Benefits to Builder and Buyer for OSB
SIPs
Lower Insurance and Financing Costs: By using
SIP's for the roof and walls, the shell of a home can be erected in a single
day; additionally, the insulation is already in place. The reduction in time
under construction results in lower insurance and financing related
expenses.
Enhanced Site Security: A secure building
envelope is achieved in one day, drastically reducing the risk of losses due to
theft.
Greater Building Capacity per Crew: The on-site
labor savings related to erecting the home shell enables your work force to
build more homes in a given period of time.
Improved Design Flexibility: Panels provide
high vertical and horizontal load-bearing capacity, providing a wider range of
economical design alternatives; the superior thermal performance of a SIP’s
shell further broadens design choices, making features such as cathedral
ceilings much more practical.
Shorter and Cheaper HVAC Runs: The air duct
system runs can be considerably shorter. The traditional practice of running
duct work to the exterior wall of each room was intended to counter the
infiltration of air through perimeter leaks in conventionally built walls. The
air tight nature of a SIP home enables duct runs to terminate at the closest
wall of each room to the central run, providing considerable savings. Houses
designed to optimize savings from SIP construction usually use a central utility
pod design that further minimizes utility runs of all kinds.
Smaller, Less Expensive HVAC System: A SIP’s
home tends to be 50% to 70% more energy efficient than a comparably designed,
conventionally built home. To ensure proper operating frequencies, the heating
and air conditioning systems for a SIP’s home should be significantly smaller
(and thus less expensive). Tonnage for a SIP home AC system is typically 50%
less than in a comparable stud framed home.
Cheaper Drywall and Cabinet Installation: There
are no studs to find in SIP built walls; directly behind the interior drywall is
a solid layer of OSB. Drywall does not have to be trimmed to terminate at a
structural member; drywall, trim and cabinet installation times are therefore
significantly reduced. Additionally, punch list items related to popped drywall
nails and screws are virtually eliminated and walls are absolutely straight and
flat.
Reduced Construction Waste Management Costs:
Custom built SIP’s eliminate a great deal of construction waste, significantly
reducing waste management costs, including dumpster charges and landfill
fees.
Faster Electrical Installations: Pre-cut wire
chases in SIP’s eliminate the need to drill studs for electrical
wiring.
Straighter, Truer Walls: SIP’s eliminate the
problems and expense associated with warped wood studs. SIP homes require no
external wall bracing thus saving significant lumber and time in wall truing and
bracing.
Safer Job Site: By greatly reducing on-site
man-hours required to build a home as well as reducing the need to handle
construction waste, the risk of on-site injury is significantly
reduced.
Substantial Completion of Federal Tax Credit
Eligibility Criteria: Thanks to the thermal properties of SIP built
home, SIP home builders can readily qualify for energy-efficiency-related
Federal tax credits. Provisions in the Federal Energy Policy Act of 2005 allow
home builders to claim a tax credit of $2000 for qualifying energy-efficient
homes completed after December of 2005. The qualification criterion is based
upon the estimated heating and cooling energy consumption of the home; energy
usage must be at least 50% below the heating and cooling consumption of a
comparable home built to the standards of the 2004 supplement to the 2003
International Energy Conservation Code (IECC). To claim the tax credit, a
builder must have the home’s energy performance estimated and certified by an
independent certifier that is accredited by the Residential Energy Service
Network (RESNET).
Year Round Building: SIP’s are built in a
controlled environment and can be erected in a day; provided foundations are
ready, efficient construction can continue year round without regard to
weather.
Stronger Structure: Stud framing supports
vertical loads intermittently at the stud locations and relies on the integrity
of a multitude of connection points between the studs and the sheathing to
provide shear strength. With SIP built walls, loads are distributed evenly
across the entire panel assembly-- much like an I-beam-- providing greater load
bearing capacity. According to Building Systems Magazine, a SIP built home is
three times stronger than a conventionally constructed
home.
