Wood Composite Decking includes four major disadvantages

While wood composite decking has several advantages over traditional wood decking, it also has some drawbacks. You must evaluate the disadvantages of wood composite decking and how they will affect you in the long and short term while choosing the finest outdoor decking material for your project.

The strength of wood composite decking

The strength of wood composite decking

Wood composite deck boards are heavier than typical wood deck planks and offer less strength. Their lack of strength causes them to droop and bow. Builders must use wood for the understructure and framework since composite decking cannot be employed as a load-bearing or structural product. For posts, beams, joists, and stair stringers, you’ll need to buy typical wood. If you choose composite decking for environmental concerns, keep in mind that your deck will still be supported by pressure-treated wood.

Hot Decking

Hot Decking

Homeowners frequently express their dissatisfaction with the temperature of their wood composite decks. When exposed to direct sunshine, komposittrall absorbs and retains heat. It might take hours for the boards to cool down enough for you to walk on them without shoes. Burning Deck boards not only hinder you from completely enjoying your investment but also put children and pets in danger. If you’re concerned about surface temperature, go for the coolest material available in the lightest hues.

Expansion and contraction cause damage.

Due to temperature changes, composite decking expands and contracts rapidly. It really travels further and in more unpredictable ways than typical wood. The boards may break, delaminate, and peel as they expand and shrink. Your decking may shrink, warp, twist, and bend as a result of the movement. Damaged composite decking caused by expansion and contraction will almost certainly need to be replaced right immediately.

Mold Susceptibility

Mold Susceptibility

Although composite decking firms advertise their products as “mold-resistant,” they nevertheless include wood. Wood rots and molds when exposed to dampness. The organic materials in uncapped wood composite boards are exposed to the elements because they lack a protective coating. Mold can permeate the exposed area of capped wood composite boards since they are only enclosed on three sides. Although fully encased composite deck boards provide better protection, moisture can still get into the boards through the skin’s perforations. Mold can form on the surface of composite decking or inside the boards if they get wet, especially in the shade where the boards do not have enough time to dry off.
