Choosing Depth by Room Function

Depth follows the room's hygiene class and its temperature, in that order:

Room or zone	Depth	Reason
Corridors, changing rooms, airlocks	50-75 mm	Cheapest way to divide space without a wet trade
General production areas	75-100 mm	Flush face wipes down; no ledges where soil collects
Wash-down bays, high-care zones	100 mm	Sealed joints survive daily pressure washing
Chill rooms held near plus 4 degrees	150 mm	Holds the band while the doors cycle all shift
Freezer rooms at minus 20 degrees	200 mm	No interstitial condensation at the cold face

Product Data

Parameter	Typical value
Product	Polyurethane Foam PUF Panels
Skin	Galvanised and pre-painted coil (PPGI or PPGL), hot-dip zinc sheet, or aluminium where chemicals are used
Insulant	Closed-cell rigid PU foam at high density
Panel thickness	50-200 mm; 30 mm for internal linings
Skin thickness	0.3-0.8 mm
Width	960 mm or 1,000 mm
Panel length	Cut to the room height, maximum 11.8 m
Core density	38-43 kg per cubic metre
Lambda	0.022-0.024 W per metre-kelvin
Water uptake	Maximum 1.5%
Fire rating	B1, self-extinguishing. Polyurethane does not reach A1 - where a non-combustible core is required, ask for the rock wool variant
Brand	QY
Manufactured in	Liaoning, China

Depth Selection

Partitions carrying no thermal duty use 50 mm; production areas and wash-down bays normally take 75-100 mm; chill and freezer rooms take 150-200 mm. The core is rigid polyurethane throughout - EPS is not substituted in this product.

Surface Material & Coating Facings

Option	Where it fits
Pre-painted galvanised or galvalume coil	The default choice; smooth, wipe-clean and chemically resistant
Hot-dip zinc-coated sheet	Where humidity or cleaning agents are aggressive
Aluminium sheet	For salt-laden air, or where weight governs
Coating	Resists UV, cleaning chemicals and repeated wash-down

Colour and Surface

White, light grey, sky blue and terracotta are stocked, and white dominates hygienic areas because it shows soil straight away and reads as clean. Any RAL reference can be matched, and satin or gloss can be specified to change how readily the surface releases dirt.

Where It Is Used

Area	Requirement met
Food and drink production	Wash-down walls in high-care and high-risk zones
Pharmaceutical and healthcare	Smooth coved junctions that can be disinfected
Electronics and precision assembly	Dust-tight partitions with joints that seal
Commercial kitchens and canteens	Grease-resistant face that survives daily cleaning
Laboratories and research rooms	Chemical-resistant surface that sheds no fibres

Recent Installation

A dairy processing plant in Johor, Malaysia, lined 5,200 m2 of its high-care and packing halls with 100 mm board in 2022. The rooms are pressure-washed twice a day and audited under a GMP regime, so joint detail and surface finish governed the choice over price. Panels arrived cut to ceiling height with coved skirtings and sealed penetrations, and the plant passed its hygiene audit at the first visit after handover.

Made to the Room Schedule

Every order is cut to the room: panel lengths follow ceiling height, openings for doors, ductwork and pipe sleeves are pre-formed, and coved skirtings and corner pieces are supplied to match. One contact handles the schedule from enquiry to handover, and sample panels in the specified finish go out before you commit.

Certifications & Compliance

Hygienic areas get audited, so documentation matters as much as the board itself. Production is certified to ISO 9001, 14001, 45001 and 50001, facing coil meets EN standards with traceable mill certificates, and coating and foam declarations are supplied so your auditor can check what is actually in the wall.

Manufacturing Strength & Quality Control

Experience: sixteen years of continuous production, with hygienic-grade work a growing share of the order book.
Process: levelling, roll-forming, high-pressure foaming, curing and cut-to-length run as one continuous operation, so the board is never handled between bonding and finishing.
Inputs: coil, coating and foam chemicals are inspected on arrival and held against batch records.
In-process checks: bond strength, face flatness and core continuity are tested per batch, because a void behind a wash-down face is a hygiene failure waiting to be found.
Support: specification, quotation, certification and shipping papers come from a single team that knows the room schedule.

Lead Time, MOQ & Trade Terms

Item	Detail
Lead Time	Stocked depths 7-10 working days after deposit; cut-to-schedule orders 12-18 working days; samples 3-5 working days.
Minimum	From a single pallet upward - a trial room can be built out of stock.
Terms	FOB, CIF or DDP, named on the quotation.
Payment	Telegraphic transfer or sight letter of credit.
Packing	Faces filmed before stacking, corners protected, palletised and shrink-wrapped.

Aftercare

Support runs online and over video for jointing, coving and sealing. Manufacturing defects are put right with replacement boards and a written remedy rather than a debate, and you get progress photographs during production plus a named contact after delivery.

Company Profile & Call to Action

Send us the room schedule and we will return a cut list and a price. Production started in 2010 across 15,000 m2 of works at roughly 20,000 m2 a day, and hygienic-grade panels now ship to more than twenty countries.
