When a Buddhist community in Dallas started making plans for a new temple, cafeteria and dormitory, they wanted to create the healthiest and most ecological buildings possible. Inspired by the work of EcoNest® Company, they decided a mixture of straw and clay would be their primary building material.
While this combination is ideal for shaping and insulating walls, they also needed a product that would create a strong, durable and dry foundation (and, for the two-story dorms, strong bearing walls). They selected Faswall, a versatile ICF wall form that’s ideal for many types of projects. While Faswall’s easy-to-use blocks can be used to create DIY or contractor-built homes, office buildings, warehouses, outbuildings and other structures, they also make great foundations and basements for buildings crafted from other materials.
The leadership team in the Buddhist community liked Faswall because the concrete and wood blocks are made of 100 percent organic materials. Eighty-five percent of the wood in each Faswall block is clean, recycled pallet wood. It’s combined with virgin wood and Portland cement to create a product that will not off-gas chemicals into buildings.
“Many of our customers are interested in using the Faswall block to create healthy living environments,” says ShelterWorks co-owner Paul Wood. “They want indoor air quality that’s exceptional. Faswall creates an excellent vapor-permeable membrane that allows indoor air quality to be a natural part of the building and living experience.”
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.
The other reason is that their mineralized wood composition makes them strong and durable. Faswall gives people building with straw bale, timber frame or clay/straw slipform a good base wall system to support upper walls.
The Dallas project isn’t the only time Faswall has been used to build a Buddhist temple. Check out this story and video of the Sravasti Abbey in Washington to see their beautiful structure, which is built entirely with Faswall blocks. Other religious congregations have also selected Faswall as their building material of choice.
Perhaps that’s not surprising. Faith helps comfort us in times of despair, celebrate in times of joy, slow down and reflect on the things that are important to us. Just as a belief system is a versatile tool for living, Faswall is a versatile tool for creating the places that nurture and protect us.
No matter what type of structure you’re thinking about building – and no matter what type of material you’re thinking about using – Faswall can play a role in your next project.

For years homeowners, contractors, architects and material manufacturers have focused on “green building,” or constructing homes and businesses that have less of an impact on the planet. But more and more, they’re moving away from the term green building in favor of “high performance building.” Industry experts believe this phrase does a better job of explaining the myriad goals they hope to meet, including lowering a home’s carbon footprint, saving the owner money on energy bills, and creating a structure that will last for a long time.
Since the term high performance building is so new, there’s still a lot of confusion about it. What does high performance building mean? Why is high performance building better than green building? How do you build a high performance home, office, warehouse or other structure? We’ll explore these questions in more depth.
The National Institute of Building Science defines high performance building as creating structures that “integrate and optimize all major high-performance building attributes, including energy efficiency, durability, life-cycle performance and occupant productivity.”
That’s a bit of a mouthful. Let’s break it down.
Energy efficiency is one of the most important parts of high performance building. Decreasing your home’s energy usage is important for many reasons. In the United States, electricity production is the largest contributor to climate change, creating 31% of our total greenhouse gas emissions. Forty-one percent of all the energy Americans produce is consumed by residential and commercial buildings. If people can significantly lower the amount of energy needed to power their homes, they can make a big difference in the fight against climate change.
Increasing your home’s energy efficiency can help you save money on your utility bills, and get you closer to the goal of living partially or completely off the grid. For people interested in homes that utilize net zero, Passive House or passive solar principles, building an energy efficient structure is a must.
Durability is another important component to a high performance home. When you construct a building that will last for a long time, all the energy and materials that went into making it remain there. From an environmental perspective, saving the embodied energy of the home is vital because it keeps materials out of landfills and decreases the amount of new materials that have to be harvested, mined and processed. The longer a home stands, the longer you can retain that embodied energy.
The average high performance home is designed to last for up to 200 years. Because it’s built to such high standards and with such quality materials, it’s better able to withstand natural and man-made hazards such as severe weather (hurricanes, tornadoes, tsunamis, etc.) and wildfires. If you’ve ever dreamed of having a house you can pass down to your children and grandchildren, building a high performance home will help you fulfill that dream.
Having good life-cycle performance means the home meets all the owner’s goals (no or low utility bills, lower maintenance costs, good indoor air quality, etc.). It does that now and into the future. A high performance building should be built well enough and smart enough that it doesn’t require a lot of time or money to maintain. Not only is it made with high quality materials, it utilizes the best in building science to reduce mold, rot and other problems. Some examples of smart building science include looking at a building’s envelope, thermal mass, materials, heating and ventilation systems, and defense against rain and the natural elements.
We believe occupant productivity comes down to the health and comfort of the people who live and work in the building. One of the biggest considerations for a healthy home is good indoor air quality. In older homes, air and moisture have many places to enter the house, but few places to escape. As a result, the air is full of dust mites, mold, bacteria, pollen and other allergens. It’s estimated that the air quality inside a typical home is two to five times worse than the air quality outside. That’s concerning because Americans spend 90% of their time indoors.
In high performance homes, the interior air is continually exchanged with outside air that has been filtered and tempered. That means mold is less likely to form inside the walls, allergens and pollutants don’t enter the home, and you and your family have a healthy, pleasant living environment. High performance homes are also built with non-toxic materials that will not off-gas formaldehyde, phthalates, VOCs, flame retardants and other harmful substances into the house.
Another way high performance homes increase occupant productivity is by providing a high level of comfort. All the building science involved in creating high performance homes means structures have a consistent interior temperature, no drafts and very little noise. They are clean, full of light and smell good.
In addition to the four attributes described above, we would like to add that high performance homes are built with what we’ve come to know as green building materials. Green building materials contain recycled materials, are easy to recycle at the end of their lifecycle, have a minimal negative impact on the planet when they’re harvested and manufactured, and/or don’t contribute to bad indoor air quality.
High performance buildings should also be aesthetically pleasing and functional for the homeowner. If a building meets all its goals in terms of energy efficiency and occupant productivity, but it’s ugly or has a bad floor plan, no one will want to live there. It increases the likelihood that the building will be torn down at some point.
If you’re looking for the perfect building material for your high performance home or office, Faswall is an excellent choice. Faswall ICF wall forms create structures that are extremely energy efficient thanks to their high thermal mass.
Faswall is made with a blend of recycled wood and concrete, which makes the blocks extremely durable. Homes can last for well over 200 years. The mineralized wood composition ensures Faswall resists pests and will not mold or rot. Wood and concrete are completely organic materials that will not off-gas into the house.
The interior and exterior of a Faswall home, office, church, outbuilding or other structure can be finished any way you want. As you can see from the photographs, the structures look beautiful when they’re done. Faswall blocks are easy to work with, whether you’re an experienced contractor or a DIY home builder.

If you’re a DIY builder thinking about building your own home, you don’t have to take our word that Faswall green building blocks are perfect for do it yourself homebuilders. Many of our customers have provided excellent feedback over the years.
Dick and Kathy Hartman used Faswall green building blocks to build their own home in rural New Mexico. The gorgeous stucco structure has stone details, a metal roof and wide window wells on the inside. (All the photos in the post come from Dick and Kathy.)
Here’s what Kathy has to say about Faswall:
“We LOVE our home. We were able to do the floor plan and build the way we wanted. We worked together to build our outside walls. This saved us a bundle in labor and it was fun watching the walls go up.
“Now that we are living in our new home, the heating and cooling is very efficient! I’ve had my air on 74 degrees all summer (and we have been in the low 100’s). Our house has been very comfortable! Now that it is getting cooler I have not changed the air temperature, but we are heating very little with a pellet stove or our wood stove.
“The house is absolutely beautiful. Everyone who comes is in awe! Thanks for such a great product!”
Rob Story of Washington also had a great DIY homebuilding experience with Faswall green building blocks. His 1,200 square foot house with a 1,000 square foot office also has a metal roof, stucco exterior and many features he and his wife love.
Rob built his own home when he lived in Hawaii, but he definitely didn’t consider himself an expert builder. Still, he says, he found his experience with Faswall “excellent, exciting, fulfilling and rewarding.
“As my wife and I considered what type of home to build, we also had to decide what to build with,” he says. “Our number one requirement was warmth. We also had deep interests in low environmental impact, longevity of structural integrity, energy efficiency, ease of building and aesthetics. I had firm wants with the materials I was going to use: no drywall, no foam, no plastic vapor barrier, no crawl space and no glass insulation with formaldehyde.”
A friend told him about Faswall and he was intrigued. “I called ShelterWorks and started asking questions,” Rob says. “They took ample time with me and answered my questions. As it became clear to me that Faswall was the way I wanted to go, my wife and I scrapped our design and did our last re-design using Shelter Works suggestions. That helped lessen the materials we needed and saved some money. We placed our order and away we went.
“Everything went great. Our blocks came right on schedule, block counts were accurate, telephone support was available and the material quality was very consistent. I was very surprised how fast the structures went up. Once the slabs were poured, we began stacking blocks. It took four of us two weeks to stack, brace, plumb and pour both structures.
“Heat retention in the winter has been great. We sit inside as the Northwest winds howl and feel cozy and safe in our strong and sturdy home. People come by and marvel at our place. I’m happy to tell them about it because I really feel that we made the right decision to build with Faswall. There is not another material that would serve us better in the long run.”

Coleman Pulsifer built his first home and helped several of his friends in rural Maine do the same. He enjoyed it so much he went on to work as a professional carpenter, building homes for others for many years.
When their first grandchild was born, Coleman and his wife Susan dropped everything to move to California and be closer to the little boy. They bought the parcel of land adjacent to their daughter and son-in-law’s property, and Coleman returned to his roots as a DIY homebuilder. His two-bedroom, one bathroom home in California’s Humboldt County was constructed with Faswall green building blocks, an ideal material for DIY home builders.
Coleman and Susan wanted a small home they could finance themselves, build themselves and keep completely off the grid. They acquired a small parcel of land that presented opportunities and challenges for building. It was a beautiful site with a large hill, which meant part of the home could be earth sheltered and the rest could be open to spectacular views.
However, winds in their area can reach up to 90 miles an hour. Temperatures top 100 degrees regularly in the summer. California is likely to experience a major earthquake at some point, and wildfires present a new challenge to anyone looking to build in the rural west. The Pulsifer’s new home needed to be durable enough to withstand everything nature threw at it.
Coleman first learned about Faswall green building blocks at Organic Grace, a northern California store that sells products for healthy and non-toxic living. “It was obviously well designed and easy for DIY builders to work with,” he says. “Its insulative value was appealing. A surface texture that allows you to stucco and plaster was wonderful.
“A lot of standard ICFs are made out of Styrofoam. When you want to stucco, you have to do a whole other procedure for preparing it. With Faswall, after you’ve poured the wall you can finish them. The surface texture is excellent for plastering. It saves some time and some steps.” Plus, he says, his old home in Maine had Styrofoam insulation that attracted ants.
Coleman was able to build nearly the entire home himself, with Susan and their son-in-law pitching in when needed. The finished building measures 33 feet by 35-feet, giving it about 1,100 square feet on the main floor. A lower level has a studio and storage space. A metal roof has a full rain catchment system that supplies an above-ground swimming pool for the Pulsifer’s grandson and a fire suppression system.
All the power in the home comes from a 200 watt solar panel. To keep their energy usage down, Coleman included a gravity-fed water system and a root cellar in the house. That, combined with ice chests, is enough to preserve all their food. “We haven’t had a fridge for four years,” he said.
The lack of power also means no air conditioning. That’s where Faswall’s superior thermal mass comes in handy on scorching summer days. “When you’re down in the studio, it can be 105 degrees outside and it can be 80 degrees inside,” Coleman says. “It’s exciting how well the building performs.”
“I liked the fact that you could work with it with carpentry tools,” he says. “You have flexibility to fine tune things if you need to. If you’re going along and decide to move a window, you have that opportunity. You don’t have to be rigidly locked to one-foot increment.”
“The amount of steel reinforcement we put in made me feel much more confident, especially since we’re in an earthquake zone,” he reports. The chambers within Faswall green building blocks make it easy to insert rebar vertically into buildings. Those pieces can be tied in with the horizontal rebar placed between the blocks to give the building extra strength.
Coleman has several pieces of advice for do it yourself home builders who want to build their own home with Faswall green building blocks. “Part of the reason Faswall works so well is that it’s permeable,” he says. “It survives out in the rain perfectly fine, but it does allow moisture to go through. I would counsel people to be very conscientious about perimeter drains.
“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.” Faswall’s experienced construction consultants can help you include these features so that you home stays safe and moisture-free.
For anyone building their own home and trying to live in it at same time, Coleman offers a word of caution. “Fifty percent of couples break up during building projects. You’re living in a place that’s full of dust and insulation, that’s incomplete but also full of dreams and anticipation.”
He and Susan lived in a military surplus tent while they completed the downstairs. They stayed in the studio while they finished the upper level. They found it vitally important to keep the upstairs a worksite.
“If you have to clean up every day, you lose a lot of time,” he explains. It’s tiring, frustrating and means living in a construction zone that much longer. Instead, he and Susan taped up plastic sheeting and took other steps to contain the dust and debris littering the upstairs portion of the building.
Now that the home is finished, Coleman and Susan couldn’t be happier with it. They have no debt, and they have a low cost, low maintenance home they love.

Terry Davenport with Natural Housebuilders in Montana is a new convert to Faswall green building blocks. Terry specializes in building highly energy efficient homes that use the sun for heat. He’s employed a number of solar passive and solar active techniques to create high-quality homes in the Bitterroot Valley and Missoula area.
ICF wall forms such as Faswall green building blocks were not really on Terry’s radar screen because he didn’t think they had a high enough R-value. He preferred to use foam blocks for their great insulation value.
But when a girlfriend asked Terry to build a house for her, he started looking into Faswall green building blocks and decided they might be a better fit. He liked that Faswall were made from 100% recycled pallets rather than petroleum like the foam blocks. He appreciated that company owners Paul Wood and Paul Van Denend were always honest and straightforward in working with him.
Terry also came to understand that Faswall’s superior thermal mass properties could help him get achieve the warmth and comfort he seeks to provide customers when he builds or remodels a home for them. On cold days, any heat from the sun or heaters is retained by the Faswall blocks and released into the home at night. On hot days, the heat is absorbed during the day and given off slowly at night, when temperatures are cooler. Those properties mean homes are extremely energy efficient and inexpensive to heat and cool.
The realization of how thermal mass could benefit homeowners was cemented when Terry was on a backpacking trip in Montana. “At the end of the day, you start looking around and that big rock is always warmer than anything else,” he says.
Terry’s girlfriend approved the use of Faswall blocks, and the two got to work building her 1,000 square foot home on the Flathead Indian Reservation. She took great pride in the fact that she hauled all the blocks to the building site in a wheelbarrow, and that she could help build her home herself. “I like the fact that the homeowner can work with me,” Terry says. “It’s pretty easy to stack thing together” – much easier than framing, where everyone involved has to understand things like correctly measuring window dimensions and the proper way of attaching boards together. The ease of using Faswall green building blocks means that they are perfect for even DIY home builders.
When you build a timber frame house, Terry says, you spend a lot of time hunched over as you construct the pieces that run along the ground. With Faswall green building blocks, Terry says he spent a lot more time standing straight up, which was much easier on his back. “When you get older you start thinking of ways to make things easier on your body,” he points out.
In addition to building one bedroom, a loft that doubles as a second bedroom and a massage room, and one bathroom, Terry added a greenhouse onto the side of his girlfriend’s home so she could keep a small garden. The home’s windows are made from post-manufacturing recycled materials, and the balusters on the staircase are made from recycled rebar left over from installing the cement floor.
Terry tacked 5¼” foam bead board on the side of the house, which helped it achieve an extremely high R-value of 41. Between Faswall’s superior thermal mass properties and the added insulation, the homeowner only needs one cord of wood to heat the entire home through a cold Montana winter.
The homeowner is thrilled with the house, as is Terry. His interest in finding new, innovative building materials dates to his early days as a motocross racer, he told Distinctly Montana magazine in a recent interview. He and his friends were always tinkering with their motorcycles to try and improve their performance. Over time he shifted his focus from motorcycles to houses.
“I still feel spoiled because I get to learn about the greatest new technology for homes,” he says. But of all the home building materials he’s found over time, Faswall green building blocks is one of the ones he plans to stick with. We look forward to working with Terry on many more projects.
