2. Geometric Single-Board Area (A_board = W × L / 1,000,000)
Outer physical rectangle of one delivered sheet (e.g. 1250 × 2500 mm = 3.125 m²). Factory edge squaring trim, saw kerf, and offcuts mean usable facade yield can be lower than outer sheet area.
3. Installed Effective Coverage Area (A_eff — Lap Siding & Interlocks)
Horizontal lap planks overlap the course below (typically 25–35 mm depending on clip/screw system). A 200 × 2500 mm plank has 0.50 m² outer area, whereas with a 30 mm overlap its installed effective coverage is 0.425 m².
4. Commercial Full-Pallet / Dispatch Quantity (A_pallet)
In international road and sea freight, partial loose sheets increase corner breakage risk. Theoretical board counts are normally rounded to safe export pallet multiples during formal quotation.

Frequently Asked Technical & Commercial Questions
What is the difference between nominal outer sheet size and usable cut module area?
Nominal outer size describes the delivered rectangular sheet (e.g. 1250 × 2500 mm). When cutting architectural facade cassettes, perimeter edge squaring trims (often 10–15 mm per edge on raw boards), saw blade kerf (3–4 mm per cut), and directional grain constraints reduce net yield. Always verify whether your facade grid requires factory-squared edges.
How does horizontal overlap affect board quantity on fibre cement cladding planks (siding)?
Lap cladding planks overlap horizontally to shed rainwater. For example, a 200 × 2500 mm plank has a geometric outer area of 0.50 m², but when installed with a 30 mm horizontal overlap its visible effective width is 170 mm (0.425 m² effective coverage per plank)—requiring roughly 17.6% more planks than raw outer m² before cutting waste.
What are the most common fibre cement board enquiry formats supplied from Türkiye?
For flat and wood/concrete/colour architectural boards, 1250 × 2500 mm (3.125 m²) and 1250 × 3000 mm (3.75 m²) are the primary enquiry formats. Brick-relief panels frequently use pattern-matched outer sheets such as 1225 × 2590 mm or 1225 × 3000 mm, while horizontal lap cladding planks are commonly requested in 170 / 200 mm widths by 2500 / 3000 mm lengths. Exact availability is confirmed per order.
Are fibre cement export shipments constrained by cargo volume or maximum payload weight?
Payload weight is almost always the governing limit. Because mineral fibre cement boards are dense, both road trucks and 20ft containers reach maximum legal gross payload well before their cubic volume is full. Accurate thickness and sheet count are therefore essential to calculate freight cost per m².
Can SerFibro evaluate cut-to-size facade modules or only full standard sheets?
Standard export supply focuses on full factory sheets and standard cladding planks for maximum transport safety and cost efficiency. Cut-to-size rectangular modules can be evaluated on a project basis when supported by a clear cutting list, repeatable module sizes, edge-treatment specification, and sufficient batch volume.
