Certified orangery
Our orangeries are built with VANSTA CLASSIC, a profile system where details and thoughtful work are in focus. Our supplier is a well-reputed company known worldwide for its high-quality aluminum building systems. Our strength lies in the aesthetic design with beautiful and thoughtful details.
Within VANSTA CLASSIC we offer a wide range of aluminum systems for windows, doors, facades, sliding systems, folding systems, conservatories, winter gardens, railings and roof systems, both insulated and non-insulated. We prioritize only systems with high insulation capacity and the best available U-values.
Our profiles are powder coated with and available in a wide range of colors, including glossy, matte, pearlescent and metallic effects. We strictly follow all technical processes according to EN standards (Qualicoat) to ensure high quality and durability.
We do not customise to standard dimensions, which allows for total integration of your conservatory with your existing house to create a unified and beautiful overall picture. Your conservatory can be built in different shapes, colours and dimensions according to your specific wishes. We take wind and snow loads into account to ensure stability and safety.

Our U-values
Our U-values are calculated with both aluminium parts and glass as a complete glazed profile. They vary in terms of how much of the surface is glazed and the choice of glass.
Roof hatches can only be made with double glazing. Functional glass with, for example, fire rating or enhanced UV protection can be ordered, as can tinted or machine-drawn glass.
- only roof with double glazing = 1.66 W/M².K
- only roof with 3-glass = 0.86 W/M².K (not including special glass)
- conservatory (walls/doors) with 2-glazing = 1.78 W/M².K
- conservatory (walls/doors) with 3-glazing = 1.48 W/M².K
- the unglazed part of the lantern roof - 0.309 W/M².K.

Load calculations
In all our projects we calculate the snow load. We start from the snow zone of the geographical location right from the start. If necessary, we can insert steel reinforcement in the profiles completely hidden from view, but it may also happen that we need additional steel reinforcement, especially in houses with a large width. As a rule, we also use tie rods in the eaves of our orangeries.
We can easily make very large buildings and special solutions.

Reinforcement with steel
In a wider doorway or in a ceiling with large spans, steel reinforcement may be needed. As a first step, we do this inside the profile and completely hidden from you, but sometimes a steel frame may be needed. We draw this in our design and, if necessary, we can include this in our delivery. All steel is surface treated and galvanized.
Vansta has resources for both private customers and larger construction projects. We design and are a competent partner in both small and large contexts. Our project management meets all the requirements of the construction industry.
