FAQ

We manufacture our products using the same production processes and quality control standards as in Japan. However, thickness, dimensions, and certain specifications are tailored to suit Vietnamese culture and practices.

Not only our Moisture Boards, but even our Regular Boards contain anti-mold agents. High dimensional accuracy is also a key feature of Yoshino’s products.

Gypsum boards provide soundproofing and sound insulation, helping to create a quiet and comfortable space. Specific installation techniques are required for enhanced sound insulation. Please contact Yoshino staff for further details.

Gypsum boards have low thermal conductivity, offering thermal insulation benefits. Compared to other building materials such as plastic boards, gypsum boards are more effective in blocking external heat and improving air conditioning efficiency.

Compared to the imported versions, our current boards are much lighter and more flexible. We have enhanced the workability of the boards - making them lighter and easier to bend - without compromising their original quality and performance. We invite you to experience the difference.

Gypsum boards possess humidity control (moisture absorption and release) functionality. When humidity is high, they absorb moisture; when humidity is low, they release it—helping to maintain a stable indoor humidity level.

The Regular Board does not contain glass fibers. Only the Fire Resistance Board includes glass fiber.

The Moisture Board has a special waterproof treatment and is recommended for use on ceilings and walls in areas with high humidity and the potential for occasional splashes, such as kitchens, washrooms, and toilets.

The effective duration varies depending on the amount of harmful chemical substances (such as formaldehyde) in the environment. Based on calculations, the effect can last for over five years in some cases (this is not a guaranteed value). The absorbed harmful substances are decomposed into harmless compounds inside the Hi-clean Board and are therefore not re-released into the air.

The decomposition agent used for harmful substances is stable, so its performance does not degrade even after long periods of storage.

We have obtained a Technical Evaluation Certificate from the Building Center of Japan (BCJ). Our technology has been recognized for significantly reducing harmful chemicals and environmental impact compared to standard gypsum boards.

When harmful substances build up at high concentrations in the space behind walls or ceilings, they may seep back into the room. The Hi-clean Board helps prevent this and reduces the indoor concentration of harmful chemicals. It also absorbs and decomposes pollutants released from furniture or other sources, contributing to a safer and more comfortable indoor environment. However, depending on the type of wallpaper or paint used, direct absorption may be limited. Therefore, we recommend using breathable finishing materials whenever possible.

The product name (e.g., Hi-clean Board, Fire Resistance Board) is printed on the back of the board, allowing you to distinguish between them at construction sites.

The strength, fire resistance, dimensional stability, and ease of installation are the same as those of the Regular Board.

Yes, we manufacture and sell “ Fire Resistance Boards,” which are specially developed to enhance fire resistance, available in 9.5mm, 12.7mm, and 15.9mm thicknesses.
