Fereastră PVC KF410 Home Pure — Triplu, Passivhaus

Internorm KF410 Home Pure delivers exceptional thermal insulation (Uw 0.62 W/m²K) with PassivHaus certification, triple glazing, and acoustic protection up to 47 dB for ultimate comfort.

The KF410 Home Pure is Internorm's premium PVC window system setting new standards for energy efficiency and residential comfort. The pure PVC profile, available in classic white or weather-resistant aluminium-clad finish, guarantees discreet and contemporary architectural integration. The Home Pure collection is engineered for homeowners who demand uncompromising performance and long-term durability.

The multi-chamber profile and triple glazing deliver thermal insulation values up to Uw 0.62 W/(m²K), with optimised frame density ensuring superior structural rigidity. Multiple rubber gaskets stabilise thermal flux, maintaining stable interior air conditions and minimising heat loss cycles. The triple low-e glass configuration is tunable for regions with severe winters, reflecting interior warmth whilst reducing radiative losses.

Acoustic performance is outstanding — KF410 Home Pure achieves sound insulation ratings between 34 and 47 dB, making it suitable for homes in moderate to high-traffic zones. PassivHaus certification confirms compliance with passive house standards, whilst the RC2 anti-burglary rating provides additional security against forced entry attempts. Water resistance and wind penetration are tested to European standards, ensuring airtight performance throughout the window's lifespan.

The discreet profile design enables seamless integration into diverse architectural contexts, from heritage renovations to contemporary builds. Colour and surface treatment options—standard white or aluminium-clad—provide flexibility in matching façade colour schemes. Glazing dimensions and configurations are fully customisable, allowing optimisation for solar orientation and specific climate requirements.

KF410 Home Pure is the ideal choice for energy renovation projects, passive houses, and new builds where thermal performance and acoustic comfort are paramount. Manufactured in Austria, Internorm guarantees quality execution and durability across the entire service life. Investment in this calibre of window translates to reduced heating consumption and superior interior climate for decades.

The Uw coefficient measures how well the window insulates: lower values mean less heat loss. At 0.62 W/(m²K), the KF410 Home Pure is certified for passive houses and nearly zero-energy buildings, so you'll save significantly on heating and won't feel cold drafts around the frame.

Triple glazing provides three insulation layers instead of two, significantly reducing heat loss and external noise. In the KF410 Home Pure, the extra layers are filled with argon or krypton gas and warm spacers, creating a superior thermal barrier – essential for passive houses and exceptional acoustic comfort (up to 47 dB protection).

The KF410 Home Pure has RC2 certification, meaning it resists break-in attempts with simple hand tools (screwdriver, hammer). It features multi-point hardware with a multi-position locking system that distributes force across the entire frame, not just at corners. For higher-risk situations, you can upgrade to RC3 when ordering.

The KF410 Home Pure offers acoustic protection with an Rw index of 34–47 dB, depending on glazing configuration and options. At 47 dB, the window reduces noise by roughly 50% (a busy street sounds like moderate traffic indoors). The combination of triple glazing, special spacers, and solid PVC profiles creates an effective acoustic barrier.

The KF410 Home Pure is ordered to exact dimensions after precise opening measurement – you can choose profile material (pure PVC, PVC-aluminium for exterior), colors, and security options (including RC3 upgrade). Installation is handled by certified specialists ensuring perfect sealing, polyurethane foam mounting, and pressure testing. The process typically takes 2–4 weeks from order to delivery.

The KF410 Home Pure's PVC frame requires simple maintenance: wash with mild soap and water twice yearly, and inspect seals annually. The PVC profile is UV-resistant and never needs painting or treatment, unlike wood; the multi-point hardware may need light lubrication with lanolin once yearly. With proper care, the window lasts 40–50 years or more, with only minor gasket replacements over time.
