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 Tools
My daily tool list. This is what I carry to every job.
Follow these steps in order. Each one builds on the last. This is the same sequence I use on every Senior Architectural Systems installation.
- 1
Preparation -- before any water touches the glass
Fill the bucket with at least 10 litres of water. Add soap for cleaning power -- enough to cut through environmental deposits, not so much you are fighting foam.
Before touching the glass, brush down the surface to remove loose dust, spiderwebs, and debris. Any grit left on the glass during the wash phase risks scratching during agitation.
Check the aluminium frame condition before you start. Confirm which cleaning product is safe for that surface before opening any bottle.
Cover anything below the windows that cannot be moved.
- 2
Agitation -- apply and work the solution
Dip the microfiber T-bar completely into the soap water, both sides. Remove excess water with your hand so it does not drip. Apply the solution across the entire glass surface with overlapping passes.
The goal is to fully dissolve and release every deposit from the glass surface. Anything not released during agitation gets transported across the glass by the squeegee as a smear.
For stubborn spots -- insect marks, salt residue, environmental deposits -- re-apply soap water and allow it to soak for a full minute before agitating again. Use more soap water, not more pressure.
For panels above arm reach: attach the T-bar to an extension pole. Work in sections -- top first, then middle, then bottom -- keeping each section wet until you squeegee it.
Rinse the T-bar cover regularly during the job. A dirty applicator causes microscopic scratches that accumulate over time.

Detail the frame edge before squeegeeing
Use your 100% cotton towelling rag, finger pressed into the fabric, to work into every junction and remove pooled soap water before the squeegee pass.
This prevents drips running down onto already-cleaned areas during squeegeeing and keeps soap water out of drainage channels.
On Senior Architectural aluminium frames, pay particular attention to the bottom edge where glass meets the frame sill -- water pooled here runs into drainage openings and leaves residue over time.
- 4
The squeegee
Tilt the squeegee at a slight angle so soap water spills from one side of the channel only -- not both. If the rubber is jumping or squeaking, either the rubber is not lubricated enough or the glass surface has warmed.
Cutting in: start with the rubber blade making first contact on a dry edge of the glass.
Side to side: horizontal passes across the panel. Works well on wide sections. Top to bottom: vertical passes down the panel. Works well on tall narrow sections.
The J tune: one smooth unbroken motion top to bottom, wrist rotating at each end to reverse without lifting the rubber. The most efficient method on larger panels -- but it requires training before applying it to premium glass.
Wipe the rubber dry after every pass. Overlap each stroke by 2-3 cm.
- 5
Final edge detailing
After squeegeeing, there is always a residual line of water along the bottom edge and at the panel sides. Take a dry cotton rag, fold to a clean corner, and detail these edges in one smooth pass.
On Senior Architectural frames, the bottom edge where glass meets the sill requires the most careful attention. Water left here runs into drainage and leaves residue that affects the next clean.
Rotate the rag to a clean section after every pass. If the rag picks up grit at any point, replace it immediately.
- 6
Frame wipe and hardware check
On Senior Architectural powder-coated aluminium frames: use pH-neutral cleaner only, never abrasive pads or steel wool. Dry immediately after wiping.
Check that all drainage openings are clear and unobstructed. Water must be able to flow freely -- a blocked channel leads to accumulation that affects seal performance over time.
Operate every opening window through its full range. Stiff handles or resistance at locking points indicate hardware that needs lubrication. Flag it to the owner rather than forcing it.
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
โSenior 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.โ
