The Versatility to Suit Every Room, Every Style
What makes the KF 410 genuinely special is the degree of choice it offers. Four design styles – flush, square-edged, rounded, and contoured – mean you can select a profile that feels right for your home, rather than settling for whatever happens to be in stock. Each style carries the same outstanding performance credentials beneath it.
The option to combine the KF 410 with the timber-aluminium HF 410 adds another layer of flexibility. Use uPVC aluminium in bathrooms and utility spaces where practicality is paramount, and timber-aluminium in your living areas where warmth and character matter – all with a consistent, unified appearance on the outside.
