Vents Product Overview
Vents can be applied to ULTRA-LATH PLUS® plastic lath, metal lath, wood base sheathing products, expanded polystyrene, gypsum sheathing, cement sheathing products and any other code-approved substrate. They are designed to allow a proper free flow of air, reducing the build-up of uncirculated air in attics or areas that do not have air handling systems. Consult product sheets for air flow guides.
Installation should be in accordance with accepted industry standards and local building codes. Connector clips are included.
Ultraviolet Sunlight: Plasticizers and similar chemicals which can migrate to the surface are not present in the PVC formulas used in the manufacturing of PLASTIC COMPONENTS, INC. products covered in this section.
Low Temperatures: All materials will gradually harden as temperatures change. PVC compounds used by PLASTIC COMPONENTS, INC. are formulated to withstand these changes.
Coefficient of Expansion and Contraction: PVC products are weaker than the materials to which they are attached and the plaster in which they are embedded. PLASTIC COMPONENTS, INC. products are designed with perforated flanges and “eyebrows” which provide positive bonding of stucco to the product and substrates to which they are attached. They become part of the building and will move with the wall, subsequently they are not free to express their coefficient of expansion or contraction.
Availability & Cost
PLASTIC COMPONENTS, INC. vents are generally lower in cost than aluminum and are competitive with most galvanized products. All products are available from regional warehouses which supply your local wholesale distributor.
A short form CSI specification is printed on each product sheet and a product description is included to assist you in the proper selection. A copy of the ASTM standard specification is available upon request.
Use SPEC WIZARD® to create complete specification in just a few minutes.
PVC products have a built in resistance to damage and will return to their original shape when subjected to normal impact. There is no transmission of shock, which means damage is localized to the point of impact. Repairs can be made by returning the product to its original shape and reapplying finish to the damaged area.
Caulking: Use a high grade acrylic based product with a fine tip nozzle. Do not clog holes
Painting: No special preparation necessary.
Material Description: All products are manufactured from PVC compounds conforming to ASTM D1784-97, cell classification 13244C.
