How did SIP construction help you get this job?
Due to the owner's strong desire for exceptional building energy performance compared to traditional manufactured steel buildings, the decision was made early in the planning stages to utilize SIPs for the walls and roof of the hangar.
With our 18+ years of experience engineering with SIPs, the owner was confident that we could design his vision even though it was uncommon to use SIPs for this size of aircraft hangar. Our familiarity with SIP manufacturing also afforded us the opportunity to maximize efficiency with the use of SIPs in the project.

SIP wall thickness and core material: 8 1/4 - 10,800 sq.ft.
SIP roof thickness and core material: 12 1/4 - 10,860 sq.ft.
Describe the benefits of using SIPs on this project. Did SIPs help save time, labor, construction costs, or energy?
Using SIPs allowed for expedited erection of the structure, resulting in lower labor costs. The resulting building is very energy efficient due to the high R-values and minimal thermal-bridging of the SIP roof and walls, providing a better value compared to that of a manufactured steel building. Utilizing SIPs in combination with timber framing allowed us to maximize the embodied carbon in the structure, minimizing the use of steel, a high-carbon footprint material. Moreover, utilizing the interior SIP skin as a painted surface saved materials, adding to the sustainability and rapid construction.
Hangars are naturally devoid of a large quantity of windows and doors, so utilizing a product that serves more than one purpose (i.e. forms the shell and braces the building) provides greater efficiency of building materials compared to a manufactured steel building.

Describe any innovative design elements or structural engineering involved:
The higher power hydraulic door system was a marvel in itself. The hangar door assembly is entirely self supporting and does not rely on the structure of the building. The hangar door has a 3" SIP nail base plated to the inside of it.
The Flying H hangar roof structure combines SIP roof panels with steel open-web joists to create a 100ft clear-span in two directions, designed to support a roof snow load of 30Lbs/sf. The 30ft tall walls, with no intermediate floors to provide bracing, consist of SIP panels fastened to the outside face of 8-3/4in wide glued laminated timber columns ranging in depth from 9in to 16-1/2in (chosen

Describe the HVAC system used on the project:
In-slab radiant heat is provided, utilizing a high-efficiency natural gas-powered boiler.
