A splashback is a wall finish that still has to behave like glass

A kitchen splashback is the most photographed pane in many renovations and the easiest one to specify badly. The sample on the bench is a colour. The installed pane is a piece of glass that must stay attached to a wall, tolerate heat and cleaning, and sit inside Housing Provisions Part 8.4 if it is in a kitchen and the lowest sight line is less than 2.0 m above the finished floor.

This hub is for homeowners and trades who need the questions in the right order. It is not a colour chart and it is not a glazing quote.

What the pane is doing

A splashback keeps grease and water off the lining. In glass, that usually means a painted or coated face on the wall side and a glossy face toward the room. Ordinary float has a slight green edge. Low-iron glass reduces that tint so a white or pale colour reads closer to the sample. Neither fact tells you whether the pane is toughened, laminated, or annealed.

Most installed splashbacks in contemporary kitchens are heat-treated because fabricators prefer a pane that can take holes, cut-outs and thermal stress. That is a workshop practice, not a sentence we will dress up as a statistic. What the NCC actually writes is the annealed-with-adhesion path in 8.4.6, and a pointer to AS/NZS 5601 near gas appliances.

The 8.4.6 splash-back path, in the Code’s words

Part 8.4 applies to kitchens, bathrooms, ensuites, spa rooms and the like. For splash-backs, monolithic annealed glass may be used provided it is fully backed by and continuously adhered to a solid wall material or a fixed cabinet or bench that is:

1. a height not less than 760 mm; and
2. a depth not less than 300 mm; and
3. extending the full width of the splash-back; and
4. located in front of the splash-back.

That is a construction test, not a style test. A pane that stops in a shadow line above an open void, or that is only spotted with adhesive, is not this path. If the job is not using the annealed exception, treat the pane as kitchen glazing under the rest of 8.4.6: framed panels as Grade A safety glazing to Table 8.4.2, or exposed-edge panels as toughened safety glass to Table 8.4.6 with a minimum nominal thickness of 6 mm.

Ask the installer which of those sentences they are using. Ask to see the mark required by 8.4.8 if the pane is safety glass.

Heat, cooktops and the standard we will not fake

Glass next to a cooktop sees a different temperature than glass behind a fridge. We will not invent a clearance chart. The ABCB’s own explanatory note under 8.4.6 sends glass splashbacks used near gas appliances to AS/NZS 5601. That is the honest citation. An induction cooktop is not a reason to ignore backing and adhesion; it is a reason to ask the practitioner whether 5601 still applies to the appliance you actually bought.

Cut-outs for power points need polished or arrised edges and enough land around the opening. Holes too close to an edge are a fabrication limit, not an NCC table. Put them on the shop drawing before the pane is tempered. Toughened glass cannot be recut.

Colour, paint and the wall

Painted glass is only as good as the paint system and the substrate. A dark colour on ordinary float will still show a green edge. A pale colour on ordinary float will shift. Low-iron glass reduces that shift; it does not make a cheap paint system archival. Ask what is between the paint and the plasterboard: full-bed adhesive, a backing board, or a cavity. 8.4.6’s annealed path wants continuous adhesion to a solid wall material or to that qualifying bench.

If the splashback turns a corner or climbs a window reveal, you are no longer in a single rectangle. Joints, silicone colour and whether a return is a separate pane all change cleaning and movement. None of that is a reason to skip the human-impact clause.

How this hub connects

The long explainer is kitchen splashback glass choices. Low-iron / Starphire covers the substrate without treating a trademark as our product. Costs lists the factors — size, paint, low-iron, cut-outs, removal of tiles — without a price. Safety standards keeps the NCC and AS 1288 in one place.

Bring a photo of the wall, the cooktop model, and a question about adhesion. Leave the sample book for after those three things are settled.

Field note on splashbacks (1)

Adhesion and the gas pointer come before the colour chip.

Keep Housing Provisions 8.4 open if people can hit the glass. Keep Part 11.3 open if people can fall. Keep B1D4 open if you are arguing about AS 2047 versus AS 1288. Then write the clause on the request for quote and let a licensed practitioner correct you.

This site will not invent a price, a ranking, an operator or a statistic to decorate that loop. If you need a guest-post citation, cite the ABCB or Standards Australia page, not a memory of this paragraph. If you need a pane on Friday, you need a glazier, not another sentence from an editorial desk.
