Overview
Wedge MgO board (WEMAG-S 1000) is a magnesium oxide board supplied in thirteen thicknesses from 4 mm to 25 mm, at a standard 2440 × 1220 mm sheet size. Every thickness is the same board to the same specification — the choice is driven by the application. Tell us the thickness and quantity and we quote within 24 hours.
MgO board is specified where gypsum fails: humid and wet interiors, external soffits, coastal projects and fire-rated construction. It is dimensionally stable in moisture, it is non-combustible, and it takes a screw fixing without the crumbling you get from saturated plasterboard. It is also the standard sheathing board in LGSF, modular and prefab buildings.

MgO board and NBCS 2026
India’s move from NBC 2016 to NBCS 2026 replaced prescriptive material lists with a performance route. For a fire-rated partition the tested system report decides compliance, not the board name on the drawing. MgO board is well placed under this regime because one board can carry combined fire, acoustic and thermal performance — but only if you can produce a current test certificate. We issue ours with every quotation.

Frequently asked questions
What is the price of MgO board in India?
Indicative project rates per 2440 × 1220 mm sheet are INR 650–850 (USD 6.8–8.9) for 6 mm, INR 900–1,200 (USD 9.4–12.5) for 9 mm and INR 1,200–1,600 (USD 12.5–16.7) for 12 mm, ex-works and excluding 18% GST. Other thicknesses are quoted on request.
What thickness of MgO board do I need?
4–6 mm for ceiling and lining work; 8–12 mm for wall linings and partitions; 15–20 mm for structural sheathing and flooring; 25 mm where a single-layer fire or impact rating is required. Tell us the application and we will specify it.
What is the MgO board size?
All thicknesses are supplied at 2440 × 1220 mm as standard. Cut-to-size is available on bulk orders.
Is MgO board suitable for wet areas?
Yes. Magnesium oxide board is dimensionally stable in humid and wet conditions, which is the main reason it is specified over gypsum in bathrooms, kitchens, external soffits and coastal projects.
Can MgO board be used for fire-rated construction?
Yes. MgO board is non-combustible and commonly specified in fire-rated partitions and linings. Under NBCS 2026 the compliance route is performance-based, so the tested system report decides. Request the current test certificate with your quotation.
Do you export MgO board?
Yes. Wedge Industries Limited manufactures in India, the UK, Spain and China and exports to 45+ countries, with regular shipments across the Gulf and South East Asia.
