ACP Cladding for Shop Fronts: Grades, Fire Safety and Upkeep

For a shop front in Gurgaon or Noida, specify FR (fire-retardant) core ACP, usually 4 mm thick with a proper aluminium skin, a durable coating for outdoor colour, fixed on a rust-protected sub-frame with sealed joints, and plan the signage and wiring before the panels go up. That combination looks sharp on opening day and still looks right years later. Cheaper panels mostly save money on exactly those points.

ACP cladding (aluminium composite panel) is the default shop front and elevation finish in markets across Gurugram, from Sohna Road and MG Road to Sector 18, Noida. This guide explains what is inside the panel and what to ask for.

What is ACP made of?

An ACP is a sandwich: two thin aluminium skins bonded to a core. The outer skin carries the coloured coating; the core gives the panel its thickness and flatness. Three things decide quality: the core, the skin thickness and the coating.

FR core or PE core: why does it matter?

PE (polyethylene) core ACP has a plain plastic core. It is cheaper and easy to work, but the core burns. FR (fire-retardant) core ACP has a core that is largely mineral-filled, so it resists fire spread much better. Some manufacturers also offer higher, non-combustible-class cores.

After facade fires abroad, many building codes and building managements have tightened rules on combustible cladding. In India, many malls, commercial complexes and larger buildings now ask for FR-grade panels on their facades. Check with your building management and the building's terms, and ask your supplier for the manufacturer's test certificate for the panel actually being supplied.

What thickness of ACP should a shop front use?

ACP is commonly sold in 3 mm and 4 mm panel thicknesses. 4 mm is the usual choice for exteriors: it stays flatter over larger panels and resists dents better. 3 mm is common for interiors and signage boards.

The aluminium skin thickness matters even more than the total thickness. Exterior-grade panels commonly use skins around 0.5 mm; cheaper panels use much thinner skins that dent, ripple in the sun and show the frame through the face. Ask what skin thickness is being quoted.

Coating: PVDF or polyester?

Outdoor ACP usually comes with a PVDF (Kynar-type) coating, which holds its colour and gloss well in strong sun. Polyester coatings are cheaper and fine indoors but can fade and chalk faster outside. A west-facing shop front on a Gurgaon market road gets serious afternoon sun, so the coating matters.

How should ACP be fixed to the building?

ACP is never fixed straight onto plaster. It goes on a sub-frame, usually aluminium or MS tube, anchored into the wall or slab. The frame keeps the panels flat, creates a ventilated gap behind them, and carries wind load.

An MS sub-frame must be primed and painted, because rust behind the panel shows later as stains and loose fixings. Most cases of an ACP panel coming loose trace back to a weak frame, too few fixings, or sealant that has failed.

How do you fit signage into an ACP front?

Signage is usually the reason for the ACP, so plan it into the design rather than drilling into finished panels later:

1. Fix the sign size, position and type first: flat cut letters, 3D acrylic letters, or backlit letters with LEDs.
2. Run conduits and power points behind the cladding before the panels close, with access for the LED drivers.
3. Add backing members in the frame where heavy letters or a projecting sign will be fixed.
4. For backlit cut-out letters, the ACP is routed and acrylic fitted behind, which needs a box behind the panel.
5. Check market association, mall or building rules on sign size and lighting before you finalise.

What sits well with ACP on a shop front?

ACP rarely stands alone. Most fronts combine it with a toughened glass shop front with a door for the display, a rolling shutter for security after hours, and sometimes aluminium louvres to hide AC units. Bigger showrooms and offices in areas like Udyog Vihar may use structural glazing for a full glass facade with ACP bands. Planning these together makes the joints line up and avoids repeated scaffolding.

How do you keep an ACP front looking new?

• Peel the protective film promptly after installation. Film left on in the sun bakes onto the panel and becomes very hard to remove.
• Wash the panels a few times a year with water and a mild detergent and a soft cloth; avoid abrasive pads and harsh solvents.
• Check the joint sealant once a year, especially after the monsoon, and redo any cracked or shrinking joints.
• Look for rippled or lifting panels; act early, before a loose panel catches the wind.
• Keep the sign's electrical box accessible and dry.

Can ACP go over an old shop front?

Often, yes, and it is one of the main reasons shopkeepers in older markets choose it. ACP on a sub-frame can cover tired plaster, old tiles or a stained stone front without breaking them out, as long as the wall underneath is sound enough to anchor the frame. A few checks come first:

• Loose plaster or tiles behind the frame line are removed, so the anchors go into solid masonry or concrete.
• Any dampness in the wall is dealt with; cladding over a wet wall hides the problem rather than solving it.
• Old signboards, brackets and wiring are taken down or rerouted before the frame goes up.
• Shutter boxes, AC drain pipes and meter boards are planned around, so they stay reachable.

What changes the price of ACP cladding?

ACP is priced per sq ft. Panel brand and core (FR vs PE), panel and skin thickness, coating, the sub-frame, the fixing system, signage cut-outs, height and scaffolding all move the figure, and so does whether the old front must be removed.
