Structural Insulated Panels - SIPS . Sustainable . Post Frame Construction . Cross Laminated Timber - CLT Sustainable Attributes Wood - A Model of Sustainability • Renewable & Bio based • Low Embodied Energy (Solar) • Absorbs CO2, Releases Oxygen .From 1953 to 1997 • Clean Production Process • Forest inventories grew 36% * • Thermally Superior • Biodegradable • Over 50 million wood-frame homes were built Source: ATHENA Sustainable Materials Institute www.athenasmi.ca * Source: U.S. Forest Service

Forest Facts Certification . 1/3 o f t he USA i s f orested or 750 m illion acres . Only 250 million acres are open to logging Wood is: . About 2 Billion trees planted annually .

WHAT ARE SIPS? Structural Insulated Panels

SIPs are composite, Combining the efficiency of high performance, panelization and accuracy of self-supporting, machine cut panels in creating 5 structural building building elements all at once: panels with an insulating core of rigid 1) Structural Assembly for both foam and structural gravity and lateral loads 2) Insulation facings or skins, most 3) Air Barrier and Vapor Retarder commonly of 7/16” 4) Wire chases included thick oriented strand 5) Flat, Nailable Surfaces for board (OSB). interior and exterior finishes 105

Panel Thickness R Values

. There are five nominal panel thicknesses.

. The core dimensions match dimens iona l 2x ’s:

. 3 ½”, 5 ½”

0 . 7 ¼”, 9 ¼”, 11 ¼” . R-Value reported at 75 F is an FTC requirement.

. As the temperature decreases the R-Value increases. SIPS = Strength SIPs and Commercial Applications

Design Advantages January 1995-Kobe, Japan •Integrated system 7.2 maggqnitude earthquake •Close tolerances Damage over $100 billion •Complex CNC cutting Six SIP homes Suffered NO •Large Spans structural damage

1998-Clermon t, Georg ia This SIP house survived a tornado with suppgerficial damage while 27 conventional houses around it were destroyed.

Alternative Post Foundations Cross-Laminated Timber .New generation of lightweight and ppyrefabricated systems

.Consists of wood stripp(ps (planks ) stacked crosswise on top of each other (glued or nailed)

.Thicknesses of the panels vary from 50 to 600 mm

Cross Laminated Timber (CLT) Benefits of CLT . Speed of Erection . Overall Performance . Seismic (no soft story) . Acoustic . Vibrations . Fire

Photos provided by FPInnovations Benefits of CLT

. Sustainable Benefits . Carbon footprint . Low embodied energy . Tight building envelope (high energy efficiency) . Little waste . Cost Competitive Advantages of CLT Panels Why CLT is Different than Glulam?!

. Factory produced with high precision CNC machines . Quick on-site assembly (One storey/week or less per avg. size floor plan)

- Min site Noise (equipment/personal) - Min site Waste (high level of Beam-like member prefabrication) Thick Orthotropic Plate - Ideal for dense urban in-fill projects - Health and safety benefits One of the most promising wood alternatives to concrete assemblies.

Advantages of CLT Panels

. X-lamination minimizes swelling and shrinkage in the board plane . Relatively high in-plane (seismic) & out-of-pp()lane (wind) stren gth and stiffness properties . Has two-way action capability similar to a concrete slab (alternative) . Good fire resistance – heavy timber construction (inherent fire resistance) Questions?
