Faswall® blocks are revolutionizing the way homeowners think about sustainable construction. As an innovative alternative to traditional concrete blocks, these eco-friendly building materials offer a unique blend of durability, energy efficiency, and environmental consciousness.
Homeowners looking to build or renovate their house with a focus on sustainability and long-term value will likely find Faswall® blocks an intriguing option and one they may want to explore further.
What are Faswall® Blocks?
Faswall® blocks are similar to insulated concrete form (ICF) blocks, which are popular in green building circles. Unlike traditional wood-frame construction or standard concrete blocks, Faswall® blocks consist of 85% mineralized wood and 15% cement, which puts them among the most environmentally friendly building materials available.
They’re lightweight yet sturdy, typically measuring 24 inches in length according to the Faswall® company website. Their modular design includes an interlocking tongue-and-groove system, allowing for easier stacking and assembly during construction.
Faswall® blocks are also breathable, leading to better moisture regulation within walls, and they offer superior impact resistance and durability.
What Are the Benefits of Using Faswall® Blocks?
Faswall® blocks have numerous advantages for homeowners and builders, including:
Environmental Impact
One of the most significant benefits of Faswall® blocks is their minimal environmental footprint. By using recycled materials, these blocks reduce waste and conserve natural resources. In addition, their long lifespan means less frequent replacements and renovations, further reducing environmental impact over time.
Energy Efficiency
Faswall® provides excellent insulation for homes thanks to its high thermal mass. The blocks absorb and slowly release heat, helping maintain consistent indoor temperatures. This can lead to significant energy savings.
Durability
Structures built with Faswall® blocks are designed to last for centuries. Being resistant to rot, insect damage, and fire, they’re an excellent choice for homeowners looking for a low-maintenance, long-lasting building material. The blocks can also withstand severe weather conditions, including hurricanes and moderate earthquakes. This adds an extra layer of security and, in all likelihood, more peace of mind.
Versatility in Construction
Faswall® blocks can be used in various construction projects, from residential homes to commercial buildings. Their adaptability makes them suitable for:
- Residential construction: These building materials are ideal for single-family homes, passive solar designs, basement construction, and garden bed kits. Their thermal properties make them particularly well-suited for energy-efficient home designs.
- Commercial and institutional buildings: Faswall® blocks excel in larger-scale projects, such as schools, universities, hospitals, healthcare facilities, chemical laboratories, and storage areas. Their fire resistance and durability make them an excellent choice for buildings that require high safety standards and low maintenance costs.
- Agricultural applications: Farmers and gardeners can benefit from Faswall® blocks when building greenhouses, root cellars, and livestock housing. The blocks’ ability to regulate temperature and humidity makes them ideal for agricultural structures where specific environmental conditions must be maintained.
Improved Indoor Air Quality
The composition of Faswall® blocks helps regulate indoor humidity levels, reducing the risk of mold growth and lowering the need for dehumidifiers. These blocks are also non-toxic, so they offer better indoor air quality than some synthetic building materials can provide.
Ease of Use
Faswall® blocks are lightweight, making the construction process less labor-intensive for workers. They don’t require mortar, and, thanks to their interconnecting tongue-and-groove end design, are relatively easy to stack when creating walls. Crews also find that rotary and oscillating cutting tools can easily penetrate and cut the blocks.
Cost Considerations for Faswall® Blocks
The initial investment in Faswall® blocks can be higher than the cost of some traditional building materials, but Faswall® blocks tend to be less expensive than ICFs. The potential for energy savings and reduced maintenance can also offset costs over time.
In the United States, Faswall® blocks typically range in cost from $12.50 to $15.40 per square foot. This price will often vary depending on project location, specific design requirements, and market conditions.
To get an idea of the possible construction cost under a few scenarios, check out the data in this table made by Faswall®.
| Building Size in Square Feet | Estimated Square Footage Needed in Faswall® Blocks | Estimated Overall Price, With Shipping |
| 1,500 (single-story house) | 1,375 | $17,100–$21,100 |
| 2,000 (ranch-style house) | 1,887 | $22,800–$26,800 |
| 4,000 (two-story house) | 3,325 | $40,700–$48,700 |
Challenges Presented by Faswall®
While Faswall® blocks offer several benefits, homeowners and builders should be aware of potential challenges associated with their use.
The Need for Extensive Planning
Faswall® blocks can require adjustments to traditional building plans. The blocks’ thickness can impact room dimensions, framing methods, and overall floor plans. Architects and designers may also need to adapt their usual approaches to accommodate the blocks’ unique size.
Specialized Construction Processes
When using Faswall®, contractors need training or experience with ICF systems as well as access to specialized tools and equipment. As a result, the construction process can take longer than planned as teams adapt to working with the material.
Water Infiltration Risks
Water infiltration is a concern during and after construction. Water can seep into the lining between the blocks or near window and door openings. Builders need to use extra peel-and-stick protective layers to waterproof the building, making for a complex process that can raise your costs.
Should I Use Faswall®?
When deciding whether to use Faswall® blocks, a few other factors are also worth keeping in mind.
Climate Suitability
Faswall® blocks are particularly well-suited for certain climates. Their thermal mass properties make them excellent for regions with significant temperature fluctuations from day to night. In these climates, the blocks can stabilize indoor temperatures, reducing the need for mechanical heating and cooling. However, in mild climates, the benefits of Faswall® blocks’ thermal mass may be less noticeable.
Local Building Codes and Regulations
Before starting a project with these blocks, you’ll need to consult local building codes and regulations. While they comply with many building standards, specific areas can have unique requirements. Being sure your project adheres to these regulations can prevent costly changes and delays during construction.
Supplier Availability
The availability of Faswall® can vary depending on your location. Shipping costs and timeframes can impact the overall project budget and schedule. To streamline the process, seek multiple suppliers or consult nearby contractors who are experienced in working with Faswall® blocks.
Potential Resale Value
Homes constructed with Faswall® can have a higher resale value due to their durability and energy-efficient properties. When marketing a house built with these eco-friendly materials, highlighting the long-term benefits and cost savings can attract environmentally conscious buyers willing to pay a premium for sustainable construction.
Final Thoughts About Faswall® Blocks
Faswall® blocks represent an innovative approach to sustainable home construction, and this approach aligns with the growing demand for eco-friendly building solutions. While Faswall® blocks come with some challenges, their long-term benefits in the areas of energy efficiency, durability, and environmental impact make them a compelling choice for many homeowners and builders.
