Trapezoidal
Structural Standing Seam Roof Systems
The snap-together system, Ultra-Dek®, and field seamed system, Double-Lok®, were engineered from concept to installation for strength, durability, and weatherability. The standing seams are a full three inches above the lowest part of the panel, well above the water level as it flows off the roof. The seams have factory-applied mastic to insure a secure, weathertight seam.
BEGINS AND ENDS IN A HIGH
The rake/gable at both ends of each roof system finish with a 3” high
standing seam, avoiding the necessity of finishing in the low, flat part
of a panel where the greatest possibilities for leaks occur in most other
systems.
CONCEALED FASTENING SYSTEM
The standard offering for the Ultra-Dek® and Double-Lok® systems
is a floating clip that cannot be installed unless the tab is centered
in the clip base. This feature provides for maximum efficiency of the clip
and panel.
Special conditions may require the use of the unique Articulating Clip, which is designed to eliminate binding and friction in a misaligned substrate application.
UPLIFT RATINGS
Both systems carry Underwriters Laboratories Fire Resistance and Wind
Uplift (UL90) ratings covering a wide range of roof designs. In addition,
the Double-Lok® system meets Class 1-60, 1-90, and 1-105 ratings as
tested under Factory Mutual Research Corporation Standard 4471. The Double-Lok®
system has met all test requirements specified in CEGS 07416 Standing Seam
Metal Roof System guide specification. Contact MBCI for parameters relating
to each panel profile.
APPLICATION
Panels can be installed before or after the exterior walls are in place.
All trim is attached after the roof is installed. With a recommended minimum
slope of 1/4 :12, these roof systems can be used on all types of construction:
masonry, metal or wood for either new construction or retrofit.
Articulating Clip Eliminates Binding and Friction
There are many styles of standing seam clip systems available today. However, MBCI offers the only clip that articulates as well as floats which eliminates binding and friction. This clip is available for both the Ultra-Dek® and Double-Lok® systems.
Two floating clips are available with each system. When added insulation is required, a high floating clip is used with a 1" thermal spacer. A low floating clip can be used without the thermal spacer.
ELIMINATES BINDING
This four piece clip articulates between the base and intermediate
section without binding. Typically, binding on the clip is attributed to
misaligned or out-of-square purlins or bar joists. The bind restricts a
standing seam roof from properly floating the way it was designed.
ELIMINATES FRICTION
The floating section of most clip systems grabs only the top portion
of the male leg of the panel while the fixed section of the clip supports
the bottom male leg. When expansion and contraction occur, the top portion
actually moves with the panel as the bottom portion remains fixed. This
creates friction or drag between the clip and panel greatly restricting
movement. The articulating clip, which allows for 2 1/2"of slide per clip,
supports both the top and bottom of the male leg eliminating the friction
and allowing the panel to float freely as it was designed.
ROOFING SYSTEM
FEATURES AND BENEFITS
1. DESIGN INTEGRITY
MBCI’s Ultra-Dek® begins and ends in the high, reducing
the risk of leakage at the rake that can occur when finishing in the low.
The panel seam is sealed with a factory-applied hot-melt mastic, a superior
grade to mastics applied in the field.
2. FLOATING ROOF
The Ultra-Dek® roof was designed to cope with the forces
of expansion and contraction. This is accomplished by allowing the panels
to freely move up and down the roof slope. Due to this design feature,
the system offers no diaphragm capabilities or purlin stability.
3. CLIP SELECTION
A large selection of clips is available for various types of construction.
The articulating clip eliminates the binding and friction during panel
expansion and contraction caused by a misformed, misaligned or improperly
erected substructure. The clip provides a 3/8" clearance at the purlin
to reduce water ponding on low pitch roofs. Constructed from 12 gauge material,
this clip is an integral part of maintaining panel module within the floating
system.
4. UL 90 RATING
MBCI’s Ultra-Dek® roof system has 10 different UL 90 construction
numbers, each of which are available with several options.
5. FIRE RESISTANCE RATINGS
The roof system qualifies for use in several UL design assemblies and
carries a UL "CLASS A" rating.
6. SIMPLICITY
No troublesome batten cap is needed. The panels simply snap together
forming a self-locking seal.
7. FLEXIBILITY
MBCI’s Ultra-Dek® roof system offers welcome flexibility
to the erector. Wall covering can be erected before or after the roof is
installed. Panel installation is an uninterrupted procedure.
8. EASE OF INSTALLATION
The erector has the option to sheet each side of the roof separately
or both sides simultaneously, which greatly increases the speed and convenience
of erection. Being reversible end-for-end, sheets do not have to be special
ordered for each side of the building. No field notching of panels at endlaps
or ridge is required.
9. FORGIVING SYSTEM
The Ultra-Dek® system design allows for the roof to be finished
in the high when an out-of-square condition or other factors cause the
roof to terminate up to 4" from the steel line.
10. BUILDING LENGTH
Odd, as well as even, footage buildings can be terminated in a major
rib with the use of our 12" and 18" panel or in the low by field bending
the panel.
11. PREPUNCHED PANELS AND COMPONENTS
MBCI’s prepunched system, combined with self-engaging back-up plates,
assures panel module and speeds up roof installation.
12. DURABILITY
Every unpainted panel is manufactured from Galvalume Plus®, your
assurance of the MBCI commitment to quality.
13. COLOR AND FINISHES
Ultra-Dek® is available in a wide variety of popular colors
in three different paint systems.

CAUTION
Application and design details are for illustration purposes only,
and may not be appropriate for all environmental conditions or building
designs. Projects should be engineered to conform to applicable building
codes, regulations, and accepted industry practices.
CAUTION
Ultra-Dek® is a snap together system. Use of a mechanical
seaming tool on the Ultra-Dek® system will void all warranties.
It will greatly facilitate DESIGNING, QUOTING, ORDERING, or ERECTING the MBCI Ultra-Dek® roof if you determine which system you need or have, based on building width and insulation requirements.

Floating clips have a maximum of 1" movement each direction. Articulating
clips have a maximum movement of 1 1/4" each direction. Thermal calculations
should be performed for each project to ensure that the thermal movement
of the roof is not more than the clips can handle.
FOR ROOF PITCHES GREATER THAN 4:12, CALL MBCI
NOTES:
1. The above applies to pre-engineered metal buildings.
2. Bar joist construction (all widths) requires a floating system.
3. 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 acoustical consideration. Contact
your architect and/or engineer for proper acoustical design.
4. All metal roofs should be designed by a registered, professional
engineer for loads specified by the governing code, including the higher
pressures encountered at the edge zones of the roof.
