What is fluted glass?

Fluted glass is a type of textured glass with uniform vertical ribs running across the surface, also known as reeded glass or ribbed glass. The ribbed texture diffuses light while providing partial privacy: shapes and silhouettes are visible through the glass, but fine details are obscured. Fluted glass is a decorative glass used in partitions, doors, windows, kitchen cabinets, shower enclosures, and building facades.

What is the fluted glass price per sq ft?

The fluted glass price per sq ft depends on thickness, base glass type (clear or tinted), tempering requirement, edge finishing, and order quantity. Tempered fluted glass carries a processing premium over annealed fluted glass. Tinted and Low-E variants carry additional premiums.

Can fluted glass be tempered (toughened)?

Yes. Karnataka Metal Company tempers fluted glass at its Nelamangala plant in Bangalore. Tempered fluted glass is 4 to 5 times stronger than annealed glass and breaks into small, blunt granules if shattered. Tempering is BIS/ISI certified per IS 2553. Fluted toughened glass is required for doors, shower enclosures, partitions in public areas, and any application where safety glass is mandated by NBC 2016.

Is fluted glass the same as figured glass?

Fluted glass is one type of figured (patterned) glass. The term “figured glass” covers all textured patterns including pinhead, cross-reed, and other designs. Fluted glass specifically refers to the linear vertical ribbed pattern, also called reeded glass. Karnataka Metal Company supplies both fluted glass and other figured glass patterns.

What is the difference between fluted glass and frosted glass?

Fluted glass has a raised ribbed texture that creates a linear visual pattern and diffuses light directionally. Frosted glass has a uniform matte surface (sandblasted or acid-etched) that diffuses light evenly with no visible pattern. Fluted glass provides partial privacy (silhouettes visible), while frosted glass provides near-complete privacy. Fluted glass is chosen for its decorative effect; frosted glass for maximum obscurity.

What fluted glass design options are available?

The standard fluted glass design features uniform vertical ribs running the full height of the panel. Karnataka Metal Company can supply fluted glass in clear and tinted (grey, bronze) base glass. Tempered configurations are available for different performance requirements. Contact the sales team to discuss specific fluted glass design requirements for your project.

Can fluted glass be used for exterior windows and facades?

Fluted glass can be used for exterior windows and facades, but in practice this is almost never done. For exterior use the glass must be tempered, since fluted glass cannot be laminated. A fluted DGU configuration is technically possible but never done in practice. Most fluted glass applications are interior, such as partitions, doors, and feature walls.
