Dome Solar, a specialist in photovoltaic mounting for large roofs, stands out from other photovoltaic installers due to its innovative heat-welded systems for flat roofs.
The advantage of these systems is that they allow photovoltaic panels to be mounted on flat roofs without ballasting.
There are two heat-welding systems depending on the type of membrane:
- Bitumen membrane by flame welding.
- Synthetic membranes (PVC and TPO) by hot air welding.
Each of them requires the intervention of a professional weatherproofer.
For a bitumen flat roof
The system is comprised of a set of rails: 1 rail and 2 retaining strips that are pre-mounted on the rail using 2 flanges.
The 4 installation steps are:
- Grid marked on the roof using a string or a laser based on the plans provided by Dome Solar;
- Marking in crayon of the precise location of the rails;
- The shiny surface of the membrane is heated so that the slate flakes melt down and penetrate into the bitumen;
- Positioning of the rail and flame welding of the two retaining strips.
These 4 steps are a mandatory protocol for the correct installation of Roof-Solar Bitumen and Roof-Solar Tilted Bitumen systems.
For a PVC or TPO synthetic flat roof
The set of rails is hot air welded.
The 4 installation steps are:
- Grid marked on the roof using a string or a laser based on the plans provided by Dome Solar;
- Marking in crayon of the precise location of the rails;
- Positioning of the rail and hot air welding of the two retaining strips;
- Tack welding of reinforcing patches in the corner of the rails.
These 4 steps are a mandatory protocol for the correct installation of Roof-Solar PVC, Roof-Solar Tilted PVC, Roof-Solar TPO and Roof-Solar Tilted TPO mounting systems.
This technique, which does not require any ballasting, has the advantage of limiting the weight to be borne by your roof.
