Invisible clip fixing
Groove routed into the back of the panel. Invisible stainless steel clips on aluminium rails. Perfect monolithic appearance — no fixing element visible on the facade. The standard for architectural projects.

Why ultracompact?
The most resistant facade material in the world.
Ultracompact panels — Dekton, Neolith, Lapitec, Laminam — are manufactured by sintering at very high temperatures. This process fuses minerals into a material of extreme density with near-zero porosity. The result: a panel of 8 to 20 mm thickness that resists UV without discolouration, freeze-thaw cycles without cracking, scratches without marking, and fire without propagation.
QUASART, based in Crauthem (L-3327), installs ultracompact panels on aluminium subframes with invisible or visible mechanical fixings. Large formats — up to 3,600 × 1,200 mm — enable monolithic facades of exceptional visual purity. We operate in Luxembourg, Moselle (Metz, Thionville) and Belgium (Arlon).

Fixing systems
Four systems. Zero compromise.
Visible rivet fixing
Flush stainless steel rivets, regular pattern. Economical and demountable solution. Individual panel replacement possible. Used on budget-conscious projects or facades requiring technical access.
Structural bonding
High-performance structural silicone. Result: monolithic facade with no visible metallic element. Requires strict surface preparation and quality control. Irreversible.
Ventilated aluminium subframe
Anodised aluminium uprights and cross-members, 3D adjustable brackets. Air gap 30-60 mm. Integrated insulation. The complete system constitutes a high-performance ventilated facade.
Formats & CNC cutting
Waterjet or CNC cutting for complex shapes, perforations and non-standard angles. QUASART relies on specialised workshops for precision cuts.
Joints & panel layout
Open joints (3-5 mm) or closed joints depending on the architectural intent. Layout to the mm integrating large format management and offcut optimisation. Plan validated with the architect before ordering.
Installation
Ultracompact installation techniques
Ultracompact is a noble but demanding material — the slightest handling error is irreversible.
01
Layout & offcut optimisation
Large formats (3,200 × 1,440 mm) require layout to the mm to optimise offcuts (expensive material). QUASART produces the layout plan before ordering slabs.
Before ordering · Offcut optimisation02
Handling & storage
Heavy panels (12 mm = ~30 kg/m²) and fragile in bending. Handling by suction cups, vertical storage on trestles. Any impact = panel lost — no repair possible.
Suction cups · Vertical · Zero impact03
Cutting & machining
Diamond disc or waterjet cutting for complex shapes. Back-face drilling for clips. Edges left raw or polished according to architectural detail.

Fixing & adjustment
Installation on laser pre-aligned aluminium subframe. Fixing by clips, rivets or bonding depending on the chosen system. Continuous plumb and flatness control.

FAQ
Questions about ultracompact facades
Dekton, Neolith, Lapitec, Laminam — everything you need to know
Dekton (Cosentino): TSP sintered panel at 25,000 °C, the most well-known. Neolith (TheSize): XL porcelain stoneware with high-definition NDD printing, the widest variety of decors. Lapitec: the only one rated A1, resin-free, vacuum-sintered — essential for high-rise buildings. Laminam: ultra-lightweight (5.6 mm), Italian large format. The choice depends on fire requirements, format and budget.
Yes. Water absorption < 0.1% — totally resistant to freeze-thaw cycles. An intrinsic property of sintering: pores are completely closed. All Dekton, Neolith, Lapitec and Laminam ranges are certified for unrestricted outdoor use in any climate.
Lapitec is rated A1 — suitable without restriction for high-rise and public buildings. Dekton and Neolith are A2-s1,d0 — compatible with most buildings subject to technical approval. QUASART verifies regulatory compliance for each project.
In supply terms, prices are comparable: 80-200 EUR/m² depending on format and finish. The advantage of ultracompact: perfect uniformity, superior mechanical resistance, no staining, no UV discolouration. Installation on subframe is similar. Total budget: 250-500 EUR/m² installed.
Yes — intrinsically. The near-zero porosity prevents any penetration of paint solvents. High-pressure cleaning or a mild solvent is sufficient. This is one of the most widely used materials on public buildings and transport for this reason.
Dekton Stonika: 3,200 × 1,440 mm. Neolith: 3,600 × 1,200 mm. Lapitec: 1,500 × 3,365 mm. Laminam: 3,000 × 1,000 mm. Thicknesses: 5.6 mm (Laminam), 6 mm (Neolith), 8-12-20 mm (Dekton, Lapitec). Large formats create a monolithic effect with no visible joints.
