Waterproof Roof Membranes
BG PLAST is one of the technology leaders in the production of waterproof polymer roofing membranes for waterproofing flat roofs. In particular, offers complete lines for the production of TPO membranes, which are currently the most advanced solutions of this type on the roofing market.
Waterproof roofing membranes are made of various materials and methods. The most modern roofing membranes include membranes made on the basis of synthetic and natural rubber as well as on the basis of plastics. Membranes of this type are among the most technologically advanced and require the most complex production methods.
Roof membranes have a multi-layer structure and subsequent layers are made of other materials and have different functions: insulating, vapor permeable, reinforcing, UV protection, heat reflecting, adhesive, etc.
The production of the roof membrane is carried out by unrolling subsequent layers and joining in the lamination process. The layers can also be made by extrusion coating or standard coating.
TPO/FPO (Thermoplastic Polyolefin / Flexible Polypropylene Olefin) roofing membranes are membranes made by combining synthetic rubber (TPO thermoplastic elastomer) with PP polypropylene. These membranes can be additionally reinforced with a layer of non-woven fabric or mesh and have additional functional layers.
The advantages of TPO membranes include:
- exceptional resistance to weather conditions
- high flexibility also at low temperatures
- high tensile strength
- high resistance to constant exposure to low and high temperatures
- resistance to UV radiation
- resistance to root overgrowth and microorganisms
- high strength
- aging resistance
- high vapor permeability
Depending on the type of processed material and the application of the line, BG PLAST uses various extruders (single- screw, counter-rotating twin-screw and co-rotating twin-screw extruders) and coating and calendering technologies. BG PLAST’s offer includes three- and four-roller calenders in various configurations (horizontal, diagonal and vertical), as well as special solutions.
