Architectural facade visuals illustrating real texture, joint modulation, and profile details for this fibre cement series. Available as standalone material supply or with integrated project consultancy, facade engineering, and application.
SerFibro Window Jamb & Architrave Profiles are 20 mm thick autoclaved fibre cement facade trims designed to frame window openings, exterior doors, reveals, and building corners with crisp architectural relief and full Class A1 fire safety.
The range covers Flat and 45° Beveled profiles in 80, 100, 150, and 200 mm widths alongside four stepped decorative architrave profiles: PS-01 (100 mm), PS-02 (120 mm), and PS-03 / PS-04 (150 mm), all supplied in 2500 and 3000 mm lengths.
Window openings are the primary pathway where interior flames leap onto exterior facades. Framing windows with Class A1 non-combustible fibre cement trims instead of EPS foam prevents molten dripping and flame propagation around glazing.
Supplied natural grey or factory alkali-primed, SF-JAMB profiles accept exterior acrylic and silicone facade coatings—enabling crisp off-white surrounds on dark slate/stone facades or anthracite frames on light elevations.
Stepped PS-01..04 profiles are typically miter-cut at 45° at upper window corners so the stepped relief wraps continuously around the opening, whereas Flat and 45° Beveled profiles also support clean vertical-over-horizontal butt framing and external wall corners.
Prefabricated steel-frame house builders pair 80 / 100 mm Flat and 45° trims with SF-SIDING lap planks around windows and external corners, while urban apartment and hotel architects specify 120 / 150 mm PS-series frames with SF-CORNICE floor bands.
Fix 20 mm jamb bars mechanically (stainless countersunk screws) backed by exterior polyurethane adhesive, and leave a flexible UV-resistant mastic joint between the fibre cement bar and the aluminium/PVC window frame to accommodate differential thermal movement.
Ground-floor window surrounds and door jambs suffer frequent knocks from maintenance equipment, hail, and birds. Solid 20 mm autoclaved fibre cement resists indentation, moisture ingress, and freeze-thaw delamination under EN 12467 Category A.
Match 2500 mm or 3000 mm bar lengths to window heights (e.g. a 1400 × 1500 mm window takes two vertical legs + one top lintel from two 2500 mm bars with minimal offcut). Include 8–10% allowance for 45° miter cuts.
Every full pallet across the SF-JAMB range equals 90.0 m² geometric area: from 450 pcs (80×2500 mm) and 360 pcs (100×2500 mm) to 300 pcs (120×2500 mm), 240 pcs (150×2500 mm), and 150 pcs (200×3000 mm), simplifying freight weight calculation.
Keep pallets wrapped on flat timber bearers indoors away from standing water or mud splashes. Wipe dry sawing dust off immediately before any moisture contacts the primed surface.
Order SF-JAMB window trims standalone or consolidated alongside SerFibro facade panels, lap siding, and KS-01/02 cornices under EXW, FCA, FOB, CIF, or DAP export delivery terms.
Architects and developers can request short physical cross-section samples of Flat, 45° Beveled, and PS-01..04 profiles to evaluate shadow depth against window frame mock-ups.

Yes. Light-steel prefab and villa builders widely use 20 mm thick 80 mm and 100 mm Flat or 45° Beveled bars as crisp vertical corner boards against 8 / 10 mm horizontal lap-siding planks, creating a clean stop edge.
Yes. Autoclaved SerFibro jamb profiles achieve TS EN 13501-1 Class A1 reaction-to-fire performance, making them safe around window lintels and escape routes where EPS foam trims are prohibited.
Each full pallet holds 90.0 m²: for 2500 mm bars, 450 pcs (80 mm), 360 pcs (100 mm), 300 pcs (120 mm), 240 pcs (150 mm), or 180 pcs (200 mm); for 3000 mm bars, 375, 300, 250, 200, or 150 pcs respectively.
