Green Rhino Withstands The Heat
The Green Rhino foam coated with it’s “Special Sauce” concrete high strength membrane is a force to be reckoned with. Even with a roaring 1.800 degree gas fire in the corner and a 3,000lb loaded ceiling GRBS stood strong and passed the INTERTEK fire test with flying colors.
Testing The GRBS
To get where we are today Green Rhino has had to undergo extensive testing at numerous different facilities across the South West and West Coast. We are currently in the final stages of receiving our ESR number, and once we do we will be cleared to ship and use GRBS anywhere in the world.

New River Builder Goes To The Wall For Energy Savings
Don’t be fooled by the appearance of Dan Dwyer’s New River home. It looks like other custom Territorial-style homes, with massive walls, an earthy brown exterior and a stuccolike finish. But that’s because you can’t see inside the walls. The secret to Dan Dwyer’s super-energy-efficient Territorial-style home lies within the 8-inch-thick walls: a combination of insulating concrete forms and insulated panels. The front porch takes in New River’s hilly scenery.
Instead of wood framing, Dwyer, a custom builder who specializes in green construction, used what he calls the Dwyer Alternative Building System when constructing the 2,800-square-foot house. It is a combination of two foam building systems – insulating concrete forms and a custom insulated panel product called Macrotherm. They then are coated with a concrete shell, called glass fiber-reinforced concrete, inside and out.
The result is a super-insulated structure that has 8-inch exterior walls with a higher insulation factor of R-40 to R-60 and ceilings that are rated R-80 to R-100, Dwyer said. Typical construction calls for R-19 to R-23 walls and R-30 ceilings. Dwyer’s home also features roof overhangs, which shield the interior from the sun, a hot-water recirculating system and dual-pane windows.
The home’s ultra energy-efficiency meant that Dwyer could downsize the heating and cooling system and still have a comfortable house. The utility bills are about half what they are for typical homes of the same size, he said.
Dwyer, who has been building green homes since the early 1990s, and two helpers spent nine months constructing the house, which sits on 1 1/4 acres on a hillside. Unlike other homes, it doesn’t contain drywall or a concrete slab. Even the foundation is made of the foam system, then covered with a tongue-and-groove subfloor.
The exterior walls were easy to put together, said Dwyer, who lives in the house with his two sons and who is trying to spark interest in the building method. His company is Dwyer Custom Homes Inc.
“The real key is the bond between the foam panels,” he said. He used special adhesives that don’t disintegrate.
The foam building product is easy to carve, meaning that custom features, such as niches, are easy to construct compared with typical methods. In his home, Dwyer created a stair-stepped, coffered ceiling that added drama to the dining room and an impressive barrel ceiling in the kitchen.
When one of his sons requested a window seat in his bedroom, the builder took the concept one step further by creating a nook the size of a queen bed out of the foam system. Wired for sound, the nook is the perfect place for playing computer games.
The home has other decorative features. The kitchen has a modern Southwest look that’s highlighted by dark Mission-style cabinetry, rough-edged granite counters and dark ceiling beams, set in a cross shape and made of knotty pine, an eco-friendly, renewable resource.
The focal point of the great room is the enormous fireplace/entertainment center that Dwyer constructed of stacked stone. The master bedroom features a rustic wood bed frame, which is set at an angle and is covered in white bedding.
Throughout the house, hand-scraped hickory floors lend a custom look. All interior walls and ceilings are covered in Venetian plaster.
The decorative plaster, which requires a steel trowel to smooth, was a challenge to install. “It sets up in 20 minutes,” Dwyer explained.
In most rooms, the plaster is a rich gold-tan. In the dual-vanity bathroom that the two sons share, the builder opted for chocolate brown, a perfect backdrop to the granite countertops that are in gold and black.
The front porch was an afterthought, but it’s perfect for gazing at the hilly scenery.
Part of the property serves as a construction test site for the building system, which Dwyer has used in several other projects.
“The fun for me is in building, in seeing it come up from the ground,” he said.
