For mounting sandwich panels and flashings, special self-drilling screws with EPDM gasket are used, and after installation is completed properly, they ensure perfect joint tightness. Side and length-wise overlaps of roof sandwich panels with polyurethane core, additionally should be joined by tight rivets or short screws for flashings (“farmer screws”).
Our offer includes self – drilling screws of the following types:
– for steel supports of max. 6mm in thickness (mainly cold-formed steel structures)
– for steel supports of max. 12mm in thickness (hot-rolled steel structures)
– for wooden and concrete supports
– for mounting of flashings and seaming of panel locks (“farmer screws”).

Sealing collar is made from a high-quality EPDM rubber which is resistant to both high temperatures and very low sub-zero temperatures, UV-ozone radiation, abrasion and tear. Flexible base of the collar ensures accurate matching and adhering to the roof surface. It will not break and crush as temperature fluctuates. Protects joint area against leaks.
Our offer includes:
–  collars from Ø60mm to 450mm.
– resistant to weather conditions
– easy to install

material: EPDM rubber (ethylene propylene diene monomer)
Resistance to temperatures: -50°C to 125°C (continuous temperature)
Compressive strength: 10 MPa


Any minor leaks which may cause penetration of any amount of water and contaminations should be protected with an adequate roofing sealant or a special sealing tape included in Izopanel offer. It is particularly useful to apply “plastically stable” sealants when sealing areas of contact between flashing and wall, and length-wise joints on sandwich panels.
Roofing sealant:
– resistant to temperature and its fluctuations;
– resistant to UV radiation;
– aesthetic finishing (flexible), i.e. “cooperating” with surfaces to be applied on
– available in various types
– tight protection of surfaces
– easy application.

Touch-up paints:
– paints resistant to contaminations
– high spreading rate
– wide range of colours
