Exterior Envelope – Doing It Right A seminar aimed at contractors and architects who want to expand their knowledge about the IECC’s exterior thermal envelope requirement for exterior wall assemblies when combined with ASTM…
Restricting or controlling water whether it’s a gas, liquid, or solid state is a critical concern in the design of the exterior envelope. Minimizing the potential for water collecting within a stud cavity is…
CONTINUOUS INSULATION EXPANDED POLYSTYRENE INSULATION (EPS) Composition: Nominal 1.0 lb/ft3 Closed Cell Expanded Polystyrene Size: Min. 3/4” to 12” max. 24” wide x 48” or 96” (depending on system) Application: Over sheathing substrate on…
This section will cover the various codes and standards that regulate the design of the exterior envelope. Starting with the codes is a discussion of the International Energy Conservation Code. This will be followed…
FIRE RESISTANCE There are four different fire resistive tests that cover wall system design. The main and oldest of the four tests is known as ASTM E119 Standard Test Methods for Fire Tests of Building…
TYPICAL EXTERIOR WALL SYSTEM The following are the primary components that together make up an exterior system: (1) INTERIOR SIDE FINISHING The most common interior finish is paint. Painting the interior cladding is fast,…
This category provides details of cold-formed steel framed assemblies used in exterior structural applications. Specific emphasis is on the integration of continuous insulation with a mutlitude of exterior finish materials on cold-formed steel framing. …
WATER – RESISTIVE BARRIERS The proper design and installation of water resistant barriers is becoming increasingly important. Water resistant barriers serve as a second line of defense against moisture (in its liquid state) entering…
