HS 330 LEMN/ALUMINIU

The Internorm HS 330 wood-aluminium window combines solid timber craftsmanship with contemporary performance. Offered in an extensive palette of wood species and colours, it adapts seamlessly to any architectural vision.

The HS 330 Lift & Slide series from Internorm is a premium window solution that celebrates the relationship between interior and exterior spaces through refined design and superior performance. The wood-aluminium construction is tailored for discerning homeowners who appreciate Austrian craftsmanship and seek architectural integration that is both understated and impactful.

The profile unites a solid timber frame—sourced from noble wood species—with a protective aluminium cladding on the exterior face. This dual-material approach delivers optimal thermal insulation within the living space, while the aluminium resists weather exposure and requires minimal maintenance. The window can be fitted with triple-glazing systems achieving exceptional Ug values, ensuring year-round thermal comfort in any climate zone.

The HS 330 is engineered for passive house standards and high-efficiency energy performance criteria. Acoustic properties are equally robust, providing effective sound insulation against urban noise pollution. Three-line sealing systems and structural rigidity against wind pressure and water infiltration guarantee longevity regardless of exposure conditions. Compliance with regional building codes is assured through rigorous quality protocols.

The finish palette is comprehensive: the interior face offers an array of timber species in natural or stained finishes, customisable in any RAL colour; the aluminium exterior permits the same chromatic flexibility. The profile's architecture—defined by slender sight lines and geometric clarity—integrates seamlessly into contemporary, traditional, or heritage renovation contexts.

Recommended for residential projects with demanding thermal specifications, certified passive houses, facade renovations in temperate or continental climates, and for clients who value the natural warmth of timber allied with advanced technical performance. Installation is handled by specialist Internorm teams, ensuring precise integration within building envelopes.

The triple glazing on HS 330 delivers thermal insulation down to Uw 0.73 W/(m²K), perfect for passive houses and NZEB standards. This means significantly lower heating bills in winter and superior thermal stability year-round, ensuring maximum comfort regardless of weather.

HS 330 delivers uninterrupted panoramic openings and slides on a flat threshold, engineered for seamless indoor-outdoor flow. This design allows the window frame to blend elegantly into open-plan spaces, transforming the transition zone into a visual extension of your home.

The aluminum exterior shields solid wood from UV, rain, and extreme temperature swings, significantly extending durability. The interior wood ensures natural thermal insulation and warm aesthetics, while aluminum guarantees long-term architectural resilience with minimal maintenance.

HS 330 provides acoustic insulation Rw 32–40 dB, reducing street noise to comfortable levels. For security, it offers RC1N and RC2 classes with multi-point hardware and triple glazing that resist forced entry – ideal for urban areas and homes requiring more than basic safety standards.

HS 330 comes in a wide range of customizable wood species and colors, suited to any architectural style – from classic finishes to contemporary design. Each window is produced to order, ensuring perfect integration with your walls, trim, and home's interior palette.

HS 330 is manufactured to your exact measurements and installed by authorized Internorm specialists who ensure airtightness and optimal thermal performance. Installation includes testing of gap integrity and lift & slide mechanism operation to guarantee decades of reliable service.
