Fypon Polyurethane Millwork Product Information
Basic Information:
  • All Fypon items are available for purchase, however not all are featured on the website. Use the Quick Quote page to get a price on any item and/or place an order, or request a Fypon catalog.

  • Benefits of Fypon urethane millwork products:
      1. Moisture Resistant:
        Urethane millwork's closed cell structure prevents water penetration and absorption.
      2. Splinter Resistant:
        Urethane millwork does not splinter like wood. If surface blemishes occur during installation, they can be easily repaired with ordinary plastic wood fiber.
      3. Insect Resistant:
        Urethane millwork provides a practical alternative if you want the look of real wood detailing for your projects, but live in an area that is prone to insect infestation.

  • Fypon millwork should be used for decorative purposes only, not to provide structural support (except Structural Columns, Balustrade Systems and Porch Posts).

  • Fypon should never be installed with mechanical fasteners only. For best results always use non-corrosive fasteners along with urethane base PL Premium Adhesive.

  • Fypon millwork is easy to repair. Use wood filler or automotive filler to quickly fill dents or gashes of any size. Broken moulding can be successfully rejoined with urethane base PL Premium Adhesive.

  • Fypon products should not be stored in extreme heat. Acclimate before installation. Due to urethane's high insulating value, this may take up to 10 hours.

  • Fypon millwork will resist the elements, except for direct sunlight to the yellowish (unpainted) underside of the millwork. It is important to fill damaged or cut surfaces with putty, caulk, and/or paint within a few days. 

  • Fypon urethane millwork can withstand temperatures of about 140 degrees F. However, the millwork should never be placed in an area subject to solar temperature buildup, such as behind a storm door.

  • Fypon decorative millwork can be used safely in accordance with SBCCI, BOCA, CABO and NFPA rulings. There are no official independent laboratory fire test results for Fypon products. The products are equivalent to any decorative urethane products not specifically formulated for fire resistance. 

  • May require altered installation procedures to meet local specifications. Check local building codes.

Installation Instructions:

Using Corrosion-Resistant Fasteners and PL Premium Adhesive
Fypon products should never be installed with mechanical fasteners only. Always use corrosion-resistant mechanical fasteners (nails or screws) AND PL Premium Adhesive when installing Fypon products.

to order PL Premium Adhesive. This combination provides a secure, long lasting bond. Countersink all fasteners about 1/8 inch and fill with exterior grade white spackle. If desired, sand any minor imperfections and topcoat with a quality exterior latex or oil base paint. Fypon exterior millwork installations should be finished using a quality, exterior grade silicone caulk to prevent water infiltration behind siding, windows and doors. Some exterior millwork installations, in particular new construction (before siding is applied) may require a J-channel and/or flashing to prevent water infiltration. Installers must determine which installation technique is best for the specific situation.

Finishing Options:
Moulded of high-density urethane foam, Fypon moulded millwork products have an in-mold barrier coat, which becomes an integral part of the urethane foam as it cures.

After each piece is moulded and trimmed, Fypon applies an exterior grade white primer paint with a built-in ultraviolet stabilizer.

Fypon products are impervious to moisture, so painted surfaces are not subject to the degree of chipping and peeling common with painted wood. Also, they are not subject to decay or insect damage.

Fypon products may be painted with any good quality latex or oil base paint. Usually one coat is all that is needed.

Faux Finishes:
Fypon products are also suitable for many faux finishing techniques, including sponging, feathering, and antiquing using either oil base or latex paints.

White Color Match - Available at Sherwin-Williams:
To better serve customers nationwide, Fypon has worked with Sherwin-Williams to formulate a color and sheen match for the factory-applied finish. You can take this formulation to your local Sherwin Williams dealer for a perfect match:
Formulation: Superior Exterior, Satin Latex
Paint Gallon Base: A89W51
L1 - 1/64
WI - 6 oz.
NI - 1/128
Y3 - 1/128
R1 or R4 - 1/64

Fypon millwork products that are noted as woodgrain / stainable may be stained. Apply a good quality, non-penetrating stain (ZAR, Olympic Overcoat, etc) with a 2" natural bristle brush. Begin applying stain in a circular motion, then feather the stain in the direction of the grain. For a darker finish, apply a heavy coat of stain with light pressure. For a light finish, apply a thin coat of stain with more pressure.
