IMPORTANT READ THIS FIRST

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-DekŪ is a snap together system. Use of a mechanical seaming tool on the Ultra-DekŪ system will void all warranties.
In order to design, quote, or order an Ultra-DekŪ roof system, you must determine which system you need, based on building width and insulation requirements.

Low Fixed System -

Double slope buildings over 200' wide or less and single slope buildings 100' wide or less, with or without a 3/8" thermal spacer.  See Insulation/Thermal Spacer Selection Chart below.

High Fixed System -

Double slope buildings over 200' wide or less and single slope buildings 100' wide or less, with 3/8", 5/8", or 1" thermal spacer.  See Insulation/Thermal Spacer Selection Chart below.

Fixed systems utilize fixed clips that do not allow the roof panels to float on the substructure.  For this reason, use fixed systems only on pre-engineered metal buildings with purlins, subject to the building width restrictions outlined above.  Do not use fixed systems on buildings with bar joist construction, wood decks or metal decks.

Low Floating System -

Double slope buildings over 200' wide or single slope buildings over 100' wide, with or without a 3/8" thermal spacer.  See Insulation/Thermal Spacer Selection Chart below.

High Floating System -

Double slope buildings over 200' wide or single slope buildings 100' wide, with 3/8", 5/8", or 1" thermal spacer.  See Insulation/Thermal Spacer Selection Chart below.

Thermal calculations should be performed for each project to ensure that the thermal movement of the roof is not greater than the floating clip's capacity.  Various densities of blanket insulation may affect the installation and or the appearance of a metal roof system.  The installer is responsible for selecting the proper clip and thermal spacer for their conditions.

6" Insulation N/A 3/8" Thermal Spacer

NOTES:

  1. As with all standing seam roof systems, a sound insulator (example: blanket insulation) is required between the panel and substructure to prevent "roof rumble" during windy conditions. Some composite roof systems may require additional acoustical consideration to ensure that thermal vibration noises are isolated from the building interior. Contact your architect and/or engineer for proper acoustical design.

  2. 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.

This manual is to be used by the roof system erector as a guide for the erection of the UItra-DekŪ roof.  IT IS THE RESPONSIBILITY OF THE ERECTOR TO INSTALL THIS ROOF USING SAFE CONSTRUCTION PRACTICES.  The manufacturer is not responsible for the performance of this roof system if it is not installed in accordance with the instructions shown in this manual.  IF THERE IS A CONFLICT BETWEEN THIS MANUAL AND PROJECT ERECTION DRAWINGS, THE ERECTION DRAWINGS WILL TAKE PRECEDENCE.  If there are any questions regarding proper installation of parts or materials on this roof system, please inquire before proceeding.
