INSTALLATION ONTO A RIGID SURFACE
If mounting your panel(s) onto a rigid surface such as a RV roof, you will need to take into
consideration the thermal expansion and contraction of both the panel, the surface it’s being
mounted to and the product used to adhere the two together. It is unlikely both the panel and surface
will expand and contract at the same rate, therefore an adhesive with some ‘give’ will be required to
absorb the difference.
UNSUITABLE Adhesive Products
SUITABLE Adhesive Products
Polyurethane adhesives (i.e. Sikaflex)
MS Polymer (i.e. Fix15)
Vented Gap Kit*
VHB (Very High Bond) double sided
tape
Silicone based adhesives (i.e. SG20, Fix8)
Bi-adhesive backing
*Exotronic has designed and recommends the Vented Gap Kit as the preferred installation method.
This method not only allows for thermal expansion but also allows for air flow between the panel and
mounting surface which keeps the temperature of both lower; increasing panel efficiency and
protecting the mounting surface from heat related damage.
You will also need to consider if the mounting surface is suitable for the purpose.
UNSUITABLE Mounting Surfaces
SUITABLE Mounting Surface:
(using an approved mounting method)
Twin-wall polycarbonate sheet
Corflute
High Density Polyethylene (HDPE,
Kingboard®, Seaboard®, Boatboard®,
etc.)
Any other surface that is unstable,
damaged, or may be damaged by high
temperatures, mechanical stress or
trapped moisture.
Twin-wall polycarbonate strips (as in our
Vented Gap Kit)
VHB Tape
Aluminium
Steel
Sealed Marine Plywood
Fibre-glass
Checker-plate*
*Refer to Method 4 for Checker-plate.
