Paint-Free Gypsum Board
Paint-Free Gypsum Board (also known as pre-finished gypsum board, self-finished gypsum board, or laminated gypsum board) is an advanced interior building panel that eliminates the need for on-site painting or plastering. It features a factory-applied decorative surface layer bonded to a standard gypsum core, offering a ready-to-install, finished wall/ceiling solution.
| Feature | Details |
|---|---|
| Decorative & Eco-Friendly | New decorative material made from building gypsum with a pre-applied decorative layer (wood grain, solid color, etc.). No on-site painting required, reducing release of harmful substances like formaldehyde. |
| Thermal Insulation | Core contains ~60% micro-pores. Low thermal conductivity of air delivers excellent lightweight thermal insulation performance. |
| Fire Resistance | Gypsum core is non-flammable and absorbs large amounts of heat via endothermic chemical reactions when exposed to fire, delaying temperature rise and providing good flame retardancy. |
| Sound Insulation | Unique cavity structure delivers superior sound insulation, outperforming single-layer lightweight materials (e.g., aerated concrete, expanded perlite board) that require excessive thickness for equivalent performance. |
| Decorative Function | Smooth surface; seamless joints after treatment allow direct decoration. |
| Processability & Constructability | Can be nailed, planed, sawed, glued, and cut on-site with a paper cutter for fast, convenient installation. Greatly improves construction efficiency. |
| Humidity Regulation ("Breathing" Function) | High porosity and optimized pore structure enable high ventilation performance: absorbs moisture when indoor humidity is high, releases moisture when air is dry, regulating humidity for a comfortable living environment. |
| Space Saving |
Ultra-thin wall material (minimum 7mm thickness) that maintains sound insulation and fire resistance, reducing wall thickness to save indoor space.
|
| Standard Thickness | 9.5mm / 12mm / 15mm |
| Customization | Available in custom sizes per customer requirements |
