KS 430 PVC/ALUMINIU

The KS 430 combines robust PVC/aluminum construction with exceptional thermal performance. A premium choice for modern homes demanding stability and energy efficiency.

The KS 430 series by Internorm represents a dedicated evolution for clients who appreciate the combination of durability and superior thermal performance. Manufactured in Austria, this window integrates PVC/aluminum technology — a hybrid solution that delivers structural stability over decades, resistance to weather exposure, and a premium aesthetic suited to any modern architectural style.

The KS 430's PVC/aluminum system features a five-chamber profile, engineered to distribute thermal and mechanical stresses uniformly. Triple glazing with noble gases ensures excellent thermal insulation, with competitive Uw values in its class. The aluminum cladding on the exterior is far more than aesthetic finishing — it protects the PVC core and significantly extends the window's lifespan in aggressive urban or coastal environments.

Thermal performance is anchored by rigid construction that minimizes heat loss and reduces air infiltration. The integrated drainage and ventilation system within the profile ensures that condensation and rainwater are efficiently evacuated, protecting closure mechanisms. Combined tightness with acoustic insulation makes KS 430 ideal for urban locations or properties near busy roads, where both tranquility and thermal comfort are non-negotiable.

The finish palette offers architectural flexibility — exterior aluminum can be adapted to various RAL colors, while the interior remains open for paint or wood finishing. Profiles are available in standard and custom opening configurations, enabling integration into both heritage renovation and contemporary construction. The profile thickness ensures substantial visual presence, suited to generous proportions.

KS 430 is the practical choice for homeowners investing in stability across decades. Internorm's PVC/aluminum combination delivers energy efficiency without compromising durability — ideal for regions with strong winds, extreme temperature swings, or prolonged solar exposure.

An Uw rating of 0.76 W/(m²K) places the KS 430 among top-tier solutions for NZEB and passive houses, dramatically reducing heat loss through frame and glass. This exceptional performance, achieved through the warm-edge intercalar and triple glazing, translates into lower heating bills and consistently warm interior surfaces, even during harsh winters.

RC2 certification confirms the window has passed rigorous testing against manual tools and brute force, making it suitable for residential properties with moderate security needs. The solid PVC-aluminum construction, combined with multi-point locking hardware and triple glazing, creates a substantial deterrent. While not a substitute for alarms, it provides valuable time and resistance against typical intrusion attempts.

The lift & slide system lets you gently lift the moving panel, then glide it horizontally with minimal friction—ideal for openings up to 3 meters. The integrated flush threshold (nearly 0 cm) eliminates obstacles and creates a seamless interior-exterior transition, perfect for modern homes, terraces, and open living spaces. The gliding is remarkably smooth even with thick triple glazing.

Rw 30–38 dB (varying with glazing specification) delivers substantial noise reduction from traffic, aircraft, and construction—cutting sound levels by 30–38 decibels. To put it in perspective, heavy traffic (80 dB) becomes a quiet murmur (42–50 dB) indoors. The triple glazing with warm-edge intercalar, plus optional asymmetric panes, further enhances acoustic performance in challenging noise environments.

The exterior aluminum provides superior UV protection and structural rigidity, preventing warping or bowing over decades even in hot climates or strong winds. The inner PVC core maintains optimal thermal insulation and flexibility, minimizing thermal stress cracks. This hybrid design, engineered by Internorm, ensures architectural stability and durability for 50+ years with minimal maintenance—no repainting or periodic treatments needed.

The KS 430 is fully custom-manufactured to exact opening specifications without standard size limitations. Professional installation by a certified technician is essential, adhering to NZEB standards and acoustic sealing protocols, with careful attention to masonry quality and drainage. Internorm provides technical support for dimensioning and detailed installation guides, ensuring promised performance (thermal, acoustic, lift & slide) is fully realized on-site.
