Thermoplastic Advantage
One of the properties of thermoplastics is that the material temporarily changes from a solid to a semi-solid state when heated sufficiently, enabling the sheets or panels that are overlapped to be fused together and return to a solid upon cooling. When completed, the welded seam becomes one monolithic layer of material impervious to moisture infiltration and as strong as the membrane itself. The hot-air welded seam is the most secure seaming method available and will not deteriorate even in the presence of moisture, temperature or stress.
