The SV-7800 Thermo Plus is SIVAL's highest-performing opening system, built on a 78mm frame with a 42mm multi-chamber polyamide thermal break and central gasket sealing. Accepting glazing units up to 62mm thick, it comfortably achieves whole-window U-values from 0.9 W/m²K with triple glazing — making it a natural choice for Passivhaus-inspired projects, EnerPHit retrofits and any build where energy bills matter.

Beyond the numbers, the SV-7800 delivers everyday comfort: concealed hinges carry sashes up to 160kg, multi-point locking achieves enhanced security specification, and acoustic glazing options cut street noise by up to 45dB. Typologies include side-hung casements, tilt-turn, fixed lights, low-threshold balcony doors and 90-degree corner assemblies, all finished in any RAL shade, anodised tone or textured wood-effect.
