Always look for certifications and test reports from trusted suppliers. This makes sure your ACP panels follow safety rules.
Non-combustible ACP Overview
What Is Non-combustible ACP?
You might ask how a non-combustible ACP is different. This type of panel does not catch fire or help fire spread. People use these panels in buildings where safety matters a lot. Building codes like IBC Section 703.4 have tough tests, such as ASTM E-136, to check if a panel is non-combustible. Vitraplate® is a famous product that passes this test. Since it is non-combustible, it does not need extra fire tests like NFPA 285 or ASTM E-84. Architects and builders trust it to keep people safe.
The core inside a non-combustible ACP is unique. It uses mineral or aluminum instead of plastic. These cores do not burn at all. They help the panel get high fire safety ratings like A2 or A1. Some panels have a 100% aluminum lattice core. This core is safe and also good for the planet because you can recycle it.
Tip: Picking non-combustible ACP helps protect your building and everyone inside from fire.
Key Features
Non-combustible ACP is special because it is very safe and works well. The main differences are easy to see in the table below:
Property Type | Non-Combustible ACPs (Fire-Retardant) | Other ACPs (Standard) |
|---|---|---|
Core Material | Fire-retardant substances such as mineral-filled or honeycomb cores | Combustible polyethylene or polyurethane cores |
Fire Resistance | High fire resistance due to FR core materials, compliant with building regulations | Lower fire resistance, core materials are combustible |
Surface Coating | High-quality coatings like fluorocarbon, polyester, PVDF, or nano coatings providing durability, fire resistance, and water repellency | PE coating mainly for interior use, less fire resistant |
Physical Properties | Lightweight, durable, flexible, chemical and water resistant, sound insulating | Lightweight and flexible but less fire resistant and potentially less durable |
Thickness Range | Typically 3 to 6 mm, often >4 mm for cladding, varies with core material | Similar thickness range but core affects overall properties |
You can see that non-combustible ACP uses mineral or aluminum cores. Standard panels often use polyethylene, which burns easily. The special core and coatings give non-combustible ACP high fire resistance. This makes it safer for tall or important buildings.
Here is a chart that shows how different core types do in fire resistance tests:
Non-combustible ACP panels stop fire from spreading and last a long time. They resist water, chemicals, and weather. You can use them for many years without worry. Aluminum composite panels with mineral or aluminum cores meet the strictest building codes. This means your project will pass inspections.
Aluminum Composite Panel Types
Traditional vs. Non-combustible
There are big differences between traditional and non-combustible aluminum composite panels. Traditional panels have two thin aluminum sheets. They use a polyethylene (PE) plastic core. The PE core can burn fast and spread fire. These panels do not pass strict fire safety rules for many buildings.
Non-combustible panels are made in a safer way. Some use solid aluminum sheets that do not burn. Others have special cores made from minerals or metals. These panels get top fire safety ratings like A1 or A2. You can trust them for projects where safety matters most.
Traditional ACPs have a PE core that burns and raises fire risk.
Non-combustible ACPs use A2 or A1 cores for better fire safety.
Solid aluminum sheets do not burn and give the best protection.
Pick the right panel based on safety, strength, and design needs.
Note: Not all aluminum composite panels are alike. Always check the core type before picking a panel for your building.
Fire-retardant ACP Cores
Fire-retardant acp cores help keep buildings safe. These cores use minerals like alumina trihydrate (ATH) or magnesium hydroxide (MDH) mixed with a polymer. This mix slows flames and lowers heat in a fire. You see these panels in hospitals, schools, and tall buildings. They help meet tough fire codes like NFPA 285 and ASTM E84.
Fire-retardant acp panels slow flames and keep heat low.
Big tests show fire-retardant acp panels keep flames under 10 feet and heat below 1 MW.
Standard PE core panels let flames reach over 25 feet and heat above 6 MW.
Fire-retardant acp panels are needed for tall buildings and busy places.
But fire-retardant acp cores have some limits. They have about 70% mineral fillers and 30% polymers that can burn. So, they do not give as much fire safety as fully non-combustible cores. Those have more than 90% minerals and almost no polymers. Always check the fire rating and core type to make sure your panel is safe for your project.
Fire Safety Benefits
Reduced Fire Spread
You want your building to stay safe if a fire starts. Non-combustible aluminum composite panels (ACPs) help stop flames from moving quickly. The secret is in the core. When you choose panels with an a2 mineral-filled core or B1 grade, you get better fire resistance. These mineral-filled cores do not burn or make smoke. They slow down the reaction-to-fire and keep toxic fumes away.
Mineral-filled cores in A2 and B1 panels limit fire spread and lower smoke.
A2 panels use about 90% minerals and only 10% recycled plastic, so they resist flames and do not release harmful gases.
The core sits between two aluminum sheets, making the whole panel strong and fireproof.
If you use panels with a plastic core, fire can move up the wall fast. Combustible materials like EPS foam catch fire at low temperatures and release a lot of heat. This makes flames spread quickly, especially in tall buildings. Non-combustible ACPs, tested under NFPA 285 and ASTM E119, show much less flame spread. You protect people and property by choosing panels that slow down fire.
Tip: Always check the core type before you buy ACPs. Mineral-filled cores give you better fire resistance and help keep your building safe.
Compliance with Standards
You need to follow strict rules to keep your building safe. Fire safety standards test how materials react to fire and how much they help flames spread. The most important standards for ACPs are EN13501-1, NFPA 285, and ASTM E136.
Standard | What It Tests | Why It Matters for ACPs |
|---|---|---|
EN13501-1 | Reaction-to-fire, smoke, droplets | Classifies panels from E to A1 for fire resistance |
NFPA 285 | Flame spread in wall assemblies | Checks vertical and horizontal fire movement |
ASTM E136 | Material combustibility | Proves if the core is non-combustible |
EN13501-1 gives you a reaction-to-fire rating. A2 panels meet A2-s1, d0, which means they do not help fire spread, make little smoke, and do not drip flaming particles. NFPA 285 tests the whole wall, not just the panel. It looks at how fire moves up and across the wall. ASTM E136 checks if the core burns at high heat. If your ACP passes these tests, you know it has strong fire resistance.
Non-combustible ACPs meet these standards by using mineral-filled cores and aluminum layers. The panels do not ignite or help fire move. Manufacturers test their products and get certifications to prove they meet fire safety rules. You should always ask for these documents before you buy. Good suppliers will show you proof that their panels passed reaction-to-fire tests and meet local codes.
Non-combustible ACPs use mineral cores to pass EN13501-1 and ASTM E136.
Panels must pass NFPA 285 to be used in curtain walls.
Certifications and test reports show you the panel’s fire resistance.
Note: You keep your building safe and follow the law when you choose ACPs that meet fire safety standards.
ACP Cladding in Curtain Walls
Application Methods
There are different ways to put acp cladding on curtain walls. Each way has its own good points for your building’s outside look. The table below lists the main ways to install panels and what makes each one useful:
Installation Method | Description | Key Advantages |
|---|---|---|
Wet Sealant Joint | Panels are set on a frame. Sealant is put in the joints to keep water out. | Stops water, works for new and old buildings. |
Hanging Method | Panels hang from the frame. They are not tight, so they can move a little. | Easy to put up, lets panels move with heat or cold. |
Dry Gasket Joint | EPDM gaskets fill the joints. This makes the panels last longer and stay clean. | Lasts long, keeps dirt off the panels. |
Narrow Open Joint | Panels have small gaps between them. Sealants and fasteners hold them in place. | Looks modern, seals well. |
Pick the way that fits your project best. Wet sealant joints are good for stopping water. Hanging methods are best if you need the panels to move. Dry gasket joints help keep the panels clean and strong. Narrow open joints make your building look modern.
