check the window for proper operation and locking mechanisms. Additionally, the documentation emphasizes the importance of covering flashing materials with exterior wall surfaces within a timeframe recommended by the flashing manufacturers.
Any damaged flashings or water-resistive barriers must be repaired before installing the exterior wall surface to maintain continuity between the barrier and the new materials. A minimum gap of 6 mm (1/4 inch) must be maintained.
Material Compatibility and Corrosion Resistance
The document stresses the importance of material compatibility. All materials that come into contact with each other – including coatings, flashings, and sealants – must exhibit chemical compatibility for their intended purpose. This is referenced to AAMA 713.
To prevent corrosion, metal products must be isolated from dissimilar or corrosive materials using a nonconductive coating or sealant. All fasteners used in the installation must be corrosion-resistant, adhering to standards such as ASTM B456, B633, or B766, as specified in AAMA TIRA9.
Scope and Referenced Documents
The document defines its scope as covering the installation process of Milgard Tuscany windows. It references other documents, stating that any undated reference to a code or standard should be interpreted as referring to the latest edition. The document begins with an introduction and outlines the sections covered, including scope, referenced documents, definitions, significance and use.
Conclusion
The provided documentation focuses on the critical aspects of a proper Milgard Tuscany window installation, emphasizing the importance of correct flashing techniques, material compatibility, and corrosion prevention. Adherence to the outlined procedures and referenced standards is crucial for ensuring a weather-tight, durable, and long-lasting installation. The document highlights the need for careful attention to detail, particularly regarding flashing installation and the use of compatible materials.
