Keep Your Composite Decking Dry with Rubber Flanges!

Composite decking dry boards are made from wood fibers, plastic and other materials which make the boards flexible, easy to cut and lighter in weight than traditional lumber boards. Although composite decking makes building a deck much faster and easier, you must take precautions to keep the water from penetrating through the spaces between the composite decking boards. If water seeps underneath the boards, mold can develop, staining and rotting the board making it unsafe to walk on. To prevent this from happening, use rubber flanges on the spaces between each board.

Why Use Flanges?

Composite decking boards are typically made from a combination of wood fibers and plastic. These composite deckings can be an attractive, low-maintenance option for homeowners that don’t want to worry about the upkeep of natural komposittrall massiv. However, this material does have its drawbacks. One is that it absorbs water easily, which means that even small amounts of rain can cause water to seep through the bottom of your deck boards and into your home below.

How to Install Flanges?

How to Install Flanges?

Installing flanges is easy, and only takes a few minutes. There are three different ways to install rubber flanges on your composite decking: 1) measure the distance between deck boards and cut the flange to size; 2) place the rubber flange over the gap between deck boards; 3) measure the distance between deck boards and drill a hole in one end of the flange then push it onto a screw or nail. The screws/nails will hold the flange securely against the decking boards. For easier installation, you can use nylon deck board screws which will not require pre-drilling as they are self-threaded.

What Type of Flange Should I Use?

You may be wondering, What kind of flange should I use? Well, that’s a tough question. There are so many different types of flanges out there. For example: rubber flange, vinyl flange, metal flange, wood and plastic decking boards. On the other hand, if you have a wood deck, or decking boards for that matter, metal or wooden flanges are better options.

Wooden flanges work great for decks made of lumber because they provide an extra level of insulation in addition to keeping water out. Metal flanges work best on decking boards made of metal because metal doesn’t absorb moisture like some woods do (such as cedar). Metal flanges also offer another advantage over wooden ones – they won’t rot over time like wooden ones can when exposed to excessive amounts of moisture in high-humidity environments like decks.

How Many Flanges Do I Need?

How Many Flanges Do I Need?

For a 2’x8′ area, you’ll need 18 flange pieces. For the larger 4’x8′ decking boards, use 24 flange pieces. The size of your deck will determine the amount of rubber flanges you’ll need. If you have a smaller deck or if your deck is only 1-2 feet high, consider using komposittrall pris instead to avoid having to use so many rubber flanges. Wood decking boards are more difficult to waterproof and therefore might require more time and materials when it comes time to replace them.


If you’re looking for a way to protect your new deck, consider using rubber flanges. They’re easy to install and can keep water from seeping underneath your composite decking boards. What are the advantages of having composite decking? One major advantage is that it’s waterproof. Unlike wood decking which is susceptible to water damage and decay, composite decking won’t rot or warp. The gaps between the decking boards allow water to flow easily, so be sure that you fill them with rubber flanges before they cause any problems!
