Lumber, Building Materials Product Overview


Installation should be in accordance with accepted industry standards and local building codes. Remember to caulk all butt joints, intersections and ends of PVC trims, where applicable.

Weather Resistance

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. We strongly recommend that only light colored tints be used. Dark colors are unable to reflect ultraviolet rays and may adversely affect their long-term performance.

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. products are generally lower in cost than aluminum and zinc products and will be competitive with most galvanized products. All products are available from regional warehouses which supply your local wholesale distributor.


A short form CSI specification appears on each product page; a product description is included to assist you in the proper selection. A copy of the ASTM standard specification, if applicable 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. If cut, the product can be repaired with vinyl cement.

Caulking: Caulking materials bond very well to PVC products. Contact the caulk manufacturer or PLASTIC COMPONENTS, INC. for specific recommendations.

Painting: No special preparation necessary. We recommend Ultra-Tech® elastomeric sealant.
