True Roof and True Wall Panels by Yankee Barn Homes combine the highest performing attributes of traditional stick-built construction with that of Structural Insulated Panels (SIPs). Like a SIP, True Roof and True Wall Panels layer an exterior wood sheathing over a rigid foam core insulation. Unlike SIP’s, True Panels incorporate structural studs for enhanced strength, durability, and design flexibility.
True Roof and True Wall Panels
SIP’s, or Structural Insulated Panels, are manufactured composite panels used in the construction industry. They are a sandwiched panel with a core of polystyrene or polyurethane foam between two layers or OSB (Oriented Stand Board/ Particle Board), or drywall. Yankee Barn True Roof and True Wall Panels are a trademarked system based on efficiency and ease of construction. True Panels create less on-site job waste than SIPs because SIPs require cutting to fit and cutting for window, door, and skylight options.
Yankee Barn Homes TRUE WALL™ PANELS are built with pre-installed windows, eliminating waste created by the time-consuming on-site cutting of SIP panels necessary to install windows. Further, True Wall Panels are sturdily fastened to 2×6 studs with hardware, rather than simply gluing wood sheathing to rigid foam insulation as with SIP’s. Contractors remark the True Wall Panels are easy and fast to install, and make for a superior, energy efficient product. The basic True Wall Panel wall is six inches thick and has an R value of 26.0 including sheathing.
Yankee Barn Homes TRUE ROOF™ PANELS create a vented “cold roof” system, preventing snow melt from forming dangerous icicles in the winter and providing a buffer from the heat of the sun’s rays. True Roof Panels are the only roof panels of their kind that bear the International Code Council (ICC) approval. The roof panels begin with 2×10 or 2×12 conventional framing to meet building code standards. To maintain structural integrity, individual parts of the panel are fastened with nails rather than a chemical bond or adhesive used in SIP’s. We use a rigid foam insulation, which provides the highest attainable R-value per inch of thickness (R-55.3 -66.5). Each panel incorporates two crisscrossing layers of insulation to reduce thermal breaks and heat loss. A full-width roof vent space is built into the panel design to assure a cold roof deck, as required by most shingle manufacturer’s warranties. This air space helps to minimize ice dams and prolong shingle life.
