The Institute of Applied Science and Technology has invested in an extrusion and injection line that produces roof shingles from virgin or recycled plastic resins and waste agricultural fibers.
Plastic composite materials are used in prefabricated, portable, and modular buildings. They can also be used for interior and exterior construction projects such as:
- Exterior cladding and wall panels
- Roofs and Ceilings
- Decks and floor tiles
- Windows and Doors
- Crown mouldings and baseboards
- Bath and shower enclosures and sinks
The mixture is extruded with a parallel twin screw extruder to form a homogenous melt strand that is converted to pellets.
The pelletized material is heated until it is sufficiently fluid to allow for pressure injection into the shingle mold where it solidifies quickly.
- Less costly and a lower maintenance alternative to more expensive roofing styles e.g. asphalt, clay etc.
- Lighter than conventional clay or concrete tiles and can be installed over standard roof structures
- Can be made from recycled materials like plastic bottles and natrual waste fibers (sawdust, bagasse).
- Projected to provide a long-lifetime roof (based on material property assumptions).
