A framing assembly has at least one rafter vent assembly having a connecting member with a plurality of vent tubes for providing supplemental ventilation and additional structural support to a frame of a building structure. The at least one rafter vent assembly may be an interior rafter vent assembly or an exterior rafter vent assembly. The interior rafter vent assembly has at least one brace member and a connecting member, with the connecting member having a connecting plate, two end plates, and the plurality of vent tubes. The exterior rafter vent assembly has the connecting member that has a connecting plate and the plurality of vent tubes. The framing assembly also preferably has a plurality of modified structural insulated panels (SIPs) and modified rafter splines.

A roof system includes a roof deck and a plurality of roof rafters supporting the roof deck. A thermal break is located between the deck and a first rafter of the plurality of rafters. The thermal break includes a break inner member contacting a first rafter exterior surface of the first rafter and a break outer member contacting a deck inner surface of the roof deck. The break inner member and the break outer member bound a thermal air break therebetween.

Agricultural barns, warehouses, and methods for construction including a floor, walls that include foam wall panels, a wainscot of impact resistant panels at a lower portion of the wall, and a ceiling formed from foam roof panels integrated into the roof truss assembly. Once the floor, walls, and ceiling are assembled, walls and ceiling can be coated over with an abrasion resistant, impact resistant polymeric coating (e.g., akin to a truck-bed liner), tying these structures together in a seamless shell that provides sufficient elasticity to accommodate typical expansion/contraction due to daily and seasonal heating/cooling, humidity changes, etc. The sealed interior envelope allows the interior surfaces to easily be pressure washed daily, or whenever else needed. Such construction is particularly well suited to an agricultural barn or warehouse, where cattle or forklifts may run into the lower portion of the walls, and pressure washing may be a daily need.

A purlin mounting system for use in a flat roof structure includes a purlin with a flat mounting wall and an upright wall extending perpendicularly from the mounting wall. First and second mounting shelves are attached to the upright wall and extend outwardly in opposite directions. Each mounting wall is positioned to receive an edge of a roof section thereon. The flat mounting wall and the upright wall define a vertical mounting channel extending from a lower surface of the flat mounting wall a distance less than the distance of the first and second mounting shelves from the mounting wall. A purlin positioning and mounting device is designed to be attached to a roof beam and includes a vertically extending support wall designed to extend upwardly from a supporting roof beam when attached to the supporting roof beam and to nest within the mounting channel.

A roof system is secured to a roof deck on a building. The roof system has a thermal energy absorbing product including a desiccant located between the roof deck and a roof barrier. The desiccant reversibly absorbs moisture, and in response thereto, heat is released and absorbed by the desiccant to effect a thermal management of the roof system.

Panelized wall and roof structures for constructing energy efficient buildings. The panelized structures have a structural layer with insulation, an airtight layer providing a primary air barrier and a vapor retarder exterior to the structural layer, a vapor open blanket layer including insulation and attached to the structural layer via structural screws, a weather resistant barrier provided exterior to the blanket layer and including an airtight, water-repelling, vapor-open fabric, and a rain screen provided exterior to the weather resistant barrier and including a drainage plane for channeling moisture away from the weather resistant barrier.
