Frosted vs clear glass: which one to choose?

The main difference: privacy or light

When choosing glass for an interior, two questions matter most: how much light should pass through, and how much should be visible from the other side. Clear glass transmits ~90% of light and 100% of the image. Frosted glass transmits the same amount of light, but the image becomes a blurred silhouette. Acoustic and thermal insulation do NOT depend on the finish — they are determined by glass thickness and the layers used.

Clear glass

The standard for partitions, doors and storefronts where a visual connection is important. Clear glass is suitable when:

• you want to keep light flowing across the entire plane;
• a visual link is needed between two spaces (kitchen-living room, office corridor-private offices);
• a small room needs a sense of openness;
• for storefronts, exhibition halls and shopping centres.

Drawback: fingerprints and smudges show. Solution: nano-coating or anti-fingerprint protective coating.

Frosted glass production methods

1. Sandblasted glass

The glass surface is mechanically roughened with a sand jet. Result: opaque finish, light transmission ~80%. Can be partial (patterns, transparent stripes). Drawback: the surface absorbs dirt, so a protective coating is needed.

2. Satin-etched (acid etching)

Glass is chemically treated with hydrofluoric acid. The surface is smooth and silky (not granular like sandblasted). Light transmission ~85%, easier to clean, fingerprints less visible. A premium option — about 30% more expensive than sandblasted.

3. Frosted film

An adhesive frosted film applied to clear glass. The cheapest option (~€15 per m²), no need to replace the glass. Available with patterns or logos. Drawback: lasts 5-7 years, and edges can start peeling.

4. Ceramic printing

A pattern is printed with ceramic ink, then the glass is tempered. The pattern becomes permanent, resistant to chemicals and daily cleaning. Suitable when a custom design element is needed (logo, motif) — from €50/m². Lasts as long as the glass.

Application guidelines

• Bathroom partition / shower zone: frosted (privacy, soft light)
• Meeting rooms (in open offices): frosted, or clear with a frosted band at about 1 m height (so seated people aren't visible)
• Kitchen-living room partition: clear (to connect spaces)
• Bedroom: frosted (privacy)
• Storefronts: clear (visibility)
• Entrance doors: frosted or decorated (security + aesthetics)

Price comparison

Typical prices for an 8 mm tempered glass door (1 m × 2.2 m):

• Clear: base price (~€250)
• Frosted film: +€30 (separate lamination work)
• Sandblasted: +€50-75 (~25% more expensive)
• Satin-etched: +€75-100 (~30% more expensive)
• Printed pattern: +€120-250 (depending on complexity)

FAQ

Can frosted glass be converted back to clear?

Film — yes (it can be removed). Sandblasted or satin-etched — no, because the glass surface has been chemically or mechanically altered. The whole panel will need replacing.

Does frosted glass get dirty faster?

Sandblasted — yes, because its grainy surface holds soap residue and grease. Satin-etched — no, the smooth surface cleans easily. Film performs similarly to clear glass.

Can clear and frosted be combined in the same project?

Yes, and it's a common design solution. For example: a partition with a frosted lower section (1-1.2 m high, so seated people aren't visible) and a clear upper section. Or doors with a clear top and frosted bottom.
