Which Deck Railing Would You Recommend?

For low cost high quality deck railing, we have two brands that we rely on; aluminum railing from Afco Industries and vinyl railing from Fypon.

Both of these deck railing alternatives come in around the same price, and are a good fit for anyone wanting a long lasting deck railing, without moving up to a polyurethane balustrade system. When choosing between one or the other, there are a few factors to consider.

Fypon Vinyl Railing

Fypon has been manufacturing vinyl railing for many years now and is known for its quality and sturdy construction. One consideration in buying any less expensive vinyl railings is the possibility of fading in direct sunlight, or any brittle behavior brought on by harsh winter climates.

Fypon vinyl railings have been tested over time, installed from Florida to Arizona and New York to Alaska.

Fypons sturdy vinyl deck railings come in two colors; a standard white, or a beige colored railing. Also there is the choice of square or colonial Balusters or pickets, dependent on the look that you are aiming for.

Fypon also sells vinyl porch posts and now supply a white vinyl railing with glass inserts to match.

Afco Industries is probably one of the best known suppliers of aluminum columns and decorative porch and deck railing in the United States. With the majority of components manufactured in their own U.S. plants, you know that you can count on the quality of these decorative, yet sturdy, aluminum railings.

Perhaps one of the greatest attributes in the Afco line, are the seven powder coat finishes available. Few other aluminum railing companies offer as much of an assortment of finishes, never mind the quality that comes from a powder coat application. Powder coating involves a combination of paint finish combined with a heat application that bonds the finish to the aluminum in such a way that Afco is able to offer their extensive warranty on all of their finished aluminum products.

In order to install your deck railing up a staircase, both systems have adjustable railing hardware that can be used at a variety of angles to ease in the installation process.

Afco also supplies handy brackets to mount their aluminum railings to any number of their available aluminum columns. Balusters are available in either square or round design and tend to be thinner than vinyl balusters.

Both systems offer esthetic quality and value to your outdoor stairway, deck or porch area; given the variations of color and appearance, the final decision is up to you.

Why Don’t You Recommend Center Blocks?

Good question; in fact, we don’t even recommend corner blocks for the installation of decorative crown molding.

Traditionally, an installer will typically use corner blocks, when they are not confident in cutting mitered corners for their crown moldings. In fact, if you have an installer that requests that you buy corner blocks, you might want to question what they know about installing crown molding.

There are even some web sites, that will push these blocks as a decorative addition to your crown molding purchase; the greatest addition being to the price.

Some customers in fact, prefer the look of corner blocks in the inside and outside corners, believing they enhance the look; and who are we to say otherwise. But the use of center blocks and the idea of recommending them leaves us scratching our heads.

By its very name, a “center block” needs to be in the center of a wall. So what happens when you order 8 foot mouldings for a 10 foot wall? The answer is, you end up with more waste, as you would end up needing to cut both 8 foot pieces in order to create a center seam to place the center block in the middle of the wall.

Our 8 foot mouldings match in plain designs or with the design, end to end, so there is less concern for the filling of seams. Just use a little bit of wood filler or spackle, sand and touch up with paint, and the seam is gone. Using the 8 foot example, you would run the first piece of moulding along the first 8 feet and then cut off a two foot piece to attach to that. Obviously this isn’t in the center, being the whole reason you’re not using center blocks and saving money by doing so.

Crown molding corner blocks are still very handy for anyone who wants a quick and easy job installing crown molding, but for those who are up to the challenge, there are lots of good videos on YouTube showing many different methods and tricks for installing crown moldings. Additionally, a number of our crown moldings come with precut matching corners; alleviating the need for corner blocks altogether and enhancing the overall look and value of your project upon completion.

Polyurethane Millwork Frequently Asked Questions

How Do I install Polyurethane Mouldings?

Complete instructions for installing polyurethane mouldings and millwork can be found under INSTALLATION on the FAQ page.

How Does The Density of Polyurethane Compare To Wood?

We manufacture the majority of our products with 6 Lb polyurethane foam typical to that which is used by other major polyurethane suppliers of architectural mouldings. If you were to hammer a nail through one of our mouldings, it would be similar to hammering through a piece of soft pine.

How will direct sunlight effect my mouldings.

The mouldings do come with a white primer coating on them that will provide ultraviolet light protection during installation. Many exterior paints now contain some level of protection from the rays of the sun. As with wood, the protection is only as good as the finish that is applied.

How Does Polyurethane Molding and Millwork Compare In Price To Wood Moulding Alternatives?

A basic rule when pricing out Polyurethane Moldings and Millwork is that the larger or more complex the profile is, the more you will save with Polyurethane moldings. Having said this, any application where dampness is a factor, Polyurethane moldings are best, as they do not rot, nor will they require painting as often as wood moldings do.

If pricing is a concern and all that you want is a very simple profile for a dry area of the house, then you may be better off shopping at a local dealer for your profiles; however, if you want something more extravagant then give polyurethane moldings a try.

There is also a huge saving if you are doing a built up profile. Take our 170ED for example. Once installed, this profile will look as though you went around the room three times to install your moldings: once for the top piece of flat stock, once for the bottom piece of flat stock and again for the crown molding in the middle. Since all of these pieces are joined as one, you only pay to install one molding rather than all three. You will benefit by receiving the same look as if you had paid for all of the extra installation, cutting, gluing, nailing and caulking of three profiles.

Will Polyurethane Moulding Increase My Real Estate Value?

When a real estate agent values a home they often look at the extras involved. While kitchens and baths are often an important part of this evaluation, the actual finishing of these and other rooms plays an important part in real estate evaluation. Since polyurethane millwork is usually so decorative and allows for less costly crown molding installation, detailed profiles can be obtained, providing a rich finished look without the need for costs commonly associated with multiple wood moulding profiles or plaster installation.

Crown Molding Frequently Asked Questions

How Does The Room Size & Ceiling Height Determine Which Crown Molding I Should Purchase?

Some people are of the opinion that the height of a ceiling or the size of a room has everything to do with selecting crown moldings; an interior designer may suggest otherwise.

When selecting crown and cornice moldings, it is important not only to imagine what the moldings will look like as part of the room, but what they will do to the overall appearance and transformation of the room. While smaller profiles typically finish a room nicely, larger moldings with different shapes and profiles can change the entire look of the room. Installing a very large cove molding like the 191ED in a room of any size will give the ceiling a rounded appearance at the walls. This application could be used in a large dining room or even a small powder room or bath area; for a less daring approach, a smaller profile like the 104ED or the 103ED would offer a similar effect, while at the same time adding a bit of detail and definition.

Designers seem to be moving away from the idea that the size of a room or height of a wall determines the size of the moldings to be installed. One adage still maintained however, is that the height of the baseboards along the bottom of the wall should be chosen to compliment the size of the moldings above. The larger the crown, the larger the baseboard installed below.

Fire Rating Frequently Asked Questions

Rigid Polyurethane, Architectural Elements and Millwork Flame Spread and Smoke Ratings

Updated February 2017

Crown-Molding.com products have a flame spread rating of less than 75 when tested in accordance with ASTM-E84. This rating meets the requirements of the Residential Universal Building Code for Foamed Plastic Trim.

Moldings manufactured by any number of alternative methods are rarely the focus of fire rating specifications owing to the percentage of the wall that they occupy; however, Crown-Molding.com recommends checking with local building codes if there is any question regarding these requirements.

Upon customer request, Crown-Molding.com fire rating can be upgraded to ensure a “UL”, Class 2 (B) rating*. The capability of the “UL” rated products limits flame spread in the ASTM E-84 tunnel test to only 40 and reduces smoke development to 225-325. These test results are below acceptable levels for most fire coded requirements.

*Please Note:
Additional charges will apply to products being manufactured with a fire resistant rating in excess of regular standards.
Orders for product exceeding regular fire resistant ratings may impact on delivery time.

Molding Installation Frequently Asked Questions

Polyurethane Installation

Polyurethane mouldings may be installed much the same way you would install wood mouldings.

For a better fit, it is advised that a flat or Butt Joint is used to join longer lengths of polyurethane mouldings. Cut all pieces 1/8th of an inch longer than the required measurement, fitting the ends in place first and the middle sections last.

Always place a continuous bead of premium polyurethane adhesive along all adjoining wall and ceiling surfaces before final positioning of the moulding. Poly-glue is essential when attaching one length of moulding to the next. A pneumatic pin nailer works well for fastening polyurethane mouldings to wall and ceiling surfaces; alternatively, trim head drywall screws or finishing nails may be used.

Corner Blocks

Corner or center blocks may be used to avoid difficult or challenging mitre cuts. When using corner or adjoining center blocks, be sure to mount the blocks to the wall and ceiling prior to measuring and cutting moulding lengths.

Filling and Sanding

Once all of the mouldings are fixed in place, fill any joints or remaining voids with a paintable siliconized latex caulking. This same caulking may be applied sparingly along the top and bottom edges of the moulding where it meets the ceiling and wall. A damp cloth or silicone coving tool may be used to clear away any excess caulking to leave a clean professional look.

Any remaining nail or screw holes may be filled with sandable, paintable non-shrinking filler. Be careful not to over sand the surfaces of your polyurethane mouldings. Sanding past the protective barrier undercoating may necessitate further filling and sanding to maintain a paintable surface.

Ceiling Medallions

Place a solid bead of premium adhesive around and about the backside of the medallion. Pressing the medallion into place, it may then be secured with 4 trim head dry wall screws. Be sure to place the screws so that any holes created may be filled and sanded with minimal effort.

Wall Niches

Some surface mount wall niches may be hung temporarily using attached hardware or permanently using the same applicator procedures as for Ceiling Medallions. Other niches available come complete with their own template and installation instructions.
