Frequently Asked Questions About Dragonboard

General Product Questions

Composition, safety, and performance

What is Dragonboard made from and how is it different from traditional building boards?

Dragonboard is a magnesium oxide (MgO) board reinforced with fibreglass mesh. Unlike gypsum or cement-based boards, it is non-combustible, moisture-resistant, and incredibly durable—making it suitable for modern construction where performance and safety are paramount.

Is Dragonboard suitable for both internal and external applications?

Yes, Dragonboard is engineered for versatility. It can be used internally for walls, ceilings, and floors, as well as externally for sheathing, roofing, and cladding applications.

What thicknesses and sizes are available in the Dragonboard range?

Dragonboard comes in a range of thicknesses from 6mm to 20mm. Standard sheet sizes typically include 2400mm x 1200mm, with custom sizes available upon request.

Is Dragonboard resistant to mould, insects, and moisture?

Absolutely. Dragonboard’s composition makes it highly resistant to mould, mildew, rot, and insect infestation. It is an ideal solution for humid environments and areas prone to moisture.

How does Dragonboard perform in terms of fire resistance?

Dragonboard is classified as A1 non-combustible, offering outstanding fire resistance. It does not burn, emit smoke, or produce toxic fumes—making it an ideal choice for fire-rated assemblies and high-risk environments.

Installation & Handling

Working with Dragonboard on-site

Can Dragonboard be cut and installed using standard tools?

Yes, Dragonboard can be cut with common hand or power tools such as circular saws with a carbide-tipped blade. Always use dust extraction and appropriate PPE during cutting.

Is Dragonboard heavy or difficult to handle on-site?

While Dragonboard is denser than plasterboard, it remains manageable with standard site equipment. Thinner boards are easily handled by one person, while thicker boards may require a two-person lift or mechanical aid.

Do I need any special fixings or adhesives for installing Dragonboard?

No specialist fixings are required. Dragonboard can be secured with corrosion-resistant screws and bonded with high-performance construction adhesives where appropriate.

Roofing Applications

Flat and pitched roof suitability

Is Dragonboard suitable for flat roofs as well as pitched roofs?

Yes, Dragonboard performs well on both flat and pitched roofing systems. Its strength and moisture resistance make it particularly effective for exposed or weather-prone roofing structures.

What is the advantage of using 18mm tongue and groove Dragonboard for flat roofs?

The 18mm tongue and groove board offers enhanced structural stability and interlocking strength, ideal for flat roof applications. It reduces movement, resists moisture ingress, and supports load-bearing roof finishes like insulation and waterproof membranes.

Can Dragonboard be used beneath green roof systems or rooftop terraces?

Yes, Dragonboard is moisture-resistant and dimensionally stable, making it an excellent substrate beneath green roofs, rooftop terraces, or decking systems. It provides a solid, rot-proof base that won’t degrade over time.

Does Dragonboard offer good performance in extreme or unpredictable weather conditions?

Dragonboard is designed to perform in challenging environments. It resists warping, swelling, and deterioration caused by freeze-thaw cycles, heavy rain, and high humidity, ensuring long-term reliability.

SIPs (Structural Insulated Panels)

High-performance prefabricated panels

What are Dragonboard SIPs and how do they differ from standard SIPs?

Dragonboard SIPs are structural insulated panels that use Dragonboard as the facing material instead of OSB or plywood. This provides additional benefits such as fire resistance, water resistance, and improved durability—ideal for high-performance buildings.

What insulation values can I expect from Dragonboard SIPs?

Dragonboard SIPs are manufactured with high-performance insulation cores such as PIR or EPS, offering excellent U-values. Specific thermal performance depends on the panel thickness and insulation type but typically meets or exceeds UK Building Regulations.

Are Dragonboard SIPs suitable for residential and commercial builds alike?

Yes, Dragonboard SIPs are suitable for both residential and commercial construction. Their strength, fire rating, and insulating properties make them ideal for schools, hospitals, housing, and modular builds.
