Fereastră PVC-ALUMINIU KV440 Home Soft — Triplu, Passivhaus

Internorm KV440 Home Soft PVC-Aluminium window delivers outstanding thermal insulation (Uw 0,64 W/m²K) with triple glazing and advanced security, perfect for Passive House standards and premium refurbishment.

The KV440 Home Soft series from Internorm's portfolio represents a high-performance solution for modern homes that prioritize energy efficiency and comfort. The hybrid PVC-Aluminium construction combines the superior thermal insulation advantages of PVC with the durability and exterior elegance of aluminium profile, creating a window that adapts perfectly to both cold and temperate climates.

The triple-glazing system with Uw values down to 0,64 W/m²K positions this window among the most efficient on the market, compliant with Passive House standards. The low-e glass and optimized spacing between panes ensure minimal thermal loss while maintaining crystal clarity and natural light comfort. Deep frames with specially treated glass reduce condensation and maximize interior heat retention, even in extreme seasonal conditions during cold winters.

Sound insulation rated Rw 39–45 dB guarantees interior tranquility regardless of traffic noise or environmental factors. RC2 certification for break-in resistance provides reliable protection without compromising design elegance. The PVC frame resists moisture-induced deformation and thermal stress, ensuring long-term durability and consistent performance throughout the window's lifespan.

Integrated options—built-in blinds and I-tec ventilation—allow effortless management of airflow and direct light without additional devices. Integrated blinds protect privacy and regulate temperature seasonally, while the controlled ventilation system ensures fresh air exchange without significant thermal loss. Available RAL colour palettes and finishes permit discreet architectural integration or deliberate design accents, adaptable to any home style.

KV440 Home Soft is recommended for energy renovation projects, new builds with Passive House requirements, and homes in regions with harsh winters. Professional installation in solid frames guarantees maximum performance over 40+ years of use.

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. We recommend a free sizing consultation to confirm compatibility with your openings and assess opening preparation requirements.
