Reliable for many building situations
Depending on the project, S 8000 is available with 5 chambers for excellent statics or with 6 chambers for good thermal insulation. The spacious main chamber takes massive steel reinforcements, so even large windows stay stable and durable. A comprehensive range of system accessories makes it easy to realise all common window and door types.
Windows
Thanks to their well-thought-out design, S 8000 profiles are a dependable basis for stable, long-lasting windows. The system combines cost-efficiency with functionality and suits both new buildings and renovations.
Front doors
S 8000 profiles also form high-quality front doors. Large steel reinforcements in the main chamber provide reliable statics, and extensive equipment options let the doors meet very different requirements while matching the windows perfectly. See Entrance doors.
Surfaces
Besides classic white, a wide range of high-quality decorative foils is available, so windows and doors can be matched to the colour and style of the building.
