Why HPL?
The aesthetic armour that lasts 30+ years.
HPL stands for High Pressure Laminate. Kraft paper sheets impregnated with phenolic resin, compressed at over 70 bar and 150 °C. The result: a panel with a density of 1.35 g/cm³, harder than most woods, resistant to UV, water, impacts and graffiti. HPL is not a coating — it is an aesthetic armour.
QUASART, based in Crauthem (L-3327), works with the three European leaders — Trespa (Netherlands), Fundermax (Austria) and Rockpanel (Netherlands). Over 1,200 decors available: plains, photorealistic wood, polished concrete, natural stone, brushed metal. Custom CNC cutting. Visible fixing, hidden fixing or structural bonding.

Installation
HPL fixing systems
Hidden fixing · Clips
Metal clips on aluminium subframe — perfectly smooth facade, no visible screws. Allows individual panel replacement. Recommended for architectural projects.
Structural bonding
High-performance structural silicone on aluminium profiles. Result: monolithic facade with no visible metallic element. Strict surface preparation and quality control. Irreversible.
Rivets & special systems
For complex geometries, curved facades or partial replacement situations — QUASART adapts the fixing system to the context with manufacturer-validated hybrid solutions.
Installation
HPL installation techniques
Thermal expansion is the critical parameter for HPL — precise layout planning is non-negotiable.
01
Layout & expansion joints
Layout plan to the mm integrating expansion joints (8-12 mm), corner junctions and window cut-outs. Validated with the architect before panel ordering.
Before ordering · Non-negotiable02
Aluminium subframe
T or L aluminium profiles, fixed to masonry or load-bearing structure. Ventilated air gap 20 mm minimum. Load calculation per Eurocode and DTU 41.2.
Alu · 20 mm · Eurocode03
Custom CNC cutting
Workshop cutting on CNC machine — freeform shapes, perforations, engraving. Precision to 1/10 mm. Edges machined or protected with touch-up paint.
CNC · 1/10 mm · Protected edges04
Thermal management
Expansion ~0.05 mm/m·°C. On a 3 m panel, expansion reaches 7.5 mm between -10 °C and +40 °C. Fixings must allow free panel movement.

Standards & certifications
Every QUASART installation complies with current European and local standards — from fire classification to subframe rules.
EN 438
HPL — High pressure laminates
European standard defining the physical and mechanical properties of compact HPL panels. Classification by grade and thickness.
EN 13501-1
Fire classification of materials
Euroclass B-s1,d0 for standard HPL, A2 for Rockpanel. Determines use in public and high-rise buildings.
DTU 41.2
Lightweight facade installation
French Technical Document applicable to HPL panels in ventilated facades — subframe, fixings, joints, minimum 20 mm air gap.
EAD 090062
European Technical Assessment
European approval specific to lightweight facade systems — basis for CE certifications for HPL fixings and subframes.
ISO 1183
Density determination
Plastics density measurement standard — guarantees compact HPL density ≥ 1.35 g/cm³ per manufacturer specifications.
RE 2020 / GPE
Thermal compatibility
HPL panels in ventilated facades are compatible with RE 2020 (France) and GPE (Luxembourg) — Ug values and thermal bridges integrated in calculation.
Applications
Wherever durability is non-negotiable
01
Public & school buildings
Facilities subject to the strictest fire regulations. Rockpanel A2 or Trespa B-s1,d0. Impact and graffiti resistance essential.
02

03
Offices & commercial
Headquarters facades, business parks — impeccable corporate image without intensive maintenance. Fundermax Max Exterior for long runs.
04
Degraded facade renovation
Replacing ageing cladding — corroded metal, cracked render, asbestos fibre cement — with a ventilated HPL system. Long-term solution, zero maintenance.

FAQ
Everything you need to know about HPL
The real questions asked by architects, developers and clients
Trespa Meteon: high-end reference, co-pressed surface layer, maximum UV/graffiti resistance, photorealistic decors. Premium price. Fundermax Max Exterior: optimal quality/price ratio, 180 colours, AGT anti-graffiti treatment. Rockpanel: only true non-combustible (rock wool, class A2) — essential for category 1 public buildings. The choice depends on your fire regulation, budget and desired decors.
Yes, systematically. HPL panels expand ~0.05 mm/m per degree Celsius. On a summer day in Luxembourg (ΔT 50 °C), a 1.2 m panel expands by 3 mm. Without joints, the panel buckles or cracks within 2 to 5 years. QUASART integrates expansion joints in the layout plan from the quotation stage.
30 to 50 years under normal conditions. Manufacturers guarantee their panels against discolouration and delamination for 10 to 25 years depending on range. An HPL correctly installed by QUASART per DTU 41.2 requires zero maintenance for 30 years.
Yes. HPL is installed on an aluminium or timber subframe fixed to the supporting wall, with or without insulation. For renovation with thermal improvement (RE 2020 / GPE), insulation is fitted between battens. QUASART carries out a structural and thermal survey before quotation.
Yes — it is one of the main reasons for their specification on public buildings. The HPL surface (especially Trespa Meteon and Fundermax AGT) is impervious to spray paint solvents. High-pressure cleaning is sufficient in 90% of cases — the graffiti comes off without residue.
Compact HPL is a thermoset — not recyclable at end of life. Its environmental balance improves with lifespan: an HPL lasting 40 years has a much lower annual carbon footprint than PVC cladding replaced every 15 years. Trespa offers panels with recycled fibres (NFC range). Rockpanel uses natural rock wool.
