Clear vs Starphire Glass – What’s the Real Cost Difference?
Starphire is a brand name for low-iron glass – glass made from raw materials with reduced iron content. Standard clear float glass has a faint green tint that’s most visible at the edges, in thick panels, and where two pieces overlap. Starphire is much closer to truly colourless and has bright, almost-white polished edges. The upcharge runs about 30-60% over equivalent clear glass. For some projects it’s transformative; for others, you genuinely can’t tell the difference at arm’s length. Below is how to decide whether it’s worth the spend.
What does the green tint look like in normal glass?
Hold a piece of standard 3/8″ clear tempered up edge-on against a white background. You’ll see a clear green stripe – that’s iron content in the glass. In a finished shower or railing the green shows mostly at the polished edges, in stacked or layered panels, and on photos shot near windows where the light passes through twice.
Where does Starphire make the biggest visible difference?
Three places: at the edge (Starphire edges look bright white instead of green), with thick glass (1/2″ or thicker, where green compounds), and in shower enclosures with white tile or white walls (the green tint visually fights the whites). Less noticeable where the back wall is dark or coloured.
What’s the cost upcharge?
For a typical frameless shower in 3/8″: Starphire adds about $400-$800 to a basic enclosure, more for larger projects. For a glass railing run: about 40% more than standard clear glass for the same thickness and specification. The premium reflects the higher-purity raw materials and tighter manufacturing tolerances required to remove the slight green tint visible in standard glass.
Is Starphire stronger than clear glass?
No. Strength comes from the tempering process, not the iron content. A tempered Starphire panel and a tempered clear panel of the same thickness are mechanically identical. Both can be laminated, both meet safety standards.
Does Starphire clean differently?
No. Same cleaners, same care. The surface is identical chemistry; only the bulk colour is different.
Where does Starphire NOT make sense?
Storefront glass – at distance you won’t see edge tint, and Starphire is more expensive in the larger thicknesses commercial work uses. Interior glass that’s mostly viewed face-on with no thick edge exposure. Coloured-backsplash showers where the back wall is dark or saturated and the green tint is invisible against it.
What about other low-iron brands?
Starphire is one brand (Vitro/PPG). Other low-iron names: Optiwhite (Pilkington), Diamant (Saint-Gobain), Krystal Klear, Ultra-Clear. All are similar in performance and price band. We source based on availability and quality at the local tempering plants – the product spec matters more than the brand name.
Can I see a sample before deciding?
Yes – we bring polished sample tiles of clear and Starphire on the consult so you can compare them side-by-side under your own lighting. That’s the only way to make a real decision. The difference looks much bigger in person than in catalogue photos.
