Walk inside the New American Home (TNAH) 2017 and a couple steps beyond the entry area you find yourself outside again.
There’s a courtyard with a putting green and palm trees inside this 8 753-square-foot, single-story dwelling built on the same street as the homes of pro golfers Henrik Stensons, Sergio Garcias and Ian Poulters in the gated community of the Lake Nona Golf & Country Club.
Three of the five bedrooms line one side of the artificial turf. Directly across, a great room opens into the back yard with a pool, summer kitchen, game room and a spa and steam room. The master bedroom is by the spa and there’s a guest suite with its own family room.
Built by the Phil Kean Design Group, TNAH takes full advantage of its location by the lake with large windows and sliding glass doors. Breezeways and hallways connect the different parts of the house, where unused rooms can be closed off, for a layout style called “pod living.”
The design team also takes advantage of the Florida sun with solar panels on the roof meeting all electrical needs while a system of nine propane-fuelled tankless water heaters satisfy all hot water needs.
While not among the obvious amenities, plastic building materials play important roles in creating an exterior envelope that is so tight, energy use is minimised and pest control is maximised. The builders used a new open-cell spray foam by Icynene Inc. that is low in volatile organic compounds, which improves indoor air quality while boosting energy efficiency, as well as a tough new insect barrier wrap by Polyguard Products Inc. called Term.
Plastic keeping bugs at bay
Polyguard CEO John Muncaster said the wrap, which was developed with entomologists at Texas A&M University, has a thick polyethylene backing to keep bugs, particularly termites, at bay. The top layer is made of a polypropylene fabric so concrete can bond with the fibres if it’s used as a barrier for the underslab, which is a common entry point for subterranean termites. A proprietary sealant is used to hold the plastic fibre and film together.
“This has been tested long term in the lab and in the field and it resists termites,” Muncaster said. “We don’t why. We don’t know everything about what makes them tick.”
The combination of the sealant and two plastics simply can’t be penetrated by voracious-eating termites. The three materials seem to have sound-deadening qualities for the insects, and that could be factor, Muncaster said, or it could be related to the barrier’s odor and moisture control.
“We’re putting the house in a sealant bag, really,” he said. “Not only the bottom, where so many insects come in, but up the walls at the seams there can be openings. Our goal is to seal all gaps wherever possible. You can almost keep all insects out.”
In new construction, if incorporated into the design stage, the Term system can seal plumbing openings, bath traps, base flashing, window flashing, vent holes, flooring underlayment and joints in addition to foundation and underslab barriers. No system can keep out every bug, but this one comes close, Muncaster said.
In remodelled houses, the Term system can protect sill plates, seam and window flashing, underlayments for replaced floors, and more if it’s a major renovation.
“We think it has the potential to take sustainable construction up another level and help people live better and more comfortably,” Muncaster said, noting that water and energy conservation have long been goals of green builders. “We’ve got something new. I don’t think anybody in America has ever taken a systems look at construction to exclude insects and other pests. That’s what we’re doing.”
