The provided documentation details JELD-WEN’s recommended installation procedures for vinyl windows featuring an integral nailing fin. The instructions emphasize the importance of integrating the window with the building’s weather barrier, typically building wrap, to maintain airtightness and prevent water intrusion. Installation can also adhere to AAMA specifications (2400-02) without affecting the JELD-WEN limited warranty. The documentation stresses adherence to local building codes, which supersede JELD-WEN’s recommendations, and highlights specific considerations for high-elevation installations and non-standard wall conditions.
Integrating with the Weather Barrier
JELD-WEN installation methods focus on integrating the window directly with the structure’s weather barrier. This approach addresses the increasing airtightness of modern buildings, which can create negative air pressure and draw moisture through even small openings. The recommended practice involves applying a non-water-degradable, thin sheet material – such as vinyl sheeting – as backing support around the rough opening before applying the building wrap. This backing support should completely surround the opening and be flush with the exterior trim when the window is installed. The window’s nailing fin is then secured against this backing support.
AAMA Specification Compliance
While JELD-WEN provides specific installation instructions, installers have the option to follow the American Architectural Manufacturers Association (AAMA) specification 2400-02. The documentation explicitly states that adherence to AAMA 2400-02 will not void the JELD-WEN limited warranty. This provides flexibility for installers familiar with and certified in AAMA installation practices.
Local Building Codes and Regulations
The documentation repeatedly emphasizes the importance of complying with local building codes and regulations. It states that these local requirements take precedence over JELD-WEN’s recommended installation instructions. Installers are responsible for consulting with local building code officials to ensure that the installation meets all applicable standards. This is particularly crucial given the variability of building codes across different jurisdictions within the United States.
Backing Support Requirements
Proper backing support is critical for a successful and warrantable installation. The documentation specifies that the backing support material must be non-water-degradable and have a maximum thickness of 1/8 inch. This support is applied to the wall framing before the building wrap is installed. The purpose of the backing support is to provide a stable surface for the window’s nailing fin to be secured against, ensuring a tight and weather-resistant seal. The documentation illustrates the placement of backing support in relation to trimmer studs, headers, sheathing, and king studs.
High-Elevation and Specialized Installations
The documentation includes a specific cautionary note regarding installations where the window sill is located more than 35 feet above ground level. In such cases, the installation must be designed by a qualified architect or structural engineer. Similarly, any installation into a wall condition not specifically addressed in the JELD-WEN installation instructions requires professional design by an architect or structural engineer. This highlights the importance of considering structural loads and environmental factors in challenging installation scenarios.
Ensuring Square, Level, and Plumb Openings
The documentation warns that failure to install windows into square, level, and plumb openings could result in denial of warranty claims for operational or performance problems. This underscores the need for precise measurements and careful installation techniques. Achieving a properly aligned opening is fundamental to the window’s long-term functionality and weather resistance.
Documentation and Responsibility
JELD-WEN instructs installers to provide a copy of the installation instructions to the building owner. This ensures that the owner is aware of the installation procedures and the terms and conditions of the limited product warranty. By installing the product, the installer acknowledges acceptance of these warranty terms.
Product Range Coverage
The provided documentation references installation instructions for vinyl windows with an integral nailing fin. Additional documentation notes the availability of instructions for interior and exterior doors, wood and clad-wood windows, and wood and clad-wood patio doors. The documentation suggests that users can search for specific model instructions on the JELD-WEN website or contact customer support for assistance.
Conclusion
JELD-WEN vinyl window installation requires careful attention to detail, particularly regarding integration with the weather barrier, adherence to local building codes, and proper backing support. The documentation provides clear guidance on these aspects, emphasizing the importance of professional design for high-elevation or non-standard installations. Maintaining square, level, and plumb openings is crucial for ensuring long-term performance and preserving warranty coverage. Providing the installation instructions to the building owner is a final step in ensuring a successful installation and informed ownership experience.
