What Is Capped Composite Decking?

Posted on: October 15, 2015

Imagine starting next spring with a beautiful, new outdoor living space, where you can relax and sip your coffee, entertain friends, and enjoy the changing Maryland seasons. Although outdoor recreation season is drawing to a close for this year, it’s not too early to start planning your new deck for next season. One of the most durable and attractive decking material available is capped composite decking.

New & Improved Composite Decking

Capped composite decking is a more modern (and improved) version of composite decking. This material is made using recycled lumber (from deforestation projects) and plastics like shampoo and detergent bottles. The “cap” refers to a top layer that is fused to the material that adds an extra measure of protection. This helps keep the deck from fading, chipping and/or staining.

The core of the boards is made using a hard, non-organic polymer material. The top layer (or the “cap”) is made with organic, wood polymers that give it the look of real wood with very few of the disadvantages associated with wood decking. You can even get capped composite decking with a grain pattern embossed on the surface.

Advantages of Composite Decking

Capped composite decks are a top choice among Maryland homeowners because they are:

  • Durable. Most composite decking manufacturers offer a warranty for at least 25 years. The average lifespan of a wooden deck is just 10 to 15 years.
  • Low maintenance. Unlike wood decking material, composite decking won’t splinter or peel. It also doesn’t need to be re-sealed or re-painted every year. The only thing you’ll need to do to keep your composite deck looking sharp is to spray it well with a hose periodically.
  • Water-repellent. Wood decks absorb rainwater and melting snow, causing them to rot and warp, while composite decks are impervious to moisture and rain water.
  • Unattractive to insects. Unlike wood decks, composite decking won’t be damaged by insect infestations. Termites and other wood-eating bugs will pass by your composite deck.
  • Made using recycled material. Composite decking is made using mostly recycled material, unlike wooden decks that require trees to be harvested in order to produce it.
