Double-Lok over R

Product catalog summary

General Information: The document provides technical installation guidelines for the Double-Lok® roofing system over an existing "R" panel. It stresses the importance of thoroughly reading the manual before installation and inspecting all materials. In case of discrepancies between project drawings and the manual, the project drawings take precedence.

Design Information: The Double-Lok® roof can be installed over an existing "R" panel with minimal modifications. It allows for venting or additional insulation between the old and new roofs. The installation adds approximately 1.5 lbs per square foot to the existing structure, and a professional engineer should verify the structure's capacity to support this load. Compliance with current building codes is essential, which may require adjustments in purlin spacing.

Product Checklist: The checklist includes components such as Double-Lok® panels, clips, closures, and sealants, specifying dimensions, materials, and intended use to ensure proper installation and compatibility with the existing structure.

Installation Procedures: Detailed instructions are provided for retrofitting the Double-Lok® system, including clip attachment and venting options. The manual outlines specific scenarios such as edge zones, vented roof cavities, and insulated roof cavities, with corresponding installation techniques.

Recommendations: The document advises consulting with a registered professional engineer for load assessments and ensuring all installations comply with the latest building codes. It also suggests surveying the existing roof to determine the need for narrower panels if the existing roof is out of module.

Overview: This document provides technical guidelines for the installation of MBCI's Double-Lok® roof system over existing 'R' panel roofs, including cautions, preparatory requirements, and design specifications.

Cautions: The Double-Lok® roof system does not provide diaphragm capabilities or purlin stability, necessitating additional bracing. The minimum recommended roof slope is 1/4 on 12 to prevent ponding and maintain material warranties. Design details are illustrative and must be adapted to specific environmental conditions and building codes. Installation must comply with OSHA regulations, and deviations from the manual require MBCI's written approval.

Preparatory Requirements: Preparations include cutting back the eave of the existing 'R' panel roof, installing a retrofit eave angle, and ensuring the existing roof is on plane within specified tolerances. Field cutting of panels should be avoided; if necessary, use nibblers, snips, or shears. Adjust trim conditions if different wall panels or conditions exist.

Design Specifications: Details for edge zone conditions and clip spacing must be determined by a professional engineer. Various fasteners and components are specified for different parts of the installation, including self-drillers and long-life screws with washers. Illustrations provide isometric views of edge zone conditions, vented roof cavities, and insulated roof cavities.

Key Components: Retrofit eave angle, rake angle, and support angles are critical for installation. Fasteners are specified by type and location, ensuring secure attachment of panels and components. Sealers and closures are used to ensure weather-tightness and insulation.
