Why This System
Senior's PURe foam thermal break is invisible from the outside but changes the internal profile geometry. From a cleaning perspective, the profile surface is standard powder-coated aluminium - the PURe technology is entirely internal. Senior's slim sightline residential systems are increasingly specified in premium UK housing where the brief calls for narrow aluminium frames and large glass areas. The slim frame means less frame surface to clean but more glass - squeegee technique matters more. Senior systems appear in demanding UK public sector buildings - schools and healthcare - where cleaning frequency, COSHH compliance, and product safety documentation are often contractual requirements.

The Orloffs Protocol
This is how I clean Senior Architectural Systems windows. The tools and technique below come from 25 years of daily professional work on the glass. Every step has been tested on real installations and adapted specifically for Senior Architectural Systems systems.

Pro Tips
- Match your squeegee width to the glass panel on Senior systems - using a narrow squeegee on large curtain wall panels increases stroke count and line risk
- On Senior school and healthcare buildings, have your COSHH sheets ready before the first visit - the facilities manager will often ask for them
- Senior PURe slide lift-and-slide doors are heavy - the sash weight means the lift mechanism is under stress if the track is contaminated with grit. Clean tracks at every visit, not just annually
What NOT To Do
- Do not use abrasive pads on Senior powder-coated aluminium frames
- Do not use alkaline or acid cleaners on powder-coated surfaces
- Do not pressure wash into Senior curtain wall glazing bar joints
- Do not lubricate the compression seal on lift-and-slide door tracks - seal lubricant causes the seal to fail
- Do not use chemical products not listed on your COSHH sheet on public sector Senior buildings

Frequently Asked Questions
Field Notes
“Senior systems in Yorkshire and the North of England are subject to some of the heaviest rainfall in the UK. Drainage slot maintenance on Senior casement and curtain wall systems is more critical in these locations than in drier southern counties. On UK school buildings with Senior systems, cleaning visits often need to be scheduled outside term time for full access. Plan around the school calendar when quoting and scheduling. Senior slim sightline residential windows on premium new-build are often paired with solar control or self-cleaning glass coatings. Confirm glass coating type with the building owner before using any chemical cleaning product.”
