Glass Frosting and Window Graphics: Options and Costs

Short answer: Window graphics are adhesive films applied to glass. Frosted vinyl gives privacy and an etched-glass look; one-way vision film shows a graphic outside while you can see out; printed decals add branding or promotions. In Singapore, unframed full-height glass doors must carry two contrasting bands at least 100 mm high under BCA's Accessibility Code, which frosting can provide neatly.

The main window graphic options

Option	What it does	Typical use
Frosted (etched-look) vinyl	Translucent film that blurs the view but lets light through	Meeting rooms, clinics, toilets, privacy bands
Cut frosted vinyl	Frosting with a logo, pattern or text cut out	Office glass walls, branded doors
Printed frosted vinyl	Frosting with printed colour or patterns	Feature partitions, brand walls
Gradient frosting	Frosting that fades from solid to clear	Privacy at seated height, light above
One-way vision film	Perforated film: graphic outside, see-through inside	Shop windows, vehicle rear windows
Printed window decals	Full-colour print on clear or white vinyl	Promotions, opening hours, menus
Cut vinyl lettering	Individual letters cut from coloured vinyl	Shop names, opening hours, door numbers

Solar and tint films are a different product: they reduce heat and glare rather than carry graphics.

Privacy: how much frosting do you need?

For meeting rooms and clinic consultation rooms, a frosted band covering roughly seated to standing eye level usually gives enough privacy while keeping light and openness. Full-height frosting gives complete privacy but can make a space feel closed. Gradient and patterned frosting are good compromises.

The glass door marking rule

Singapore's Code on Accessibility in the Built Environment 2019 (clause 4.4.5) requires unframed full-height glass doors to be marked so they are visible:

• Two horizontal bands, each at least 100 mm high, in a contrasting colour.

• The upper band between 1,400 mm and 1,600 mm above the floor.

• The lower band between 850 mm and 1,000 mm above the floor.

• Where a band is made of several pieces (such as a logo pattern), their total width in each zone must be 100 mm or more.

Frosted or coloured vinyl bands, or a cut logo pattern within those heights, meet this neatly. Our accessible signage guide covers the rest of the code.

One-way vision film: how it works

One-way vision film is perforated with small holes. From outside, your eye sees the printed graphic; from inside, it looks through the holes. It works when it is brighter outside than in, so during the day. At night with lights on inside, the effect reverses and people outside can see in. Rain or condensation in the holes also reduces visibility, so on vehicles a laminated version is often used.

Installation and lifespan

Window film is usually applied to the inside of the glass, where it is protected from weather and cleaning. It is applied wet or dry depending on the film, smoothed to remove bubbles, and trimmed to the frame. Clean glass is essential: dust or old adhesive shows through.

Indoor frosted vinyl typically lasts many years. Printed graphics facing the street fade faster in direct sun, so for long-term branding choose UV-resistant inks with a laminate, or cut vinyl. Good-quality film removes cleanly when you move out; cheap film can leave adhesive behind.

What window graphics cost

Window graphics are usually priced per square metre plus installation, and depend on the film, printing, cutting complexity and access.

Item	Typical price (SGD)
Plain frosted vinyl, supplied and installed	[A&S to add: per m²]
Cut frosted logo or pattern	[A&S to add: per m² or per job]
One-way vision print	[A&S to add: per m²]
Printed window decal	[A&S to add: per m²]

Window graphics for shops

• Keep promotional decals to part of the window so people can still see in; a fully covered window can look closed.

• Put opening hours, phone number and payment methods near the door at eye level.

• Use cut vinyl for the shop name on the glass when a full signboard isn't allowed or as a second sign at eye level.

• Large street-facing graphics may count as an outdoor sign; check with your sign maker before covering a frontage.

Caring for window film

Clean with mild soapy water and a soft cloth or squeegee. Avoid abrasive pads, ammonia-based cleaners and scraping the film edges.

Frosting patterns and ideas

• Plain band: a clean strip at eye level, the simplest privacy solution.

• Gradient: frosting that fades to clear, keeping light and openness above.

• Stripes or lines: horizontal lines give partial privacy with a modern look.

• Logo repeat: your logo cut from the frosting as a pattern, branding every pane.

• Clear logo on full frosting: full privacy with the brand mark left clear.

• Printed colour: frosted film printed with brand colours or imagery for feature walls.

Worked example: a meeting room glass wall

An office has a 4 m glass wall and an unframed full-height glass door into its meeting room. The design:

1. A frosted privacy band across the wall at seated eye level, so people outside can't see screens and faces.

2. Contrasting bands on the door within both heights the Accessibility Code requires (850 to 1,000 mm and 1,400 to 1,600 mm, each at least 100 mm high), using the company's logo pattern.

3. The room name cut into the frosting beside the door.

The result meets the glass door marking rule, gives privacy and carries the brand, from one film installed in a day.

Frequently asked questions

What is the difference between frosted vinyl and tinted film?

Frosted vinyl blurs the view for privacy and decoration. Tinted or solar film reduces heat and glare while staying mostly see-through.

Do glass doors need markings in Singapore?

Yes. Unframed full-height glass doors need two contrasting bands at least 100 mm high: one between 1,400 and 1,600 mm and one between 850 and 1,000 mm above the floor.

Can people see through one-way vision film at night?

When it is brighter inside than outside, yes. One-way vision works best in daylight.

Is window frosting removable?

Yes. Good-quality film peels off cleanly, which suits rented offices and shops.

Is frosting applied inside or outside the glass?

Usually inside, where it is protected from weather and wear.

How long does frosted film last?

Indoors, good-quality frosted film typically lasts many years. Film facing strong sun or applied outside wears faster.

Can frosting go on curved glass?

Often, using a flexible film, depending on how tight the curve is. Ask your installer to check on site.
