When it comes to creating sleek and uniform facades, the new mullion drained SF52 curtain wall system from Senior Architectural Systems provides the ideal solution.

Offering invisible drainage, Senior’s SF52 mullion drained system has a specially designed drainage spout, which only needs to be used above splice joints.  By enabling the system to drain through the vertical pressure plate, there is no drainage required on transoms.

By removing the need for visible drainage slots, coupled with the system’s exceptionally slim sight lines, the mullion drained option offers even greater flexibility with the ability to be faceted to 20° – 10° degrees per side – without the need for additional adaptors. Ideally suited a wide range of applications, the system can also offer ease and speed of installation.

The mullion drained SF52 is constructed using step cut transoms, which are sealed against an end seal placed into the mullion. The cut can be easily performed using a punch tool available from Senior Architectural Systems which allows the system to be installed without the need for sealing transom mullion joints.

The new SF52 mullion drained system is fully compatible with Senior’s portfolio of windows and doors and is also capable of holding double or triple glazed units ranging from 28mm to 52mm in thickness.

Interest in Senior’s thermally enhanced SF52 system has continued to soar following the product’s official launch in 2015, with SF52 now firmly established as Senior’s most popular curtain wall solution. Available as capped, silicone sealed or as a combination of the two for even greater design flexibility, SF52 has been carefully designed and developed to ensure that high aesthetics are equally matched by consistent and reliable construction quality, with no special machinery or tooling required for ease of fabrication.  Suitable for ground floor or high rise projects, full design support and technical back-up is available and the range is also available via the NBS National Building Modelling (BIM) Library.

Fully tested to CWCT sequence B and BS EN 13830 and with excellent weather performance, SF52 is also durable, recyclable and has a life expectancy of more than 40 years.
