Abstract
An underlayment material has a fiber mat partially infused and/or coated with asphalt and coated with silicone coating. A selvedge edge, may be coated or uncoated. The back of the underlayment has a self-adhesive coating, which is protected before use by a siliconized release film. The upper surface of the underlayment is coated with silicone composition providing waterproofing and radiation control. When unsaturated, the selvedge edge of fibrous material establishes a reinforced bond with an overlying sheet. When saturated with asphalt, the bond at the selvedge edge between adjacent sheets is between the asphalt layer of the selvedge edge and the adhesive on the bottom of the adjacent sheet.
Claims34
A method for making a building material, comprising the steps of:
- providing a web of support material in a roll;
- withdrawing the support material from the roll;
- coating the support material with a silicone material;
- curing the silicone material to a non-tacky condition;
- winding the coated support material on a take-up roll.
A building material with an upper surface and a lower surface, comprising
- a support web at least partially infused with asphalt;
- a layer of silicone material applied to at least one of the support web or the asphalt, covering at least a portion of the upper surface and defining a selvedge edge on the upper surface that is not covered by the silicone material.
