PP Honeycomb Protection Board for Cleanroom Installation: Low-Shedding Floor Protection

Cleanroom installation adds particle control to every decision: materials brought in must not shed, must be cleanable and must not compromise the room’s classification. This article looks at protecting cleanroom floors during installation and qualification. The focus is low-shedding materials, cleaning compatibility and protecting a controlled surface.

Particle control governs the material choice

In a classified space, the first test for any temporary material is whether it sheds particles and whether it can be cleaned to the room’s standard. That eliminates paper, cardboard and most timber products immediately.

A PP honeycomb protection board is a non-shedding plastic panel that can be wiped with compatible agents, which is why it can be considered where other protection cannot.

Confirm the material with the validation or QA team before it enters the room, because approval is part of the qualification record.

Thickness choices from 2 mm to 12 mm

Cleanroom installation involves equipment moves and trolleys, so the middle to upper part of the 2 mm to 12 mm range is usual for routes.

For pedestrian access during installation a mid thickness is enough. Where equipment and vessels are moved into the room, thicker boards spread the loads that would otherwise damage the floor covering and its sealed joints.

Cleaning, seams and preserving classification

Finish seams and edges so they do not collect particles, and clean panels on the room’s schedule rather than treating them as an exception.

Wipe panels before they enter the room and inspect them when lifted, because contamination introduced during works is expensive to remove later.

Keep protection clear of returns, grilles and any airflow path, since covering them changes the room’s behaviour as well as its cleanliness.

How honeycomb board compares with film, ply and matting

Cleanroom films are designed for this and are often the first choice for flat surfaces, but they are single-use and do not protect against point loads.

Plywood sheds, absorbs cleaning agents and is generally excluded from classified areas. Matting is cleanable but heavy and usually permanent rather than temporary.

A PP honeycomb board is non-shedding, cleanable and reusable, and it adds the load spreading that film cannot provide during equipment installation.

A practical trial plan for cleanrooms

Get QA approval for the material first, then protect one route and keep a comparable route on the current method. Inspect on the room’s cleaning schedule.

Run a cleaning test with the approved agent and check for residue and particle generation.

Record the approval, the cleaning log and the condition at lift, because those records support requalification.

What to include in a protection board enquiry

State the room classification, the floor covering, the cleaning agents, the equipment loads and the fire performance required. Ask for confirmation that the board is non-shedding and cleanable.

Ask for documentation to support material approval, and about custom sizes to reduce cutting inside the room.

Final takeaway

In a cleanroom, get material approval first, keep airflow paths clear, finish seams against particle traps and specify thickness for equipment loads.
