SDL Avantgarde
Warming wood inside & modern aluminium outside
SDL Avantgarde wintergarden
Bringing you closer to nature
The SDL Avantgarde, with a roof pitch from 5° to 45°, will bring you closer to nature in two ways: via the natural wood on the inside and the great views to outside, bringing that outdoor feeling to your space whilst still being protected from the weather.
You can have a bespoke, highly efficient, thermally insulated glazed extension which suits the style of your home or commercial property, and with your choice of ventilation, heating, lighting and automation it will provide the perfect space.
Furniture-quality laminated timber surfaces inside give the room a warm, natural character, while aluminium covers outside in any RAL colour protect the timber and match the building exactly.
