Carlisle 705 Air & Vapor Barrier is a 40-mil-thick (0.040″ inch) composite membrane consisting of a rubberized-asphalt adhesive laminated to a tough, dimensionally stable, smooth-surfaced poly film. Carlisle 705 Air & Vapor Barrier is provided in rolls of various widths lined with disposable silicone-coated plastic release film. The release film is removed to expose the adhesive as the membrane is pressed in place. 705 provides a complete barrier to moisture and air when adhered to an above-grade substrate. Cut sizes are also useful for other above-grade wall flashing applications. CCW-705 is cold applied and will adhere firmly when pressed against the substrate. Questions? Contact Us.
CCW-705 is designed for use in above-grade wall assemblies to function as an air, vapor and water barrier. CCW-705 can be applied over many common building materials including gypsum sheathing, concrete masonry unit (CMU), concrete, wood, structural steel, metal flashings, aluminum extrusions and rigid PVC (i.e. pipe/conduit, window frames). All substrates shall be prepared with a CCW contact adhesive to provide consistent adhesion of CCW-705 in jobsite conditions.
Standard installation of the product can be performed at when ambient and substrate temperatures are 40°F and above. Installation below 40°F, as low at 25°F, can be performed if the product is stored in a heated area until use and the laps are treated with CCW contact adhesive. Installations below 40°F are best addressed with CCW-705 XLT – low temperature adhesive formula. Consult the CCW-705 XLT product data sheet for further instruction. Install CCW-705 in horizontal rows or in vertical runs. Wipe dust or debris from film side of product with a clean, dry rag to assist in forming tight laps. Avoid forming wrinkles and air pockets. Press membrane firmly to substrate with a hand roller, especially at laps, corners and terminations. Overlap adjoining pieces of CCW-705 a minimum of 2 inches. Use narrower cut sizes for detailing. Sequence the installation to provide shingled laps. Membrane shall bear minimum 3 inches onto each side of transitions such as joints, angle changes and substrate changes. Membrane shall bear 6 inches minimum onto adjacent membrane systems such as foundation waterproofing or roofing. Apply a 1″ width X 40 mil thickness ribbon or Barribond or LM 800 XL over to field-cut edges, T-joints, reverse laps and terminations. After CCW-705 installation, Pressure-Sensitive Elastoform may be used to detail expansion joints and window/wall transitions. Consult CCW-705 details for more information.
