Why This System
Security-grade uPVC with steel reinforcement is heavier than standard profiles - the sash weight loading on hinges and rollers is higher, and hardware maintenance is more critical. Multi-point locking hardware on security windows has more exposed metal components than standard single-point locks - each lock point is a potential corrosion and grime accumulation site in tropical conditions. Laminated glass has a visible interlayer at the glass edge - this interlayer is moisture-sensitive and any water ingress at the glass seal causes interlayer delamination. Edge seal inspection at every clean is essential.
Step 1 of 2: Manufacturer Recommendations
Official Care Guidance
Source: ORLOFFS PROFESSIONAL GUIDANCE - SECURITY uPVC PROTOCOL
Glass - Standard and Laminated
- Standard glass: pH-neutral solution, squeegee top to bottom. Standard technique.
- Laminated glass: same cleaning approach but inspect the edge seal at every clean. Report any discolouration, bubbling, or seal breakdown at the glass perimeter.
- Do not allow water to pool at the base of the frame - it sits against the glass edge seal and accelerates seal failure.
uPVC Frames
- pH-neutral, solvent-free cleaner on all uPVC surfaces. Microfibre cloth or soft sponge.
- Do not use citrus oil products, solvent cleaners, or abrasive pads on uPVC.
- Rinse thoroughly - solution residue on uPVC in tropical sun accelerates UV degradation.
Security Hardware
- Wipe all exposed lock hardware with a damp cloth and dry immediately - tropical humidity accelerates hardware corrosion.
- Check all lock points for clean engagement. Debris in keeper recesses is common and prevents full lock engagement.
- Apply a small amount of graphite or PTFE lubricant to lock points annually - not oil, which attracts dust.
Step 2 of 2: The Orloffs Protocol
The Orloffs Protocol
This is how I clean Sapphire Windows & Doors 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 Sapphire Windows & Doors 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 Sapphire Windows & Doors installation.
- 1
Security system check
Operate all windows through full range and test each lock point before cleaning begins.
- 2
Pre-rinse
Rinse all glass and frames with clean water.
- 3
Glass clean
pH-neutral solution, squeegee. Check laminated glass edge seals at finish.
- 4
uPVC frame clean
pH-neutral, solvent-free solution on all uPVC surfaces. Rinse thoroughly.
- 5
Hardware maintenance
Clean lock keeper recesses, apply PTFE lubricant, operate all lock points to confirm engagement.
Pro Tips
- On security-window properties, leave a written visit note confirming lock points are functioning correctly - it adds value and protects you if a post-visit security issue is raised
- Laminated glass on security windows is heavier than standard panes - casement hinges carry more weight. Check hinge alignment is correct before and after cleaning on heavy casement configurations
What NOT To Do
- Do not use solvent, citrus oil, or alkaline cleaners on uPVC frames
- Do not allow water to pool at the glass edge seal base - it accelerates laminated glass seal failure
- Do not ignore discolouration at the glass edge on laminated units - report it immediately
- Do not use abrasive pads on uPVC or security hardware finishes

Field Notes
“Security windows are premium-ticket items for the homeowner. Presenting a professional approach that includes hardware inspection and documentation builds significant trust and repeat business. On properties where Sapphire windows are the primary security measure, the homeowner is unusually attentive to window condition. Your standard of finish needs to be high.”
