Product Overview
Siniat GTEC dB Board 12.5 mm (Tapered Edge) (2400 mm × 1200 mm) is a high‑performance, dense gypsum board engineered specifically for use in areas where enhanced acoustic and fire‑rated performance is required. With its 12.5 mm thickness and large sheet size, it is ideal for internal wall partitions, ceiling linings and separating systems in residential and multi‑occupancy buildings.
Key Features & Benefits
- Superior acoustic performance — capable of reducing noise by up to ~45 dB Rw in appropriate systems
- Fire‑resistant performance — reaction to fire Euroclass A2‑s1,d0
- Dense and heavy board core for improved performance compared with standard plasterboard
- Tapered Edge (TE) finish for smooth jointing and streamlined finishing
- Colour‑coded: blue front face, grey back face for easy identification on site
- Thermal conductivity λ = 0.25 W/mK (to BS EN 12524)
- Compatible with the full range of Siniat jointing, finishing and board systems for simplified installation
Applications / Typical Uses
- Ideal for separating walls, partitions and linings in residential, multi‑occupancy accommodation, hotels and commercial buildings where acoustic performance is critical
- Suitable for use in both new build and refurbishment contexts requiring improved sound insulation and fire performance
- Often used in stud partition systems, office fit‑outs, corridor and shaft linings, hotel rooms and other spaces with acoustic control requirements
Installation & Handling
- Store boards flat on a dry, level surface, protected from moisture and damage prior to installation
- Handle with care to avoid damage to edges and faces
- Cut using the “score and snap” method — no power tools needed
- Fix with suitable screws (self‑tapping for thin gauge metal, self‑drilling for thicker gauge metal, high‑thread for timber) in accordance with Siniat recommendations
- Use Siniat approved jointing and finishing systems; prime joints and board faces with Siniat Jointing Systems and Sealer prior to decoration
