Alderon is made from uPVC material that is re-formulated and re-engineered to enhance the structural performance of the customary uPVC material, making it outperforms the regular uPVC roofing products in the market.
uPVC stands for unplasticized polyvinyl chloride. Generally, what people know is PVC. So, what is the difference between PVC and uPVC? There are several variances of PVC, but only two types of PVC that are mostly used in everyday life, ie plasticized PVC and unplasticized PVC.
The plasticized PVC is made by adding a plasticizer additive in its production process to make it flexible or easily bent, example for this type of PVC is the hose, the electric cable, shoe sole, etc.
uPVC in contrary, there is no plasticizer additive is added in the making of it. As a result, the product made from uPVC is rigid, and doesn’t flex, products usually made from this type of PVC are window frames, doors, fascia, claddings, roofing, etc.
Unlike metal roof, Alderon won’t rust, it also doesn’t give as much noise as metal roof in case any rain. Alderon also reduces the heat from outside, so you can save your air condition cost, saving your time and money as you don’t have to install the heat insulation foil below your roof.
Compared to the single play roofing, the two plays (twin walls) Alderon is much more rigid, the purlins space in Alderon installation can reach up to 1200mm, it will save your structure cost as well as your installation time.
These twinwall structure also help reduce the heat and sound from outside. For more information, please click here.
Alderon is formulated to be installed outdoors. The lifespan of the Alderon however, can also be affected by how it is installed, where it is installed (eg: the sea side usually has a more severe weather condition), and its surrounding environment such as pollution, winds, etc.
Alderon is warrantied for 15 years.
Yes, made to order lengths are available, subject to minimum order quantity.
Predrilling the holes will prevent the possible damage or wrapping on the panel caused by simply nailing the panel into place. Predrilling also ensures some space allocation for the expansion and contraction due to the temperature changes.
Alderon is strong and rigid enough to bear your weight. However, for a safety reason, walking on a roof during the installation is not recommended. Please ensure that you step only on the structure. A use of a crawl board is also very much recommended.
Alderon is practically maintenance free. Alderon unique formula keeps its surface smooth and easily cleanse the dirt away by simply hosing it with water. In case any dirt remains, gently wipe off with a soft cloth. Please do not use brush or sharp instrument as they might scratch the sheet.
Alderon Twinwall is a uPVC roof that provides a cool environment solution for your house. Currently, Alderon comes in 4 natural color variants; white (doff), blue (doff), white translucent and blue translucent. With its natural color, Alderon Twinwall does not absorb heat.
Why does Alderon Twinwall currently only come up with natural colors? Because by using natural colors, the uPVC roof does not need to use a A.S.A (Acrylonitrile Styrene Acrylate) layer. A.S.A layer is a thermoplastic layer developed as an alternative to acrylonitrile butadiene styrene.
On uPVC roofing products, A.S.A is only used by uPVC roofs that are light-colored, because light-colored roofs are easy to absorb light so A.S.A coating is used as a heat reducer from sunlight. Alderon Twinwall, although not using the A.S.A coating, remains as a cool environment solution for your house.
