All property developments require a fencing solution that is attractive, durable and low maintenance. Here, John Abernethie of Birkdale looks at why it’s time to switch from traditional to more modern options.
When specifying a fencing system, certain characteristics should be top priorities. Firstly: aesthetics. A visually attractive fencing solution will make a major contribution to the look and feel of a garden as well as the property’s overall appeal.
The next is strength and resilience. As the effects of climate change accelerate, the UK is regularly experiencing strong winds as well as periods of heavy rainfall – it is crucial that a fencing system is equipped to deal with this.
Finally, a solution that is easy to install will help to ensure high-quality results. A fence that can be erected quickly and without significant labour, will also help to reduce associated costs. So, how do traditional fencing materials deliver in these areas?
FENCE POSTS
Traditionally there have been two key options to select from – concrete and timber. Timber is often viewed as the most visually pleasing thanks to its natural aesthetic. However, timber falls short when it comes to strength and durability due to timber treatments which stop being effective against rot.
Once a fence is installed, timber posts often react with the moisture in the soil and begin to rot at the base. The whole fencing structure will weaken, and become unable to withstand a strong gust of wind. Often this means timber posts are replaced every five to 10 years.
With this in mind many look to concrete instead. Although this might be considered an unattractive and bulky solution that can take a long time to transport and install, concrete is undoubtedly a stronger and more durable option than timber. However, concrete still has other disadvantages.
The material is prone to chipping and hairline cracks that allow water ingress. This will eventually lead to the concrete post failing. Furthermore, from a sustainability perspective, concrete is incredibly damaging. In fact, cement, the key ingredient in concrete, is responsible for 4-8% of total global CO2 emissions. Then, at the end of its working life, concrete has to be sent to landfill.
Thankfully, there are modern solutions that can harness the benefits of both timber and concrete – with none of the drawbacks. Galvanised steel is around 80% lighter than concrete, meaning an 8 ft post weighs just 7 kg. Conversely, a concrete post of the same size weighs about 50 kg. As such, more galvanised steel posts can be transported to site in one van load – and safely installed with ease. This also enables the installation process to be faster, which ultimately lowers the overall cost of a project.
Housebuilders that specify galvanised steel can also rest assured that they are not compromising on strength. Many steel fence post solutions have been tested to withstand wind speeds of up to 110 mph. Furthermore, on top of the galvanising process these posts are often powder coated which improves the aesthetics and adds to the weather resistance of the steel, meaning it will not deteriorate, rot, split warp, crack or chip over time – offering the ultimate ‘fit and forget’ solution.
What’s more, due to its impressive strength-to-weight ratio, galvanised steel solutions come in slim and unobtrusive profiles helping to achieve a subtle look. They can also be powder coated to match almost any garden design and recycled at the end of their working life.
FENCE PANELS
Once a post has been selected, a panel must be specified. As with timber posts, timber panels have always been popular due to aesthetics, yet they carry the same performance flaws.
Composite panels are an excellent and lightweight alternative. They are hardwearing, durable and can recreate the look of timber. As they are also resistant to UV rays, insects and mould, meaning that composite panels will retain their appearance long-term and with zero maintenance.
In addition, they are available in a range of colours providing real design flexibility. It is also worthwhile selecting panels made from recycled materials or material by-products to ensure that they are the most sustainable option.
Together, composite panels and galvanised steel posts can offer housebuilders a holistic and modern fencing solution that will enhance a property’s aesthetic, reduce environmental impact, and help to minimise overall project costs.
