One hour fire rated systems can be activated using high performance thermal barriers such as type X and C gypsum board. Buildings with sprinkler systems may not require a thermal barrier. Consult applicable codes regarding compliance requirements. Mechanical Ventilation Properly installed PACEMAKER SIPs greatly reduce air movement through walls and roofs. While fewer air exchanges save energy, air quality is affected and humidity is increased possibly causing mold and mildew problems. A professional, familiar with tight construction such as SIPs, should design and install a HVAC system that includes an adequate fresh air ventilation feature. Vapor Retarders We recommend the use of vapor retarders when mandated by code or required by climate conditions. Sealants applied to all connections (foam to foam, foam to wood, and wood to wood) are required. In addition, a 6 mil polyethylene vapor retarder must be installed at all roof panel connections including the ridge. Weather Resistive Barriers Proper usage of sealant at panel connections is necessary. Flashing and sealants around all rough openings and penetrations is required. Properly installed housewrap will help protect the exterior OSB skin from damage due to moisture intrusion. Storage, Handling and Protection PACEMAKER SIPs must be stored in a level, well supported manner, fully covered with tarps or other protective wraps. When installing panels with a crane, straps or an I-bolt should be used. Under no circumstances should panels be lifted by a single OSB facer. Roof panels must have a temporary water resistant paper applied after installation. PACEMAKER Engineered SIPs utilize exposure I rated OSB skins which withstand limited weathering. The weatherproof exterior cladding system must be installed promptly. While the SIPs are treated to resist termite and carpenter ant intrusion, standard deterrents such as insect clips, flashing or traps should be installed.

COMMON ERRORS COMMON ERRORS PACEMAKER SIPs Do s and Don ts 1.) Do handle SIPs with care. Do not hoist by single skin or drop on corners. 2.) Do provide adequate support for SIPs when storing them. Store SIPs laying flat and covered to prevent exposure to moisture. Unsupported skin OSB Skins directly on concrete 3.) Do provide 1-1/2 diameter access holes in plating to align with electrical wire chases in SIPs. 4.) Do hold bottom plate back from edge of floor system 7/16 to allow full bearing of SIP OSB skins. 5.) Do use on all wood-to-wood, wood-to-eps, and EPS-to-EPS connections. 6.) Do provide level and square foundations or floors that support SIP walls. 7.) Do provide adequate bracing of panels during erection. Non Continuous lumber 8.) Do remove debris from plate area prior to panel placement. 2nd Top Plate does not span both osb skins. Unsupported horizontal joint 9.) Don t put plumbing in PACEMAKER SIPs, furr out interior section for pipes if necessary. 10.) Don t cut the skins for electrical chases, use factory provided chases in SIP core. 11.) Don t install SIPs directly on concrete. 12.) Don t put recessed lighting in panels.
