Construction Boards – Clay Boards, Fermacell Gypsum Fiber Boards, or Wood Fiber Boards
The choice of construction materials is crucial as it directly impacts the functionality, durability, and environmental and health effects of a building. Thoughtfully selected materials help ensure energy efficiency, improve living quality, and extend the building’s lifespan. This is particularly important in modern construction, where eco-friendliness and health are at the forefront. Clay boards, gypsum fiber boards, and wood fiber boards are three materials that not only meet these criteria but also offer versatile and innovative solutions for various projects, ranging from new constructions to complex renovations. In this article, we will explore the key properties, advantages, and applications of these materials.
Clay Boards – A Healthy and Natural Solution
Applications of Clay Boards
Clay boards are entirely natural construction boards popular among advocates of ecological construction. These boards are highly versatile and particularly suitable for:
Covering interior walls and partitions: Known for their exceptional moisture regulation and heat accumulation properties, clay boards create a healthy and balanced indoor climate. They are also durable and aesthetically pleasing, fitting well with various finishing styles.
Ceiling coverage: Clay boards allow for aesthetically appealing and functional ceiling solutions, improving room acoustics and reducing echo.
Renovation projects: Thanks to their versatility, clay boards are ideal for renovating historical buildings. They preserve the authentic appearance while offering modern advantages like better thermal insulation and moisture management.

Advantages of Clay Boards
- Healthy indoor climate: Clay’s natural moisture-regulating properties ensure that rooms do not become excessively dry or damp.
- Natural sound insulation: Clay boards improve room acoustics by reducing echo from furniture and conversation.
- Eco-friendliness: Clay is a renewable and recyclable material that reduces the ecological footprint of construction.
- Aesthetic versatility: Various finishing techniques can create unique, nature-inspired, and modern design solutions.
- The use of clay boards ensures a healthier and more sustainable living environment, making them particularly suitable for people with allergies or asthma.
Fermacell Gypsum Fiber Boards – A Durable and Versatile Solution
Applications of Fermacell Boards
Fermacell gypsum fiber boards are made from gypsum and recycled paper, combining the best properties of these two materials to provide an ideal solution for a variety of construction projects. These boards are designed to meet the highest standards of modern construction and are suitable for:
- Building walls and ceilings: Perfect for both new constructions and renovations.
- Creating fire-resistant surfaces: Used in areas with higher fire safety requirements.
- Soundproofing: Improves acoustic comfort by reducing noise on both sides of the wall.
Advantages of Fermacell Boards
- Fire resistance: The material meets the highest fire safety standards, making it ideal for secure construction.
- Moisture resistance: Unlike standard gypsum boards, Fermacell boards tolerate moisture, making them suitable for bathrooms and kitchens.
- Multifunctionality: Fermacell is both strong and flexible, offering high load-bearing capacity.
- Environment and health-friendliness: The boards are free of harmful substances, providing a cleaner and safer indoor environment.
These qualities make Fermacell an excellent choice for complex projects that require a combination of durability and aesthetics.

Wood Fiber Boards – Natural Insulation and Soundproofing
Applications of Wood Fiber Boards
Wood fiber boards, made entirely from natural wood fibers, are valued for their versatility, thanks to their unique properties and wide range of applications. These boards offer excellent thermal and sound insulation while helping create a healthy and energy-efficient indoor environment.
They are suitable for:
- Insulating walls, ceilings, and floors: Keeps buildings warm in winter and cool in summer.
- Soundproofing: Reduces noise transmission, enhancing acoustic comfort in both residential and work environments.
- Impact noise reduction: Ideal for multi-story buildings where impact noise is a concern.
Advantages of Wood Fiber Boards
Thermal efficiency: Helps reduce heating and cooling costs, improving building energy efficiency.
Eco-friendliness: Made from renewable materials with low-energy production processes.
Moisture regulation: Keeps the insulation layer dry and prevents moisture damage.
Prevention of thermal bridges: Helps avoid heat loss, improving the building’s indoor climate and energy efficiency.
The flexibility and efficiency of wood fiber boards make them indispensable for both eco-friendly and performance-oriented construction projects.
Which Construction Board to Choose?
The choice of construction board depends on the specific purpose of the project:
For a healthy indoor climate and natural material, clay boards are an ideal choice.
For a strong and versatile solution, Fermacell gypsum fiber boards are an excellent option.
For eco-friendly and efficient insulation, wood fiber boards are the preferred choice.
