 Both grooved and ungrooved plastic wood composite is made to resist the elements of weather. It implies that if rain or moisture falls on your plastic composite board surface, it will not destroy it. Aside from the rain, the plastic wood composite will resist heat and fluctuating temperature better than timber. 

This infers that plastic wood composite will not crack, warp or split when the temperature becomes too hot. Also, it will not rot or swell as a result of moisture absorption.  Maintaining grooved composite decking is the same as maintaining ungrooved boards. This is because they are both composite boards.

To identify grooved and ungrooved boards, you have to order two samples to feel the boards. Place the plastic wood decking sample you ordered on a table and make it lay flat. Then you should look at the sides of the decking boards. 

Grooved wood composite boards have hollow or channels at their sides. The hollow or inward depression runs from one length of the boards to the other. You can put your hand at the side, and you will feel the hollow of grooved composite boards. 

Note that the hollow is not just on one side of the decking. Both sides of the boards are hollow. The essence of hollows at the composite boards’ side is to hold them down to the joists. The clips that you will use to fix your plastic composite boards will grip the grooved boards at the hollow side. 

Ungrooved Composite Boards

To identify ungrooved composite boards, you should look at the sides of the sample that you bought. If your wood composite boards sides are flat, then without hollow, it is ungrooved. Grooved boards got their name from the caving that their makers did in their sides. 

Unlike grooved boards that require clips for installation, ungrooved boards do not require clips. Decking installers use screws to fix ungrooved plastic composite boards. 

Which Should You Choose?

The kind of plastic wood composite boards that you choose depends on what you want. If you desire a good patio surface finish, then you should install grooved boards. But if you don’t mind the surface finish of your patio, then you can install ungrooved composite boards. 

The advantage grooved plastic wood boards have over ungrooved is that you can use clips and fasteners to install them. Using clips to fix your composite boards will ensure that you have a smooth decking finish. The clips or fasteners will be untraceable. When you walk your patio, you won’t see the clips; every clip will be hidden. 

The clips and faster a will hold down the boards at the grooved or hollow sides. Ungrooved boards don’t have hollows, so if you must install them, you have to use screws. The screws will appear on the surface of your patio after fixing the boards. Although homeowners do conceal the screw by painting them, it will still create an uneven patio surface.

Conclusion

The difference between grooved vs ungrooved composite decking boards is the hollow at the sides. Also, you can fix grooved boards on your patio with clips and fasteners. Ungrooved decking requires screws.
