Learning ObjectivesLearning Objectives

1. Introduce New Energy Code and Design Standards for continuous insulation (ci) and air barriers requirements for exterior framed wall assemblies.

2. Deconstruct “perceived” value of traditional cavity insulation methods and Reconstruct new strategies for higher “effective” value of exterior continuous insulation opportunities.

3. Outline the challenges in framed wall design and detailing associated with the integration of continuous insulation (ci) behind traditional veneer cladding.

4. Understand the interrelationship between continuous insulation (ci) and improved energy efficiency, reduced energy consumption and overall improved building envelope performance.

Continuous Insulation

CI moves ‘traditional’ claddings off the wall

• Cantilevered further off the structural line

• Increases “moment” stresses at points of anchoring and bearing

Definition of CI• Insulation that is continuous across

all structural members without thermal bridges other than fasteners and service openings. It is installed on the interior, exterior or is integral to any opaque surface of the building envelope

Coordinating CI• Change in condensation

potential?– Must conduct WVT analysis

• Is ‘CI’ compatible with air / water-resistive barrier?

– Asphalt will eat foam plastic

• How will ‘CI’ be installed?– Adhesive, fasteners, etc.– Does this affect code performance?

• Who is responsible for coordinating these items?

– The general contractor?– The sub-contractors?

• Anchors & Ties• Bearing Angles, Lintels and

Cost is substantially increased



Bearing angle reconfigured to meet definition of CI

Cost is additionally increased

Stucco & Siding Stucco & Siding

CI is ‘non-structural’• Cannot support the weight of stucco• 8 – 12 lbs. / s.f.Excessive ‘moment stress’ on

extended fasteners is createdRequired drainage plane? • Face of open jointed CI or backside of

cantilevering conventional stucco off the face of wall

Typical Detailing - Jamb

Wall components are sized, designed and detailed to fit traditional wall conditions

• Windows, doors, louver frames, electrical boxes, etc.

• Solid structural attachments can be made

• Proper “seal” can be accommodated between cladding and wall component– Sealant and baker rod



Conditions Change Drastically

• Traditional wall components no longer “fit” the conditions

• Proper “seal” cannot be accommodated– Veneer cavity is left open– Sealant cannot bond to CI


Non-Typical Detailing


• In most cases, veneer / cladding must “return” back to the face of wall– Close cavity– Accommodate proper ‘seal’

• Does this meet the definition of CI? – NO

• Does this add cost? - YES


Detailing Options?• Incorporate frame extension• Does this meet the definition

of CI? – YES• Fire safeing maybe requires

around penetration• Does this detail condition

add cost? - YES

• Does this meet the definition of CI? – Maybe

• Does this add cost? - YES


• Adding Continuous Insulation behind Traditional Claddings– Potential Positives

• Adds R-value• Mitigates Thermal Bridge at Framing• Substantially improves Energy Efficiency• Minimal cost increase for maximum benefit

– Potential Negatives• Cantilevers the weight of traditional claddings of structural line

– Increases attachment / bearing steel cost• Widens Footings / Bearing Walls

– Increases foundation cost• Alters traditional wall penetration / cladding return detailing

– Increases installation cost– Have the specific assembly components been tested to NFPA 285?

• Likely Not – Increased cost and time

Original Costs: 37,000 sf of Wall– Brick & Limestone – original design

• $ 25.99/sq.ft. = $ 961,594.00 – 4” EIFS with Drainage w/ Specialty Brick Finish – value engineered

• $ 13.54/sq.ft. = $ 501,000.00– Cladding Savings = $ 460,594.00

Associated Costs:– 17.57 fewer cubic yards of concrete:

• $ 6,149.50– 13.45 fewer tons of structural steel:

• $ 44,385.00– Additional Savings = $ 50,534.50

• Total Direct Savings = $ 511,128.50 – $ 13.81 / sf
