Vertical Leg
Structural Standing Seam Roof Systems

The LokSeam®, BattenLok® and SuperLok® standing seam roof systems blend the aesthetics of an architectural panel with the strength of a structural panel. These panels have earned several uplift ratings assuring the reliability of performance. The designer is afforded a flexible tool to meet any design challenge.

ARCHITECTURAL/STRUCTURAL PANELS
LokSeam® is a snap-together system that was designed for transitions from roof to fascia for a continuous, uninterrupted appearance. A die-formed rib cover is available for use with this detail.

BattenLok® is a field seamed system that is also capable of transitioning from roof to fascia. Die-formed rib covers are also available for this product.

SuperLok® is a field seamed panel that combines a slim rib with exceptional uplift resistance. This panel has been designed to withstand the most rigorous conditions.

Each of these systems feature factory installed hot-melt mastic to insure weathertight seams. Striations are optional and encouraged for added aesthetic value.

CONCEALED FASTENING SYSTEM
A choice of concealed fastening clips is available for each panel system including UL rated clips. These clips hold the panels firmly in place without unsightly exposed fasteners. Each clip system offers the ability to accommodate thermal movement.

UPLIFT RATINGS
Each system carries the Underwriters Laboratories Fire Resistance and Wind Uplift (UL 90) ratings covering a wide range of roof designs. In addition, the SuperLok® system meets Class 1-90, 1-105, and 1-135 ratings as tested under Factory Mutual Research Corporation Standard 4471. The BattenLok® and SuperLok® systems have met all test requirements specified in CEGS 07416/ASTM E1592 Standing Seam Metal Roof System guide specification. Contact MBCI for parameters relating to each panel profile.

APPLICATION
Each of these systems are designed to be installed over open framing. However, the MBCI LiteFrame™, 5/8" plywood or a composite roof assembly may be used as alternate substructures. LokSeam® must be installed on roof slopes of 3:12 or greater. BattenLok® and SuperLok® must be installed on roof slopes of 1/2 :12 or greater.

ARCHITECT/ENGINEER INFORMATION - LokSeam® Panel

1. LokSeam® is a snap-together, integral batten roof system, available in three widths: 18", 16", and 12". Factory applied mastic inside of female leg of panel is standard.
2. The minimum recommended slope is 3:12. For slopes less than 3:12, call MBCI.
3. LokSeam® is a UL 90 rated, structural roofing panel. This panel can be installed directly over purlins or bar joists. It does not require a solid substructure for support (Caution: See Note 14)
4. Watertight and aesthetically pleasing endlaps may be accomplished through the use of swaged and prepunched panels. MBCI recommends the use of prepunched back-up plates at the endlap for weathertightness. Prepunching of the panels is available for the endlap condition only. (Swaged endlaps require the roof erection to proceed from left to right as viewed from the eave looking toward the ridge.) Roofs with no endlaps may be erected from either direction. For panel lengths over 40', please inquire. When using an alternate endlap detail, do not order panels with prepunched endlaps. (Endlaps for 16" LokSeam® are not available)
5. Panels can be installed on roofs with a transition by using MBCI’s die-formed rib covers.
6. Narrower widths, heavier gauges, striations and embossing minimize oil canning. Industry standard is 18" wide, 24 gauge. Oil canning is not a cause for rejection.
7. The substructure (eave to ridge) must be on plane with a tolerance of 1/4" in 20' and 3/8" in 40'.
8. All panels require end sealant at eave and valley conditions; however, for illustration purposes, this sealant is not shown on all drawings.
9. All drawings and trim dimensions in this information are based on a 1 1/4" wall thickness (“R” Panel) and a slope of 3:12. Other wall panel thicknesses as well as roof slopes may affect various dimensions on drawings and trim. If you have any questions, call MBCI.
10. The information here is believed to be correct and accurate. It should not be used for any specific application without being reviewed by a registered professional engineer. All metal roofs should be designed by a registered, professonal engineer for loads specified by the governing code, including the higher pressures encountered at the edge zones of the roof.
11. Avoid restricting the thermal expansion and contraction of the LokSeam® panels. (ie: Do not attach panels to the substructure at both the eave and ridge.)
12. LokSeam®panels are not designed to be work platforms. Avoid any unnecessary foot traffic on LokSeam® panels. If foot traffic is required, protect the roof panels by using some type of roof pad, temporary deck, or walkway.
13. When installing LokSeam® panels over open framing with blanket insulation: (A) install insulation parallel to purlins or joists, or (B) install insulation across purlins or joists and compress it with pinch bars. (An alternative to blanket insulation is a product called Low-E Insulation, manufactured by Environmentally Safe Products, Inc. For more information on this product, call MBCI.)
14. A vapor retarder may be necessary to protect roofing components when high interior humidity is a factor. The need for a vapor retarder, as well as the type, placement and location should be determined by an architect or engineer. The following are examples of conditions that may require a vapor retarder: (A) Projects where outside winter temperatures below 40°F are anticipated and where average winter interior relative humidity of 45% or greater is expected. (B) Building usages with high humidity interiors, such as indoor swimming pools, textile manufacturing operations, food, paper or other wet-process industrial plants. (C) Construction elements that may release moisture after the roof is installed, such as interior concrete and masonry, plaster finishes and fuel burning heaters.

CAUTION
Diaphragm capabilities and purlin stability are not provided by MBCI’s LokSeam® roof system. Therefore, other bracing may be required to conform to A.I.S.C. or A.I.S.I. specifications.

ICBO APPROVAL
The ICBO Evaluation Service, Inc. has approved the roofing system details, engineering, calculations, computer printouts, and product data. This information has been found to comply with the 1997 Uniform Building Code and is listed in evaluation report number ER-5409. A copy of this report is available upon request.

ARCHITECT/ENGINEER INFORMATION - BattenLok® Panel

1. BattenLok® is a mechanically seamed roof system. BattenLok® panels are 16" and 12" wide. Factory applied mastic inside of female leg of panel is standard.
2. BattenLok® is a structural roofing panel. This panel can be installed directly over purlins or bar joists. It does not require a solid substructure for support. The BattenLok® roof system has several different UL 90 construction numbers.
3. BattenLok® system is recommended for roof slopes of 1/2:12 or greater.
4. Weathertight and aesthetically pleasing endlaps may be accomplished through the use of swaged and prepunched panels. MBCI provides a prepunched back-up plate at the endlap for weathertightness. Prepunching of the panels is available for the endlap condition on 16" width panels only. Swaged endlaps require the roof erection to proceed from right to left as viewed from the eave looking toward the ridge. Roofs with no endlaps and less than 6:12 may be erected from either direction. For panel lengths over 40', please inquire.
5. Panels can be installed on roofs with a transition by using MBCI’s die-formed rib covers.
6. Heavier gauges, striations, embossing and installation over a solid deck minimize oil canning. Industry standard is a minimum 24 gauge material. Oil canning is not a cause for rejection.
7. Substructure must be on an even plane from eave to ridge to avoid panel distortion (1/4" in 20', 3/8" in 40' tolerance).
8. All panels require end sealant at eave and valley conditions; however, for illustration purposes, this sealant is not shown on all drawings.
9. All perimeter trim dimensions in this manual are based on a wall panel thickness of 1 1/4" (“R” Panel). Any variation from this wall panel thickness may affect the perimeter trim dimensions.
10. The information here is believed to be correct and accurate. It should not be used for any specific application without being reviewed by a registered professional engineer.
11. Drawings in this manual utilize the low fixed clip. Clips are available in low or high fixed, low or high floating and utility. Please use the reference chart below to determine the clip required for your particular job.
12. Avoid restricting the thermal expansion and contraction of the BattenLok® panels. (ie: Do not attach panel to the substructure at both the eave and ridge.) However, panels must be attached to the substructure at one end to prevent their sliding downslope.
13. BattenLok® panels are not designed to be work platforms. Avoid any unnecessary foot traffic on BattenLok® panels. If foot traffic is required, protect the roof panels by using soft soled shoes and some type of roof pad, temporary deck, or walkway.
14. WARNING: Light transmitting panels are not designed or intended to bear the weight of any person walking, stepping, standing or resting on them. MBCI DISCLAIMS ANY WARRANTY OR REPRESENTATION, EXPRESS OR IMPLIED, that any person can safely walk, step, stand or rest on or near these light transmitting panels or that they comply with any OSHA regulation.
15. A vapor retarder may be necessary to protect roofing components when high interior humidity is a factor. The need for a vapor retarder, as well as the type, placement and location should be determined by an architect or engineer. The following are examples of conditions that may require a vapor retarder: (A) Projects where outside winter temperatures below 40°F are anticipated and where average winter interior relative humidity of 45% or greater is expected. (B) Building usages with high humidity interiors, such as indoor swimming pools, textile manufacturing operations, food, paper or other wet-process industrial plants. (C) Construction elements that may release moisture after the roof is installed, such as interior concrete and masonry, plaster finishes and fuel burning heaters.
16. Typically, when wood decks are used, they are temporarily protected by the installation of a moisture barrier over the wood deck. If utility clips are to be used, the BattenLok® panel will lay tight to the wood deck. If tin tabs are used to attach the moisture barrier to the deck, they must be covered with duct tape or some other material to prevent them from rusting the back side of the panels. Also, plastic washers may “telegraph” through the panels.

It will greatly facilitate DESIGNING, QUOTING, ORDERING, or ERECTING the MBCI BattenLok® roof if you determine which system you need or have, based on building width and insulation requirements.

FOR ROOF PITCHES GREATER THAN 6:12, CALL MBCI
NOTES

1. The above applies to pre-engineered metal buildings.
2. Thermal calculations should be performed for each project to ensure that the thermal movement of the roof will not exceed the design of the clip.
3. Bar joist construction (all widths) requires a floating system and special considerations for thermal movement.
4. As with all standing seam roof systems, a sound insulator (EXAMPLE: blanket insulation) is required between the panel and substructure. Some composite systems require additional accoustical consideration. Call MBCI for further information.
5. Utility clips require the use of a low profile fastener, ie: pancake head.
