The robust choice in opening systems for enhanced thermal insulation!
Robust construction. Impressive thermal insulation coefficients. Modern aesthetics. In short, a triple advantage solution with the SV-7800 Thermo Plus system, the latest system from SIVAL in opening aluminum architectural systems with 42mm polyamide. Fans of both modern and classic lines will be equally satisfied, as the product is available in profiles with either a straight line for modern aesthetics or a curved line that references the classic style.
An important feature is the option to install a multilocking mechanism, providing greater security for the space.
The profile design with a hidden sash offers a minimal aesthetic result in window applications.
Special profiles also allow for the construction of entrance doors.






Figures depend on configuration, size and glazing — your quotation includes values calculated for your exact specification.
Every SIVAL system is finished to order: powder coating in any RAL shade (matt, satin or gloss), anodised tones, and textured wood-effect finishes including oak, walnut and rosewood. Dual-colour options let the interior differ from the exterior, and marine-grade pre-treatment is available for coastal sites. Powder-coated finishes are guaranteed for up to 25 years.
