What materials should you choose for a conservatory?
-
Generally, the materials used to design a conservatory are aluminum, wood, PVC, and steel. A guarantee of quality and durability, aluminum is the most recommended and most popular material for this type of structure. In fact, it requires less maintenance than wood and does not rust, which avoids the need to undertake major maintenance work.
Aluminum is also known to be much stronger than other solutions, especially when weather conditions become difficult. The latter is easily resistant to snow, and to periods when the winds blow very intensively. Lightweight, aluminum also makes it possible to create completely custom conservatories. Its design allows you to choose between several colors so that the structure adapts to the style of your home.
In terms of insulation, Akena offers insulating roofs in order to guarantee thermal comfort inside the conservatory. Double glazing also makes it possible to maintain a pleasant temperature, and a breathable atmosphere, regardless of the season. Using high-performance glazing can also help reduce your dependence on air conditioning or heating.

Are you considering installing a bioclimatic conservatory to enjoy a bright and pleasant living space all year round? But what is the price of a bioclimatic conservatory?
The average price of a bioclimatic conservatory in France depends on many factors. In general, the cost can vary between €1,250 and €3,000 per square meter. This amount includes material costs, comfort options, various amenities, and installation fees. For a standard project of 20m², the price can vary between €16,000 and €75,000 depending on the specificities chosen. It is important to note that these rates are based on averages and may vary depending on the specifics of each project.
Indeed, each bioclimatic conservatory is unique and meets specific needs. Design, material, and equipment choices can influence the final cost. For example, a bioclimatic conservatory with high-end options, such as built-in shutters or LED lighting, will have a higher cost. In addition, the complexity of the installation may also affect the price.
Several factors influence the final cost of a bioclimatic conservatory:
- The size of the conservatory: the bigger your conservatory is, the more expensive the cost will be. Each additional square meter requires more materials and more work.
- The options chosen: an integrated lighting system, temperature sensors, automatic blinds... so many options that can increase the cost of your bioclimatic aluminum conservatory.
- The level of personalization: at AKENA, each conservatory is custom designed to meet your unique aspirations. The more personalized your project is, the more the cost can increase.
