Frosting & Privacy Film in New Zealand
Frosting and privacy film are some of the most effective ways to improve privacy, reduce glare, and add professional branding to offices, shopfronts, and internal glass partitions. This guide explains the different types of frosting available in New Zealand, how each option performs, what businesses typically spend, and how long these films last in real conditions. If you're planning a new office fit-out or want more privacy without replacing glass, this resource will help you make the right choice.
What Frosting & Privacy Film Is (and How It Works)
Frosting is a specialised vinyl film applied to glass to create privacy, reduce visibility, and give a clean, sandblasted look without replacing the glass itself. It diffuses light rather than blocking it, which means spaces stay bright while still gaining privacy. Unlike tinting, frosting works day and night and remains effective even when interior lights are on.
Frosting films are installed on interior or exterior glass and rely on a pressure-sensitive adhesive. Once applied, the vinyl bonds smoothly to the glass surface and provides long-term, low-maintenance privacy. Most frosting films are removable if needed, making them ideal for office refurbishments, leased spaces, or branding updates.
This section explains what frosting is made of and how the material behaves on glass.
Standard Frosted Vinyl (Opal / Etched Film)
This is the most common frosting used in offices and commercial fit-outs.
It has a uniform, soft “etched” appearance and provides strong daytime and nighttime privacy without darkening the room. Standard opal frosting is cost-effective, easy to maintain, and suitable for almost any glass partition, meeting room, or shopfront.
Perfect for: offices, clinics, retail, reception areas, and glass partitions.
High-Privacy Frosting (Full Coverage Films)
High-privacy films offer a denser, less translucent finish.
These films block silhouettes more effectively and are used when sensitive conversations or private workspaces are involved. They still allow light in but reduce visibility significantly more than standard opal frosting.
Common in: medical rooms, HR offices, legal and accounting firms, meeting rooms, and private client spaces.
Gradient and Decorative Frosting
Gradient frosting transitions from clear to opaque.
It’s popular in design-led offices where some visibility is desired without sacrificing a sense of openness. Decorative frosting can also include lines, bands, geometric shapes, or custom patterns that add visual interest while still offering partial privacy.
Ideal for: creative spaces, open-plan offices, coworking spaces, modern reception areas.
Printed Frosting (Logos, Patterns, Branding)
Printed frosting integrates branding elements directly into the privacy film.
This can include logos, repeated patterns, architectural overlays, or full custom graphics printed onto or cut from the frosting. It’s a premium option that elevates standard frosting into a branded feature without overwhelming the space.
Often used in: corporate offices, branded meeting rooms, hospitality fit-outs, and retail interiors.
Where Frosting Performs Best
Frosting is one of the most versatile privacy and design solutions for New Zealand businesses. It works in almost any environment where privacy, professionalism, or light control is needed. Because frosting diffuses light rather than blocking it, it keeps spaces bright while still reducing visibility. It is commonly used in office refurbishments, retail fit-outs, and commercial spaces where glass plays a major architectural role.
This section focuses on the practical environments where frosting delivers strong results.
Offices and Meeting Rooms
Frosting is the standard privacy solution for modern workplaces.
It provides confidentiality for staff and clients while maintaining an open, bright environment. It is used extensively on internal glass partitions, meeting rooms, HR offices, and front-of-house spaces.
Benefits include:
-
reduced distractions
-
protection for sensitive information
-
better visibility control
-
a clean, professional appearance
This is the most common application in Auckland commercial buildings.
Reception Areas and Client Spaces
Businesses often frost reception glass to create a welcoming, organised look for visitors.
It offers privacy for people checking in or waiting, without blocking natural light.
Common among: professional services, medical spaces, real estate offices, and modern retail environments.
Clinics, Healthcare, and Sensitive Workspaces
Healthcare and clinical environments rely heavily on high-privacy frosting.
These areas often require complete silhouette reduction for confidentiality.
Ideal for:
-
consultation rooms
-
treatment areas
-
internal windows
-
pharmacy counters
-
staff-only rooms
Frosting offers a clean, hygienic appearance without the maintenance requirements of blinds or curtains.
Retail Shopfronts and Fit-Outs
Retailers use frosting strategically to:
-
block back-of-house areas
-
conceal storage zones
-
create privacy for fitting rooms
-
add subtle branding
-
control visibility from foot traffic
For shopfronts where frosting sits alongside ACM panel fascias or exterior signage, you may also find our guide to ACM panel signage useful.
It’s also frequently used during renovations to maintain a tidy, professional appearance while work is underway.
Residential and Home Offices
Frosting is a modern alternative to curtains or blinds and is growing in popularity across New Zealand homes.
Typical applications include:
-
front door sidelights
-
bathrooms and showers
-
internal windows
-
home offices
-
street-facing glass
It provides privacy without darkening living spaces.
Glass Partitions and Internal Windows
Frosting is ideal for interior glass where privacy and openness both matter.
It is removable, can be updated easily, and works across small or large panels. Gradient and decorative versions are popular in open-plan layouts where partial visibility is preferred.
Safety Manifestation on Large Glass Panels
Frosting is also widely used for safety manifestation, helping prevent people from walking into clear glass.
Large doors and panels in workplaces, schools, retail spaces, and public buildings often require visibility markings to meet safety standards.
In New Zealand, manifestation commonly takes the form of:
-
horizontal frosting bands
-
dot patterns
-
repeated shapes
-
partial strips
These are typically placed at two heights for maximum visibility:
-
around 900–1000mm above floor level, and
-
around 1500–1600mm
Frosted bands are the most common option because they blend into modern interiors while still meeting safety requirements under the NZ Building Code.
Types of Frosting Available in New Zealand
There are several types of frosting used in New Zealand commercial and residential spaces. Each option provides privacy, but the performance, appearance, and cost vary depending on the film type and application. Below is a breakdown of the most common options and where each one performs best.
Opal Frosting (Standard Frosted Vinyl)
Opal frosting is the most widely used option in New Zealand.
It provides strong privacy with a clean, sandblasted look and works well on interior and exterior glass. It allows light to pass through but diffuses visibility, making it ideal for both small and large glass surfaces.
Best for:
-
offices
-
meeting rooms
-
reception areas
-
retail frontages
-
glass partitions
Opal is also the most cost-effective option, making it the standard choice for most commercial fit-outs.
Acid-Etched Look Films
Acid-etched films create a premium frosted appearance that is slightly softer and more diffused than standard opal.
They are often chosen for design-led interiors, high-end offices, and spaces where the aesthetic matters just as much as the privacy.
Key advantages:
-
subtle, high-end texture
-
slightly more light diffusion
-
good for architectural glazing
These films replicate the look of expensive etched glass at a fraction of the cost.
Patterned and Decorative Frosting
Patterned films include lines, bands, squares, shapes, or semi-transparent textures that add a visual design element to the glass.
These are often used to break up large glass panels, provide partial privacy, or add architectural detail.
Common uses:
-
coworking spaces
-
creative studios
-
open-plan offices
-
retail fit-outs
-
reception areas
Patterned films allow flexibility—privacy can be partial or full depending on the design.
Gradient Frosting
Gradient frosting transitions from clear at one end to fully frosted at the other.
This is popular in workplaces that want privacy without completely blocking visibility or light. It creates a softer separation between rooms and can be customised for width, opacity, and direction.
Best applications:
-
meeting rooms
-
reception glazing
-
internal partitions
-
areas that need light but less visibility
Gradients are increasingly popular in modern office designs.
Printed Frosting (Logos, Patterns, Branding)
Printed frosting integrates custom graphics directly into the film.
Designs can include logo patterns, geometric shapes, illustrations, or architectural overlays that blend with the office’s branding and interior design.
Advantages:
-
incorporates identity into privacy
-
highly customisable
-
premium finish
-
works across large glass areas
Printed frosting is often used alongside acrylic wall logos or reception features, so our Acrylic Signage Guide may also be helpful when planning interior branding.
This is commonly used by corporate offices and retail brands to elevate standard frosting into a design feature.
Full-Coverage Privacy Films
Full-coverage privacy films offer higher opacity than standard frosting.
They significantly reduce visibility and are used when confidentiality is essential. Although still translucent, these films block silhouettes more effectively than lighter frost options.
Best for:
-
HR offices
-
medical rooms
-
treatment areas
-
legal firms
-
private client spaces
-
back-of-house areas
They offer maximum privacy while still allowing natural light to pass through.
Frosting vs Alternative Privacy Solutions
Frosting is one of the most common privacy options in New Zealand workplaces, but it isn’t the only one. Businesses often compare frosting with blinds, curtains, tinted film, or even replacing glass entirely. This section breaks down how frosting performs against the main alternatives, helping you understand when it’s the most effective choice and when another option might be better.
Frosting vs Blinds
Blinds offer adjustable privacy, but they come with several drawbacks in commercial environments.
Frosting advantages:
-
no moving parts to maintain
-
looks cleaner and more modern
-
doesn’t block natural light
-
doesn’t collect dust
-
no cords or mechanisms
-
lasts significantly longer
Blinds tend to suit homes better than offices. Frosting is preferred for workplaces because it provides a permanent, low-maintenance solution that keeps the office bright and open.
Frosting vs Curtains
Curtains are rarely used in commercial settings because they:
-
require washing and maintenance
-
collect dust easily
-
darken rooms
-
take up space
-
wear out more quickly
Frosting provides the same privacy without adding fabric, weight, or visual clutter to the room. For modern office design, frosting is the more durable and hygienic option.
Frosting vs Tinted Film
Tinting reduces visibility from outside, but it isn’t a privacy solution, especially at night.
Once lights are on, tint behaves like clear glass — silhouettes remain fully visible.
Where tinting works:
-
glare reduction
-
heat control
-
UV filtering
Where frosting works:
-
true privacy day and night
-
silhouette reduction
-
design or branding integration
If privacy is the goal, frosting is almost always the better option.
Frosting vs Etched or Sandblasted Glass
Etched or sandblasted glass looks premium, but it is far more expensive and completely permanent.
Installing etched glass usually costs several times more than applying frosting and requires replacing the glass if the design ever needs to change.
Frosting advantages:
-
removable
-
easy to update
-
far more affordable
-
identical visual appearance
-
easy to repair or replace
This is why frosting is used in almost all NZ commercial refurbishments — you get the same clean architectural look without the high replacement cost.
Cost of Window Frosting in New Zealand
Frosting is one of the most cost-effective ways to add privacy, branding, or visual separation to glass.
Prices in New Zealand vary depending on the size of the panels, the type of film used, and how complex the installation is. The ranges below are realistic for Auckland commercial work and help set expectations before requesting a quote.
Businesses should treat these as general guidelines rather than fixed prices, as every project involves unique measurements, film types, and site conditions.
Typical Price Ranges
Below are approximate ranges based on the size and complexity of the job:
-
Small panels or doors → low hundreds
(e.g., small office windows, door bands, safety manifestation) -
Medium-sized offices or meeting rooms → mid hundreds
(full coverage on one glass wall; partial coverage on multiple panes) -
Printed or decorative frosting → higher hundreds to low thousands
(logo patterns, gradients, custom branding, multi-panel designs) -
Full office fit-outs → low to mid thousands
(multiple rooms, large partitions, reception areas, and branded elements)
These ranges include material, standard prep, and installation time.
What Affects the Final Cost
Several factors influence pricing, and understanding them helps businesses compare quotes accurately.
Glass Coverage Area
Larger panels or full-height walls increase both material use and install time.
Design Complexity
Straight-cut frosting is cost-effective.
Printed logos, patterns, bands, or decorative overlays increase labour time.
Type of Film
-
Standard opal frosting → most affordable
-
Acid-etched or premium films → higher cost
-
Printed or gradient options → premium tier
Height and Access
Glass at standard working height is quick to install.
High windows, reception glazing, and stairway panels may require ladders or additional labour.
Glass Preparation
Dirty or contaminated glass (especially in kitchens, gyms, or older buildings) takes longer to clean, adding to labour.
Edge Trimming and Detailing
Fine trims around frames or mullions require more precision.
After-Hours Installation
Many offices require after-hours work to avoid disruption.
This can add to the labour portion of a quote.
Installation Process & What to Expect
Most frosting installations are straightforward and can be completed with minimal disruption to your business. The process is clean, fast, and safe for both interior and exterior glass.
Understanding how installation works helps you prepare your space and know what to expect on the day.
On-Site Preparation
Before installation begins, the glass needs to be completely clean so the film can bond properly. This involves:
-
washing the glass surface
-
removing dust, fingerprints, and adhesives
-
checking edges and frames for contamination
-
taping out the layout if designs or bands are involved
For new offices or fit-outs, installers may also ask for access to the space before furniture is moved in.
Installation Timeframes
Frosting installs are relatively quick compared to other signage work.
Typical timeframes:
-
Small panels or doors → 30–60 minutes
-
Meeting rooms → 1–2 hours
-
Reception and office partitions → half-day
-
Full office fit-outs → half-day to a full day
-
Printed or decorative frosting → additional time for alignment and detail work
After-hours installations are available if the workspace needs to remain operational during the day.
How the Film Is Applied
Frosting is applied using a wet-application method:
-
a slip solution is sprayed onto the glass
-
the film is aligned
-
water and air are removed with a squeegee
-
edges are trimmed cleanly against frames or mullions
This method ensures an even finish with no dry spots, bubbles, or visible edges.
Curing and Bubble Settling
After installation, the film begins to “cure” as the water evaporates.
What to expect:
-
a slight haze for the first 24–48 hours (normal)
-
minor bubbles that disappear as the film dries
-
full clarity after a few days
In cold or humid environments, drying times can be slightly longer, but the end result remains the same.
Access and Workspace Requirements
Installers typically need:
-
clear access to the glass
-
a safe area to use ladders if required
-
enough space to unroll and trim film
-
good ventilation for slip-solution drying
If your workspace is busy, moving small items or clearing desks near the glass can help speed up the process.
Durability, Cleaning & Maintenance
Frosting is a long-lasting, low-maintenance solution for New Zealand offices and shopfronts. Once installed, it requires very little care and typically performs reliably for many years. This section explains how long frosting lasts, what affects durability, and how to keep the film looking clean and consistent over time.
How Long Frosting Lasts
Most high-quality frosting films last 5–10 years indoors.
In many cases, interior frosting can last even longer because it is protected from UV exposure, weather, and temperature changes.
Key durability notes:
-
interior installs last the longest
-
exterior-facing frosting may age sooner due to sunlight
-
premium films offer better clarity and longer lifespan
-
printed or patterned frost may need replacement sooner if heavily handled
For offices, clinics, and retail spaces, frosting is considered one of the most durable privacy solutions available.
Cleaning and Care Recommendations
Frosting is easy to clean and maintain.
However, certain cleaning products can damage the film over time, so it’s important to use the right approach.
Recommended cleaning:
-
microfibre cloth
-
mild detergent or glass-safe cleaner
-
warm water
-
soft, non-abrasive wiping
Avoid:
-
ammonia-based cleaners
-
harsh chemical sprays
-
razors or scrapers
-
abrasive pads or brushes
These can break down the film’s surface or cause clouding.
Heat, Humidity and Condensation
Frosting performs well in typical indoor environments, including kitchens, bathrooms, and moisture-prone areas.
Important notes:
-
condensation will not damage the film
-
heat from sunlight may shorten lifespan on exterior glass
-
interior frosting near showers or kitchens should be cleaned gently
-
high humidity does not affect adhesion when correctly installed
For exterior-facing windows, your film choice may influence longevity — premium films handle UV better than standard options.
When to Replace Frosting
Replacement is usually needed when:
-
the film becomes scratched or scuffed
-
branding changes
-
the office layout is updated
-
full coverage needs to be switched to partial (or vice versa)
-
decorative or printed elements need refreshing
-
exterior glass panels develop UV fade over many years
Because frosting is removable, updating or replacing panels is usually quick and cost-effective.
