increases the need for these systems is today's energy requirements, which in some parts of the country, may force the designer to use up to as much as four inches of rigid insulation in the cavity. When running dew-point analysis in steel stud and non-breathable assemblies, it has become extremely popular to use rigid insulation in the cavity versus the old batt insulation in the studs to move that potential dew point out into the cavity area, thus minimizing condensation within the interior portion of the steel stud backup system. This concept has caused the need for increased thicknesses of insulation in the cavity, plus it has created the need for manufacturers to help the contractor in the field with attaching anchoring systems through the insulation and gypsum board.
Maybe the biggest change has taken place with regard to potential air and moisture infiltration in the wall assembly, and, more important, how we deal with keeping the building envelope as dry and energy efficient as possible. Anchoring systems certainly have become a major part of a successful building envelope, but not only from the anchoring standpoint. Today's anchors must be compatible and function with all different types of both breathable and non-breathable air and vapor barriers. It is critical that the barrier's integrity not be impaired, so as to maintain indoor air quality while also contributing to the structure's energy compliance. In some cases, such as steel stud assemblies, the anchoring system will normally penetrate the air/vapor barrier and must provide an additional seal against air and moisture penetration at the outer-most point of the backup system. In CMU applications, the air/vapor barrier must be able to effectively seal around the previously installed anchors. In all cases the air/vapor barrier and the anchoring system need to be able to function properly together, thus requiring careful consideration during design and product selection.
Another veneer that has gained tremendous popularity during the last few years is the use of an almost unlimited number of real and imitation stone products. Developing anchoring systems for all the various types of stone materials (natural or synthetic) from different parts of the country has created a situation where most anchoring systems need to be "engineered" for each specific application.
