Why should roof glass be laminated, not just toughened?
Overhead glass should be toughened laminated because it stays in place if it breaks. Toughened glass, also called tempered glass, is 5× stronger than raw glass, but when it breaks it falls as more than 50 small pieces per 50 × 50mm. Overhead, those pieces drop on people below. Laminated glass bonds two toughened panes with an interlayer that holds the broken glass in the frame.
So when you search for toughened glass for a roof, what you need is toughened laminated glass.
| Toughened | Toughened laminated | |
|---|---|---|
| When broken overhead | Falls as small pieces | Stays in the frame |
| Safety overhead | Not recommended | Recommended |
| UV | Lets most UV through | The interlayer cuts most UV |
| Sound | Standard | Better sound reduction |
| Price (₹/sq ft) | ₹75–200 | ₹360–585 |
Does a glass roof heat up, and what are the options?
A clear glass roof lets in sun and heat, so tinted or milky interlayers and reflective glass are used to cut glare. Tinted PVB softens the light, milky PVB diffuses it for privacy and less glare, and reflective glass bounces back more of the sun. All are available in toughened laminated glass on request. Ask us for the option that suits your roof and we will price it.

Glass roof and skylight FAQs
What is the price of glass for a roof per sq ft?
Glass for roofs should be toughened laminated. It costs ₹360–365 per sq ft in 13.52mm, ₹415–430 in 17.52mm and ₹560–585 in 22.28mm. These 2026 rates are for clear glass only, ex-works Sonepat, excluding GST and transport. Tinted or milky interlayers are priced on request.
Is toughened glass safe for a roof?
Plain toughened glass is not recommended overhead. If it breaks, it falls as small pieces on people below. Use toughened laminated glass for roofs, skylights and canopies, because the interlayer holds the broken glass in the frame. 13.52mm toughened laminated costs ₹360–365 per sq ft.
What is the best thickness for a skylight?
A small skylight usually uses 13.52mm toughened laminated glass. Pergolas, sit-out roofs and entrance canopies use 13.52–17.52mm. Large spans and walk-over glass are engineer-designed, with the thickness on request. Your structural engineer should confirm the glass for your roof, based on span, slope and loads.
Laminated or toughened glass for a roof?
Laminated, made from toughened panes. Toughened laminated glass stays in place if it breaks, cuts most UV and reduces more sound. Plain toughened glass is strong but falls as pieces when broken, so it is not used overhead. Toughened laminated roof glass starts at ₹360–365 per sq ft.
Does a glass roof heat up? Are tinted options available?
Clear glass roofs let in sun and heat. Tinted or milky PVB interlayers cut glare, and reflective glass reflects more sunlight. These options are available in toughened laminated glass on request. Tell us your roof size and the effect you want, and we will quote the glass.
Can you also do the fabrication for a glass roof?
Yes, on request. Our prices are for the glass only, cut to size, toughened and laminated. The frame, structure, sealing and installation are not included, and we can also take up the fabrication for your roof if you want. Send us your drawing and tell us what you need.
Is your roof glass BIS certified?
Yes. CLSG is certified to BIS IS 2553 Part 1 for architectural safety glass, which covers our toughened and laminated glass. We are also certified to Part 2 for road transport glass, and to IATF 16949. Our float glass comes from Saint-Gobain India and Emirates Float Glass.
Where do you deliver roof glass?
We deliver PAN India, dispatched from our plant in Sonepat, Haryana. There is no minimum order for toughened or flat laminated glass, so you can order glass for a single skylight. Send us your sizes and city, and we will quote the glass with transport.
What is the maximum size of a glass roof panel?
The maximum single toughened glass panel we make is 2400 × 3660mm. Toughened laminated glass is made from 9.52mm to 26.28mm. Larger roofs are split into several panels in a frame. Send us the roof size and frame drawing, and we will plan the panel sizes with you.
