It is easy for contractors and architects to determine the allowable movement capabilities of a joint system since the test standards, which are either ASTM E or ULused to investigate the performance of…. This patented system is comprised of U-shaped steel brackets for support of curtain wall insulation that are secured to the vertical curtain wall mullions without the need to drive screws into the mullions.

Self-locking fasteners are used to secure the insulation panels in place. The same holds true with construction and how things are being designed.

The exterior wall envelope is a system or assembly of exterior wall components, including exterior wall finish materials, that provides protection of the building structural members—including framing and sheathing materials, and conditioned interior space—from the detrimental effects of the exterior environment.

The exterior wall envelope must be designed and constructed to prevent damage from rain and snow, wind and other weather events. The IBC requires prevention of water accumulation within the wall assembly by providing a water-resistive barrier behind the exterior veneer, and a means for draining water that enters the assembly to the exterior.

Protection against condensation within the exterior wall assembly must also be provided. There are exceptions for when weather protection is not required, such as for certain concrete and masonry walls.

One option for providing code mandated weather protection for exterior walls is through performance testing for water penetration and air leakage. The IBC does not require a means of drainage to be provided for the exterior wall envelope when a representative test sample has been tested to resist a two hour simulated wind driven rain, including joints, penetrations and intersections with dissimilar materials.

This test is used to determine the resistance of exterior windows, curtain walls, skylights, and doors to water penetration when water is applied to the outdoor face and exposed edges simultaneously with a uniform static air pressure at the outdoor face higher than the pressure at the indoor face. The exterior wall envelope design shall be considered to resist wind-driven rain where the E testing indicates that water did not Exterior Wall Weather Protection Section UL performance testing helps designers and code authorities achieve code compliance.

This test method is for tests with constant Exterior Wall Weather Protection temperature and humidity across the specimen, and is intended to measure only such leakage associated with the assembly and not the installation.

The test method can be adapted to evaluate the overall installation if needed. Field testing demonstrates the building envelop systems meet code requirements for water and air resistance as well as ensuring designers and owners that these systems are safe, durable and energy efficient.This tape, as the name suggests, is a fire-resistant construction material that is designed to slow or prevent household fires.

Once you have measured, cut and hung your fire-resistant drywall, it must be taped and at least one coat of joint compound applied for the proper installation and fire rating. Purchase several rolls of fire tape from a hardware or contractor supply retailer.

Exterior Wall Weather Protection

Fill a clean paint tray with tap water. You can also fill a bathtub or sink with 1 or 2 inches of water. Hold the fire tape roll up the the wall near the joint between the mounted drywall panels, and unroll enough fire tape to cover the seam from top to bottom. Cut the fire tape with scissors. Dip the fire tape into the water, turning it over once so both sides are moistened but not soaked.

Do not submerge and leave the fire tape in the water; you only need to dampen it. Place the dampened fire tape against the drywall seam, and smooth it from top to bottom with a drywall knife. Use the knife to both adhere the fire tape so it's flat and also to remove any excess water. Allow the dampened fire tape to dry for between five and 10 minutes before continuing, and then spread joint compound directly over the dried fire tape with a drywall knife.

Let the compound dry. Abrade and smooth the first coat of joint compound using fine-grit sandpaper, and then apply a second coat of joint compound with a drywall knife. After the second coat dries, sand it smooth to finish the fire tape installation. Owen Richason grew up working in his family's small contracting business.
