Fereastră LEMN-ALUMINIU HF310 Studio — Triplu, Passivhaus

Internorm HF310 Studio window in wood-aluminium construction with triple glazing, thermal value Uw 0.71 W/(m²K) and PassivHaus certification for maximum comfort.

The HF310 Studio is a reference window from Internorm's collection, engineered for contemporary homes that value the warmth of natural wood. The hybrid wood-aluminium structure merges the thermal character and durability of wood with the strength and weatherproof protection of an external aluminium cladding, delivering a solution both sustainable and timeless.

The eight-chamber profile ensures exceptional structural rigidity and a thermal performance of 0.71 W/(m²K), validated by PassivHaus certification. Triple glazing with low-emissivity coating and noble gas fills between panes minimises heat loss and maintains consistent interior temperature year-round. Dual-seal gaskets provide reliable protection against water infiltration and wind pressure, tested to withstand demanding climates.

Beyond thermal excellence, HF310 Studio achieves sound insulation ratings of 33–46 dB, suitable for both urban environments and quieter suburban settings. RC2 security classification confirms resistance to forced entry through strengthened glazing and reinforced hardware, protecting your home without sacrificing aesthetic refinement.

The vertically-oriented profile creates a slender, elegant appearance that harmonises with both traditional and contemporary architecture. Available wood finishes—oak, pine, birch—and RAL colour options on the aluminium exterior allow seamless integration into any architectural palette. The refined frame depth maximises glazed area and natural light penetration.

Ideal for passive house projects, high-end renovations, and homes in temperate climates with exacting energy standards, HF310 Studio represents a long-term investment in thermal comfort, acoustic tranquility and the security of a premium living space.

A U-value of 0.71 W/(m²K) is excellent performance, meeting PassivHaus and NZEB standards—heat loss through the window is minimal, delivering significantly lower heating consumption. The wood-interior-with-aluminum-exterior design, combined with triple glazing, warm spacers, and argon gas, creates a superior thermal barrier that keeps your home comfortable in harsh winters while visibly reducing monthly energy bills.

The HF310 Studio's wood-aluminum design combines the warm, natural aesthetic of interior wood with the UV resistance and durability of an exterior aluminum profile, giving you the best of both worlds. Exterior aluminum is weather-resistant and never requires repainting, protecting the wood core from direct sun and rain damage. The interior wood can be painted any color you choose, letting you personalize your space, while the outer aluminum frame remains virtually maintenance-free and architecturally elegant over decades.

RC2 (Resistance Class 2) means the window has been tested and certified to resist break-in attempts using basic hand tools—the triple glazing and multi-point locking hardware make forced entry extremely difficult. It's the recommended standard for residential homes and suburban properties with moderate security concerns; if you live in a high-crime area or have elevated risk, you can upgrade to RC3, which offers protection against power tools as well.

Sound insulation rated Rw 33–46 dB provides substantial noise reduction; the higher value (46 dB) cuts out heavy traffic and industrial noise, while the lower range (33 dB) quiets lighter sounds like speech and moderate traffic. Triple glazing with optimized spacers and inert gases isolates far better than dual-pane systems; if you're above a busy street, a well-configured triple-pane setup transforms constant traffic roar into a subtle hum barely noticeable in quiet moments.

The Internorm HF310 Studio is fully custom-sized to your exact opening dimensions—you measure your window space precisely and order to your specifications; the window arrives pre-assembled and pre-fitted from the Austrian factory. Montage is simplified: seals are applied and the frame is screwed into place using Internorm's profile system, which dramatically reduces on-site assembly time and error margin. A specialist will help ensure your measurements account for proper leveling and drainage slopes to guarantee a perfect seal.

The interior wood of the HF310 Studio can be painted in any color from the full RAL palette or Internorm brand colors, giving you creative freedom to match your interior décor and furniture. The exterior aluminum comes in discreet standard finishes (white, aluminum gray, anthracite) but can be custom-painted or anodized on request; this lets you combine a warm interior color (say, dark walnut or warm white) with a sophisticated exterior finish (modern anthracite gray), creating elegant aesthetic contrast.

The exterior aluminum needs only occasional washing with mild soap and water to remove pollutants; the interior wood should be recoated with quality varnish or paint every 3–5 years to preserve its look and prevent moisture infiltration. Long-term concerns are mostly seal wear (gaskets can be replaced affordably) and potential water infiltration if drainage slopes aren't perfect—proper installation and regular gasket inspection are crucial to prevent decay. Argon gas in the triple glazing doesn't escape suddenly; if you notice condensation between panes, it signals that the seal has been compromised and requires professional repair.
