Most Common Questions Asked When Starting a Decking Project

We are in prime decking season and many are craving an outdoor space to call their own. Though the industry is navigating through labor shortages and soaring material prices, the desire to create an outdoor living space is on the rise. We gets hundreds of calls from dealers everyday who have a customer ready to buy a TimberTech® deck or rail package, but many questions come up. We’ve compiled a list of the most common questions we get from dealers when putting an order together. We have been able to supply material for thousands of decking projects and we get many of the same questions. So, we’ve created a guide to outline some key tips to help you during your process.

TimberTech Railing

First, let’s dive into railing. It’s common that ordering railing for a deck can feel complex and difficult, and we want to change that. Here are some of the most common questions our team receives about railing:

What is the difference between a universal rail pack versus a custom rail pack for the Classic Composite Series?

A universal rail pack has predrilled holes for composite balusters. A custom rail pack does not have predrilled holes. It will have laser etching on rails, and can be used with aluminum, glass, or cable railing.

What is included in the universal/custom rail pack?        

Top and bottom support rail, hardware, and foot blocks. The designed top rails (Premier Rail, RadianceRail, Trademark Rail, and Reserve Rail) are not included in the rail packs – they are now a separate SKU. Remember to purchase your balusters!

What are RadianceRail Express® Rail pack options?

RadianceRail Express can be ordered in the 4 easy steps shown here. We’d like to point out that with RadianceRail Express, composite balusters are for regular rail packs and are not noted for aluminum balusters. For aluminum balusters, you will want to make sure you are ordering the rail packs noted for aluminum balusters.

How many balusters are needed per rail section?

Composite Balusters come 18/pack.

  • For 6’ section – 13 balusters are needed.
  • For 8’ section – 18 balusters are needed.
  • For 10’ section – 23 balusters are needed.

Aluminum Balusters come 20/pack.

  • For 6’ section – 15 balusters are needed.
  • For 8’ section – 20 balusters are needed.
  • For 10’ section – 25 balusters are needed.

Cover existing 4×4 posts with these post sleeves:

  • 4”x4”x39” Post Sleeve (For 36” level rail height)
    • White-AZT4X4PCV39W
    • Black-AZT4X4PCV39B
    • Kona-AZT4X4PCV39K
  • 4”x4”x96” Post Sleeve (Cut to Custom Post Heights for all applications)
    • White-AZT4X4PCV96W
    • Black-AZT4X4PCV96B
    • Kona-AZT4X4PCV96KAZEK

Please note that a 6×6 sleeve will fit over a 6×6 post, not a 4×4.

How do the aluminum balusters attach to the rail? Screw or plug?

The following come with screws to install your balusters into the support rails: RadianceRail®, Premier Rail®, Trademark, and Reserve.

Builder Rail comes with plugs and connectors to install to the top and bottom rail that the balusters will fit snug into.

When and where do I use a taller post for 36” rail heights?

You will use taller posts at the bottom of the stair sections, and you can always cut down if it ends up being too tall. When ordering stair sections, request taller balusters (ie: 36” height would need 31” balusters; aluminum will state stair in the description where composite does not.)

Decking Accessories

We receive many requests for accessory items TimberTech has available. You can view all current accessory items here.

  • When using a pneumatic flooring nailer, AZEK suggests using barbed/serrated 2″ stainless steel cleat “T” nails or “L” cleats.

Lighting

Deck lighting adds so much to the ambiance of a deck, we don’t want questions or uncertainty to get in the way of adding it to your next decking project.

What light wattage is used in each part of the deck and rail:
  • Post Cap: 4-watts
  • Island Cap, Accent, Under Rail, and Stair Riser: 2-watts
  • In-Deck: 1-watt
  • Optional dimmer with remote for use with a 100-watt transformer: 20-watts
  • You can opt to use the transformer with 90-watts, or the 150-watt PowerPack with built-in dimmer, timer, and dusk-sensing photo-eye. You can use up to 40-watts per circuit and 90-watts per transformer.
