B2B Integrated Package Policy

Supplied Exclusively as an Integrated System Package Alongside Fibre Cement Board Orders

Mineral stone wool insulation, vapour-permeable breather membranes, SerProfil galvanized or aluminium carrier sub-framing, UV EPDM joint gaskets, and facade fasteners are NOT sold as standalone retail hardware or loose insulation items. They are supplied strictly as an integrated B2B project package alongside SerFibro fibre cement board dispatches—or within turnkey facade engineering and application contracts coordinated by CFY Engineering & Architecture—guaranteeing 100% cross-layer compatibility, single-vendor commercial accountability, and zero wasted upper cubic volume in export containers and curtainsider trailers.

Inside-Out Envelope Engineering

6-Layer Ventilated Fibre Cement Rainscreen Wall Sequence

Every ventilated rainscreen facade relies on strict separation between the thermal/moisture barrier on the structural backup wall and the outer mineral cladding skin—separated by a continuously ventilated rear air cavity.

01 80–220 mm L-Consoles · Polyamide Thermal Pad

Structural Wall, L-Anchor Brackets & Thermal-Break Isolator Pads

Load-bearing galvanized steel or extruded aluminium L-brackets (80–220 mm projection) are anchored to reinforced concrete, masonry, or steel edge beams over rigid polyamide/PVC isolator pads that eliminate point thermal bridging and galvanic corrosion while compensating ±15–25 mm wall plumb tolerances.

02 EN 13162 · Class A1 · 70–110 kg/m³ · λ ≈ 0.035 W/mK

EN 13501-1 Class A1 Ventilated Facade Stone Wool & Mechanical Rosette Anchors

Water-repellent mineral stone wool slabs (50–150 mm thickness; black glass-veil faced for open-joint facades or uncoated) are slotted tightly over L-consoles with staggered joints and secured across the substrate using 5–6 pcs/m² wide-disc (Ø 60–90 mm) mechanical insulation anchors.

03 EN 13859-2 · Sd ≤ 0.02–0.05 m · Class W1 Watertight

Vapour-Permeable Watertight Facade Breather Membrane & UV Seam Tapes

Installed taut over the insulation outer face with ≥ 100 mm taped overlaps, the EN 13859-2 breather membrane allows outbound water vapour diffusion (Sd ≤ 0.02–0.05 m) while blocking wind-washing convective heat loss and driving rain ingress through open cladding joints.

04 SerProfil DX51D+Z / EN AW-6063 T6 · ≥ 20–40 mm Air Gap

Vertical Carrier Sub-Framing (SerProfil Galvanized M/J/C or Aluminium T/L) & ≥ 20–40 mm Air Cavity

Vertical carrier profiles at 400 mm or 600 mm axial spacing connect to L-brackets via one fixed dead-load point and remaining vertical sliding points per rail length—preserving a continuous ≥ 20–40 mm rear chimney air gap that removes summer solar heat and keeps the envelope dry.

05 EPDM 35–100 mm · Winged Screws / Ø 4.8–5.0 mm Rivets

UV-Resistant EPDM Joint Gaskets & Stress-Free Fixing Geometry

Black UV/ozone-resistant EPDM rubber profiles (35–40 mm on intermediate supports, 70–100 mm on joint rails) cushion board backs, shield metal flanges from rainwater, and create crisp dark joint shadows—combined with winged self-drilling screws on steel or large-head rivets + fixed/sliding centring sleeves on aluminium.

06 TS EN 12467 Cat. A · EN 13501-1 A1 · 8 / 10 / 12 mm

Outer Cladding Skin — SerFibro Board or SerFibro ColorBoard + Perforated Vent & Drip Profiles

Autoclaved Category A, Class A1 non-combustible SerFibro ColorBoard or paintable SerFibro Board panels (typically 8, 10, or 12 mm with 8–10 mm open architectural joints) shield the building against impact, freeze-thaw, and UV—finished at plinths, lintels, and parapets with perforated insect-screen vent grilles and drip profiles.

Weight-vs-Volume Freight Optimization

Why Co-Loading System Components Above Heavy Board Pallets Cuts Landed Freight Cost

Export Packing & Container Loading Guide

Autoclaved fibre cement is a high-density mineral material (~1,350–1,550 kg/m³). In both 20' DC ocean containers and 13.60 m European curtainsider trailers, board pallets reach the maximum legal payload weight ceiling while 25–35% of the upper interior cubic volume remains completely empty. Stowing lightweight stone wool packs, 75 m² breather membrane rolls, EPDM gasket cartons, fasteners, and bundled SerProfil / aluminium profiles in that unused headspace allows the complete facade system to travel with near-zero incremental freight cost under one customs set.

Co-Loading Payload & Cubic Volume Matrix Across Sea and Road Transport Modes
Transport Equipment Fibre Cement Payload Profile Unused Free Volume Co-Loaded System Package Scope
20' DC Heavy Container Floor-stacked pallets reach ~25–26.5 t payload ceiling quickly (~33 m³ total cube) ~25–30% upper headspace above strapped board pallets SerProfil / aluminium 3.00 m profile bundles, 75 m² breather membrane rolls, EPDM coils, L-brackets & fastener cartons
40' HC Mixed Container Same ~26–26.5 t port/road payload limit across ~76 m³ High-Cube internal volume ~35–45% high-volume capacity unused if loaded with dense boards alone Full envelope package including bulky Class A1 stone wool bales (50–120 mm), 3.00–6.00 m carrier rails, membranes & trims
13.60 m European Curtainsider Trailer EU road axle limits (~22–24 t cargo) fill trailer floor up to ~1.10–1.30 m pallet height ~30–35% clear upper trailer volume beneath 2.70–2.75 m roof height Top-stowed Class A1 stone wool slabs, breather membrane rolls, EPDM & SerProfil steel/aluminium sub-framing—eliminating separate LTL groupage

Frequently Asked Technical & Commercial Questions

Can I purchase stone wool, breather membranes, EPDM gaskets, or facade screws standalone without ordering SerFibro fibre cement boards?

No. SerFibro is not a retail hardware store or standalone insulation reseller. Mineral stone wool, vapour-permeable membranes, EPDM joint strips, and facade fasteners are supplied strictly as an integrated B2B system package alongside SerFibro fibre cement board orders—or within turnkey facade engineering and installation contracts managed by CFY Engineering & Architecture. (Dedicated wholesale production enquiries exclusively for cold-formed galvanized steel profiles may be evaluated separately through our group brand SerProfil.)

When should we specify SerProfil galvanized steel (M/J/C/U) versus architectural aluminium (T/L) carrier sub-framing?

SerProfil cold-formed galvanized steel sub-framing (DX51D+Z / S250GD+Z, 0.80–2.00 mm) provides high structural stiffness and clear budget efficiency on low-to-mid-rise residential, commercial, industrial, and light-steel modular buildings where boards are fixed with winged self-drilling screws. Extruded aluminium T/L sub-framing (EN AW-6063 T6, 1.8–2.2 mm) is engineered for high-rise wind zones, coastal/corrosive environments, deep insulation projections (100–150 mm), and through-coloured SerFibro ColorBoard facades specifying colour-matched large-head blind rivets with fixed and sliding centring sleeves.

Why are black glass-veil faced stone wool and a UV-stabilized breather membrane critical behind open-joint ColorBoard facades?

Architectural rainscreen facades typically leave 8–12 mm open vertical and horizontal joints unsealed to equalize wind pressure and ventilate the cavity. Through these open gaps, solar UV rays, wind gusts, and oblique rainwater reach the cavity interior, and any pale backing becomes visually noticeable. Black glass-veil faced Class A1 stone wool prevents fibre erosion under airflow while creating a clean dark shadow reveal, and an EN 13859-2 UV-stabilized Class W1 breather membrane stops wind-washing heat loss and water penetration while letting indoor vapour diffuse freely (Sd ≤ 0.02–0.05 m).

What is the engineering purpose of fixed-point versus sliding-point centring sleeves when fastening fibre cement panels?

Autoclaved mineral fibre cement panels and metallic carrier rails expand and contract at different thermal/hygric rates across winter-summer cycles. If every fastener rigidly clamps the panel, internal tensile stress builds around corner holes and causes hairline cracks. On aluminium T/L systems, two central fasteners receive exact-fit fixed-point sleeves to carry panel dead weight, whereas all surrounding fasteners sit concentrically inside oversized Ø 8.5–9.5 mm panel holes drilled via a centring sleeve with a calibrated stand-off nosepiece—allowing friction-free expansion in all directions.

How is mixed loading of heavy SerFibro board pallets and lightweight facade accessories organized for export containers and curtainsider trucks?

Edge-protected SerFibro board pallets are positioned evenly across the container or 13.60 m trailer floor deck first, keeping a low centre of gravity and respecting axle/gross payload limits (~22–26.5 tonnes). Lightweight breather membrane rolls, EPDM cartons, and stone wool packs are then stowed and lashed in the 25–35% free upper/rear cubic space without crushing board edges, while 3.00 m (or 6.00 m) SerProfil / aluminium profile bundles are secured in rigid timber-framed cradles—shipped under one commercial invoice, packing list, certificate of origin, and EUR.1 / ATR export set.

How are exact static L-bracket counts, profile wall thicknesses, and fastener schedules finalized before proforma confirmation?

Online calculator outputs serve for fast preliminary budgeting on standard flat walls. When you share architectural DWG/PDF elevations, building height, geographic wind zone, backup wall material (concrete, masonry, or steel frame), and target joint layout, CFY Engineering & Architecture evaluates EN 1991-1-4 corner vs central wind-suction loads, slab-to-slab spans, and window/parapet reveal returns—delivering an itemized B2B proforma schedule where boards, sub-framing, insulation, membrane, EPDM, and fixings match down to the pallet and bundle.
