Sealing the Building Envelope–Principles, Products & Practice

May 30 @ 1:00 PM - 2:00 PM EDT

In this presentation, we will discuss forces that cause moisture ingress: Raindrop Momentum, Gravity, Capillary Action, Surface Tension, Air Pressure Difference Learn where moisture gets in: Through Cladding (Porosity of Cladding), Improperly Sealed or Failed Joint Seals, Poorly Detailed or Executed Roof-to Wall Interface, Window Assemblies that are Poorly Designed and/or That Do Not meet ANSI Requirements for Wind Driven Rain or Hurricane Forces, Poorly Designed Vents, HVAC Units, and Other Envelope Penetrations. We will discuss types of joints; Structural Expansion Joints and Abutment Joints between Structures (ex. New and Existing), Joints at Penetrations to the Envelope (Windows, Doors, Vents, HVAC Units), Joints between Dissimilar Materials, Joints at changes in roof lines, building shape or structural systems, Joints in cladding panels.

We will also explore fundamental design issues affecting joint sealing: Existence and Emphasis and Sizing & Movement: Allowable Construction Tolerances, Relationship of Calculated Movement to Movement Capability of a Product Type, Failure to Design in Other than Cross- Section, Specification of Competitive Technologies, Continuity & Communication. We will also discuss joint sealant product types: Compression Seals, Strip Seals, Caulk & Backer Rod, Pre-compressed Sealants, Hybrid Sealants -Pre-Applied & Field-Applied. Last, we will discuss innovation and design versatilty: Double Sided vs Pre-Applied Binary Sealants, Watertight & Fire Rated Joints achieved with a Single Installation, Factory Fabricated Universal 90’s and R-value, STC & OITC ratings, and longevity; also installation and quality management.

Learning Objectives:

  1. Delve into why buildings leak
  2.  Consider your role in the building process
  3. Explore which product technologies are available
  4.  Discover how expansion joints integrate with different building systems.
