Decking_Comparison_table_copy_1

The above table shows the properties and benefits of a selection of different decking options available. To summarise:

  • If you are looking for a decking board with high water resistance, then PVC, or Aluminium Decking, is the best option.
  • If you need a low-maintenance deck that is also environmentally friendly, then consider Composite Decking for your project.
  • For a low initial cost with that real wood look, then a pressure treated Timber Deck is going to be your best option.

1. Cost of the decking material

Choosing the best decking materials will depend on your budget as well as how long, or how often, you intend on using the deck. It's important to think of price and cost as two separate things, with the latter referring to how much the deck costs over its lifetime. Price refers to the initial outlay, so you should consider which additional decking materials to include when buying. This will include additional items such as starter clips, screws, joists and finishing touches. Do you need End Caps for Hollow Core Decking, or Bullnose and Fascia Trims for raised decks and 'picture-framing' an area?

Timber will be cheaper on the initial outlay but will require ongoing maintenance, such as annual staining or treatment, increasing the lifetime cost with the possibility of having to replace Boards depending on annual weather conditions.

Cladco Composite Decking and  Cladco Nordeck PVC Decking have10 and 20 year warranty, respectively, and require low-level maintenance to keep costs down over their lifespan. Aluminium Boards are ultra low maintenance but are more expensive on the initial outlay.

2. Durability of the decking material

With increased durability comes an increase in the initial price, as well as longevity, of the deck. Nordeck PVC Decking features a PVC core that is capped in a hard-wearing, water-resistant ASA-resin shell. This is best suited for areas prone to water, such as around pools or larger water features.

Composite Decking is manufactured from recycled hardwood fibres and recycled plastic and offers low-slip properties, or a high-quality woodgrain effect, with excellent durability underfoot. This is perfect for garden transformations, or covering over unsightly concrete, for example.

Opting for Aluminium provides additional benefits that include fire ratings for balconies and high-rise building projects to meet building regulations. As a highly durable material, Aluminium Decking could be the best option for commercial projects, for example, where durability is number one priority.

3. Maintenance of the decking material

Decking materials of any kind will require some extent of maintenance. A pressure-treated wood deck is more demanding every year to keep it looking at its best, with a Composite and PVC Deck only requiring the occasional wash, whenever needed. Depending on the surrounding conditions, and the location of the deck space, for example, under a leafy tree or by a bush with berries, you may need to invest in a Composite Deck cleaner or a pressure washer.

As is the case with anything subjected to seasonal changes throughout the year, Composite Decking may need some extra care and attention over PVC Decking. For example, due to the natural fibres in Composite Boards, expansion and contraction will naturally occur. Timber Decking will be the most demanding and costly, with staining and treatment being a requirement to keep your deck looking as good as the day you bought it.

4. Environmental impact of the decking material

The environmental credentials of decking materials are important. Cladco Composite Decking is manufactured from 100% recycled materials, comprising of 60% FSC-certified recycled hardwood fibres and 40% recycled plastic, making for an environmentally-friendly product that supports sustainable foresty and reduces plastic waste.

Timber Decking that is preserved with chemical-based preservatives can be damaging to the environment if applied incorrectly, or not properly monitored and maintained. PVC Decks are completely man-made, so have a higher environmental impact than other types of decking materials.

5. Toxicity of the decking material

It's important to know what's in your deck boards and how they've been treated. When opting for Timber Decking, which have naturally occurring oils and natural tannins by default, treatment through staining and painting can affect the deck's toxicity level and may not be the right material for your environment.

Composite Decks are manufactured from recycled natural wood fibres and recycled plastics, which have been combined using glues, tints and dyes to form the colour across a solid form. Once combined, unlike treated wood, a Composite Deck does not require varnishing or sealing to keep it looking new.

Thermowood is pressure-treated wood that is free from chemicals. Unlike other wood decks which are preserved using chemical processes, Thermowood is a non-toxic deck material.

6. Decking Use

A few factors will come into play when considering different types of decking. Cladco Domestic Grade Composite Decking is designed for outdoor spaces that experience lighter footfall and smaller pieces of furniture. The hollow, five-hole honeycomb core forms the centre of these Boards, reducing overall weight for installation and also the price per Board.

Cladco Solid Core Commercial Grade Decking is best for busier deck spaces that will be subjected to greater footfall, heavier furniture and ornaments. Improved soundproofing underfoot is an additional benefit of this type of decking.

PVC Decking, as opposed to Composite Decking, or traditional wood, does not contain any natural wood fibres, and so has improved water resistance, making it best for use around pools, water features, or in areas which are prone to standing water.

Decking options...

234_1

Wood Decking

Traditional wood decking materials come in the form of softwood, hardwood and Thermowood (heat-treated softwood). Pressure-treated wood is where natural wood is impregnated with preservatives and chemicals to give it a longer lifespan, which has its benefits in an outdoor setting.

Softwood

Softwood Timber Decking is made from a common decking material, such as spruce, pine, larch, redwood and cedar types, and is known for being durable and lightweight. Softwoods range greatly in softness, and a common misconception is that all softwoods are softer than hardwoods, which isn't necessarily the case. For example, balsa is a hardwood but is the softest wood in the world.

Cladco Timber Decking is manufactured from softwood spruce and is green pressure treated with preservatives, making this ideal for use in the construction of Decking areas.

Pros

  • Cheap initial purchase price
  • Easy to work with and install
  • Real wood textures

Cons

  • Susceptible to rot and mould
  • Can splinter or crack
  • Requires regular maintenance

Cost per m2

Softwood Decking costs approximately £22 per square metre (£6.70 per square foot).

Hardwood

Typical hardwood decking materials include oak, walnut, ash, beech and maple, to name just a few. Usually, from climatic conditions including temperate and tropical, hardwoods are commonly used in the construction of furniture, flooring and higher-quality, timber-based products that are naturally resistant. Picked for its long-lasting qualities, a deck design featuring these types of decking materials will usually outlast softwood decks.

Pros       

  • Natural timber grain
  • Strong, high tensile strength
  • Increased resistance to rotting

Cons       

  • Ongoing maintenance required
  • Harder to install and heavier
  • A more expensive form of timber

Cost per m2

The price of hardwood decking per square metre can range vastly depending on the type of timber. Expect to pay between £25-£50 per square metre (£7.50-£15 per square foot).

Thermowood

FAQs

What is the cheapest decking material?

Timber decks are the cheapest to purchase on the initial outlay, but with more maintenance required throughout the lifetime of the Boards, this will increase long-term overall costs. A Composite Deck and PVC Deck require little maintenance which keeps long term costs to a minimum.

What is the longest lasting decking material?

The longest lasting deck from the above mentioned deck types is Aluminum. This is a deck type that offers the best resistance to fire, moisture, insect damage and rot, and can last a lifetime.

What is the best low maintenance decking material?

The low maintenance requirements of Aluminum Decking make this type of deck the easiest to maintain, followed closely by PVC Decking. An annual visual check is all that is required to ensure that debris is removed from the surface of the deck. A Composite Deck is also low-maintenance but may require a specific Composite Deck cleaner to remove a tough stain or mark. A timber deck requires a visual check every few months to keep on top of debris and objects, such as plant pots, affecting the wood.

What is the most cost effective decking material?

Composite Boards offer the best short-term value with 10 year warranty. However, if you plan on keeping your Decking area for longer, then Nordeck PVC Decking should be the Decking Board of choice, with 20-year warranty. This averages overall as cheaper per year when compared to real wood or treated wood. If you require a decking space to last a lifetime, then the winner is Aluminium, however, more expensive on the initial outlay.
