Structural Insulated Panels … What Are They?

The anatomy of a Premier SIP…

A composite of three materials:

OSB(Oriented Strand Board)

InsulFoam EPS(Expanded Polystyrene)

Laminating Adhesive

SIPS Features & Benefits

Building envelopes15X tighter than conventional framing (Oak Ridge Nat’l Labs)

Prefabricated panels (up to 8’X24’) Faster Framing = Faster Completion (Installed in days not

weeks) Reduced framing labor (30-50%) Reduced jobsite waste/dump fees

Reduced operating costs – up to 60% savings on heating and cooling (ORNL)

Stronger – Greater loads than standard stick framing Straighter – Engineered predictable product Greener – Energy savings, environmentally

responsible LEED NC (up to 30 pts) 99% recyclable Energy efficient product qualifies for tax credits & incentives

The Science Behind Saving with Premier SIPS

8’X24’ panels: Fewer gaps and seams reduce air infiltration

Reduction in studs dramatically reduces thermal bridging

Solid EPS core eliminates air movement in walls/roofs (convective looping)

Reduced air movement = superior whole wall efficiency over 2x6 R19 construction

SIPS in Commercial Applications Wood based construction Used for the total envelope

or just roofs or just walls

Commercial applications National Chain Restaurants Multi-Family, Senior Living, Lodging Strip Malls Government (Post Offices, Schools, etc.) Churches & Non-Profit

“SIPS are so significant to airtight construction that Energy Star has waived the requirement for blower door tests for SIPS construction across the U.S.” - U.S. EPA

Restaurants & Dining

Lodging & Churches

Government & Education

Strip Malls, Grocery & Retail

When do you use SIPs?

If your client wants energy efficiency use Premier SIPs for framing the envelope

Many studies are available to substantiate the energy efficiency of SIPs building envelopes

10

When do you use SIPs?

If your Contractor needs labor savings use Premier SIPs for framing the envelope

SIPs can save up to 55% on labor

11

When do you use SIPs?

If the project timeline would benefit from a shortened rough-in time use Premier SIPs for framing the envelope

12

When do you use SIPs?

13

Where do you use SIPs?

Typically, the exterior envelope is where Premier SIPs are used:

- Insulated floors- Exterior Walls- Roofs

14

Panel Sizes

Premier SIPs panels can be manufactured in sizes from

2’x8’ Up to 8’x24’

15

Panel Thicknesses / R-Value

There are five nominal panel thicknesses

The core dimensions match dimensional 2x’s:

• 3 ½”, 5 ½”• 7 ¼”, 9 ¼”, 11 ¼”

16

Panel Thicknesses / R-Value

The 3 ½” and 5 ½” panels are typically used for walls

The 7 ¼”, 9 ¼” & 11 ¼” panels are typically used for floors and roofs

17

Splines - Panel ConnectorsPremier SIPs has three basic types of splines or panel connectors Listed in order of cost

effectiveness they are:1. The block or surface

spline (Type S panel)2. The I-Joist spline (Type I

Panel)3. The lumber spline (Type

L Panel)

18

Splines - Panel Connectors

The block or surface spline (Type S Panel)

Either a 3” wide piece of OSB

or A 3” wide mini panel This spline type does

not increase the panels span capability

Used with all width panels

19

Splines - Panel Connectors

The I-Joist spline(Type I Panel)

Less thermal bridging than with solid lumber splines

Adds strength to the panels

Maximum spacing of 4’ oc

This spline limits the maximum width of panel to 4’

20

Splines - Panel Connectors

The lumber spline (Type L Panel)

Double 2x’s or solid 3” min. width lumber

LVL may be used Maximum spacing is

4’ oc Adds strength to the

panels both axially and transverse

21

Wall Panels Most walls are 5 ½”

core panels because of minimum R-19 insulation requirements

Wall panel heights and widths are customized for each project

Both skins of the wall panel must be in bearing at the bottom of the panel

22

Wall Panel Details

The top and bottom of the wall panel will have 2x plating

The top of the wall may have a cap plate for additional bearing capacity

Wall panels will have 2x plating at the corners or changes in direction along with long screw fasteners

23

Wall Panel Details Wall panels will

have 1.5” diameter electrical chases

Horizontally Vertically

Top and bottom plates are drilled during installation to access the vertical electrical chases

24

Roof Panels

Most roofs are 9 ¼ ” core panels because of minimum R-38 insulation requirements

No Attic - Vaulted ceilings are common

Minimum 1 ½ ” req’d for bearing of bottom skin

25

Roof Panel Details

Common overhang details:

Square cut roof panel

Plumb cut roof panel

Ladder framing Reduced

overhang details

26

Air Tightness

Premier SIPs create a very tight envelope.

• Mastic at joints• 0.05 ACH for SIPs• 1 ACH for tight stick

• ACH = air changes per hour

Require mechanical air exchange system

Be careful with fire places and kitchen fans

• Depressurize the building

27

Air Tightness

Premier SIP Tape intended to address model code requirement for a vapor retarder Applied at panel

joints Premier SIPs

Documents that provide guidance:

Technical Bulletins #28 and #32

Premier SIPs Detail PBS-013

28

Thermal Barriers

The major model codes require thermal plastics to be covered with an approved thermal barrier:

• ½” Gypsum• Or an approved

material This requirement

applies to Premier SIPs

29

Hourly Assemblies

Premier SIPs has multiple hourly rated fire assemblies

UL P517 UL P822 UL P839 UL U524 Type L Wall Panel - E119

assembly tested by Omega Point Labs
