  2. Educational Information

    What are Fypon products made of?
    PVC
    A man-made product created by carefully mixing resins, stabilizers, fortifiers, pigments, impact modifiers and ultraviolet inhibitors in an extrusion process. A blowing agent is added to the vigrin PVC, along with some reclaimed virgin PVC, to create PVC foam. Cellular PVC foam is a thermoplastic material, which means there is a definite melting range normally associated with the base resin in the matrix.
    Urethane
    Polyurethane foam is a polymer consisting of a chain of organic units joined by urethane links. This is a thermoset material, meaning that once the reaction has taken place to form the polymer, it can't be converted back to its original components. Due to this fact, polyurethane foam will not melt at extreme temperatures.
    Is polyurethane some type of polystyrene foam?
    No. The durable Fypon products are high-density polyurethane products, unlike the soft nature of polystyrene foam products. Urethane has the look and feel of wood.
    How are Fypon products made?
    PVC
    Made by adding a blowing agent to the polyvinyl chloride to create a closed cell structure. The combining process differences are what make the PVC competitive materials differ. Unlike other extruders, Fypon blends their own formulation of resin, stabilizers, impact modifiers, and ultraviolet radiation inhibitors. This ensures Fypon has the highest quality of PVC foam.
    Urethane
    Mainly, isocyanate and resin are mixed to create urethane. This is a thermogenic reaction. The compounds foam and expand. The urethane is kept under pressure in a mold as it expands to any desired shape.
    Will these products melt in high temperatures?
    All products, including wood and steel, will melt if the temperature is hot enough. However, Fypon products will not melt under normal use conditions. We recommend following all Fypon painting instructions to ensure top performance of the product.
    PVC
    Extreme temperatures can take a toll on PVC trim, potentially leading to expansion and contraction of products. Special consideration should be given throughout the duration of installation. Areas susceptible to solar temperature buildup, such as behind storm doors, should always be avoided when installing PVC trim.
    Urethane
    These mouldings are somewhat temperature sensitive, as are all organic materials. We recommend over-cutting decorative mouldings by 1/4" per 10' of length (spring fitting the moulding as tightly as possible).
    What styles of PVC and urethane are there?
    PVC
    Fypon offers smooth and woodgrain PVC plus interlocking bead boards and corner boards in sealed or non-sealed edges as well as PVC trim profiles.
    Urethane
    Our polyurethane decorative millwork and trim deliver the beautiful, authentic details and rich textures of finely finished wood, rugged timber, and classic stone accents.
    What are its best uses for the building industry?
    Fypon products are the perfect material for homeowners exterior or interior trim. They are a lightweight material that is easy to work with. Its closed cell structure resists water absorption. this helps prevent the material from splitting, flaking, chipping, or bloating.
    PVC
    Free foam PVC has a solid, consistent structure from surface through the core. This characteristic makes it perfect for fabrication and field cuts. Sealing the cut edge is not necessary to protect the product. In addition, this process also prohibits mushrooming of the product when secured with screws, unlike the celuka process. The free foam process also cuts smooth where the celuka PVC can chip when cut.
    Urethane
    Due to the ability to mold the material, decorative trims with detailed designs are easy to produce. Large moulding profiles can be made out of one piece of urethane, instead of layering wood to create the same look. This saves on labor and time.
    How do PVC and urethane compare?
    Urethane and PVC complement each other and can be easily used together. They both have similar performance benefits in that they won't split, chip, or flake. The quality is consistent from piece to piece and standard woodworking tools may be used for installation with both urethane and PVC.
    Urethane, due to the moulding process, is better suited for detailed, decorative trim and complicated shapes. PVC is suited for straight lengths of trim, milling and using close to the building grade.
    How does PVC compare to composite trim and condensed fiber trim?
    Both material types have similar expansion and contraction considerations and both may be painted. However, composite and condensed fiber trim manufacturers recommend only butt joints. This prevents concealing of gaps to accommodate material expansion.
    Composite and condensed fiber trim will lose their water resistance when trimmed in the field and the product will swell or bloat, even if installed correctly. Any routed details must be primed and painted.
    Even though the cost may be less for composite trims, the performance is less than desirable and can cost more in the long run.
    How does urethane compare to polypropylene?
    Urethane has an authentic wood appearance and can be moulded to resemble actual wood grain. Once the product is stained, it is difficult to tell if it is wood or urethane. Polypropylene has a finish that gives it a slight shine and usually is not solid through the piece. Polypropylene is also a thermoplastic polymer and can warp with intense heat.
    How do I prevent UV fading/deterioration?
    UV rays to not affect properly finished product. Please see Product Usage and Finishing below for the type of product that you are purchasing to be certain you are finishing your product to specifications.
  3. Installation Information

    What type of skills are needed to install Fypon urethane products?
    None. If you can install wood products, you can easily install Fypon products. They can be nailed, cut and sanded just like wood products.
    Are special supplies needed to install polyurethane products?
    PVC
    Fypon recommends noncorrosive fasteners and proper application of PVC compatible adhesive is imperative throughout installation.
    Urethane
    Yes. We recommend using noncorrosive fasteners along with polyurethane compatible adhesive. The adhesive is recommended to place between decorative moulding joints and to secure the fypon piece to the wall along with mechanical fasteners.
    What are some general tips about installing urethane products:
    PVC
    Is relatively fast and easy to install. To ensure smooth operations when installing PVC trim, it is imperative to have construction adhesive and fasteners on hand. Fypon recommends noncorrosive fasteners. The joints between boards and sheets can easily be bonded with PVC compatible adhesive to prevent separation of joints.
    Urethane
    Never install products with fasteners only. For best results, always use noncorrosive fasteners along with polyurethane compatible adhesive on the back and at all decorative moulding joints.
    What type of weather conditions are necessary to install exterior Fypon products?
    PVC
    Since PVC boards expand and contract with the weather, no predrilling or countersinking is necessary if the trim is installed when the temperature is over 40 degrees Fahrenheit. For conditions under 40 degrees, predrill and countersink prior to fastening or the board may split.
    Urethane
    For exterior applications, urethane products can be installed in any temperature, hot or cold, and in any kind of weather.
    Anything special I should know about storing Fypon products?
    PVC
    It is recommended to store on a flat, level surface. Like some soft woods, the product tends to conform to the surface on which it is stored for long periods of time at mid to high temperatures.
    Urethane
    These products can be stored either inside or outside, but not in extreme heat. Products should be stored as it is intended to be installed. For optimum use, polyurethane compatible adhesive should be stored at room temperature until ready to use. Acclimate urethane products before installation up to 10 hours.
    How can Fypon products be cut and fabricated?
    PVC
    PVC trim by Fypon can be ripped to size with a table saw or circular saw using a blade designed for wood or plastic. Shaped edges can be machined with a hand router. No special equipment or saws required.
    Urethane
    In many cases, we can alter one or more standard parts that closely match your requirements to create a part that fits your project specifications. If your project requires a shape, size or profile that you do not see, we have the design and production capabilities to turn your sketch and dimensions into almost any millwork or trim product imaginable.
    How difficult is it to maintain and repair PVC once it's installed?
    Not difficult at all. PVC is considered a low maintenance product and its surface can be easily cleaned with soap and water. If PVC gets a minor nick, scratch or dent in it, repair can be done easily with Bond & Fill™ epoxy.
    What are the recommended fastening procedures for urethane and PVC?
    Please see installation instructions on our website for part specific recommended fastening procedures. Note that products should never be installed with fasteners that are susceptible to corrosion, and that proper use of glue and adhesives is crucial to correct installation.
    What if I use another fastening procedure for urethane and PVC?
    Fypon products must be installed to our recommendations, including use/type of adhesive and fasteners, or the limited warranty will be void. See your Fypon seller or our warranty page for complete limited warranty details and exceptions.
    Is there a recommended procedure for site damage repair?
    PVC
    Structural PVC parts should not be repaired due to the possibility of reducing the load carrying abilities of the part. Non-structural parts can be glued with cellular PVC bonding adhesive and minor blemishes can be filled with PVC compatible acrylic urethane sealant.
    Urethane
    Damaged parts can be repaired using a variety of PUR compatible adhesives, sealants, and fillers. Sand repaired area, prime, and paint to finish.
