Installing insulated roof panels isn’t just about fixing them in place—it’s about ensuring thermal efficiency, structural strength, and long-term durability. At ALP Industries, we follow a precise installation process for our PUF/PIR/Glass Wool/Rock Wool-based roof panels, engineered to deliver maximum performance from day one.
Whether you’re planning a warehouse, cold room, or industrial shed, here’s a clear look at how ALP Roof Panels are installed for best results.
Step 1: Site Preparation & Measurement
Before installation, our technical team:
- Conducts a site inspection
- Measures the purlin spacing and structural layout
- Confirms load-bearing capacity
- Prepares panel layout drawings
Why this matters: Proper alignment and layout minimize cutting, waste, and installation errors.
Step 2: Panel Handling & Storage
ALP Roof Panels are delivered in protective packaging. On-site:
- Panels are stored horizontally on flat, dry ground
- Handled using lifting belts or soft slings to prevent surface damage
- Stored in a shaded area to protect the insulation core from prolonged UV exposure
Pro tip: Improper stacking or dragging panels can damage the joints and reduce sealing efficiency.
Step 2: Panel Handling & Storage
Ensure the steel or concrete structure (purlins/trusses/beams) is:
- Aligned, clean, and free from rust or debris
- Coated for corrosion resistance (if needed)
- Anchored firmly for wind and load resistance
We also confirm support intervals match the panel thickness for maximum stability.
Step 4: Panel Placement & Alignment
- Panels are lifted one-by-one onto the roof
- The first panel is carefully aligned, as it sets the baseline for the rest
- The corrugated top side faces upward, and the smooth liner faces the inside
Accuracy here ensures proper jointing and aesthetic consistency across the roof.
Step 5: Fixing & Fastening
- Self-drilling screws are placed every 300–500 mm, depending on wind load and span
- Screws are inserted within the V-cut groove, allowing for concealed fixing
- Double screws at 30 mm spacing are used for structural integrity
- Washers and sealing gaskets ensure watertight performance
Key Advantage: ALP’s blind fastening system ensures a clean exterior with no exposed fixings.
Step 6: Joint Sealing & Insulation Continuity
- Double labyrinth joints between panels ensure an airtight seal
- For cold storage or high-humidity zones, PU sealants or butyl tape are applied to joints
- Overlaps and junctions are sealed to eliminate thermal bridging and air leakage
Result: Long-lasting insulation with no thermal loss or water ingress.
Step 7: Trims, Flashings & Finishing
- Flashings are installed at edges, ridges, and junctions
- Gutters, cappings, and bargeboards are fixed
- All penetrations (like skylights or vents) are sealed
Final cleaning is done to ensure a polished look and debris-free surface.
The Result: A Roof That Works Smarter
When installed correctly, ALP Roof Panels offer:
- Excellent thermal insulation (up to 40% HVAC savings)
- Fast construction timeline
- Enhanced strength and load-bearing capacity
- Superior resistance to moisture, weather, and corrosion
- Aesthetically clean finish with no visible screws
