摘要： Disclosed is a shingle that uses a polyester sheet as a substrate layer. The polyester sheet has a sufficient weight and is needled and formed from two layers to resist shrinking upon cooling after the heated asphalt layers are applied to the polyester substrate sheet 102. In addition, additives may be included in the asphalt to lower the softening point temperature of the asphalt that further reduces shrinking of the polyester substrate 102 or allows other polymers that are more fire retardant to be used. Fire retardants can be placed in the polyester sheet fibers, placed in the bonding agent for the polyester fibers, or the polyester sheet can be coated with the fire retardant. Alternatively, or in addition to treating the polyester sheet 102 with fire retardant, fire retardant materials such as ammonium sulfate can be added to the liquid asphalt prior to application of the asphalt layers.

摘要： A lightweight roofing shingle comprising a saturated mat having an exposed side and an unexposed side wherein a fabric reinforcing layer substantially replaces the bottom asphalt coating and the backing aggregate on the unexposed side of a conventional shingle. The lightweight shingle will have a top asphalt layer applied to the exposed side of the mat and a layer of granular material applied to the top asphalt layer opposite the mat per conventional construction, and the fabric reinforcing layer is adhered directly to the unexposed side of the saturated mat. In one embodiment, the fabric reinforcing layer covers an entire area of the unexposed side of the saturated mat. The reinforcing layer may preferably be a nonwoven fabric made from PET or polypropylene. The lightweight roofing shingle may also include a release tape layer applied to the reinforcing layer opposite the saturated mat.

摘要： Disclosed is a release material that can be applied as a liquid, gel, emulsion, foam, etc. in a shingle manufacturing line. The release material can also be used in the manufacturing of roll roofing. The release material primarily constitutes an emulsion of polymers that can be cured with heat, IR light or other methods. Silicone may also be included in the emulsion which assists in releasability. The release material can be sprayed or extruded on to the surface of the shingle in an automated fashion, eliminating the necessity for operator interaction.
