ThermalCore panels moderate interior temperature fluctuations and act as a thermal mass.
Agriboard SIPs utilize agricultural waste, wheat, and rice straw as an insulating core. More than 80% of Agriboard’s panels consist of straw left over after the grain has been harvested. The perimeter LSL presents a high shear-strength panel with virtually no thermal bridging. The 7?7/8-inch-thick panels have a dynamic R-value of up to 25.4. Any straw waste from the construction process can be reused as landscape mulch. 866.247.4267.
Made just like a SIPs panel, E-Rim Insulated Rimboard consists of a sandwich of OSB and polyurethane foam, providing a tightly sealed, R-14 barrier around the beltline. According to the firm, the product is 20 times more airtight than conventional rimboard, and tested thermal performance is 12% better than a conventional system. E-Rim is available in all standard floor joist sizes. 866.363.7267.
The company’s structural insulated panels use the chemical HFC 245fa as a blowing agent in their polyurethane SIPs. HFC 245fa has a zero Ozone Depletion Probability (ODP), a low Global Warming Potential relative to other refrigerants, and is not considered a VOC. The manufacturer claims the OSB is made from fast-growing, renewable softwood and hardwood species such as pine, poplar, and aspen from self-regenerating forests or plantation-grown trees. Murus’ OSB manufacturer is a member of the SFI (Sustainable Forestry Initiative). 800.626.8787.
Made with OSB sandwiching an EPS core, the Insulspan SIP System comes pre-cut and ready to install as walls, floors, and roofs. A 6?1/2-inch wall panel offers a nominal R-value of 21.1; a 101/4-inch roof panel provides a nominal R-value of 35.1. The company offers special-order SIPs using FSC-certified OSB.517.486.4844.
The company offers a full line of polyurethane-core SIPs with an emphasis on cement board–clad products for high-humidity areas. A wide array of cladding materials is available, including metal, plywood, and some finished wood products along with traditional OSB. Magnesium oxide is an option for the interior skin. 704.636.5131.
Filaments on Hydrofilament drainable housewrap create a 1-millimeter gap, providing pathways for trapped moisture to escape and helping exterior walls dry more quickly. According to the firm, the wrap’s performance characteristics do not diminish over time and after exposure to wet conditions. The weather-resistive barrier resists moisture and air infiltration, and its breathable structure allows interior moisture vapor to pass through. It comes in 100-foot rolls. 800.346.7655.
Enertite open-cell polyurethane water-blown spray-foam insulation offers an R-value of 3.5 per inch for use in walls, roofs, attics, and rim joists, and it also provides a sound barrier for use on interior walls. The one-step product expands to fill the wall cavity, including in and around difficult-to-reach areas such as pipes and wiring for a seamless barrier. 888.900.3626.
The Endurance S-250 wind turbine can be connected directly to the power grid without the need for an inverter. It has a power rating of 5 kWh and can match the energy requirements of average U.S. households that consume up to 18,000 kWh per year, the company says. A braking system and over-speed protection stop the rotors in cases of extreme high wind or fault conditions. 888.440.4451.
Consisting of solid one-piece pre-cut SIP units, the Insulspan Structural Insulated Panel System comes ready to assemble as wall, floor, or roof components, reducing construction time and improving efficiency, the company says. According to the firm, the system’s roof and wall assemblies offer a 40% to 60% reduction in heat loss and significantly reduce air leakage. 800.726.3510.
