Plastic PVC Decking vs Timber Decking.

Life's Simplicity


Generally people enjoy lifestyle simplicity. Taking the dog on a long walk and spending time with friends and family. To do this effectively, and providing the UK weather permits, this includes spending time outdoors in the fresh air, maybe in the garden, on the decking, terrace area or balcony. 


Unfortunately the outdoor lifestyle here in the UK is minimal to say the least, lets face it...it rain a lot, more than we want. This rain, the wind, the sun and for the more extreme, snow and frost are all elements out of our control that often take their toll on traditional timber decking materials, causing rot, warping, twisting, splitting, fading that all put together can create a very unsightly dangerous and slippery surface. It's fact that traditional timber decks require serious and regular maintenance. Instead of enjoying your free time, you're outside maintaining your timber decking, maybe re-painting, re-varnishing, replacing old warped pieces with new pieces, and on top of all that then you have the drying time to be able to use it again. Your valuable free time has disappeared...


So what do you do? Look for an 'upgrade' maybe look to an alternate to wood decking, maybe composite PVC planks...plastic and again not eco friendly. You may soon realise you've made another mistake. Why? Well, aside from the obvious discolouration, given time, PVC can also be extremely slippery and dangerous, more so than timber decking. It's made of plastic, and therefore generally looks and feels like plastic. Lastly, it's longevity of wear and tear is questionable at times.


The answer? Well if you've done your homework you may have come across a fibre cement decking board variant, these are far more durable, a long lasting decking material that can still give you the look and feel of real wood, fibre cement decking will not burn, it's anti-slip, will not twist, split or warp and has longevity with a minimum of 25 years. You've found the perfect decking material.


Realistic and natural looking

Fibre cement decking boards are made in a press mold to give the texture of real wood giving it a realistic looking wood finish. Whilst most composite PVC decking manufacturers also claim the same, the presence of plastic inside the decking also means that the finished deck planks have a very 'distinctive' plastic sheen to them, letting everyone know exactly what your deck is made of, before they even set foot on it.


Unlike composite PVC decking, fibre cement isn’t stamped or pressed from a larger sheet and contains NO plastics giving it great looks and a natural warm feel similar to that of real wood.


Natural wood has its pluses aesthetically however given time, and when left open to the elements it fades in colour, it's surface treatment coat peels or wears off giving added maintenance whereas with fibre cement you can just fix it into position and leave it, it's totally maintenance free.


Durability, standing the test of time

In a time where everything around us is increasing in cost your decided purchase needs to stand the test of time, this should still apply to your choice of decking. Fibre cement decking can certainly offer longevity allowing you a minimum of 25 years of normal wear and tear, certainly in many cases you should want your decking to last as long as you own your home, fibre cement decking provides this longevity. Given the nature of cement, the boards themselves are extremely durable allowing the boards to be used for the majority of structural projects. Fibre cement construction boards are resistant to insects, resistant to moisture, UV stable - some may say, it's got it's factor 50 on. Fibre cement decking is naturally flame resistant and classed as a non-combustible, BBQ on your decking to your hearts content with no worry of fire or damage. Your fibre cement decking can be safely used all year round without the need to worry about putting on any protective coats, sealants and insecticides that are usual for timber treatment on a yearly basis.


Installs Easily

A controversial topic, who knew about that 'extra' box of fasteners and clips? It's too late when you've made your mind up "Don't worry they're spares"...Composite PVC decking is complicated, the amount of clips and fasteners is extensive, this really slows down the installation creating the possibility of you needing to find a tradesman, and quick, to finish the work on your behalf. Fibre cement decking on the other hand installs quickly and easily with no hidden extras, and if you have ever put together a timber deck before you will easily make the switch to fibre cement and won’t be slowed down in the slightest.

The purpose of this article is to educate and provide evidence-based resources to the UK market on the comparison of MgO and Fibre Cement. We will compare key factors such as price, fire safety, water resistance, and focus on durability, a crucial factor often overlooked. We will examine construction industry practices to highlight potential issues with MgO, enabling you to make an informed decision. Risks of MG0 Boards? To start this article is best to dive into the deep end. As of April 2020, NHBC (National House-Building Council) announced "NHBC will not accept MgO building boards on buildings where the foundations are begun on or after 30 April 2020 under its insurance warranty" and "Where MgO building boards have already been, and are currently being, installed on buildings, you should use an alternative product if it is practical to do so." - Reference: https://www.nhbc.co.uk/builders/products-and-services/techzone/technical-updates Alongside NHBC, the LABC announced "LABC Warranty no longer accept the use of all types of Magnesium Oxide board (MgO) on any of our structural warranty schemes." 15 days earlier. - Reference: https://www.labcwarranty.co.uk/technical-blog/updated-guidance-for-magnesium-oxide-boards-mgo Leading render manufacturers have prohibited the use of MgO boards with their renders, as per their "red list, following the withdrawal of LABC, NHBC and their own findings. Why The Discontinuation of MG0 Boards In Construction? The discontinuation of MgO use was prompted by a 2017 study from the Technical University of Denmark that revealed moisture damage issues with magnesium oxide boards."and they begin to leak salty water, which is highly corrosive, and leads to moisture and mould problems in wooden members of the structures." leading onto a repair bill "which has had detrimental consequences, such as an expected cost of repair of around 2 billion DKK." when converting into todays value in GBP the cost is in excess of £300million (three hundred million pounds). - Reference: https://www.sciencedirect.com/science/article/pii/S1876610217349378 Concerns were raised down under, when both School of Science and Engineering and College of Engineering, Australia had "raise questions about the appropriateness of magnesium oxide boards" following their study of hygrothermal performance of magnesium oxide (MgO) boards. - Reference: https://www.sciencedirect.com/science/article/abs/pii/S0950061821021875 Followed by a released finding that shows "Magnesium oxide (MgO) wallboards have been linked to damages reported globally and within Australia. These damages include dampness, cracking, and accelerated corrosion of contacting metal fixtures." - Reference: LINK Effects of MG0 board in Steel Structures?
