Fereastră PVC-ALUMINIU KV440 Home Soft — Triplu, Passivhaus

KV440 Home Soft PVC-Aluminium window with rounded interior lines and a warmer visual tone. Delivers top-class energy performance (Uw up to 0.64 W/(m²K)) and strong acoustic comfort for premium living.

KV440 Home Soft keeps the advanced technical base of the KV440 family while shifting the aesthetic language toward a softer expression. Interior contours are gentler, making it a strong match for residential interiors that use warm tones, natural materials, and organic furniture lines.

Performance remains high-efficiency oriented: triple glazing, Uw values up to 0.64 W/(m²K), strong airtightness, and consistent acoustic protection. KV440 Home Soft is recommended when you want premium technical standards with a less austere look than the Pure version.

The exterior aluminium provides superior UV protection and enhanced mechanical resistance against weather exposure, extending the window's lifespan. The inner PVC core maintains exceptional thermal performance, while the aluminium layer delivers a clean architectural line and minimal glass and hardware maintenance.

Yes, with a Uw coefficient of up to 0.64 W/(m²K) and triple glazing with warm spacer, KV440 Home Soft meets NZEB and passive house requirements. Superior thermal performance minimizes heat loss and significantly reduces heating demand, making it ideal for premium renovations and new builds with very low energy consumption.

RC2 provides protection against attempted burglary with moderate mechanical force — the glass resists cutting and mechanical pressure, as well as repeated impacts with common objects. Multi-point locking hardware and advanced locking system make the force required to breach the window prohibitive for casual intruders, significantly raising home security.

The acoustic index Rw of 39–45 dB is achieved through the combination of triple glazing with different thicknesses and warm spacer that absorbs vibrations. Each additional decibel represents a noticeable reduction in noise; a 5 dB difference is perceived as roughly 50% reduction in perceived intensity. For homes in urban areas, this combination ensures significant reduction of traffic noise and other external sources.

KV440 Home Soft supports integrated blinds — an elegant solution that combines solar screening with the window, eliminating the need for an external system and offering precise control of light and heat. The PVC-Aluminium profile allows a wide palette of colors for glass and frame, adapted to your home's architecture. Sizing and finishes are made to order, ensuring perfect integration with your project.

KV440 Home Soft requires precise sizing and custom installation to ensure airtightness and optimal thermal performance. Installation must be performed by qualified specialists following Internorm protocol — faulty installation voids the warranty and compromises performance.
