Fereastră PVC-ALUMINIU KF310 Home Soft — Triplu, Passivhaus

Internorm KF310 Home Soft PVC-ALUMINIUM window: hybrid profile with triple glazing, PassivHaus-certified and Uw 0.69 W/(m²K) thermal performance for energy-efficient modern homes.

The KF310 Home Soft series represents Internorm's hybrid window solution for homeowners seeking the perfect balance between contemporary aesthetics and superior energy performance. The PVC-ALUMINIUM profile combines the thermal insulation of plastic with the durability and elegance of exterior aluminium, making it ideal for renovations and new constructions across temperate to continental climates.

The triple low-e glazing construction features three sealed air chambers and specially treated glass, delivering thermal insulation down to Uw 0.69 W/(m²K). This value places the window in the passive building category, enabling significant heating energy savings. Acoustic insulation of Rw 33–45 dB ensures effective attenuation of external noise, transforming interior spaces into quiet sanctuaries.

Classified RC2 for security, the KF310 Home Soft resists forced entry and offers enhanced protection against break-ins. The hybrid profile is engineered to withstand wind pressure and water infiltration to the strictest standards, ensuring long-term durability without compromise. Its robust construction guarantees reliable performance across decades of use.

The clean, geometric design of the Home Soft series integrates seamlessly into contemporary architecture, whether in a minimalist home or a traditional renovation. The profile allows optimal light transmission and does not dominate visual perspective, making it an ideal choice for residences that prioritise proportions and refinement.

KF310 is recommended for passive houses, energy-efficient renovations and any project where thermal performance and acoustic comfort are priorities. Austrian manufacturing by Internorm guarantees quality and reliability for generations.

The hybrid structure combines PVC's superior thermal insulation with aluminium's UV protection and durability on the exterior face. This ensures exceptional weather resistance and climate durability while maintaining long-term energy efficiency, without requiring regular repainting.

Yes, the KF310 profile is PassivHaus certified with thermal performance of Uw 0,69 W/(m²K), meeting international standards for passive houses and nearly-zero energy buildings (NZEB). Triple glazing and warm-edge spacers ensure minimal thermal losses.

The KF310 window provides sound insulation with Rw index ranging from 33–45 dB, depending on the selected glazing configuration. Triple glazing with insulating gases (argon/krypton) and the dense profile significantly reduce external noise transmission, offering optimal acoustic comfort even in busy urban areas.

The KF310 is available in multiple color finishes and complementary profiles to match any building style, from modern homes to classic renovations. The aluminium exterior allows sophisticated architectural customization, including special handles and integrated solar protection systems. Bespoke installation ensures exact dimensions for each structure.

RC2 certification ensures resistance against break-in attempts using simple manual and mechanical tools, providing robust protection for standard residential properties. Multi-point hardware and reinforced triple glazing guarantee a secure structure that resists conventional break-in attempts, offering homeowners peace of mind.

The PVC-aluminium profile requires minimal maintenance: periodic cleaning with mild soap and water, without need for repainting. The exterior aluminium is treated for UV resistance lasting 20-30 years, and the triple glazing with insulating gas and warm-edge spacer maintains constant thermal performance. Multi-point hardware should be adjusted periodically for optimal operation.
