The Series 45 casement door is defined by its 45mm ultra-slim frame profile — conceived specifically for high-end residential interiors where a modern, minimalist aesthetic is the governing design principle. By reducing the frame to its absolute structural minimum, the visual weight shifts entirely to the glass and the space beyond, creating a door opening that appears to float within the wall plane — clean, uninterrupted, and free of any superfluous detail.
Achieving a 45mm frame width places demanding requirements on both material strength and manufacturing precision. The Series 45 addresses this through an optimized internal cavity geometry and carefully distributed wall thickness, ensuring that the slender profile retains full structural rigidity and resistance to long-term deformation. The door sash remains true over years of use — no sagging, no warping, and consistently smooth operation from first installation onward. Hardware is selected and integrated with equal discipline: a recessed mounting approach keeps all fittings flush within the frame, preserving the unbroken purity of the profile silhouette.
Whether set against full-height glass partitions, expansive white walls, or warm timber flooring, the Series 45 integrates into any interior with studied restraint — becoming an essential design detail rather than a dominant element. For those who live by the philosophy that less is more, this is a door that means it.
