Sandwich Panel Installation

Sandwich Panel Installation

Sandwich Panel Installation

Sandwich Panels are widely used for roofing, wall cladding, and cold storage insulation in industrial, commercial, and residential buildings. They consist of two outer metal sheets (steel/aluminum) with an insulated core (PUF, EPS, or Rockwool) for thermal and sound insulation.

Tools & Materials Required

✔ Sandwich Panels (Roof/Wall Type)
✔ Self-Drilling Screws with EPDM Washers
✔ Metal Cutter / Circular Saw
✔ Silicone Sealant
✔ Measuring Tape & Markers
✔ Power Drill & Screwdriver
✔ Lifting Equipment (Cranes, Suction Cups, etc.)
✔ Protective Gear (Gloves, Helmet, Safety Glasses)

Installation Steps
Preparation & Site Inspection

  • Ensure the structure (steel frame/concrete wall) is level and ready.
  • Plan panel layout and direction to minimize waste.
  • Check for proper anchoring points and load-bearing capacity.

Panel Positioning & Lifting

  • Use lifting equipment (crane or manual suction lifters) to place the panel gently on the structure.
  • Leave a 2-3mm expansion gap between panels to prevent thermal stress.

Fixing & Fastening

For Roofing Panels:

✔ Overlap panels by 1 corrugation for waterproofing.
✔ Fix screws at high ribs of the panel, every 300-500mm.

For Wall Panels:

✔ Install panels vertically or horizontally, ensuring proper joint alignment.
✔ Use self-drilling screws and PUF-compatible sealant between joints.

Sealing & Waterproofing

  • Apply silicone sealant along all joints and fasteners.
  • Use flashing & ridge caps for roofing to prevent water leakage.
  • Ensure proper drainage slopes for roof panels.

Final Inspection & Finishing

  • Check for loose screws, gaps, and panel alignment.
  • Clean the surface and remove protective film.
  • Conduct a water leakage test if necessary.

Key Considerations for Proper Installation

✔ Avoid Over-tightening Screws – It may damage panel surfaces.
✔ Handle Panels Carefully – Avoid denting or scratching surfaces.
✔ Store Panels Properly – Keep them dry and covered before installation.
✔ Use Compatible Sealants – Prevents chemical damage to insulation cores.
