How to Clean Sky-Frame Windows: Professional Glass Care
Sky-Frame windows are floor-to-ceiling frameless sliding glass panels, some up to 4 metres high. They require a specific cleaning approach for premium results.
View Sky-Framein the Encyclopedia →Sky-Frame windows are unlike anything else on the market. Floor-to-ceiling frameless sliding glass panels, some up to 4 metres high, that blur the boundary between indoor and outdoor space. Swiss-engineered, minimalist, and genuinely beautiful.
They're also a unique cleaning challenge. As an Orloff's Window Cleaning Training partner with Sky-Frame, I've worked with these systems extensively.
Why Sky-Frame Requires Special Attention
The scale. Sky-Frame panels can be enormous, up to 4 metres high and individual panels of 90 square feet.
The coatings. Many installations include low-E coatings, solar protection layers, or other specialised glass treatments.
The track system. Sky-Frame's sill track and drainage systems need maintenance.
What Sky-Frame Recommends
Sky-Frame's user manual lays out a clear 7-step process:
- Clean panes of glass with a soft cloth and a normal commercial glass cleaner.
- Remove soiling from base profile with a vacuum cleaner.
- Clean base profile with a damp cloth.
- Check the gutter for soiling.
- Ensure water can flow away in the gutter.
- Remove all tools and materials from the working area.
- Clean working area.
Sky-Frame warns: never use metal blades or glass scrapers, no abrasive material, never use solvents or alkalis, and high pressure washing is not recommended.
The Professional Technique for Sky-Frame Glass
Agitation: The Step Most People Skip
Dip your T-bar applicator into the soap water, both sides. Apply to the glass. The whole area needs to be covered entirely. Agitate the dirt to dissolve it.
On Sky-Frame's large panels, any dirt not fully loosened becomes a visible streak magnified across metres of glass.
For panels taller than arm's reach, attach the T-bar to an extension pole. Work in sections: top first, then middle, then bottom.
The Squeegee
Tilt the squeegee at a slight angle so the soap water spills out of only one side of the channel.
On Sky-Frame panels, the side-to-side turn works well for wide panels, and the top-to-bottom turn for tall narrow sections.
Wipe the squeegee rubber dry after each pass. Keep the overlap as small as possible.
Track and Drainage Maintenance
At every cleaning, vacuum or brush out the sill track. Check that drainage openings are clear.
Gaskets and Seals
Sky-Frame's seals are treated with silicone from the factory. When protection deteriorates, spray silicone spray onto a cloth (not directly on seals), then apply.
Road Salt Warning
Road salt can damage the sliding windows. Clean any salt residue promptly.
Cleaning Frequency
Minimum: Twice per year. Recommended: Four times per year for urban locations. After construction: Clean immediately.
What NOT to Do
- NEVER use metal blades or glass scrapers.
- Do not use abrasive or scouring material.
- Never use solvents or alkalis.
- High pressure washing is not recommended.
- Never clean in direct sunlight.
Why Professional Technique Matters on Premium Glass
Premium glass amplifies everything. Good technique looks stunning. Poor technique looks worse than on a standard window.
Sky-Frame's frameless design is designed to disappear, to let the view become the feature.
