SAS 900

The SAS 900 Polynode is a nodal ceiling system designed to create multi-faceted metal ceilings. It suits complex architectural environments where ceiling forms vary. Its triangular tiles and adjustable grid allow smooth transitions from ceiling to wall, making it ideal for contemporary commercial interiors.

Tiles are suspended from two node points using torsion springs. For access, release one corner spring and the tile will hinge downward on the remaining two. You can also fully remove tiles for clear access to services above the ceiling. This makes maintenance fast and practical.

It uses an EMAC grid with threaded rods and node plates. Each node allows ±125mm height adjustment, which shapes the ceiling surface. This flexibility helps create geometric or flowing ceiling designs using standard parts.

Yes, tiles can be manufactured with openings for lighting, sprinklers and other mechanical or electrical services. If the load exceeds 2kg, use independent suspension to avoid stress on the tiles. Some applications may also require added stiffeners for central fixtures. Speak with the technical team to ensure the setup is right for your project.

Each tile comes with a 16mm acoustic pad made of high-density (80kg/m³) mineral wool, finished with a black tissue face and foil backing. This improves sound absorption in large or open areas. Alternative acoustic options are available depending on the project’s requirements.

SAS 900 tiles are triangular, with each side typically measuring 980mm. Custom tiles range from 280mm to 1280mm per side. The system weighs approximately 10kg per square metre, which is important for structural load planning.

Standard finishes include RAL 9003 and polyester powder coat. Other RAL colours are available, along with anti-microbial coatings for hygiene-sensitive areas. Specialist finishes can be provided on request to match design specifications.

Yes, the system can support both standard and complex shapes. The basic version uses uniform tiles to keep costs low. Advanced versions use curved grids and varied tile sizes for more intricate layouts. The SAS Special Projects team can also help with fully bespoke ceiling designs, including 3D surface mapping and support from concept to completion.

With proper installation and use, SAS 900 has a life expectancy of over 25 years. It’s a durable, long-term ceiling solution for commercial and institutional environments.

Three options are available. The standard system is cost-effective, using one tile size with a flat grid. The advanced system adds curved grids and varied tiles for more creative applications. For unique geometries or feature ceilings, the bespoke service offers full design support and custom configurations.
