Key advantages
- Planitherm 4S Evolution — Ug = 0.5 W/m²K, 4 Seasons (4S) — the highest-performance insulating glass in the SGG range, exceeding Passive House standards
- Planistar SUN — combines thermal protection (Ug = 1.0 W/m²K double) with solar control (g = 0.27–0.60) for south/west facades exposed to summer overheating
- Stadip SILENCE — laminated glass with acoustic PVB film, Rw = 44–52 dB, the solution for homes exposed to urban traffic, railways or industrial areas
- Complete SGG range — single supplier for all requirements: thermal, solar, acoustic, security, compatible with any profile
- French product Saint-Gobain — one of the world's largest glass manufacturers, EN 1279 standards, production warranty
- Included in Neofort BIZ window — SGG glass with Warm Edge is part of the standard delivery
Saint-Gobain SGG insulating glass represents the quality standard that Neofort BIZ uses in all delivered windows, covering the full range of thermal, solar and acoustic requirements. The Planitherm range is structured in 3 performance levels: Planitherm XN (Ug = 1.0 W/m²K, double glazing, economic solution), Planitherm ONE (Ug = 0.7 W/m²K, triple glazing, nZEB standard) and Planitherm 4S Evolution (Ug = 0.5 W/m²K, 4 Seasons, Passive House standard). Planistar SUN combines the thermal function with solar control, offering transparency factors g from 0.27 (maximum solar protection, ideal for south facades) to 0.60 (high transparency with thermal insulation), and is recommended for any window with south or west orientation where summer overheating can reduce thermal comfort. Stadip SILENCE with special acoustic PVB film achieves Rw = 44–52 dB, significantly exceeding a standard glass (Rw ≈ 28–32 dB) and is essential for homes located in high noise areas. All SGG glass is produced according to EN 1279 with Warm Edge spacer and argon gas, included in the Neofort BIZ standard window price.
