To disregard such movements in designing the wall is an urgent invitation to trouble. The effect of temperature changes is of course uniquely significant, because of the relatively high coefficient of expansion of aluminum, but the amount of such movement is predictable.
In a sheet of glass used alongside the aluminum the amount of movement will be less than half as much. Movement due to the other causes mentioned are generally not accurately predictable, but may be equally significant.
It becomes axiomatic, therefore, that the secret of a functionally successful curtain wall lies in the design of its joints. Consequently, the detailing of the joints is the most critical, and often the most difficult aspect of any curtain wall design.
This is seldom the case. The larger the units, or the longer the members, the greater will be the amount of movement to be accommodated at each joint, and this tends to complicate, rather than simplify the joint design. Provision must be made, of course, for both vertical and horizontal movement in the plane of the wall, either by some kind of slip joints or bellows action. In some situations they can be absorbed, to some degree at least, by increased stress within the member, resulting in a calculated deformation, and often they are accommodated by a combination of stress and deformation.
Except in a few cases, however, reliance upon stress increase alone to accommodate expansion is not advisable, as excessive bending or buckling may result. These drawings illustrate three ways this may be done. It depends in large measure on adequate provision for movement, and is closely related to proper joint design. Undoubtedly, a major share of difficulties experienced with metal curtain wall over the years has been due to the lack of weathertightness.
Water leakage was an all-too-common occurrence in the earlier walls, due to faulty design, materials or workmanship, or a combination of these. But with improved materials and design techniques its prevention has now become the rule rather than the exception. By comparison, excessive air leakage is less critical and more easily prevented.
High winds cause rain water to flow in all directions over the windward surface of a wall, and on surfaces of impervious materials much of it tends to collect at the joints-the major points of vulnerability. Early in the history of metal curtain wall experience it became apparent that to provide all joints at their outer surface with a permanently waterproof seal was essentially impossible, because of their continual movement, and this approach to weathertightness was soon abandoned.
Instead, two other methods have been developed for preventing leakage through the wall, and either of these, when intelligently applied, is highly dependable. The other is the "pressure equalization" method, a more recent development in metal curtain wall technology. Both of these methods are applicable to the design of windows as well as complete wall systems.
AAMA CW-DG The internal drainage method is based on the philosophy that it is impractical if not virtually impossible to totally eliminate, for any length of time, all leakage at all points in the outer skin of the wall, but that such minor leakage can be prevented from penetrating to the indoor face of the wall or even remaining within the wall.
This is accomplished by providing within the wall itself a system of flashing and collection devices, with ample drainage outlets to the outdoor face of the wall. Briefly, it requires the provision of a ventilated outer wall surface, backed by drained air spaces in which pressures are maintained equal to those outside the wall, with the indoor face of the wall being sealed against the passage of air.
The successful use of these methods depends on a clear understanding of the action of wind driven rain, careful detailing and, of course, proper installation. And in both cases ample weepholes or drainage slots, strategically located and properly baffled, play a critical role.
Drawing C shows a still more effective method of eliminating condensation on the interior faces of framing members, the provision of a thermal break within the member itself. Generally these relate to the control of the environment within the building-other important aspects of the filtering function of the wall.
Among the more important of these, the following should be noted: 1. Moisture Control Because metal and glass are not only impermeable to moisture, and thus highly efficient vapor barriers, but also have low heat retention capacity, the control of condensation is essential in any metal curtain wall design. An understanding of the causes of condensation, where it will likely occur, and how to minimize its potential damage is essential, if trouble is to be avoided.
But to explain these matters is beyond the scope of this summary review, intended only to flag out the importance of the matter. In capsule form, the important precautions to be remembered are these: AAMA CW-DG A vapor barrier should be provided on or near the indoor side of the wall; Impervious internal surfaces should be sufficiently insulated to keep them warmer than the dew point of the air contacting them; Provision should be made for the escape of vapor to the outdoors, and The wall should be so detailed that any condensation occurring within it will be collected and drained away.
Thermal Insulation In some cases the insulating value of the wall may be one of the major design considerations. Whether to reduce heat loss and prevent condensation in cold weather, or to minimize heat gain and air conditioning cost in hot weather, reduction of the overall U-value of the wall is usually a good long-term investment.
Metal and glass are materials which inherently have low resistance to heat flow, but with proper attention to details aluminum curtain walls can be designed to provide good thermal performance.
Page 15 Sound Transmission Under normal conditions, even in densely built urban areas, metal curtain walls compare favorably with any other wall construction having equivalent fenestration, as a barrier to airborne sound.
According to the law of mass, the transmission of sound through any barrier is inversely proportional to the mass of the barrier, and any lightweight construction such as metal curtain wall can claim no natural advantage as a sound barrier. But with careful detailing, based on an understanding of the principles of sound transmission, aluminum curtain walls have been designed to provide quiet enclosures near many airports.
It must be remembered that the efficiency of a barrier to airborne sound depends, in large degree, upon its weakest link, and the weak links in most walls are glazed areas and openings, however small the latter may be. Where a high degree of sound insulation is required, air leakage through the wall must be minimized, and double glazing, well separated and sealed, is usually essential. But because of the nature of its component materials the technology of its design involves some special considerations of major significance.
Chief among these are structural integrity, provision for movement and weathertightness, and the latter two in particular require careful attention to details. Care must be taken also to prevent condensation within the wall itself. In the structural design of aluminum curtain wall, stiffness rather than strength usually governs, and because the wall does not rely on its weight to provide stability, its anchorage to the building frame must be designed with due regard to both the suction and pressure effects of wind loading.
Because of thermal effects and other causes, substantial movements occur at many of the joints between its parts, and provision must be made to accommodate these movements without jeopardizing the integrity of the wall. And because the wall materials are impervious to water, the major impact of heavy rains is concentrated at the joints also. With the dual requirement of accommodating movement while still preventing leakage, joint design becomes the key to wall performance, and the most critical aspect of design.
Weathertightness, often regarded as the chief measure of acceptable performance, is achieved, not by attempting to maintain a completely unbroken impervious membrane at the other wall surface, but by other more dependable means. Just as with any other type of exterior building wall, thermal insulating value may be an important consideration in many locations and the necessity of low sound transmission is also sometimes a requirement affecting wall design. Such requirements are satisfied in aluminum curtain walls by applying in their design the accepted principles of heat flow and acoustics.
The performance of any metal curtain wall depends in large measure upon how well its designer understands not only the principles of natural laws but how they affect the detailing of the wall. In the belief that more information on those matters will be helpful, some of the subjects discussed only briefly here will be examined in much greater depth, with supporting data, in future publications. Some architects who have been using metal curtain wall for years have come to recognize this, and have learned by experience how to minimize their costs in detailing the wall, yet insure the achievement of their design concepts.
But those less familiar with metal curtain wall construction, or perhaps using it for the first time, are likely to spend a great deal of time in minute detailing, only to discover later that some of their labor was wasted.
Often the details and joinery of the wall as shown on the shop drawings for their approval, and as later built, differ from those they provided, yet are completely acceptable. This seeming inconsistency can readily be explained. The architect cannot be an expert in all fields; he can hardly be expected to know as much about metal-working techniques as those who have made it their life's work. But he is the expert in matters pertaining to aesthetics, and he is responsible for establishing performance requirements.
Insofar as his details reflect these concerns, the architect's requirements, providing they are reasonable and logical, should be faithfully met. Manufacturers are usually pleased to provide such advice and counsel at no obligation, and prefer to have the opportunity to offer suggestions while the concept is still fluid.
Reliable manufacturers of aluminum curtain wall make every effort to satisfy the architect's stipulations in respect to the constituent materials, the appearance and the performance of the wall, though they may sometimes question the wisdom of some of his decisions. They quite naturally prefer, however, to meet these criteria by methods which they have found by long experience to be the most dependable and efficient. The manufacturer sincerely desires not only to assist the architect in the development of his design, but to help him present its concept and details in such a manner that will minimize waste effort on his part, yet insure a clear understanding of his intent.
In the hope of clarifying this interest, it is the purpose of this article to recommend efficient detailing procedures and to call attention also to certain considerations often overlooked in architects' designs. With their extensive experience and their knowledge of production processes and installation methods, the wall fabricators are able to analyze the general concept, recognize potential problems and offer suggestions which will aid the designer, facilitate production and usually result in cost savings.
The failure to seek such advice, and profit by it, often leads to difficulties later. It's not unusual to discover, for example, after the job is out for bids, that some parts of the wall, as detailed, are very difficult or practically impossible to produce, or that they are structurally inadequate; that the size of the wall units is such as to create transportation problems; that the tolerances allowed in the design are unrealistic, or that there isn't enough clearance provided to permit easy installation.
The need for, and value of, the manufacturer's advice varies, of course, with the size, importance and complexity of the job in question. If the wall is to be custom designed, the importance of competent advice by qualified manufacturers is usually much greater, regardless of the size of the job. Due to his limited experience, the architect, working alone, may not recognize the importance of such matters, which are critical considerations in metal curtain wall design.
But with the aid of competent advice by manufacturers during the early stages of design, he can avoid many of the difficulties that might otherwise be encountered. Standard Walls For obvious reasons, less detailing is usually required for a standard type of wall than for custom wall, regardless of the size of the building.
It is essential, of course, that the architect establish the wall pattern and locate all principal members, designate the infill materials to be used and the finishes required, the type, size and location of operable window units, if any, and provide details of perimeter conditions where the wall adjoins other materials. The cross sectional dimensions of framing members should be shown, as in most standard systems a range of sizes is offered.
In selecting the sizes of principal members strict attention should be paid to the manufacturer's data regarding their structural capacities, and these capacities should not be exceeded.
The type and thickness of glass, and the material to be used for opaque panels must be shown, but the specific glazing methods to be used will likely vary with different wall manufacturers. It should be made clear, however, that only those methods meeting the specified performance standards will be accepted. Figure 11 illustrates the extent of detailing normally required for a small two-story standard wall which is to be bid competitively.
There is no need to detail standard members, but in cases where such members are to be modified, sufficiently large scale details [at least 75 mm 3 in scale; preferably larger] should be provided to clearly explain the nature and extent of modification.
In many installations the surround conditions are unique; there may be special sill conditions, special corner AAMA CW-DG treatments or a specially designed coping. It is essential that all such conditions be clarified by large scale details showing, not the fabrication and joinery, but the profiles desired, along with all critical dimensions and the clearances to be provided. Most manufacturers of standard wall systems provide large scale or full size section drawings, and often engineering data as well, to facilitate such detailing.
If the work is to be done under a negotiated contract, with the wall manufacturer selected in advance, the use of that manufacturer's details in preparing the architectural drawings will, of course, present no problem. But usually competitive bids, by fabricators of several comparable systems, will be required and this may raise questions as to how the details should be prepared.
Unlike structural steel sections, the sections used in standard curtain wall systems offered by different manufacturers are not identical. They are "standard" as far as their own producer is concerned, but not a standard of the industry. But there is a good deal of similarity in general appearance between the sections offered by one manufacturer and those offered by several of his competitors.
If the performance requirements and the aesthetic effect desired are clearly defined, the architect will generally experience little difficulty in obtaining a sufficient number of bids to ensure a good competitive price. This may be done by listing several acceptable bidders, although the details shown represent one specific system. To ensure that the bids presented by competitors represent work of acceptable appearance and quality the architect should specify that they submit for his approval, well in advance of the bid date, sufficient details to show how they propose to construct the wall.
It must, of course, be completely detailed, but the bulk of this work may be done by the manufacturer rather than the architect, as will be explained. Generally the architect has two options as to how he may handle this aspect of custom wall work.
He may specify that selected bidders submit with their bids certain drawings explaining in detail their proposals, or he may choose to provide his own complete details on which all bids are to be based. In either case he controls the aesthetics of the design and it is his responsibility to establish the performance requirements of the wall and see that they are met. The choice between these two procedures depends on several factors: the time allowed for the preparation of bids especially on jobs to be bid competitively ; the size of the job; the expertise of the architect's staff, and above all, the prior determination as to whether the manufacturers to be asked to bid will be willing to provide proposed details for the job in question.
Each of the two procedures has its advantages and disadvantages, as will be explained. Under the submission procedure each bidder submits for the architect's approval "submission" or "proposition" drawings showing how he proposes to construct the wall. All such drawings are, of course, developed from the design provided by the architect in his contract documents.
The architect's details must therefore clearly show the aesthetic requirements, e. He should not undertake the complete detailing of all parts of the wall and their methods of assembly. This becomes the obligation of the bidders, each of whom will likely propose details differing not only from each other but from those which the architect would have prepared.
The drawings submitted by the bidders usually include only representative typical details sufficient to show the proposed character of construction; they are by no means complete shop drawings. At a later stage, when the successful bidder submits his complete shop drawings, all aspects of the design will, of course, be subject to the architect's approval.
An example of drawings used in this procedure is shown in Figure Note that in at least one of the proposed designs the location of the finished plaster in respect to the glazing bead is questionable. This method of developing custom wall details is commonly used with negotiated contracts, but is applicable also to jobs bid competitively, provided that sufficient time is allowed in the bidding period for bidders to prepare their proposed details.
It must be recognized, however, that the proposals submitted by the various bidders may very likely use differing methods of glazing, anchorage or other details affecting the work of collateral trades. It becomes essential, therefore, that for each submission approved as being acceptable, information as to how that design will affect the work of other trades be provided to subcontractors bidding that work, so as to avoid either the duplication of bids or the omission of essential items.
While this "submission procedure" does not require complete detailing by the architect, it does impose on him the necessity of being able to intelligently evaluate the merits of each proposal and judge whether it will provide an attractive and trouble-free wall.
In cases where the General Contractor has already been chosen, he should also be available to advise as to the relative merits of the proposals taking into account their overall cost effects. It is essential, in any case, that the architect have a knowledge of the fundamental requirements of good curtain wall construction and that he understands how the materials going into it will react under the conditions to be imposed upon it.
Under the alternative procedure, when submission drawings are not required of the bidders, the architect's details must be much more complete, as they establish the basis on which all bids are tendered. It is the architect's responsibility in this case not only to provide details showing the materials and finishes to be used, the methods of glazing, provisions for accommodating movements, methods of anchorage, all critical dimensions and profiles, and clearances to be provided, but also to verify the structural adequacy of his design.
Even under this procedure, however, he should not attempt to provide details so complete that they may be used as shop drawings. He should leave to the discretion of the fabricator the choice of certain fabrication and connection details, the internal configuration of extruded sections and the location of inconspicuous non-working joints.
He should anticipate, too, that some of the bidders may suggest certain revisions in his details, and should be receptive to such suggestions. If they are offered and accepted during the bidding period, all other bidders should, of course, be so advised. Most architects, though, can claim no expertise in metal fabrication techniques. For them to insist upon the manufacturer following details which he considers impractical not only places the burden of responsibility upon themselves but is likely to result in dissatisfaction.
Frequently the wall manufacturers bidding the work suggest minor changes in the design or detailing of a curtain wall which result in improvements, and usually a savings of cost. The following case histories of actual experience are examples of such instances.
When costs had to be reduced to meet the budget, the manufacturer, by engineering analysis, found that this section was far stronger than necessary and wasteful of material. The dimensions to the outer edge of the groove and the width of the masonry opening were shown to be identical. The manufacturer pointed out that, since no allowance was made for working tolerances, the strict alignment intended could not be achieved and the aesthetic effect of the groove would be lost.
But the architect could not agree, so special extrusions were made, and with special tooling the design was provided. The result, as exaggerated at B, was that in some places the groove was entirely covered, while in others the jamb face beyond the groove was exposed. The manufacturer suggested that consideration be given to relocating the mullions as shown in Drawing B, making all of the glazed units the same width.
This suggestion was accepted, resulting in a substantial saving. CL COL. C L COL. In this case the value of the metal saved far exceeded the increase in die and extrusion costs. The manufacturer suggested changing to a lighter extrusion having the same exterior profile, and adequate stiffness, as shown at B.
Although this is a more complex configuration, incorporating a hollow element, its use resulted in a saving of 45, kg , lbs of aluminum on this one job. Also, by substituting a snap-on cover on the indoor face, the modification eliminated the field labor required for the screw assembly of mullion parts.
Here the architect required a color anodized mullion section of such depth that it required two extrusions, as shown at A. The manufacturer, foreseeing possible problems in color matching, suggested the modified design shown at B, pointing out that the recess in the side face of the mullion would serve not only to conceal the connecting screws but also to make less noticeable any slight variation in color between the two parts.
The architect agreed, and the modified design was adopted. As will be seen, the original design included an applied rectangular member used to frame and accent each mm x mm 4 ft-3 in x 11 ft-3 in unit.
Later the architect was asked to design another building using a very similar wall design, and the same fabricator was given the job.It also incorporates content from several other related AAMA publications for ease of access.
