Product Overview

Siniat GTEC Moisture Board 15 mm Tapered Edge (2400 mm × 1200 mm) is a premium gypsum board specially engineered for high‑humidity internal environments. With a 15 mm thickness and large sheet format, it provides dependable performance in kitchens, bathrooms, utility rooms and other humid internal spaces.

Key Features & Benefits

  • Moisture‑resistant core and liner, designed to perform in humid areas (complies with Type H2 under BS EN 520)
  • Reaction to fire classification: Euroclass A2‑s1,d0 — limited combustibility and low smoke emission
  • Thermally conductive: λ = 0.25 W/mK (to BS EN 12524:2000) and thermal resistance R ≈ 0.060 m²K/W for 15 mm thickness
  • Lightweight yet robust: mass ~11.9 kg/m² for 15 mm board; individual board weight ~34.3 kg for 2400 × 1200 × 15mm
  • Colour‑coded green on both faces for easy identification of moisture‑resistant board type
  • Tapered edge (TE) format for ease of jointing and finishing
  • Smooth surface ready for decoration or skim finish, offering efficient installation
  • Ideal size (2400 × 1200 mm) gives fewer joints and good coverage

 

Applications / Typical Uses

  • Suitable for internal wall linings and ceilings in humid areas such as kitchens, bathrooms, utility rooms and laundries
  • Ideal for both new build and refurbishment projects where moisture resistance is required
  • Suitable as a reliable liner in residential, commercial or institutional buildings exposed to increased humidity

 

Installation & Handling

  • Store flat on a dry, level surface and protect from direct exposure to moisture prior to installation
  • Handle with care to avoid damage to edges and board faces
  • Cutting can be done using the “score & snap” method—no power tools required
  • Fix using appropriate screws or fixings depending on substrate, in accordance with Siniat system guidance
  • After installation, joint and finish using Siniat approved jointing systems. Prime with Universal Sealer before decoration

 

Compliance & Certification

  • Manufactured in accordance with BS EN 520:2004 + A1:2009 Type H2 (moisture resistant gypsum boards)
