IsoTop
IsoTop Product Sheet
Features and Benefits
• Ideal for industrial membrane roofs, special construction
• Spans up to 10.0 m are possible
• Reduced load onto the roof substructure
• Direct load transfer into the supporting structure of the building
• Object planning by using individual structural analysis software
• Improved connection details
• Optimization and minimization of the number of roof penetration points
Areas of Application
Membrane roofs of industrial buildings are usually made of a substructure with
large grid spans (5 to 8 meters) and a relatively soft roof covering. Both the
structural dimensioning of the roofs and the maximum allowable load are so low
that fastening solar modules is often thought to be impossible.
IsoTop is the solution for supporting photovoltaic mounting structures on low
load membrane roofs of industrial buildings. The standard IsoTop unit assembly
system works with most industrial roofs, yet can be completely customized for
individual solutions. In the initial stages, Schletter provides consulting for the
planning of the photovoltaic support in order to determine the most economic
solution. Usually, the design constructions are performed with only a few
penetration points required. These penetration points can be welded by a
professional roofer reliably and inexpensively, clearly separating the areas of
liability.
• For individual planning, Schletter uses a proprietary structural analysis
program, offering solutions quickly and inexpensively.
• A complete series of proprietary designs can be applied to almost any
mounting situation.
• As a qualified vendor of standard solar fastening technology with
experience in the metal construction sector and welding licences according
to local standards, Schletter stands by it’s quality products and excellent
customer service.
Structural Dimensioning Suggestions
Solutions involving additional loads are not possible because neither the roof
structure nor the roof covering can bear additional loads. With IsoTop, the roof
covering receives little or no additional loading. Regardless, thorough structural
analysis must be performed to ensure that the substructure can bear the weight of
the mounting rack and the PV modules, plus any external loads (wind, snow, etc).

Supporting Structure
In most cases, steel girders are not necessary because of Schletter’s wide range of load distribution beams available.
Aluminum is preferable for use in the supporting structure in order to reduce the weight of the mounting system. Furthermore,
all components are compatible with each other. Please review the System Overview brochure, available on the web at www.
schletter.ca.
The module bearing rails can be clamped individually and are equipped with Schletter’s proven Klicksystem.
The system components are then inter-connected with customized devices.

Project Planning Examples
In order to offer the most efficient system and
thereby the most economic alternative, Schletter
always asks for the desired module arrangement.
Given complete information, the Schletter
Engineering Team can create a very cost-effective
solution. Use this example (right) to help focus
your expenditure of time on the focal points,
The basic information needed for your planning
can also to be found on the internet (http://www.
schletter.ca). Here data such as location, building
height and further details can be entered.
In some instances, as with wider spans, when
determining specific load applications or unique
construction considerations, a diagram or
illustration might be necessary. By giving our
engineers an illustration (right), in addition to the
IsoTop check list, you can reduce the cost and time
of planning your solar mounting project.
