Gyproc GlasRocX Board 12.5 x 1200 x 2400 T/E Edge, Glass-Reinforced for Exterior & Humid Areas

Dimensions & Weight: Glasroc X measures 1200mm (width), 2400mm (length), and has a thickness of 12.5mm. The board weighs approximately 11kg, making it easier to handle and install compared to heavier alternatives like cement particle boards.

Fire Resistance: Glasroc X has a reaction to fire rating of Euroclass A1 (BS EN 13501-1), meaning it is non-combustible. It can provide fire resistance for up to 120 minutes under certain conditions, making it suitable for applications requiring enhanced fire safety.

Moisture & Mould Resistance: Glasroc X features mould-resistant properties due to its glass fibre mat reinforcement and hydrophobic coating, making it particularly effective in humid environments and areas prone to moisture exposure.

Installation: Installation involves scoring the board with a sharp knife and snapping it over a straight edge. For optimal weather protection and UV performance, it is recommended to fix the boards with the printed side facing outward.

Thermal Properties: Glasroc X has a thermal conductivity of 0.186 W/mK and provides a thermal resistance of 0.067 m²K/W for the 12.5mm board, helping maintain energy efficiency in buildings.

Extreme Temperature Use: Glasroc X is suitable for use in freezing conditions but is not recommended for environments where temperatures exceed 49°C.

Environmental Benefits: Glasroc X is made from 100% natural gypsum and is recyclable, making it an environmentally friendly option for construction projects.

Gyproc GlasRocX is a gypsum-based plasterboard designed for walls and ceilings in domestic and commercial buildings. It combines high fire resistance, moisture resistance, and strong performance for improved durability and acoustic insulation.

GlasRocX is available in thickness options of 12.5 mm and 15 mm. Common sheet sizes include 1200 × 2400 mm and 1200 × 3000 mm, with weight varying by thickness. The product page lists the variants, so choose the size that fits your installation.

GlasRocX generally offers higher fire resistance and improved acoustic performance, while Gyproc Moisture Resistant boards are optimized for damp environments. If fire safety and sound insulation are priorities, GlasRocX is typically the stronger choice.

Gyproc Firestop boards are specifically designed for fire-rated assemblies with dedicated fire certifications. GlasRocX also provides strong fire resistance and moisture resistance along with enhanced acoustic insulation, so choose based on the exact fire rating requirements and environmental conditions.

GlasRocX is moisture resistant, making it suitable for many damp environments. For areas with direct water exposure or heavy moisture, follow manufacturer guidance and consider additional protective measures.

Typical installation involves fixing boards to studs with drywall screws (about 300 mm spacing at edges and 600 mm in the field), cutting with a utility knife, and then sealing joints with tape and joint compound before finishing.

Wear eye protection, gloves, and a dust mask. Work in a well-ventilated area, use a sharp utility knife or saw for clean cuts, and clean up dust to minimize exposure.
