What Is an HPL Sandwich Panel?
HPL — high-pressure laminate, also called melamine resin panel — is 4 mm thick and built from more than 40 layers of paper impregnated with melamine and phenolic resin, cured under high heat and pressure into one dense, solid sheet. As a panel facing it delivers excellent fire resistance and thermal insulation, plus corrosion resistance, impact resistance, a good decorative surface and availability in multiple colors. The HPL sandwich panel bonds this laminate to an insulated core, giving a hygienic, low-maintenance wall or ceiling. The same material is used for our HPL cleanroom door and HPL ceiling system.
Inside the HPL Laminate — 40+ Layers
The 4 mm HPL face is then bonded to an insulated core (PIR, rock wool or honeycomb) to form the finished sandwich panel.

Surface Performance
HPL Facing vs Metal Facing — Which to Choose?
| Aspect | HPL facing | Metal (steel) facing |
|---|---|---|
| Surface look | Decorative, many colors & wood grains | Industrial, limited colors |
| Chemical resistance | Excellent | Depends on coating |
| Scratch & impact | High resistance | Can dent / show marks |
| Hygiene / cleaning | Non-porous, easy disinfect | Easy to clean |
| Best suited to | Labs · hospitals · food · medical | General industrial cleanrooms |
Behind the HPL face you can choose an insulated core: PIR, rock wool or aluminum honeycomb. Prefer a metal-faced option? See the cleanroom sandwich panel range, or the dedicated HPL cleanroom panel and medical cleanroom panel.
Where HPL Panels Are Used
Technical Insights & FAQ
What is HPL and how is it made?
HPL (high-pressure laminate / melamine resin panel) is 4 mm thick and made from more than 40 layers of paper impregnated with melamine and phenolic resin, cured under high heat and pressure into one solid, durable sheet.
Is HPL fire resistant?
Yes. HPL offers excellent fire resistance along with thermal insulation. For projects with strict fire codes we can pair the HPL face with a non-combustible rock wool or MGO core.
How chemical- and scratch-resistant is the surface?
The melamine overlay gives strong corrosion, chemical, scratch and impact resistance, and the non-porous surface is easy to disinfect — well suited to labs, hospitals and food facilities.
What colors are available?
HPL comes in multiple colors and wood grains — popular cleanroom shades include swan white, snow white, coconut white, ivory, soft pink, sea green and light blue. Request a color card for exact shades; custom colors are available.
When should I choose HPL over a metal facing?
Choose HPL when you want a decorative, color-rich, highly chemical- and scratch-resistant, easy-to-disinfect surface — typical in labs, hospitals and medical or food environments. Metal facings suit general industrial cleanrooms.
Can HPL be used for ceilings and doors too?
Yes. The same HPL is used for our HPL ceiling system and HPL door, so walls, ceilings and doors can share one consistent finish.
