Wall and Facade Sandwich Panels: Architectural Aesthetics & Energy Efficiency
Our wall and facade sandwich panel systems combine premium architectural aesthetics with high thermal performance. Available in standard through-fix (W) and concealed-fix (WM / secret-fix) configurations, they accommodate horizontal and vertical orientations with micro-ribbed or flat surface options, backed by 120-minute A1 rockwool fire barriers.

Key Engineering & Commercial Benefits
Concealed-Fix Architectural Facade
Interlocking tongue-and-groove pockets conceal fasteners, creating a screw-free monolithic facade.
Double Interlocking Air Barrier
Precision factory gaskets eliminate thermal bridging and uncontrolled air leakage through joints.
Horizontal & Vertical Versatility
Engineered for direct span across primary columns horizontally or facade girts vertically.
A1 Non-Combustible 120-Min Firewall
Dense stone wool core options deliver certified 120-minute structural fire containment (EI120).
Available Systems & Models
Select the optimal profile and core configuration for your building envelope requirements.
Standard PUR wall panels provide fast installation and dependable weather sealing for exterior walls and internal partitions in warehouses and production facilities.
Engineered with an isocyanurate chemical ring structure that chars on flame contact without dripping, PIR wall panels satisfy stringent building code and industrial insurance (FM Global) requirements.
Concealed-fix panels hide all fasteners within the joint tongue, creating clean architectural shadow lines, uniform facades and preventing water ingress at screw points.
Manufactured with vertically oriented high-density rockwool basalt slabs (100 kg/m³) to deliver structural stability, acoustic damping, and Class A1 non-combustible fire resistance up to EI 120. Ideal for industrial firewalls, hazardous storage, petrochemical plants, and building envelopes requiring official fire department accreditation.
EPS wall sandwich panels offer the most budget-friendly envelope solution for modular container camps, temporary construction offices, partition walls, and prefabricated housing.
Engineered with internal factory-perforated steel facings and an acoustic fleece backing, these rockwool panels provide exceptional sound absorption (NRC 0.85) alongside A1 non-combustible fire barrier protection for power plants and manufacturing floors.

Critical Engineering Guidelines for System Selection
Standards for purlin spacing, live loads, fire containment and joint detailing.
1. Standard Through-Fix vs. Concealed-Fix (Secret-Fix)
Standard through-fix (W) panels expose fastener heads fitted with color-matched caps, offering fast installation and low cost. Concealed-fix (WM / secret-fix) panels feature an interlocking tongue-and-groove joint where screws are hidden inside the joint pocket, creating an uninterrupted architectural monolithic facade.
2. Horizontal vs. Vertical Wall Panel Installation
Vertical installation runs continuous lengths from parapet to slab, fastening directly to horizontal wall girts. Horizontal installation fixes panels across building columns, creating contemporary linear proportions. Column joint lines are detailed with matching flashings or architectural aluminum extrusions.
3. Wind Suction Load Calculation & Facade Girt Sizing
Wind suction generates intense outward loads, especially on building corners and parapet perimeters. Girt spacing should range between 2.20m and 2.50m for 50mm panels, reinforced with dual fixing clips at vulnerable building corners.
4. Fire Compartment Partition Walls & Permitting Standards
Industrial fire codes mandate non-combustible A1 materials along plot boundaries and partition firewalls. 100mm Rockwool panels deliver EI120 fire barrier ratings required for municipal fire compliance approvals.
5. Micro-Ribbed, Linear and Flat Facade Surface Finishes
Micro-ribbed profiles prevent optical wave distortion (oil-canning) on long exterior facades. Flat finishes with reinforced 0.60-0.70mm steel gauges provide crisp architectural minimalism.
6. Base Drip, Corner Flashing & Weatherproofing Details
Panels never sit directly on raw concrete. A base galvanized U-channel bedded in butyl sealant provides level alignment, paired with sub-base drip flashings to shed rainwater safely clear of foundations.
Matching Flashings, Screws & Trims Package
Coordinated single-delivery guarantee: Color-matched flashings, EPDM fasteners, and covings.
Bottom Base U-Channel
Prevents panels from contacting raw concrete and ensures plumb alignment.
External & Internal Corner Flashings
Weatherproofs external and internal corner junctions against driving rain.
Base Drip Flashing
Directs facade runoff away from foundations and concrete plinths.
Secret-Fix Mounting Clips
Clamps interlocking tongue-and-groove joints without surface damage.
Polyurethane Facade Sealant
Completes air and vapor tightness along longitudinal joints and flashings.
Aluminum Omega & Joint Profiles
Cleanly covers horizontal stack joints across column gridlines.
