Elegantly designed concealed hardware gives the HF 410 a refined, high-quality appearance – complementing the natural warmth of the timber without any visible ironmongery.Pairs Perfectly With the KF 410

The Warmth of Timber, the Freedom of Low Maintenance
Timber windows have always had a quality that other materials struggle to match – a natural warmth, a richness of grain, a feeling that your home has been finished with care. The HF 410 delivers all of that, with the added reassurance of an aluminium-clad exterior that takes care of itself season after season.
The choice of timber species – oak, spruce, larch, ash, or walnut – means your windows can be selected to flow through from the architecture outside to the interior design inside. Match them to your flooring, your joinery, your doors. The result is a home that feels genuinely curated, not assembled.
