Joining polycarbonate sheets is a critical component to roofing success. The use of high-density roofing materials has increased dramatically in recent years. In response, roofing manufacturers have come up with multiple-ply roofing systems that offer greater strength and durability. Unfortunately, these multi-ply roofing products also have lower cost-efficiency.
When compared to traditional composite roofing systems, joining polycarbonate sheets requires significantly less materials. The material that you would need to make the roofing materials is a blend of high-density polycarbonate (HDP), low-density polycarbonate (LDP), and UV protection. This formulation provides an excellent solution for both joint flexibility and reliability. In fact, it is often said that HDP roofing materials are easier to repair and replace.
When joining polycarbonate sheets, it is important to use only galvanized tape. Galvanized tape does not bond with the surface of the polycarbonate. It does not guarantee the strength of the roofing system. Also, if you are not satisfied with the performance of your polycarbonate roofing system, it is not possible to have the panels replaced by the manufacturer.
It is also important to install only one uPVC anti-ultraviolet barrier before joining the polycarbonate sheets. The number of layers on the anti-ultraviolet barrier will depend on the amount of sunlight exposure your roof gets. For instance, if you live in a place that experiences a lot of sun, then you may consider two or more layers of anti-ultraviolet barrier. However, it should be noted that uPVC’s effectiveness is reduced at higher temperatures. Hence, the first layer of anti-ultraviolet barrier should be applied when installing your roofing system.
When fastening the polycarbonate sheets together, make sure that you use the right screws. Choose stainless steel screws for better performance and long-lasting durability. Also, ensure that you use the fasteners that are designed for roofing installations. See to it that you secure all the pieces of the sheet using the right fasteners.
There are basically three types of roofing systems using polycarbonate sheeting. These are the single-side, full-length, and half-length systems. A single-sided system consists of one side of the polycarbonate roof sheeting joined to a plywood frame using traditional screw installation. Full-length systems require two sides to be joined using threads on each side and an additional fastener called the twinwall screw. Lastly, the half-length system employs overlapping seams between the polycarbonate panels.
In order to reduce the moisture that develops in the roofing, you can also opt for moisture barriers that cover the polycarbonate sheets. These are often available in plastic or glass forms. This way, even if condensation or water accumulates on the roofing, it would still be trapped within the barrier before reaching the interior chamber of the roofing system.
For those concerned about the effects of ultraviolet light, there are UV-resistant polycarbonate sheets. This kind of material contains substances that block the ultraviolet rays. The ultraviolet rays cannot penetrate through the surface into the sheet materials. Moreover, UV-resistant systems are more durable than other varieties of anti-ultraviolet barrier.
While polycarbonate sheets are strong and durable, they also have a tendency to sag after exposure to high temperatures. This phenomenon is called creep along. To prevent this from happening, manufacturers make use of corrugated sheet metal. Corrugated sheet metal’s surface is hinged at its top so that it can be bolted to the roofing materials. Additionally, the metal is easily cut with saw blades or drills.
When fastening cellular polycarbonate sheets together, special tools are required in order to avoid chipping the sheet. One of these tools is the flat head screw gun. This tool allows fastening of corrugated sheets without using nails or screws.
Glazing, as well as polycarbonate sheets, are fitted into roofing shingles through adhesives called nylocs. Nylocs are typically water-based adhesives, which dry quickly and provide a firm grip for installation. To ensure that the roofing installation is successful, the installation company also uses roofing felt, which has a waffle texture, to fill in any voids before putting the roofing material on the roof.
After the polycarbonate sheet and the roofing materials have been fitted and sealed, the roofing is placed on top of the polycarbonate sheet. The entire procedure requires a great amount of care from the roofing contractor. The roofing company must work inside the building to install the glazing and corrugated sheet so that there are no obstacles during the installation. If anything should go wrong during the installation, the company can call upon the services of a qualified roofing repair specialist to assist them.
