A new SPD150 aluminium door system from Senior Architectural Systems is opening up new opportunities in the commercial market. The system has been developed to meet the demands of high-traffic environments where accessibility, performance, and durability are key. 


Developed as a non-rebated door and framing system, the SPD150 can be fabricated as single or double doors, with various configuration options such as emergency exit versions and anti-finger trap stiles. One of its key advantages is its low threshold design, which provides easier access for wheelchair users and reduces the risk of trips. 

The use of low thresholds can also contribute to a more streamlined interior design, making the new SPD150 commercial door suitable for use across a variety of sectors including healthcare, education, office schemes, and other public use buildings. For specifiers seeking a clean, modern aesthetic, the system also supports the integration of concealed closers and hardware for a minimalist appearance.  


Fully recyclable and offering enhanced thermal performance, the SPD150 door system achieves U-values as low as 1.3W/m²K when triple-glazed (CEN standard) and 1.6W/m²K when double-glazed. The system is also fully tested to meet PAS24 for enhanced security and BS6375 parts 1 and 2 for weather tightness and durability.
