Why This System

Spectus flush sash profiles eliminate the traditional PVC sash overhang - the sash face sits level with the outer frame face. This removes the drip edge that channels water away from the frame, meaning water sheets across the full outer face and concentrates at the bottom rail drain points. The paintable surface option on Spectus flush casements allows customers to paint the outer face in any RAL colour - a common specification in conservation areas. Painted uPVC surfaces require specific cleaning care around paint compatibility. Spectus vertical slider systems replicate the look of traditional box sash windows but operate on spring balances rather than weights. The meeting rail - where the two sashes meet at the centre - is a specific cleaning challenge on vertical sliders.

Pro Tips

On Spectus flush casements, angle your squeegee pull slightly downward and outward at the end of each stroke so water clears the bottom rail rather than running across the face
Always clean both faces of the meeting rail on Spectus vertical sliders - upper face from above using a cloth over the fingers, lower face by reaching up from below
If a customer's Spectus paintable frame is a custom colour, photograph it at the first visit - you have a reference if a cleaning incident requires documentation

What NOT To Do

Do not use aggressive uPVC chemical cleaners on painted Spectus surfaces
Do not use solvent-based cleaners on any Spectus profile surface
Do not pressure wash Spectus flush sash systems - the flush face with no drip edge means high pressure forces water directly into the frame cavity
Do not force vertical slider sashes if they are stiff - check spring balance condition before applying force
Do not use abrasive pads on any Spectus profile surface

Field Notes

“Spectus flush sash windows in conservation areas are often in streets where the local planning authority is monitoring the appearance of properties. Work cleanly and avoid leaving tool marks, product runs, or ladder marks on the outer face - these are visible from the street. Meeting rails on Spectus vertical sliders are often missed entirely by non-specialist cleaners. Customers who have had previous cleaners notice when the meeting rail is properly cleaned for the first time. In UK coastal conservation areas, Spectus paintable frames with custom paint colours are common in property renovations. Check paint condition before every clean - salt air and damp cycles stress paint adhesion on uPVC.”
