For further information on environmental issues please contact the sales department of REX Panels & Profiles.
When correctly installed the air leakage of the REX SDW WALL HF 1000 sandwich panels is approx. 2,7 m3/hour/m2 @ 50 pa. Under normal environmental conditions this is tight enough to prevent condensation or unacceptable air leakage. If necessary (i.e. coldstore applications) the airtightness can be improved by gun applied sealing the panel to panel joints using silicon mastic.

The REX SDW WALL HF 1000 sandwich panel is fitted with a soft semi-closed PVC foam sealant. This sealant is factory apllied at one side of the panel (sidelap). With a compression rate of 30% a sufficiently airtight joint will be created.
The REX SDW WALL HF 1000 product is CE marked according EN14509:2013. The quality of our products is under FPC (Factory Production Control) continuesly monitored in our own testlaboratory. These procedures are secured under ISO9001.
The REX SDW WALL HF 1000 panels can be supplied including the following certificates / quality marks:
All products from REX Panels & Profiles come with a standard 10-year product warranty. An extended warranty is available on request under certain conditions. Some coating systems offer an additional (longer) guarantee on the durability of the external and / or internal sheet. For more information or the warranty conditions you can consult the website or contact our sales department.
The REX SDW WALL HF 1000 sandwich panels are stacked interleaved on OSB boards and PS blocks and fully wrapped in foil to create solid and manageable bundles. On request the panels can be stacked with all profiled external sheets up or down.
