Energy-Saving REHAU Windows: How to Choose Windows for an Apartment

Energy-saving REHAU windows help retain heat in an apartment: the video explains how to choose windows by profile, glass unit and hardware. Presented as advice from a specialist, it covers the key criteria for selecting a metal-plastic window.

What the video shows

• Window selection starts with the profile; five-chamber systems — REHAU Ecosol-Design and REHAU Euro-Design 70 — are named as the best balance of price and quality.


• The profile is reinforced with steel at least 1.5 mm thick.


• The insulating glass unit is a double-chamber (triple-glazed) unit with a low-emissivity coating; the chambers can be filled with argon for better thermal performance.


• The hardware provides several ventilation modes: turn, tilt and micro-ventilation.


• The quality of the finished window depends on correct installation.

These reference points make it easier to compare energy-saving window configurations and choose the right option for a specific apartment.
