The Gutmann S70+ Window System is a premium architectural window solution, engineered for superior energy efficiency, durability, and modern aesthetics. Crafted to meet evolving building codes and sustainability standards, this system delivers superior thermal performance with minimized heat transfer and sleek contemporary styling—ideal for both commercial and residential applications.
Versatile Window Types
The S70+ system offers multiple operation styles to suit design needs:
-
Out-swing & In-swing Casement – Clear opening operation with tight sealing and robust performance—casements are known for low air leakage and excellent natural ventilation control.
-
Dual-Action Tilt/Turn – Designed for improved airflow and easy maintenance, with versatile tilt-in and turn-in functions.
-
Top-Hung Project-Out Awning – Provides reliable protection from rain while enhancing airflow.
High-Performance Construction
This system employs a 2¾″ (70 mm) profile depth, allowing for triple insulating glazing units (IGUs) to optimize comfort and energy control. IGUs with multiple panes, inert gas fills (like argon), and low‑E coatings significantly increase insulation while reducing heat gain and UV exposure.
Key features include:
-
Thermally broken frames with polyamide and foam core insulation to minimize conductive heat flow.
-
Warm-edge spacers to reduce edge condensation and enhance overall seal performance.
-
Energy performance metrics such as low U‑Factor and Solar Heat Gain Coefficient (SHGC) help specify the system for climate-appropriate installations
Tested To:
- ASTM E330
- ASTM E283
- ASTM E331
