A modern, premium-class window system in the EKOSOL range, based on the renowned Kömmerling 88 MD profile. Created with modern construction in mind, it combines excellent technical parameters with minimalist aesthetics and a high standard of craftsmanship.
This system stands out with an increased construction depth of 88 mm, which translates into excellent thermal insulation and structural static properties. Thanks to this, SOLPREMIUM is perfect for both energy-efficient and passive houses, offering a window thermal transmittance coefficient as low as Uw ≤ 0,72 W/m²K (depending on the glazing unit used).
The system has been designed with durability and ecology in mind – the profile is 100% lead-free, and the Greenline base material aligns with the philosophy of sustainable construction. Optional composite fiber reinforcements or “Bonding Inside” technology (glass bonding) ensure even greater structural stability and more design freedom, even in the case of large-scale glazing.
A distinctive, modern design combined with a wide range of exclusive foils – including metallic and wood-like finishes – ensures that the SOLPREMIUM system perfectly fits the soft-industrial aesthetic and modern, geometric facades.
SOLPREMIUM is an intelligent fusion of form, technology, and environmental responsibility – the ideal solution for demanding investors who refuse to compromise.
- 7-chamber frame and sash profile with an 88mm construction depth.
- MD profile system featuring a center seal (middle gasket).
- Slender profiles available in non-recessed (offset) sash variants.
- Foam Inside System – a proprietary design involving the injection of polyurethane foam into the profile chambers, improving the window’s thermal performance by up to 20% (optional).
- Bonding Inside – a proprietary design featuring perimeter glass bonding. This technique allows for significantly larger structures while reducing adjustment maintenance to a minimum (optional).
- The system perfectly aligns with passive housing trends.
