KF 410

Our Internorm KF 410 uPVC windows are available from Thames Valley Windows throughout Berkshire, Surrey, Hampshire, and the Southeast.

The KF 410 is a high-performing flush uPVC triple-glazed window. It offers a unique blend of classic design and versatile functionality. Its exceptional thermal insulation, sound reduction, and interior customisation options make it a top choice for homeowners and architects.

Available in three design styles – Home Soft, Home Pure, and ambiente, offering flexibility to suit a range of traditional and contemporary properties

The KF 410 windows are not just functional, but also a design statement. Designed for a clean and unobtrusive look, the flush transition of frame and sash combines KF 410 into one unit, creating a sleek and modern aesthetic.

When the narrow, square-edged sash frame is rendered into the brickwork on three sides, only the narrow, square-edged sash frame remains visible.
