Reasons to install Liniar decking

Liniar decking systems help to create beautiful, long-lasting and low maintenance decks for holiday homes, lodges, play areas and gardens all over the UK. Manufactured in Derbyshire using high quality composite uPVC, using part-recycled materials, Liniar decking is a sustainable, durable and low maintenance alternative to traditional timber decking systems.

Having been manufacturing decking since 1999, Liniar is Made in Britain – in fact the whole range is designed, modelled, tooled, manufactured, foiled and stocked at Liniar’s state-of-the-art 410,000ft² facility in the heart of the UK.

With a choice of two double-sided deckboards in a range of colours, Liniar offers matching, maintenance-free accessories including the UK’s only fully sculptured balustrade system and a choice of galvanised steel or low aluminium sub-frames. Finished with a wide choice of accessories or lights, the Liniar brand is synonymous with quality engineering, style and innovation. Continued investment in product design and development, facilities and machinery keep Liniar at the forefront of the very latest technology.

For our trade installers, we can deliver to almost anywhere in the UK using Liniar’s own transport – and because most components are available from stock, lead times are kept low, meaning your deck can usually be supplied quickly to site.

Whether it’s for a holiday home, a public area or a garden, you can be assured of a top quality product with Liniar’s unparalleled attention to design and engineering details, together with a great level of customer service – all at a competitive price.

Liniar’s choice of sub-frames means a no-timber decking installation – with nothing to rot or degrade! The original galvanised steel sub-frame creates the ideal base on which to build a deck for the holiday home market, whilst the more recent low aluminium sub-frame is perfect for garden decking areas. Installing deckboards onto a metal sub-frame means a totally rot-free installation and a long-lasting deck to enjoy.

Liniar’s steel sub-frame consists of just two components – an  ‘I’ beam and it’s connector. The sub-frame is connected into a grid pattern and the deckboards are fitted directly to the joists.

The original sub-frame has been further improved by developing a 600mm uPVC sub-frame Nogging and pre-slotting the steel. You can see the significant time saving this has created by watching our comparison video.

Liniar decking systems have been tested for strength by loading a 2m x 2m deck with a total weight of 1,250kg (1.25 tons). This represented a loading of 521kg per square metre.

The load applied was left for two days on three different deck samples, resulting in no signs of bowing, wear or strain on any of the decks – evidence of just how strong the system really is.

The Liniar balustrade system adds an attractive perimeter around your decking area. Each bottom rail is supported by galvanised steel reinforcement, giving a strong, secure balustrade which offers more fire resistance than traditional materials (to Class 1).

Access to raised decking areas isn’t a problem with matching steps and ramps available. Liniar’s ramps are built using the same strong and sturdy sub-frame and deckboards, so they will easily take the weight of a mobility scooter.

Unlike more traditional alternatives, Liniar’s range of uPVC decking doesn’t rot and never requires regular maintenance – simply clean it occasionally with warm soap water.

The uPVC decking system contains waterproofing properties and the decking is manufactured with an slip resistant tread for additional safety; this is particularly important when the surface is wet.

The decking is constructed onto a choice of sub-frame, which offers greater strength and durability than more traditional materials.

Additionally, our uPVC components carry a Class 1 Y fire rating which confirms there will be no surface spread of fire.

Either steps or ramps can be incorporated into most decking designs, providing an attractive, personalised entrance or easy access for those with mobility difficulties.

The low maintenance Liniar range has been carefully crafted, not only to add real value, functionality and style, but also to meet the strictest environmental legislation.

The whole system uses recycled materials wherever possible and is completely lead-free, making it better for the environment and better for you and your family. It’s also fully recyclable at the end of its useful life.

Designed by Liniar’s in-house team, Liniar’s stylish double-sided deckboards offer a great degree of durability and strength. Choose from original 150mm wide SwitchBoard or premium 175mm wide SwitchBoard Ultra – both with an attractive embossed finish and a choice of woodgrain patterned or traditional grooved finishes.

Both styles of SwitchBoard composite PVCu decking have hidden fixings for great aesthetics and safety, just like the balustrade system. As a solid core deckboard, SwitchBoard Ultra can also be face fixed just like a traditional timber deckboard, making installation even easier.

Liniar decking has been tested for slip resistance (BS7679), wear (BS EN660:1999 and BS EN428:1993), with an anti-slip surface, making deckboards safe in both wet and dry conditions.

SwitchBoard decking is available in a choice of five colours – Agate Grey, Anthracite Grey, Natural, Clay and Ivory – whilst SwitchBoard Ultra comes in four premium embossed shades – Shale, Iron, Concrete and Ash.
