Lessons Learned and Best Practices

DOW Thermax XArmor ( ci ) Exterior Insulation

COMPLIANCE to COMMITMENTClaims • Risk Management • Safety • Quality

PROJECT DESCRIPTION• 5‐Story Steel Framed Construction including Connector Bridge to Main Campus

• Primary Architect is Cannon Design with local Partner LWC Incorporated

• 120,000 Sq.Ft. ( Levels 2 and 3 are Shelled Space for Future Fit‐Out )

• $ 40,500,000

• DOW Thermax XArmor ( ci ) Exterior Insulation

• Brick and Cast Stone Veneers

• Composite Metal Panels

• Full Height Curtain Walls and Punched Openings

PROJECT RENDERING

PROJECT DESIGN HISTORY• Initial Exterior Envelope Design was 2 3/8” Spray Polyurethane Foam Insulation over 5/8” Exterior Sheathing

• Third Party Consultant Wiss, Janney, Elstner conducted a Peer Review based on this design

• Delay’s in receiving 100% Design Documents would have dictated trying to apply the SPF Insulation in January in Ohio which would have required fully tenting and heating the structure to meet the SPF Insulation temperature requirements

PROJECT DESIGN HISTORY• Architect(s) and Owner asked for alternatives to keep the project on schedule

• Exterior Sheathing Sub‐Contractor had experience with installing the DOW Thermax Systems and offered it as an Alternative

• Owner and Architect accepted the proposed Alternative to stay on schedule

• Wiss, Janney, Elstner conducted a “ Commentary Only “ review of DOW Thermax System

PRODUCT DESCRIPTION AND COMPOSITION• 4’ x 8’ x 12’ panels with ship lap configuration at top and bottom of panel

• Exterior face of panel: glass‐fiber reinforced polyisocyanurate foam core faced with a nominal 4 mil embossed thermoset‐coated aluminum. Exterior face serves as a drainage plane and a water‐resistive barrier

• Interior face of panel: 1.25 mil embossed aluminum

FASTENING PATTERN

FASTENER ACCESSORIES – DOW PANEL TO STUD

FAST BUILDING DRY‐IN POTENTIAL

MASONRY ACCESSORIES – BRICK TIES

LIQUID FLASHING MATERIAL• Elastomeric Spray that forms a tight, seamless

barrier**

• Surface and Ambient Temperatures should be 35F and rising and below 120F during application

• Applied at 50 mils +/‐ 5 mils

• Build up to 50 mils with two passes, one to fill the joint, the next to build the thickness and achieve proper joint coverage

• Joint coverage is 3” +/‐ 1”

• Coverage into rough openings is 3” onto the face and 3” into the opening

• Penetration coverage is 2” onto the face and 2” onto the penetration

** When applied correctly per Manufacturers Instructions

LESSONS LEARNED

PRODUCT DAMAGE IS TO BE EXPECTED

GAPS GREATER THAN ¼” WIDE MUST BE TREATED

GAPS AT STRAP BLOCKING FOR STONE

SEQUENCING OF GAP TREATMENT BEFORE SPRAYING• Encourage Installer to provide two

crews such that Gap Treatment can

stay ahead of Spraying Operations

• Drying Times of Gap Treatment need

to be factored into Scheduling of

Spraying

• Coordination of other Trades Work

being held up waiting on Gap

Treatment and Spraying

CLEAR COMMUNICATION TO NEW SITE WORKERS• Trade Worker who began initial

start of spraying on West Elevation was not at the Pre‐Installation Meeting

• 1st Work Inspection revealed that he did not understand extent of spraying detailing at vertical soffit to roof transition

• Corrective Action was implemented

• New Trade Worker to site repeated the same deficiency on South Elevation

STRUCTURAL LINTEL CONDITION SNAF‐OOO• Architectural Detail showed bolted

Lintel Connection with bolt head on exterior side of metal stud

• Transition from 2 ½” Thermax to narrower section without reducing drainage cavity

STRUCTURAL LINTEL CONDITION ADJUSTMENT

BEST PRACTICES

PROPER FLASHING OF PENETRATIONS

THOROUGH INSPECTION OF SPRAYED AREAS PRIORTO MOVING TO NEXT AREA
