Abstract
The disclosure relates to building construction flashing materials that are presented in both liquid and solid form and is useful in new building construction as well as retrofit procedures. The liquid form is comprised of a silicone base which has been reformulated to improve its flowability and self-leveling qualities allowing it to be applied by brush, pump or spray apparatus. It can be used alone or it can serve as a complementary effective moisture barrier when used with the solid form of the elastomeric flashing materials. The solid form of the elastomeric flashing materials can be extruded sheet material, formed specialty accessories, and/or a readily formable metallic substrate material which has been completely coated with the reformulated liquid silicone, resulting in a highly bendable, formable and shape retaining flashing component. Both the liquid and solid forms serve as an effective moisture guard which can be used individually or together to protect a wide range of building constructions and keep building interiors dry.
