Are Wulf systems certified for coastal Nordic climates?

What warranties do you provide on glazing and hardware?

Our triple-glazed aluminium and wood-aluminium windows achieve U-values as low as 0.78 W/m²K, exceeding modern Swedish passive house standards for extreme thermal retention.

We manage the entire lifecycle. Our local Swedish teams perform high-precision digital laser scans of your structural openings, coordinate delivery, and execute the complete weather-sealed installation.

Yes. All frames undergo rigorous wind-load, water-tightness, and air-permeability testing. Our powder-coated aluminium profiles carry marine-grade Qualicoat Seaside certifications to resist salt corrosion.

We provide a comprehensive 10-year structural warranty on all aluminium frames and triple-glazed units, alongside a 5-year warranty on premium German-engineered hardware and weather-seals.
