Course Description

This course emphasizes the importance of detailing continuity in maintaining the integrity of the four control layers of the building enclosure. We will explore methods for identifying areas where continuity can be disrupted and solutions for maintaining control layer continuity in these areas.

5

Course Objectives

• Explain the four primary, code based control layers that make up a building enclosure system

• Define the primary issues related to continuity of building enclosure control layers in wood‐framed wall and roof assemblies.

• Review the common choices for products and materials for building enclosure control layers, including critical transitional areas.

• Compare different drawing details and solutions for their use in wood‐framed wall and roof assemblies.

Introduction

• Building Enclosures

– Provide proper separation between the building interior and the exterior to control:

– Water penetration

– Air flow

– Vapor transfer

– Thermal transmission

Weather Resistant Control Layer

2015 International Building Code (IBC) and

International Residential Code (IRC) require:

• Weather Protection

– Exterior walls shall provide the building with a weather‐resistant exterior wall envelope.

• Flashing

– Shall be installed at the perimeters of exterior door and window assemblies, penetrations and terminations of exterior wall assemblies, exterior wall intersections with roofs, chimneys, porches, decks, balconies, and similar projections … and similar locations where moisture could enter the wall.

10

Air Control Layer

Air Barrier Material Testing

• ASTM E2178 Air Permeance of Building Materials

• 1.0 m x 1.0 m specimen with no seams or transitions

• Must achieve less than 0.02 L/(s*m2) @ 75 Pa

11

Air Control Layer

Air Barrier Assembly Testing

• ASTM E2357 Air Leakage of Air Barrier Assemblies

• 8.0 ft x 8.0 ft wall with penetrations/transitions

• Includes wind cycling

• Measures infiltration and exfiltration

• Must achieve less than 0.2 L/(s*m2) @ 75 Pa

Vapor Control Layer• International Building Code and International Residential

Code require vapor retarders for protection of construction assembly.

13

Thermal Control Layer

• IECC requires opaque building enclosures to be insulated based on climate zone.

• Insulation between studs not enough due to thermal bridging.

• Continuous insulation (ci) required to minimize thermal bridging

Section II: Continuity of Control Layers

17

Continuity of Control Layers

• Assuring Integrity

– Look at complete building

– Understand compromising one barrier may compromise others

– Control layers can be single function/multiple product solutions,

OR

– Multi‐function/single product solution

Continuity of Control Layers

Non‐continuous conditions create performance risk

– Transition from one material to another

– Change in plane

– Penetrations/interruptionsin the control layer

19

Identifying the Building Envelope

• Start at one corner of the building

• Draw a continuous line around the building enclosure.

• Circle the changes in plane or potential discontinuity

20

Construction Detailing

• Writing “continuous” on a design detail or specification is not quite enough

• Buildings need to be designed and detailed to create continuity

• Details are critical

Section III: Choices in Control Layer Systems:Impact on Continuity

22

Choices in Control Layer Systems

Multiple products / Multiple layers

• Each of four control layers may be specified and installed separately

• Each needs to be compatible with each other and the building structure

• Each are tested separately

• Each needs to be assured to be continuous across all conditions

• Each needs to be durable

23


Single Product, Multi‐function

• Structural sheathing panels with integrated:– Weather‐Resistive Barrier (WRB)

– Air Barrier

– Vapor permeability

– Optional continuous insulation barrier

• Membrane fused to the structural panel during manufacturing

• Installation can be simpler and quicker

• Reduced labor time and skill required

Assuring Continuity of Assembly

• Seams of integrated panels are sealed with self‐adhering tape

• Openings and penetrations can be addressed with sealants or liquid flashing

• Flexibility of tapes and sealants allows for full conformity and continuity of control layers.

• Accomodates structural gaps while assuring control layers are intact.

25


Assuring Continuity of Assembly

• Windows and door openings require special

attention for continuity of control layers

How to attach?• Fastened the same as OSB/Plywood sheathing

• Printed fastening guide shows standard 6”/12” nail spacing

• Fastener Types (any code-recognized fastener)– Nails (6d or 8d common)– Staples (15 ga, 16 ga)– Fastener length and schedule varies by panel

thickness.

2015 IRC, TABLE R602.3(1) FASTENER SCHEDULE FOR STRUCTURAL MEMBERs

Fastening

Edge Profile

• Sheathing edges should be spaced a minimum 1/8” to allow for wood expansion/contraction with changes in humidity.

• The 8’ dimension has a Tongue and Tongue edge profile

• While this guideline is a recommendation, failure to incorporate an expansion gap can result wavy wall/roof lines.

• Fasteners installed with their heads penetrating into the moisture‐resistive barrier

• Taping/sealing is not required

• Overdriven fasteners do not compromise panel performance/warranty.

• Exception: fasteners that are more than ½ way through the depth of the panel.

Conclusions

The Key to Continuity is Detailing

• All building conditions where there is a change of any type need to be addressed.

• All control layers must be detailed and constructed to be continuous.

58

Conclusions

Integrated Products can Simplify Continuity• Single sheathing products can provide water‐resistive, air, and thermal control layers.

• Coordinated tape, sealant, and liquid flashing assure a complete assembly solution.

59

Conclusions

Integrated Products can Mitigate risk

• Single source for field support

• Single manufacturer warranty

• Typical OSB resins like phenol formaldehyde (PF) simply glue strands together with physical bonds (like velcro). PF and the wood remain chemically the same after pressing.

• With AdvanTech, MDI reacts with the water in the wood transforming it to polyurea.

The bond is a chemical bond which is very strong and highly resistant to water.

Smaller amounts of the MDI may react with the wood transforming it to polyurethane.

• Polyurea has the same water resistance properties as polyurethane

• MDI = Methylene diphenyl diisocyanate.
