How should Danpal products be cut?
A circular saw or a jigsaw with a fine-tooth blade will produce a clean, even cut. Angle grinders or hand tools may also be used.
How should Danpal products be cleaned?
To clean small areas, rinse the sheet with lukewarm water. Wash the sheets with a solution of mild soap or household detergent and lukewarm water, using a soft cloth or a sponge in one direction only to loosen any dirt and grime. Rinse with cold water and dry with a soft cloth in one direction only to prevent water spotting. To clean large areas, clean surface with a high-pressure water and/or steam cleaner. (No more than 80 degrees Celsius). Recommended solvent cleaners are: White Spirit, Petroleum Ether (BP65), Hexane and Heptane.
What is the minimum roof pitch for Danpal products?
All Danpal polycarbonate roof systems are intended to be installed at a pitch no less than 5 degrees. This increases the potential for panels to be cleaned by rainfall. It also minimises the risk of water ponding and moisture ingress into the cells of the panels. Contact Danpal for project-specific advice if a slope of 5 degrees can’t be achieved.
What lengths are available for Danpal products?
All panels are locally stocked up to 12 metres in length and can be produced in longer lengths where needed.
What UV protection do Danpal products offer?
All Danpal polycarbonate products inherently block 99.9% of harmful UV radiation that causes skin cancer. Our panels are accredited with 99.9% UVR Protection and 50+ Protection Factor (UPF Rating) by ARPANSA. Options to reduce solar radiation transfer vary according to selected panel types.
Our systems are compliant with the requirements of AS1562-3 without requiring safety mesh.
What is the life expectancy of Danpal products?
Danpal polycarbonate products have an unmatched proven history over 3 decades of use throughout Australia. Independent laboratory has verified that the high UV protection layer co-extruded into Danpal products remains intact after at least 25 years of natural weather exposure.
What sealants should be used with Danpal products?
Non acetic sealants (specifically labelled as compatible with polycarbonate) are generally acceptable for use with Danpal polycarbonate products, but it is strongly advised to check compatibility before use. Care should be taken not to use Amine nor Benzamid curing silicone sealants because these are not compatible with polycarbonate and can result in cracking, particularly when stress is involved.
Is there a problem with condensation in the panels?
Danpal products have specially designed aluminium framing to allow adequate natural ventilation that prevents air-borne water vapour or moisture in cells being trapped and turning to mould. These systems work best when systems are installed at no less than 5 degrees. Panels can be specially heat sealed or supplied in non-cellular form if adequate roof slope is not feasible. Contact Danpal for project-specific advice in these cases.
