WINDOWS
4/15/2025


Greta is a window designed for those who expect not only a neat design but also a real impact on the environment. This premium PVC system stands out with its elegance, functionality, and ecological approach to production.
What makes Greta unique?
Construction and appearance
Greta has a sleek profile with a depth of 82 mm, allowing the use of triple-glazed packages with widths from 24 to 52 mm – this way, the window not only looks good but also insulates perfectly. The profile features a porous surface layer – resembling architectural concrete – which makes it exceptionally stylish and pleasant to the touch.Excellent insulation and safety
Thanks to phenomenal thermal parameters (Uw of the window with the Ultimate Warm Frame package: 0.74 W/m²K), Greta helps reduce heating bills. The profile also has a five-point anti-burglary system and three seals (including a central seal), effectively protecting the interior from cold and unwanted guests.Ecology in practice
Greta is a product made of 100% recycled materials. By using recycled PVC in production, the negative impact on the environment has been reduced – while maintaining high technical parameters.Durability and sturdiness
The window meets standards for water tightness (class 8A), air permeability (class 3), and resistance to wind load (class C4)
Who is Greta the best choice for?
Greta is perfect for:
people who appreciate clean, minimalist forms in Scandinavian and industrial styles,
those who want to opt for environmentally friendly solutions — from design to installation,
users who want to brighten up their interiors without compromising on aesthetics and efficiency.
