Because the use of polycarbonate sheet is still relatively new in Australia, it is understandable that homeowners, architects and builders would have a number of questions about the product. In this article, we have aimed to cover some of the more frequently asked questions that we encounter from those who have no experience with this dot.Gallina product.

  1. What is polycarbonate?
    This is a term that actually describes a polymer, which is composed of many identical units of bisphenol A that have been connected by carbonate linkages in its backbone. It is transformed into the desired shape by melting it and forcing it, under pressure, into a mould or die. The most common these processes is known as extrusion.
  2. What thickness should I use?
    The correct thickness for your polycarbonate sheet will depend entirely on your application and loading requirements. The width, length and structure of the sheet can all impact load and bending capabilities, so it is difficult for us to give a blanket response to this question. You will need to refer to loading charts or contact us to discuss your project.
  3. Does polycarbonate yellow?
    One of the biggest concerns of any person looking to use this sheet somewhere around their home or business is that the surface will yellow due to weathering. The good news is that these products have all been UV-coated on at least one side to prevent the sun from damaging or discolouring the surface. A 10 year warranty is also offered.
  4. How do I clean the sheets?
    After installation, the sheets should be washed thoroughly (using a mild detergent and lukewarm water solution) with a clean sponge or soft cloth and then rinsed with clean water. Paint, grease and smeared glazes can be removed before drying by rubbing at the spill gently with isopropyl alcohol. This can be followed up with a thorough wash and rinse.
  5. How do I cut the sheets?
    If you need to cut through your polycarbonate sheet, you will find that a circular saw with a plywood blade or a jigsaw with a fine tooth blade will produce a clean, even cut. Thinner panels can also be cut with a utility knife, using a clamp and secured straight edge for an accurate line. Always leave the film on until you are ready to install.
  6. Is condensation a problem?
    Whilst polycarbonate can develop condensation as a result of many different environmental factors, this will not affect the performance of the sheets. The effects are purely visual and are, normally, temporary. When handling, transporting and installing this product, care should be taken to minimise the amount of moisture entering the channels.

 

We hope that we have answered your most pressing questions in the article above, but if we haven’t do not hesitate to contact your polycarbonate sheet supplier. They will also be able to provide more information on all of the areas covered above, including the correct sheet thickness for your particular application and detailed instructions on how to clean polycarbonate.
