tructural insulating panels While most architects and engineers are versed in the concept of SIPs (generically called "foam core panels" or "stress sf<in panels" ), many homeowners and builders are still unfamiliar with this revolu tionary product. Here are some fundamentals you should know:

The first SIPs were manufac tured in 1952 by the Dow brothers and were used in the construction of a residence built on the University of Wisconsin campus . When the project was completed, it was dedicated by Eleanor Roosevelt and is still in use today and in good condition. Due to the panel system's phenomenal energy savings and faster close-in times, it gained popularity as enclosures for timber frames during the 70s and 80s . In the early 90s the SIP market emerged and was led by a few manufacturers such as Murus, who tested their product to substantiate strength , fire resistance and durability. Today, SIPs are used in thousands of projects each year throughout North America and the world .

The strength of SIPs is intrin sic, and is based on the same principles as structural shapes such as I-beams. and stress-skin components such as an airplane wing . All th ree (SIPs, I-beams and airplane wings) share the same concepts. The outer skins or "chords" (in the case of an I-beam) are held apart and rigid by a center core or web. When these components are stressed by bending, the core is stressed in shear and the skins are stressed in compression or tension. Due to the distance of the skins (or chords) from each other, their strength-produc ing properties are increased exponentially.

SIPs consist of a rigid foam insulation core that is bonded between two layers of rigid sheathing, referred to as " skins." Murus SIPs are manufactured with rated skins and are capable of supporting axial and trans verse loads. Oriented strand board (OSB) is the most widely used skin material for structural applications due to its competitive cost, avail ability of sizes, and volume produced. ass is produced from fast growing, renew able trees which reduces the strain on our nation 's forests.

• Our limited lifetime warranty backs Murus polyurethane SIPs against delamination between the foam core and skins. This protects every one and provides security in knowing you have the best SIPs available.

OSB skins used by Murus are made of wood strands from fast-growth trees, one of nature 's most renewable resources. And our poly urethane foam is produced from petroleum by-products and recycled materials. Murus foam is 100% organic, does not contain formaldehyde, CFCs or HCFCs. If every home in the u.s. were built using Murus SIPs, it would save the eqUivalent of apprOXimately 1 billion barrels of crude oil consumed and burned each year.

Common insulating materials used in wall, roof, and floor construction fall into two general categories: fibrous materials (such as fiberglass and cellulose insulations), and foam plastics (thermo-plastics and thermo-set plastics). Polyurethane foam was selected as the core material for Murus SIPs only after studying research data on the properties and values of foam plastics. The Murus rigid polyurethane foam system is a highly advanced "state-of-the-art" thermo-set plastic formulation . While other foams in the same family are often referred to as "urethane," they are in fact merely chemical cousins to Murus polyurethane. Our system is specially designed for use in our exclu sive manufacturing process to achieve high performance in three areas (R-value, structural properties and fire resistance) that are critical to producing high-quality SIPs. Our polyurethane foam core and our composite panels have been tested by independent laboratories for structural capability, fire petjormance, and durability. We are enrolled in a voluntary third party quality control insurance program through which our manufacturing facility is routinely yet randomly inspected to verify consistent product quality. Our foam system is listed with a Class I fire rating. It will not draw back or melt like thermo-plastiCs such as expanded polystyrene (EPS) . When exposed to flame the

The properties and characteristics of Murus polyurethane are superior to that of isocyanurate and polyisocyanurate foams typically produced by the lamination method. The proprietary Nlurus manufacturing method-Uniform Dispersion Molding (UDM)-is a key component to creating our SIPs' superior characteristics. The UDM method enhances the properties of the foam and creates the strongest possible bond between the skins. The liqUid foam is uniformly dispersed throughout the mold; the foam expands, bonds and cures under 12- J 4 pSi, unmatched by any other method. UDM produces uniform foam density throughout the panel with spherical cells that give the foam superior and uniform strength. as compared to elongated "rice shaped" cells produced by polyisocyanurate lamination foams.

Independent studies show that air infiltration can account for up to 40% of the heat loss in a building. The airtightness of a build ing becomes even more important when consider ing overall energy efficiency. Air infiltration creates drafts and air stratification (cold floors and hot ceilings). These conditions rob energy and create a phYSically uncom fortable living environment. The Murus SIP system is 3 to 5 times tighte r than typical construction methods, saving energy and creating a controlled, comfortable interior living environment.

Independent studies demon strate that wood and/or steel framing members reduce thermal performance of the "whole-wall" R-value by 20% to 50% over R-values of insulating mate rials measured "in-the-wall." The Iv]urus SIP system outperforms other systems and methods because it does not reqUire conductive steel or wood framing, nor does it reqUire panel-to-panel spline connections.

Also known as "perm rate," water vapor permeability is the ability of water vapor to pass through a material. Methods or systems utiliz ing insulating materials with high perm rates allow wanted interior moisture to escape under heating conditions (winter) and allow unwanted moisture to enter under cooling conditions (summer). Conventional methods use a vapor barrier to reduce permeability. This method is

prone to condensation of vapor into water, which affects insu lation values. durability. and may promote mold growth.

Independent studies reveal a mere I % moisture content in fibe rglass insulation reduces its effective R-value by 50%. The polyurethane foam core in Murus SIPs does not absorb moisture; therefore. R- values are not reduced due to moisture.

Murus SIPs have the highest R-value per inch of any build ing system available. You can use a thinner wall section, which reduces the cost of window and door extension jambs. plates and nailers. and nets more floor space.

Installation of an a ir exchange system helps assure a comfortable and healthy living environment.

lfa From the highly advanced foam core to the highest quality interior and exterior skin materials, Murus chooses only the best. The finished SIP is molded to perfection with our patented cam-locks il1 place and our standard electrical chase located for convenient wiring. Whatever type of skins you choose you will be insured of receilting the very best SIP available. Several different
