FRP passive house windows for German projects

No. The EU's anti-dumping duties on Chinese aluminum extrusions (Regulation (EU) 2021/546, 21.2%–32.1%) apply to aluminum profiles, so aluminum window systems made with Chinese extrusions carry that cost. In its definitive regime, CBAM prices the embedded carbon in imported iron, steel, and aluminum goods, including aluminum door and window frames (CN 7610) and steel doors and windows (CN 7308 30). Pultruded FRP (fiberglass-reinforced polymer) fenestration is a glass-fiber composite classified under HS 3925.20 or 7019, placing it outside both the anti-dumping orders and CBAM. Standard EU customs duties and Germany's 19% import VAT (Einfuhrumsatzsteuer) still apply and are itemized in our DDP Germany quote.

Windows placed on the EU market carry CE marking under EN 14351-1 with a Declaration of Performance — air permeability (EN 12207), watertightness (EN 12208), and wind-load resistance (EN 12210) type testing is arranged per project at an accredited European laboratory such as ift Rosenheim. Thermal performance is calculated to EN ISO 10077, and the frame's Passive House credential is the PHI Component Certificate 2491wi03 (U_w = 0.78 W/m²·K, phB class) issued by the Passive House Institute in Darmstadt — the body that wrote the standard.

Yes, with margin at every tier. The GEG 2024 reference building assumes a window U_w of 1.3 W/m²·K; BEG funding for a single window-replacement measure requires U_w ≤ 0.95; and a PHI-certified component for the cool-temperate climate zone must reach U_w ≤ 0.80. Our 90-series GFRP-PU frame is certified at U_w 0.78 W/m²·K (PHI 2491wi03, phB). Because the entire pultruded frame is intrinsically insulating (≈ 0.3 W/m·K versus 160 for aluminum), there is no metallic thermal-break path or steel reinforcement conducting heat as there is in uPVC frames.

Standard schedule from PO: 4–6 weeks production + 30–35 days sea freight to Hamburg, Bremerhaven, or Rotterdam. Total PO-to-jobsite is typically 9–13 weeks DDP. For inland destinations (Munich, Frankfurt, Berlin, the Ruhr) we deliver DAP via truck or rail from the port of entry. Urgent samples or replacement parts ship air freight ex-Shanghai to any major German hub in 4–6 days at premium cost.

Yes. We quote DDP to your German jobsite in EUR or USD, with EU customs duty and 19% import VAT itemized so your quantity surveyor sees the full landed cost up front. We classify under HS 3925.20 or 7019 depending on configuration, ship with our EU customs broker handling clearance, and provide full supply-chain traceability documentation with every shipment.

Both models run in parallel. For Passivhaus and Effizienzhaus projects that want guaranteed factory airtightness, we ship complete GFRP-PU window units — assembled, glazed, gasketed, and leak-tested, including tilt-turn (Dreh-Kipp) configurations in the 80-series. For Germany's established window-fabrication industry (Fensterbau), we supply the pultruded profile set — frame, sash, mullion, transom, glazing bead — plus co-extruded EPDM gasketing and fabrication drawings, so a German fabricator assembles locally. F1 holds 800+ existing die sections and pultrudes on its own lines (5 bases, 370 lines), so engineered profiles often skip new tooling; finishes are AAMA 2604/2605 architectural powder coating in any RAL color.
