Wet Climate Performance
Faswall holds up great in wet climates
Faswall green building blocks are also able to stand up to very wet conditions. Tom Bristol of Purple Flattop Architecture in Chewelah, Washington was dubious about just how much the wood/concrete IFC wall forms would be able to resist water. He decided to run a test of his own.
Tom took a Faswall block and dropped it in a bucket of water. And left it there for 10 years.
The result? The Faswall green building block has seen little to no deterioration over that time.
Now, we’re certainly not recommending you build your home by a flood plain, a beach frequently ravaged by hurricanes or tsunamis, or an area prone to forest fires. But should disaster strike – which is more likely as climate change continues and the world’s weather gets more unpredictable – Faswall green building blocks will give you more reassurance that your home will last and stay safe.

Resists Mold - Breathability is Key
"Breathable" = Healthier and More Comfortable
Unlike foam ICF’s Faswall® is vapor permeable, which eliminates moisture and mold for your long-term health and decreased maintenance.
Relative Humidity is Kept Low
The vapor-permeable nature of the blocks is important when it comes to other factors that affect indoor air quality. Because of Faswall’s porous hygroscopic nature (i.e. the walls store and release water vapor through diffusion), the blocks keep relatively humidity levels low enough that mold spores don’t grow in the walls. That keeps potentially toxic mold out of your building.
Faswall’s ability to regulate relative humidity also keeps the structure more comfortable and livable. Most of the time, humidity is higher inside a home due to activities such as showering, cooking, even breathing. When a home has walls that don’t breathe, and therefore relies on mechanical ventilation to vacate moisture, the indoor air can become denser than the desired 30 to 40 percent humidity level. That leads to the heavy-feeling air we often experience in basements.
Faswall’s porosity allows excess indoor humidity to diffuse through the walls. With proper waterproofing, they don’t allow water to seep into structures. That’s why they’re great for foundations.
“The drainage and grading work around the foundation is also very significant, especially in a place that get lots of rain,” Coleman says. “Pitch the finished grade so that surface water flows away from the house. Do careful backfilling. Don’t slack off on it.”
Prepare Your Foundation for Drainage
Faswall’s experienced construction consultants can help you include these features so that you home stays safe and moisture-free.
“We did a lot of research on various green building systems but settled on Faswall. Not only did it seem like the “greenest” technology, but the ease of building compared to other systems seemed like a good choice for an owner/builder. What we didn’t expect, but were totally delighted with, was how knowledgable and helpful the people at Faswall were. We couldn’t have done it without you!”
