In construction projects today, builders and contractors are looking for innovative building materials that can improve efficiency, sustainability, and performance. One such material that is gaining popularity is glass mat sheathing board from manufacturers like Mada Gypsum, Saudi Arabia. With its unique properties and construction benefits, glass mat sheathing is emerging as a preferred choice for sheathing in both residential and commercial buildings.

What is Glass Mat Sheathing Board?

Glass mat sheathing board is a high-performance exterior sheathing material made by embedding a fiberglass mat between two layers of gypsum. The glass mat gives the board enhanced strength and moisture resistance compared to traditional gypsum boards. These boards come in various sizes and thicknesses  to suit different application needs.

Benefits of Glass Mat Sheathing Board

Using glass mat sheathing boards offer several advantages over traditional sheathing options:

Improved thermal performance – The fiberglass mat gives higher R-value, improving insulation and energy-efficiency.
Enhanced moisture resistance – The embedded glass mat provides superior water resistance, making it ideal for wet areas.
Better fire resistance – These boards have fire ratings of up to 2 hours.
Lighter weight – These boards are lighter than exterior gypsum or plywood sheathing.
Superior strength – The boards have high tensile strength to resist wind loads and impacts.
Faster installation – The boards are easy to cut, handle and install.

Properties of Glass Mat Sheathing Board

The core properties that make these boards a preferred choice are

Durability – Glass mat boards are durable with high impact resistance.
Mold resistance – The glass mat core makes it mold and mildew resistant.
Dimensional stability – The boards are dimensionally stable and do not warp or delaminate.
Moisture resistance – Glass mat sheathing has low water absorption, making it ideal for wet areas.
Fire resistance – Glass mat boards have fire ratings from 1 hour to 2 hours.

Applications of Glass Mat Sheathing Board

These boards have become a versatile material suitable for:

Backer board for cladding systems – Used behind metal, EIFS, brick, and other claddings.
Tile backing board for wet areas – Provides water protection behind tile walls.
Sheathing material for exterior walls and roofs – Improves weather resistance and insulation.
Shaft wall assemblies – Suitable for fire-rated stairwells and elevator shafts.

How to Install Glass Mat Sheathing Board?

Installing a Glass Mat Sheathing Board is as simple as installing a plasterboard. Please follow the manufacturer’s installation guidelines and the architects’ requirements.


With its unmatched strengths, mold resistance, and thermal performance, glass mat sheathing boards are becoming the top choice for builders today.
