What Makes Our Windows Special
Our fachwerk houses use triple energy-efficient anti-vandal glazing — designed for maximum thermal insulation, security, and aesthetics. The glass unit is a core component of our homes' A+ energy rating.
- Triple glazing unit with a total thickness of 52 mm
- Tempered anti-vandal glass — impact-resistant
- Special "4 Seasons" coating of silver and metal layers
But the most important element is what lies inside those 52 mm — and how the "4 Seasons" coating works.
"4 Seasons" Coating — How It Works
The "Four Seasons" coating is a multi-layer application of silver and metals deposited on the glass surface. It operates on the principle of a smart thermos — simultaneously reflecting and retaining heat.
The coating reflects up to 60% of solar infrared radiation. The room heats up more slowly, and air conditioning costs fall significantly.
The coating acts as a mirror for thermal waves from heaters and radiators — reflecting them back into the room and preventing heat loss to the outside.
Combined with argon and xenon (a gas that retains heat significantly better than argon), the "4 Seasons" coating makes the glass unit extraordinarily energy-efficient.
Technical Specifications of the Glazing
Our triple-glazed window unit combines several technologies for maximum thermal protection:
- Thickness of 52 mm — considerably deeper than the standard 24–36 mm units
- Argon and xenon gas fill — xenon retains heat many times better than air
- Tempered glass — anti-vandal, resistant to mechanical stress and impact
- "4 Seasons" coating — a silver-based layer reflecting infrared radiation
Comparison with a Brick Wall
To understand the thermal insulation potential of our glass unit, we compare it with brick masonry. In thermal terms, it is equivalent to the following wall thicknesses:
| Type of masonry | Equivalent thickness |
|---|---|
| Solid silicate (white) brick masonry | 110–120 cm (4–4.5 bricks) |
| Solid ordinary red (clay) brick | 90–100 cm (≈ 4 bricks) |
| Hollow (efficient) brick | 50–60 cm (2–2.5 bricks) |
Summary: In its ability to retain heat, our glass unit equals a solid brick wall one metre thick. By the standards of the window industry — this is a "cosmic" level of thermal performance.
What This Means for Your Home
These technical parameters translate into real everyday comfort and savings:
- Lower heating bills — less heat escapes to the outside
- A more comfortable summer — less solar heat enters the interior
- Panoramic glazing is not a compromise — it is a thermal advantage when the glass performs correctly
