Title 24 & High Performance Enclosure Solutions:Structural Insulated Panel Systems (SIPS)
STRUCTURAL INSULATED PANEL ASSOCIATION (SIPA)

Today’s Topic: Builders & SIPS
Meet T24 Quickly: SIPS are the easiest and most cost effective way to meet Title 24
Benefits Beyond T24: • Shorter framing time/faster close in: 1/2 the time
vs. 2x6 framing (great for labor shortage)• Less skilled labor needed, fewer trades• Earlier move in/sales dates • Shorter financing terms to carry• Tighter structures reduce HVAC requirements
Builder Benefits … Title 24 & Beyond
Real Life: Builders & SIPS
1,150 sf Homes Each Installed in One Day4 men installed in 9 hours
7,000 sf19’ tall walls 7 men installed in 11 days
Fewer Steps + Less Skilled Labor = Install Savings

SIPS 101: The Basics• Turn key structural and insulated framing systems (roofs,
walls & floors)• Large panels (up to 20ft spans), replace exterior shell
framing components (Stick/Truss, CMU, ICF, Steel Studs, Tilt-up, etc.)
• Warranted & proven system (50 + years in the field)
• Factory engineered accuracy eliminates variations found in conventional lumber (straight, plumb walls)
• Large engineered panels shipped to the site ready to install
• Structurally stronger than 2”x6” construction SIPS replace sticks
• Local: Manufactured in California
• Meets or exceeds all required Building Codes

Energy Efficiency
SIPS Offer Extreme Efficiency
Air tightness = Efficiency.Continuous Insulated Panels address heat loss (air exchanges) and easily reduce a structure’s energy consumption by up to 58%.
2”x6” Stick Framed Construction
SIPS FramedConstruction
15 Times More Airtight
Title 24 Simplified With SIPS
Controlling air exchanges is critical to gaining energy efficiency. This is recognized within Title 24 and as such, SIPS are deemed to comply and are the only approved non-concrete building method:
SIPS are 1 of 4 Title 24 approved
assemblies offering minimal air leakage
California’s 2016 Building Energy Efficiency Standards
Beyond T24: Proven Efficiency & Code Approvals
SIPS are 58% more energy efficient than stick framed construction • More than 40 years of in-field testing show HERS
ratings well below IECC required air exchanges/leakage.
• The DOE (through Energy Star) has waived the requirement for blower door tests nationwide.
• Other Code Approvals*: ICC and NTA, LARR approved, Seismic Zones D,E & F approved….
* Not all SIP manufacturers have all approvals. California based Premier Building Systems (Only CA SIPS Manufacturer) does!
Beyond T24: DOE Endorsed
“I get it; SIPs is an entirely different enclosure paradigm and builders don’t like change.
As a result, builder cost calculations too often don’t recognize the significant savings from the benefits (of SIPS) … not to mention what should be much more satisfied homebuyers.
But I remain hopeful because there are builders that have made the commitment to get past the learning curve and internalize all of the benefits of SIPs.”
Sam Rashkin, Chief Architect, Dept. of Energy Building Technologies Office, wrote a detailed article for Builder Magazine advocating for SIPS for the building envelope.
Construction & Installation
SAVINGS
SIPS Simplify Construction in California
When 3 Work?
SIPS1. SIP = Exterior wall sheathing,
continuous cavity insulation, sheathing for siding attachment
2. Weather resistive barrier3. Siding
Why Use 7 Steps
STICK FRAMING1. Sick framed wall2. Exterior wall sheathing3. Insulate wall cavity4. Continuous insulation5. Sheathing or furring for
siding attachment6. Weather resistive barrier7. Siding
SIPS in Attics & Roofs
The same principles (reduced steps) that apply to walls, also apply to roofs:
• Up to 24’ spans• Large panels install fast• Superior unvented attics
• Cost savings for soffit and ridge vents • Fire-rated assembly difficult to achieve
with other unvented attic options• Proven structural capacities result in option
to eliminate trusses for cathedral ceilings
Specific Installation Advantages
• Faster Install (no studs to find) – less laborers • No special requirements for trades (lower cost subs)• Less time on the job for laborers (less insurance)• Pre-cut panels install with minimal laborers
(addresses current labor shortages!)• Ready to install, less mess & virtually no costly SIP
waste to send to the landfill• Factory cut edges for accuracy and square edges• Every screw grabs – no spinners• Large panels simply assembled, removing much of
the liability of other framing methods
Additional SIPS Advantages
Large strong panels with few seams, virtually eliminate settling issues common in stick framing (AKA - Callbacks!):
• Stucco Cracks• Window or Door Sticks• Nail Pops• Drywall hole repair• Exterior is less likely to get damaged,
sustains less damage & easier to repair• Interior of exterior walls are fully sheathed• No drywall holes, only scrapes• Easy to repair drywall damage
Trade Advantages
Openings and wall lengths are accurate (factory controlled manufacturing)
Offers advantages for subs throughout the project construction process…
• Windows line up from floor to floor• Doors and windows are installed faster• Cabinets and counter tops plumb• Flooring always fits• Millwork installs quickly, no bowed walls
What about Electrical?
Built in chases• Horizontal at outlet and switch levels• Vertical about every 4’-0” or as
requested
Easy to push/pull cable (fish tape)• Can use Romex
Large school in Las Vegas, saved $1M in electrical install
• Consistency in install• Simply pulling wires through chases
SIPS & HVAC Systems
• Reduce mechanical systems • Can use 3-4 ton AC unit rather
than 5-6 ton … or simplify with multiple mini-split units
• Smaller HVAC systems offer significant cost savings
• Smaller & more efficient ventilation systems can be used
Tighter more efficient structures = Smaller HVAC
~ $752~ $1552
~ $863
Warranted Advantages
• Chances are, when comparing warranties to conventional or advanced framing, you won’t find much.
• With Premier SIPS, we offer a limited 20-year warranty* for a building owner’s peace of mind.
50 Years of SIPS Advantages
We know change isn’t ideal. In this case SIPS framing & enclosures offer change for the better. To recap… • SIPS install fast, require minimal trained framing
labor and reduce installation/sub costs• Contractors and Developers have converted and
won’t look back• Building Science experts recommend SIPS• The SIPA (Structural Insulated Panel
Association) has decades of project data available to demonstrate all of these advantages
• Title 24 automatically accepts SIPS – create enclosures in one step instead of seven!!
