FREQUENTLY ASKED QUESTIONS
What are Structural Insulated Panels or SIPS? SIPS are component-building panels (sometimes referred to as sandwich panels or stress skin panels) containing a structural foam (insulating) core bonded between two structural skins. At Enercept we use expanded polystyrene (EPS) foam for the insulating core and typically use oriented strand-board (OSB) for the exterior and interior skins.
How does the cost of a SIP structure compare to a stick-built? When you factor in material cost, labor expense and job site waste with the benefit of a lifetime of energy savings, The Enercept System is a lower cost building solution.
Do Enercept Panels contain Formaldehyde or CFC’s? No. Enercept SIPS were tested at the University of South Dakota; no traces of formaldehyde were detected. Nor do the panels product off gassing of dangerous chemicals.
What is the R-Value of Enercept SIPS? First, realize there are 3 methods of heat transfer: convection, conduction and radiation. R-Value is the measure of resistance to heat loss by conduction only. The most import factor in thermal efficiency is the continuity of the insulation. The Enercept SIP system results in a solid envelope of insulation where even the connections posts have a foam core. Therefore, Enercept SIPS have the ability to resist heat transfer by both conduction and convection (air movement). With this in mind, is is reasonable to assume that a conventional home would require a R-40 wall to compare with a 6-inch Enercept wall (R-24).
How do you ventilate an Enercept SIP Roof? Ventilation in a SIP Roof is not necessary in most climates. Model codes allow both vented (cold roof) and nonvented (hot roof) roof assemblies. Because SIPS are insulated conductive loss of heat is avoided, negating the problems usually associated with a nonvented roof. If you must ventilate your roof, 2x strips can be attached to top of the roof and then covered with sheathing to form a vented layer over the SIP panels.
How do you wire an Enercept Structure? Enercept was the first SIP manufacturer to patent factory-installed electrical chases. All Chases are marked on the interior sheathing of the panels for easy identification. Our SIP roof panels are prewired in the factory per your specifications. Simply drill access holes through the sill and top plates to access electrical chases. A comprehensive electrical guide is available.
Do Enercept Homes have moisture problems? Enercept structures are very air tight compared to other building methods. Generally a moisture barrier is applied to the exterior of the structure. Seam tape is provided for all interior panel connections and an air exchanger is strongly encouraged. These measure will not only protect your home from moisture but it will also create exceptional indoor air quality.
Is the Enercept SIP System code approved and warranted? The Enercept Building System has been accepted for use by HUD and is ICC/ICBO approved (ESR-1780). Enercept SIPs have been tested by RADCO, an independent third party testing agency, for strength and performance. Enercept offers a limited lifetime warranty against panel delaminating.
