Fereastră LEMN-ALUMINIU HV450 Home Pure — Triplu, Passivhaus

Wood-aluminium window with triple glazing and superior thermal insulation (Uw 0.62 W/m²K), PassivHaus certified, featuring integrated blinds and RC1N/RC2 burglary protection.

The HV450 Home Pure series from Internorm represents the modern evolution of the wood-aluminium window, engineered for homes demanding the highest standards of comfort and energy efficiency. The combination of solid wood on the interior and aluminium protection on the exterior ensures exceptional durability, whilst the fluid transition from frame to sash creates a sense of architectural harmony and seamless integration.

The triple glazing system with low-e technology and high-performance thermal spacers achieves a Uw value down to 0.62 W/(m²K), positioning the window within passive house and ultra-low energy building categories. Sound insulation reaches 39–47 dB, neutralising ambient noise and creating a tranquil interior environment. The wood and aluminium profile is optimised to minimise thermal bridges, delivering consistent performance across the entire surface.

PassivHaus certification underscores compliance with the world's most stringent efficiency standards. The window withstands extreme wind loads and water infiltration with ease, thanks to its hermetic construction and integrated drainage system. RC1N and RC2 burglary protection provides peace of mind for security-conscious families without compromising optical clarity or views.

Integrated blinds between the glass panes are the defining feature of the Home Pure range, eliminating the need for external systems and embedding shading into the window assembly itself. This solution saves space, reduces infiltration, and offers precise control over light and temperature. Profiles are available in natural wood tones and various finish options, allowing perfect alignment with interior architecture.

HV450 is recommended for energy retrofits, passive house projects and new construction in continental and oceanic climates. Professional installation and application of specific sealants guarantee durability exceeding 30 years, transforming the investment into long-term comfort and savings.

The HV450 achieves Uw 0.62 W/(m²K), placing it in the highest performance category for passive and NZEB homes. With triple glazing and warm-edge spacer, heat loss is minimized, reducing long-term energy consumption and recovering your investment through significant annual savings.

The integrated blinds are positioned between the triple glazing panes, protected from dust and external damage. They can be operated manually via cord/pulley or electrically with discreet motors, providing precise light control and solar shading without requiring extra wall space.

RC1N provides protection against spontaneous break-in attempts and everyday vandalism, suitable for standard residential homes. RC2 offers high-level security with multi-point hardware and safety glass, resisting sustained attacks with tools and manual force, recommended for properties with elevated risk profiles.

The exterior aluminium shields the wood from UV, moisture, and temperature fluctuations, significantly extending durability. Interior wood retains natural aesthetics and superior thermal performance. Maintenance involves annual cleaning and occasional paint/varnish touch-ups, requiring no major restoration for 20–30 years when protocols are followed.

HV450 provides acoustic insulation Rw 39–47 dB, reducing ambient noise by 50–70% depending on glazing configuration and acoustic treatment. Triple glazing with separated panes and gas layers creates multiple barriers attenuating both high and low frequencies, essential for homes near roads or busy urban areas.

HV450 is custom-manufactured to your exact dimensions and specifications. Installation is performed by certified Internorm specialists ensuring perfect sealing and compliance with performance standards. Professional on-site measurement is recommended to guarantee optimal fit and prevent sealing issues.
