Batt insulation can also slump down over time, leaving parts of the wall uninsulated. That’s because convection causes air to circulate between hot and cold surfaces within the wall cavity. As the temperature differential increases-that’s the difference between outside and inside temperature-the R-value of fiberglass decreases. Walls made with EZ SIPS cost $3.50 USD to $4.50 USD per square foot IN TOTAL! For the entire wall! That’s studs, plates, OSB and EZ SIPS panels!įiberglass is the least expensive insulating option. EZ SIPS leave the inner wall open, with removable, replaceable surface channels for wiring and plumbing. EZ SIPS’ rating of R-28 at 75F (24C) increases to R-33 at 9F (-13C).ĮZ SIPS are EZ to install, don’t out-gas, prevent convection, and when you foam the seam between panels with a can of sprayfoam they form a virtually airtight building envelope. Because of this, EZ SIPS’ R-VALUE CLIMBS as the temperature differential increases. It doesn’t permit air or moisture transfer. EPS is a rigid, durable, non-toxic closed-cell foam. If the floor deckis slightly off level, panels will not line up properly with each other, requiring cement grinding or messy on-site panel modification.ĮZ SIPS are rigid 6¾” x 4’ x wall height foam panels made from precisely routered expanded polystyrene EPS insulation™. Also as long as your foundation is perfectly square and level. And because you need to fur out the walls and / or build plumbing chases, you’re into more work and more material.Īside from the hassle of fishing wires (and cutting holes), conventional SIPS are great as long as you don’t mind paying extra for your walls, for engineering costs, for crane rental and often for long-distance shipping. They are tough for sub-trades to deal with, as they must fish wires through chases buried deep in the foam and cut holes in the OSB. Factory SIPS systems typically cost between $7.00 USD and $9.00 USD per square foot of wall. They are then stood with the help of a crane, and joined together. Entire walls are pre-fabricated, with openings cut out, and trucked to the job site. Here’s how EZ SIPS stack up against the competition:Ĭonventional structural insulated panels (SIPS) are a sandwich of oriented strand board (OSB) and foam. ![]() With EZ SIPS you get SUPERIOR THERMAL PROTECTION without changing the way you frame! SmartHomze does not provide for construction, interior partitions, finishes, appliances, cabinets, or plumbing fixtures.įour sizes of SmartHomez studio models are also available, ranging between 96 and 160 square feet, that are designed for use as home offices, art studios, pool houses, guest accommodations, emergency shelters, or field offices with optional solar PV panels.DARE to compare… Insulated Panels and EZ SIPS are revolutionizing the way homes are built!Įvery builder has a way they like to build. Kits for net-zero SmartHomze include the materials for the exterior walls (including vinyl or fiber-cement siding, standing-seam metal roofing, triple-glazed R-5+ windows, doors, flooring, HVAC equipment, photovoltaic system, and a heat-recovery ventilator. SmartHomze 1700 – The Sharon – 28’x32’ (1700 square feet) three bedrooms, 2-1/2 bathrooms, with wraparound porch SmartHomze 1200 – The Mason – 28’x32’ (1200 square feet) three bedrooms, two bathrooms, with wraparound porch SmartHomze 900 – The Woodstock – 20’x28’ (900 square feet) three bedrooms, one bathroom, with wraparound porch ![]() SmartHomze 750 – The Bedford – 20’x28’ (750 square feet) one bedroom, one bathroom, with wraparound porch and sleeping or office loft SmartHomze 560 – The Dover – 20’x28’ (560 square feet) one bedroom, one bathroom, with wraparound porch and storage loft While SmartHomze are designed for installation on a pier, they can also be constructed on a slab or conventional foundation and are initially available in five sizes ![]() The SIP panels can provide homeowners with an additional 72 points for LEED or 242 points for the National Green Building Standard. Oriented Strand Boards (OSBs) are harvested from sustainably managed forests. One of the key energy-saving components of SmartHomze are the urethane foam panels that have a R-6.8 per inch R-Value, the highest of any insulation currently available. With an estimated $150 per square foot cost of construction (not including permits, site work, or foundation), SmartHomze are significantly more affordable than typical green homes that range between $200 and $250 per square foot and more in line with construction costs for an average new home that doesn’t include sustainability features. Vermont-based Vantem Panels, one of the United States’ first producers of SIPs (structural insulated panels) and one of three American producers of urethane panels, has released the first affordable net-zero energy kit homes: SmartHomze.
