Introduction
Aluminium Composite Panels (ACPs) offer modern aesthetics, weather resistance, and versatility — but to unlock their full potential, proper installation is key.
Whether you’re a contractor, builder, or project manager, this guide walks you through how to install aluminium composite panels, the tools you’ll need, and the mistakes to avoid that could compromise performance and appearance.
Tools Required for ACP Installation
Before you begin, make sure you have the right tools on site:
- Measuring tape
- Spirit level or laser level
- Jigsaw or circular saw (with fine-tooth blade)
- Hand drill and appropriate drill bits
- Rivet gun or screw gun
- Clamps and straight edges
- Silicone sealant and sealant gun
- Safety gear (gloves, goggles, dust mask)
Optional but useful:
- CNC routers (for precision cutting in large-scale jobs)
- Panel lifters or suction handles (for large panels)
Step-by-Step Guide: How to Install Aluminium Composite Panels
- Site Preparation
- Ensure the wall surface is clean, dry, and flat.
- Mark guidelines on the structure using a laser level or chalk lines.
- Subframe Installation
- ACPs are typically mounted on a metal subframe (usually aluminum or galvanized steel).
- Ensure proper spacing between vertical and horizontal support members.
- Fix the frame securely to the main wall using appropriate anchors.
- Cutting Panels to Size
- Use a circular saw or jigsaw to cut panels based on your measurements.
- Wear protective equipment and ensure edges are clean and burr-free.
- Always leave a small expansion gap (typically 3–5 mm) between panels.
- Panel Fixing
There are two main methods:
Visible Fixing (Mechanical):
- Panels are fixed using screws or rivets through the face.
- Use color-matched caps to maintain aesthetics.
Concealed Fixing (Cassette System):
- The panel edges are folded to create a cassette that is clipped or hung onto a system.
- Offers a cleaner, screw-free look, ideal for high-end façades.
- Sealing and Finishing
- Use silicone or polyurethane sealant between joints for waterproofing.
- Apply protective trim profiles if needed.
- Remove protective films only after installation is complete.
Common Mistakes to Avoid
- Skipping the Expansion Gap
Aluminium expands and contracts with temperature changes. Failing to leave space between panels can cause buckling or warping.
- Improper Support Structure
An uneven or loosely fixed subframe can lead to panel misalignment, poor weatherproofing, and vibration noises.
- Overtightening Screws or Rivets
This can deform the panel surface or lead to cracking around fasteners. Always use washers and maintain moderate torque.
- Cutting Without Proper Tools
Using inappropriate blades can chip or melt the core, damaging the panel edge and compromising appearance.
- Delaying Film Removal
Leaving protective films on too long (especially under the sun) can make them difficult to peel and leave adhesive marks.
Expert Tips for a Professional Finish
- Always pre-drill holes to avoid cracking or distortion
- Seal all open edges with edge tape or profiles to prevent water ingress
- For large façades, start from the bottom and work upwards
- Conduct a dry layout test before final fixing to avoid misalignments
Final Thoughts
ACP installation isn’t just about fixing panels — it’s about ensuring safety, aesthetics, and long-term performance. With the right tools, preparation, and awareness of common pitfalls, you can achieve a clean, modern, and durable finish for any project.
