Fereastră PVC-Aluminiu KF510 Home Pure — Triplu, Passivhaus

Internorm KF510 Home Pure PVC-Aluminium window with triple glazing and thermal performance of 0.64 W/(m²K), PassivHaus certified. RC3 security and superior acoustic insulation for premium comfort.

The KF510 Home Pure window from Internorm redefines the standard of comfort and energy efficiency for modern homes. Built with high-performance PVC-Aluminium profile, this window combines technical rigour with understated elegance, making it ideal for renovations and new builds demanding superior insulation.

Thermal insulation is ensured by triple glazing with optimized chambers and Uw values down to 0.64 W/(m²K), placing it in the category of Passive House windows. The integrated I-tec Secure system provides additional protection, while the PVC construction with aluminium reinforcement guarantees long-term durability without complex maintenance requirements.

Acoustic performance is remarkable, with sound insulation in the range of 34–48 dB, eliminating urban noise and protecting the privacy of your space. RC3 certification for break-in resistance offers a high level of security, making it a suitable choice for properties in higher-risk areas or for owners who prioritize protection.

The Home Pure design is abstract and adaptable, allowing integration into diverse architectural styles—from contemporary houses to historically sensitive renovations. The profiles are proportioned and discreet, keeping the view to the outside in the foreground, while robust construction remains invisible from interior perspectives.

This window is recommended for continental and oceanic climates where thermal variations are significant. Investment in a KF510 Home Pure window is justified by reduced heating costs, consistent interior comfort and increased property value over the long term.

An Uw value of 0.64 W/(m²K) is exceptionally high performance, positioning the KF510 window in the passive house and NZEB (nearly zero-energy building) category. This low value means minimal heat loss in winter and superior insulation in summer, translating to significantly lower heating and cooling bills throughout the home's lifespan. The triple glazing combined with the PVC-aluminum frame and warm spacer technology deliver this premium performance.

RC3 is the highest residential window certification level, testing resistance against brute-force attempts using hand and power tools. The KF510 Home Pure is equipped with I-tec Secure multi-point locking hardware and security glass that protects against break-in attempts with pry bars, screwdrivers, or hammers—common burglary methods. This certification is especially valuable for properties in urban areas or for homeowners prioritizing maximum peace of mind.

Triple glazing provides approximately 20–30% better thermal insulation than double glazing and, more importantly, significantly reduces ambient noise. The KF510 achieves acoustic insulation of Rw 34–48 dB, meaning traffic, neighbors, and construction noise are barely noticeable from outside. Each glass pane and warm spacer between them absorb sound vibrations, delivering acoustic comfort that premium homeowners appreciate, especially in high-traffic areas or near commercial zones.

The PVC-aluminum combination offers the best balance between thermal performance, durability, and architectural aesthetics. The interior PVC ensures exceptional thermal insulation and minimal maintenance, while the exterior aluminum layer protects against UV rays and weather exposure, maintaining an elegant appearance long-term. The KF510 Home Pure benefits from this premium combination for clients seeking modern comfort without compromising on premium finishes, whether the home has a traditional or contemporary style.

The KF510 Home Pure is manufactured to custom specifications matching your exact window openings, eliminating on-site adjustments that could compromise thermal and acoustic performance. Internorm recommends installation by certified specialists who ensure proper sealing, frame positioning, and polyurethane foam filling according to standards—all essential steps to achieve the guaranteed insulation and security values. The process takes 3–4 hours per window and requires no structural wall modifications.

Internorm's PVC is UV-resistant and requires no painting or periodic treatments—just cleaning with water and neutral detergent twice yearly. The I-tec Secure hardware may need light lubrication of pivot points once annually, and the drainage slot at the base must stay clear of debris. After 10–20 years, PVC profiles remain functional and aesthetically pleasing without material degradation; triple glazing won't condense on the interior due to minimal temperature differences between panes, and sealing can last up to 30 years thanks to the high-quality warm spacer.
