Create light-filled, 4-season rooms that bring the outdoors in. Our sun rooms and winter garden systems combine bioclimatic pergola roofs with glass walls to give you a comfortable space in every season.
A sun room or winter garden is more than a pergola. It is a room-like, protected outdoor living space created by combining a fixed aluminium profiles, retractable roof and glass wall systems.
Rather than simply providing shade, these systems create a customizable enclosure. The structure is built on pergola technology and paired with a bioclimatic or glass roof, while the surrounding space is enclosed with glass walls such as fixed panels, sliding or folding doors, and in some cases guillotine windows.
The result is a space that sits between indoors and outdoors. It offers protection from the weather, fills with natural daylight, and maintains a strong visual connection to your garden, terrace, or surrounding view
Behind the transparent surfaces and slim profiles, there is careful technical thinking.
For detailed values and drawings, you can direct architects and planners to dedicated roof and glass system pages or technical resources.
Every project starts with the existing building and how you want to use the space. Impergo systems use the same pergola technology—but here, they work together as a full room system. Typical configurations include.
Our sunroom and winter garden systems offer adaptable designs to suit any architectural need. Whether attached to a building, freestanding, or wrapping around corners, each solution is tailored for optimal space, natural light, and seamless integration with the structure.
Extending a living room, kitchen, café, lobby, or office onto a terrace or garden.
A separate garden room or retreat placed within the landscape.
Enclosing existing balconies or wrapping around corner terraces for panoramic views.
Sun rooms and winter gardens are built from the same high-quality components as bioclimatic pergolas, carefully combined into one coherent system.
High-quality aluminum load-bearing frames, posts, and beams create the main structure, with integrated drainage channels to guide water through the profiles. Concealed fixing options help maintain clean lines and a refined appearance.
Choose from fixed or retractable glass roof systems, including laminated and insulated glass options designed for durability and thermal performance. Each roof system helps regulate daylight, ventilation, and rain protection, while reflective glass options can reduce UV exposure, limit heat gain, and maintain a brighter, more comfortable interior environment.
Fixed glass panels, sliding glass doors, folding glass systems, and guillotine windows can be configured with insulated or thermal glass options to improve comfort and weather protection while keeping the space bright and open.
Because these are complete rooms, the uses go far beyond simple sitting areas.
Here are a few examples of homes where outdoor areas have been transformed into comfortable four-season living spaces.
A well-designed sun room or winter garden changes how you use your home or space every day.
Enjoy a comfortable space in rain, wind, or cold days.
Sit close to the garden or terrace without feeling exposed.
Create a calm, cozy environment with natural light and shelter.
Large glass surfaces bring in daylight from multiple directions.
Bioclimatic or glass roofs maintain a strong connection to the sky.
Slim aluminium profiles preserve views of the garden, city, pool, or landscape.
In warmer months, open the roof and glass to let fresh air flow.
In cooler seasons, close everything and use heating as needed while keeping the view.
One space that adapts to mornings, evenings, and seasons—not just perfect weather

It’s a hybrid space. Technically, classification depends on local regulations and how it’s connected to the building. We can support you and your architect with technical data as needed.
Roof louvers, opening glass elements, shading, and optional heating or cooling help manage comfort. In some projects, the room is integrated with the building’s HVAC; in others, it’s treated as a semi-outdoor space.
Good ventilation and correct system design are important. We combine suitable glass, profiles, seals, and ventilation possibilities to help reduce condensation.
Yes. With retractable roofs and sliding/folding/guillotine glass, you can open large parts of the room to feel like an open terrace.
Permits depend on local rules and whether the space is considered an extension. Your municipality or local authority has the final say; we can provide technical drawings and information to support the process.
In many cases, yes—subject to structural capacity and details of the existing construction.
