Detailing Transitions Between Air Barrier Materials
Transitions between air barrier materials are critical points of failure if not properly detailed. This article explains how to connect dissimilar materials such as sheathing membranes, liquid flashings, and pre-applied barriers. Overview Air barrier transitions occur where materials meet at changes in substrate, structure, or geometry. Ensuring continuous airtightness at these points is essential to […]
Continuous Insulation Systems for Energy Code Compliance
Continuous insulation (CI) is required by today’s energy codes to improve thermal performance. This article covers key materials, installation methods, and tested systems that reduce heat loss through the building envelope. Overview Continuous insulation refers to insulation installed without thermal bridges across all structural members, except fasteners and service openings. It significantly reduces thermal bridging […]
Acoustic Envelope Assemblies for Urban Schools
Sound control is essential in schools located in noisy city environments. This article explores acoustic envelope strategies and components that reduce noise transmission for better learning outcomes. Overview In dense urban settings, schools are often located near highways, subways, or airports—exposing classrooms to disruptive exterior noise. Designing envelope assemblies to block or absorb sound is […]
Fire-Resistive Joint Systems at Floor-to-Wall Connections
Prevent fire spread at critical building joints with tested fire-resistive joint systems. Explore UL systems, joint types, sealants, and installation tips for commercial and multifamily buildings. Overview Floor-to-wall joints are required to remain fire-resistive in many commercial and multifamily buildings. These junctions, found at slab edges and floor assemblies, can allow flames, smoke, and gases […]
Vapor Retarders in Below-Grade Waterproofing
Controlling ground-sourced water vapor is critical for long-term performance of basements, slabs, and foundation walls. Learn about vapor retarders, permeance levels, and compatible membrane systems. Overview Below-grade construction is constantly exposed to moisture vapor from the surrounding soil. When vapor barriers or retarders are not properly designed, this vapor can enter the building, increasing humidity, […]
Rain Screen Design for Cold and Mixed Climates
Rain screen wall systems provide superior moisture management and durability, especially in cold and mixed climate zones. Learn the key design principles and best product options. Overview Rain screens are an exterior wall construction method that creates a ventilated drainage gap between the cladding and water-resistant barrier. They are especially effective in cold and mixed […]
High-Performance Window Flashing Systems
Proper window flashing is essential for managing water at vulnerable building envelope openings. Explore the best methods, materials, and products used in today’s high-performance assemblies. Overview Window openings are one of the most common sources of water intrusion in building envelopes. To prevent costly leaks and damage, window flashing systems must be detailed correctly using […]
Thermal Bridging Solutions in Steel-Framed Construction
Reduce energy loss and condensation risks in commercial buildings by addressing thermal bridging in steel-framed wall assemblies. Learn how to use thermal clips, Z-girts, and CI strategies. Overview Thermal bridging occurs when materials that are poor insulators bypass or reduce the effectiveness of wall insulation. In steel-framed construction, framing members conduct heat easily, creating paths […]
Air Barrier Membranes: Self-Adhered vs Liquid-Applied
Compare two primary air barrier strategies for high-performance building envelopes. Learn which is best for your wall assembly, including recommended products and applications. Overview Controlling air leakage in building envelopes is critical for energy efficiency, indoor air quality, and moisture protection. Two of the most common air barrier membrane types are self-adhered sheets and liquid-applied […]
Best Cladding Systems for Multifamily Projects
Explore cladding system options for apartment buildings, condos, and townhomes. Discover top product picks, installation strategies, and material performance for high-density housing. Overview Exterior cladding is a critical design component for multifamily buildings, offering both weather protection and architectural appeal. In dense urban and suburban environments, cladding must balance durability, fire resistance, code compliance, and […]
