Also known as louvered screens, mechanical equipment screens enhance facility longevity and aesthetics by concealing HVAC units and protecting expensive equipment from harsh weather. When made from aluminum, equipment screens offer superior durability. They resist rust and perform well in all conditions with minimal upkeep, unlike wood or steel.
While essential in commercial and industrial construction, these screens are often an afterthought. Integrating aluminum equipment screens during preconstruction is vital to prevent significant budget, schedule and design issues.
The Importance of Early Planning for Equipment Screens
Including equipment screens as part of the initial design process helps you avoid various issues:
Redesigns and Change Orders
Treating an equipment screen as a late-stage addition typically leads to costly redesigns, change orders and other administrative hurdles, inflating costs and interrupting workflows. With preconstruction planning, screen integration is a straightforward line item.
Lack of Structural Support
A significant physical challenge of last-minute additions is structural, as the building may not have been designed with aluminum equipment screen mounting requirements in mind. This typically results in expensive and complex retrofitting, as well as delays.
When planned early, the necessary structural support is integrated into the original design, and roof penetrations are incorporated from the outset. This helps prevent unnecessary complexities and costs while supporting timely project completion.
Compromised Building Envelopes
Rushing screen installation post-construction can compromise the building envelope. Issues such as drainage disruption, improper sealing and a lack of manufacturer approval risk voiding valuable roofing warranties.
During the planning and design phase, screen support posts are integrated into the roof plan before the installation of the membrane. As part of the installation, certified roofers can then correctly flash and seal these penetrations. This way, the posts are part of the roofing system and covered by warranty.
A Timeline for Team Coordination
Here’s a breakdown of the planning process by project phase, giving you a clear action plan:
1. Schematic Design
During this phase, establish the general location, approximate size and aesthetic goals for the screen to ensure alignment with the overall building design. Architects should develop detailed drawings and structural requirements, coordinating with mechanical equipment layouts to support integration.
For unique dimensions or tailored solutions, custom aluminum louvered screens offer design flexibility. For easy aluminum screen installation and cost-effectiveness, consider prefabricated units.
2. Design Development
Next, engineers define structural loads and attachment strategies. They must verify the building’s capacity to support the screen against wind and seismic forces. This stage involves designing connections to the primary structure, coordinating placement to avoid conflicts and ensuring the entire system is properly engineered to prevent issues like roof leaks or structural damage.
3. Construction Documents
This phase finalizes all details for a smooth construction process, including documentation of:
- Specific materials: Detail everything from the aluminum type and finish warranty to performance requirements like wind load ratings.
- Fastener types: Specify exact attachment methods, including types and sizes, as well as the spacing of anchors, bolts, and welds.
- Waterproofing interfaces: Document the integration of screen attachment points with roofing and flashing through step-by-step drawings, helping to achieve a watertight, manufacturer-approved seal.
Key Technical Integration Points
Effectively integrating aluminum equipment screens also requires precise technical coordination with other major building components. Understanding these requirements in the preconstruction stage is essential for efficient project execution and preventing costly complications.
Structural Support and Load Paths
One of the most critical aluminum equipment screen roof requirements is calculating design wind pressures and a clear load path from the screen to the building structure. You must carefully plan attachment methods with structural engineers to ensure integrity. Anchors, brackets and support systems must be compatible with the base structure.
