Glass Structural Safety,
Calculated to Standard
GlazSafe is a browser-based glass thickness and safety calculator for façade consultants, glazing contractors, and architects — producing IS 16231-compliant workings with a PDF report you can submit.
Glass thickness is still calculated in Excel. Most glazing professionals in India rely on shared spreadsheets with no traceability, no standard references, and no report they can submit. One wrong cell and the wrong panel goes up. GlazSafe fixes this.
From site parameters to safe thickness in minutes
No installation. No spreadsheet. Open the browser, enter your project parameters, get the answer.
Enter project parameters
Panel dimensions, building location, terrain category, height, and occupancy type. Dropdowns guided by IS 875 wind zone data for Indian cities.
Wind load calculated
Design wind pressure computed using IS 875 Part 3 — risk coefficient, terrain factor, topography factor, and cyclone importance factor applied correctly.
Thickness determined
Linear interpolation on the 6,600-row IS 16231 Part 3 reference dataset. Stress checks and Annex C deflection checks performed automatically.
Download PDF report
Step-by-step engineering workings, standard references, SAFE / UNSAFE verdict, and governing criterion — ready to attach to a project submission.
Built for professionals who need to get it right
Every feature designed around how glazing professionals actually work in India.
IS 16231 interpolated area lookup
Linear interpolation on the full 6,600+ row IS 16231 Part 3 reference dataset — bracketing design wind pressure between tabulated rows for precision.
IS 16231 Part 3 : 2019IS 875 wind load engine
Complete design wind pressure calculation — basic wind speed by city, terrain category, risk coefficient k₁, height factor k₂, topography k₃, cyclone k₄.
IS 875 Part 3 : 2015Submission-ready PDF report
Every calculation step shown with its standard reference. Governing criterion called out. A report your client or reviewer can follow without calling you.
With standard referencesVisual stress indicator
Physics-driven panel animation shows deflection under wind pressure — instantly communicates whether the selected glass is safe or unsafe for the loading condition.
Deflection visualisationAnnex C deflection checks
Verifies centre-of-glass deflection under peak design pressure against the L/60 guideline. Aspect ratio limits checked automatically against the standard.
Structural safetyMulti-standard architecture
Built to expand. ASTM E1300, AS 1288, BS 6262 and CS 92 support coming in subsequent phases — same interface, same report format, different standard engine.
Expanding to APAC & EuropeEvery step shown,
every reference cited
GlazSafe doesn't just give you an answer. It shows you how it got there — the same way a structural engineer would present their working.
Indian standards today, international expansion coming
GlazSafe is built on a multi-standard engine. New standards require only a new engine file — the rest of the platform stays unchanged.

Whether you design it, fabricate it, install it, or sell it — if glass thickness is your responsibility, GlazSafe is for you.
Façade Consultants
Run IS 16231 calculations in minutes instead of hours. Produce client-ready PDF reports with full engineering workings. Stop maintaining spreadsheets.
Glazing Contractors
Verify panel specifications before quoting. Avoid the risk of under-specifying and the cost of over-specifying. Get a calculation you can show the client.
Architects
Run a quick sanity check on glass specifications for commercial and institutional projects before calling a structural engineer. Fast, credible, standards-based.
Glass Manufacturers
Equip your sales team with a professional tool. Help customers specify the right product — and make recommendations you can stand behind.
A report you can attach to a submission
Every GlazSafe calculation generates a PDF with step-by-step workings, standard clause references, and a clear SAFE / UNSAFE verdict. The kind of document your client, reviewer, or certifier expects.
