PUF Panel Installation Accessories: Complete Guide to Essential Components

Why Installation Accessories Matter

Here's something most contractors won't tell you upfront: even the best PUF panels will underperform if installed with substandard accessories. I've seen cold storage projects lose 15-20% thermal efficiency simply because someone decided to save a few thousand rupees on sealants and fasteners.

After working on hundreds of installations across Gujarat and Maharashtra, I can say with certainty that accessories account for only 8-12% of your total material cost but influence 40% of your installation's long-term performance. Let's break down exactly what you need.

Essential Fastening Systems

The way you secure panels determines everything from structural integrity to thermal bridging.

Self-Drilling Screws

For roofing panels, you'll need stainless steel self-drilling screws with EPDM washers. Standard specs:

• Length: Panel thickness + 25mm minimum penetration into purlin
• Diameter: 5.5mm for panels up to 80mm; 6.3mm for thicker panels
• Washer: 19mm EPDM bonded washer (UV-stabilized for roofs)
• Coating: Zinc-aluminum or stainless steel for corrosive environments

Cam Lock Systems

For cold storage and cleanroom applications, cam locks provide tool-free assembly with superior airtightness. These concealed fasteners create flush surfaces essential for hygiene-critical environments.

Sealants and Gaskets

This is where most budget-conscious projects go wrong. A proper sealing system includes:

Primary Sealants

• Polyurethane sealant: For joint sealing between panels (remains flexible at -40°C to +80°C)
• Silicone sealant: For perimeter sealing and penetrations
• Butyl tape: Pre-applied to panel joints for immediate weather protection

Gaskets and Strips

• Foam closure strips: For ridge and eave closures on roof panels
• EPDM gaskets: For door frames and window openings
• Thermal break strips: Between panels and steel structure to prevent condensation

Flashings and Trim

Flashings aren't just aesthetic—they're your first line of defense against water ingress.

Standard Flashing Types

Flashing Type	Location	Recommended Gauge
Ridge Flashing	Roof apex	0.5mm PPGL
Gutter Flashing	Eave line	0.6mm PPGL
Corner Flashing	External corners	0.5mm PPGL
Base Flashing	Wall-floor junction	0.5mm SS304 (wet areas)
Parapet Coping	Parapet walls	0.6mm PPGL

Specialized Accessories for Cold Storage

If you're building a cold storage facility, standard accessories won't cut it. You need:

• Heated door frames: Prevent ice buildup around cold room doors
• Vapor barriers: PE film or aluminum foil facing on warm side
• Floor heating cables: Prevent frost heave in freezer rooms
• Pressure relief valves: Equalize pressure during defrost cycles
• Strip curtains: Minimize cold air loss at doorways

Cleanroom-Specific Components

For cleanroom installations, every detail affects particle control:

• Flush-mount light fixtures: Sealed LED panels that sit within ceiling grid
• HEPA filter housings: Integrated into ceiling system
• Coving profiles: Radius corners for wall-floor junctions
• Pass-through boxes: Material transfer without contamination
• Viewing windows: Double-glazed, flush-mounted observation panels
