PRODUCT DESCRIPTIONPLANITHERM® 4S (II) and PLANITHERM® 4S EVOLUTION are solar control glasses designed for window use in hot climates (South and South‑East Europe). Positioned as summer‑comfort glazing, they balance solar control and year‑round thermal performance in double glazing.
BENEFITS & APPLICATIONSRecommended for double‑glazed windows in residential and tertiary buildings (schools, hospitals, offices) in warm climates. They reduce overheating in summer while maintaining improved insulation in winter, helping lower energy demand for cooling and heating.
- Summer comfort: Significantly reduces internal overheating. Solar factor g = 0.42, blocking about 58% of solar energy.
- Winter comfort: Low‑emissivity coating increases thermal insulation in double glazing (Ug ≈ 1.0 W/m²K).
- Visual comfort: Limits excessive solar gain so external shading (blinds, curtains) is less often required, preserving daylight and external views.
APPEARANCEThe coating has a neutral aesthetic, making it suitable for architectural window applications where transparency and color neutrality are required.
TECHNICAL INFORMATION- Range / Substrate: Substrate = PLANICLEAR® (clear glass).
- Thickness: 4 mm and 6 mm (other thicknesses and laminated options available on request).
- Size: Jumbo 3.21 x 6.00 m; standard stock sizes available; custom split lengths on demand.
- Availability: Produced and available in Spain and Romania.
PROCESSINGCan be processed like a standard low‑e coating. Processing options include:
- Annealed: product available annealed.
- Heat treatment: available to‑be‑tempered (suffix II).
- Insulated glazing unit (IGU): must be assembled into an IGU with the coating facing the cavity (inner face).
- Lamination: laminatable; when laminated place coating on face 4 (outside of the laminate).
- Enamelling: no general approval for enamelling silver‑based high‑performance coatings.
- Laminated variants: available for safety (STADIP® PROTECT) or acoustic insulation (STADIP® SILENCE).
PERFORMANCEKey performance: solar factor g = 0.42 (≈58% solar energy blocked); low‑e performance enabling Ug ≈ 1.0 W/m²K in double glazing. Additional configurations and performance charts are available from the manufacturer's technical documentation.
