The Schletter SingleFix-V Solo Kit is a direct fastening system for self-supporting trapezoidal sheet metal roofs and sandwich panel roofs, allowing Solo mounting rails to be fixed straight onto the roof's raised ribs without penetrating through to the roof substructure below.
This avoids the risk of condensation and thermal bridging that can occur when fasteners pass through sandwich panel roofing into the structure beneath, while still providing a fast, low-part-count fixing method for both portrait and landscape module layouts.

Key Features
No Fixing Into Roof Substructure
SingleFix-V clamps directly onto the raised rib of the trapezoidal or sandwich panel roof sheet, avoiding the need to fasten through to the structure below and reducing the risk of condensation at the fixing point.
Portrait & Landscape Mounting
Modules can be mounted in portrait or landscape orientation, with landscape achieved by clamping on the short edge of the panel.
Kit Includes Fixing Screws
This kit comes complete with 2 x SingleFix-V Solo fastening elements and 4 x self-tapping screws, so no separate screw order is needed for this pair.
Quick, Low-Storage Installation
Designed to be quick to install with minimal storage space required on site compared with bulkier substructure-fixing alternatives.
Angled Screw Installation for Load Transfer
Manufacturer guidance recommends driving the self-tapping screws slightly inclined from top to bottom, pulling the rail firmly onto the roof crown so pressure loads transfer correctly.
Minimum Sheet Thickness Requirements
Requires a minimum sheet thickness of 0.5mm for steel or 0.8mm for aluminium trapezoidal roofing to meet the system's technical approval for screw fixing.
Installation Guidance
Schletter's structural verification of SingleFix-V fastening forces for a given trapezoidal roof is project-specific and should be confirmed through the site's Schletter system design, particularly for roof edge zones and maximum snow load conditions. Screws should be driven slightly inclined from top to bottom to correctly pull the rail onto the roof crown.

Frequently Asked Questions
Does this kit include the fixing screws?
Yes, this kit includes 2 x SingleFix-V Solo fastening elements together with 4 x self-tapping screws, so no separate screw purchase is needed for this pair.
Does SingleFix-V require fixing into the roof's structural substructure?
No. It clamps directly onto the raised rib of the trapezoidal or sandwich panel roof sheet, avoiding the need to penetrate through to the substructure below.
What roof sheet thickness does this system require?
A minimum of 0.5mm for steel trapezoidal sheet, or 0.8mm for aluminium trapezoidal sheet, to meet the system's technical screw approval.
Can modules be mounted in both portrait and landscape orientation?
Yes, both orientations are supported; landscape mounting is achieved by clamping on the short edge of the panel.
Do I need a separate structural calculation for my roof?
Yes. Verification of the SingleFix-V fastening forces for your specific trapezoidal roof should be confirmed through Schletter's site-specific system design, particularly regarding roof edge areas and maximum snow load.
