Birdsmouth / Knee Rail

Our recycled plastic fencing offers a modern, sustainable alternative to traditional timber fencing, combining a classic appearance with exceptional durability. Manufactured from 100% recycled plastic, this maintenance-free plastic wood fencing provides all the visual appeal of timber without the ongoing upkeep. Unlike wood, recycled plastic fencing will not rot, splinter, crack or require painting, staining or preservative treatments, making it an ideal long-term solution for schools, parks, playgrounds and public spaces.

We offer three styles of recycled plastic Birdsmouth / Knee Rail fencing to suit a range of applications and loading requirements.

The Standard design features an 80x80mm cross-bar housed within a 100x100mm post, creating a clean and streamlined appearance. This option is ideal for lower-traffic areas where boundary definition is required, such as separating flowerbeds, landscaped areas and pedestrian pathways.

The Classic design uses both a 100x100mm post and cross-bar, with the rail projecting beyond the face of the post to create a more traditional knee rail appearance. This versatile option is well suited to car parks, parks, green spaces and public realm projects where moderate vehicle and pedestrian traffic is expected.

For more demanding environments, the Strong design incorporates a robust 100x140mm post combined with a 100x100mm cross-bar. Engineered for higher-impact applications, it is ideal for busy car parks, play areas, pathways and other locations that experience frequent daily use and increased traffic levels.

Recycled Plastic Birdsmouth & Knee Rail Fencing

Birdsmouth, also known as Knee Rail fencing, is one of the most popular boundary solutions for parks, public spaces, car parks and landscaped areas. Designed to clearly define boundaries while maintaining an open and welcoming appearance, Birdsmouth fencing provides an attractive alternative to more intrusive fencing systems, helping to guide pedestrians, protect landscaped areas and control vehicle access.

At Second Life Products Wales (SLPW), we manufacture high-quality recycled plastic Birdsmouth and Knee Rail fencing, offering a durable, sustainable alternative to traditional timber fencing. Manufactured in the UK from 100% recycled plastic, our plastic wood fencing combines the timeless appearance of timber with exceptional durability, delivering decades of reliable performance with virtually no maintenance.

Unlike timber, our recycled plastic fencing will not rot, splinter, crack or absorb moisture. There is no need for painting, staining or preservative treatments, making it the ideal solution for local authorities, landscape architects, contractors and commercial developments looking to reduce ongoing maintenance costs.

Designed for Public Spaces

Our recycled plastic Knee Rail fencing is commonly specified where subtle boundary definition is required without obstructing views or creating a physical barrier. It provides an attractive way to separate pedestrian areas, protect landscaping and define vehicle routes while blending naturally into both rural and urban environments.

Typical applications include:

  • Parks and open spaces
  • Public footpaths and cycle routes
  • Car parks
  • Schools and playgrounds
  • Nature reserves
  • Housing developments
  • Commercial landscaping
  • Visitor attractions
  • Highway verge protection
  • Heritage sites

Its traditional appearance complements almost any environment while providing a durable, maintenance-free solution that continues to perform year after year.

Three Styles to Suit Every Application

To ensure every project receives the right level of strength and performance, our Birdsmouth / Knee Rail fencing is available in three standard configurations.

Standard

The Standard design features an 80x80mm cross-rail housed within a 100x100mm post, creating a clean and streamlined appearance. This option is ideal for lower-traffic environments where simple boundary definition is required, including landscaped areas, flowerbeds, pedestrian routes and public gardens.

Classic

Our most popular option, the Classic design uses both a 100x100mm post and cross-rail, allowing the rail to project beyond the post for a more traditional Birdsmouth appearance. Perfect for parks, green spaces, public realm projects and car parks, it provides excellent durability while maintaining an attractive finish.

Strong

For demanding environments, the Strong design incorporates a heavy-duty 100x140mm post combined with a 100x100mm cross-rail, providing increased impact resistance for busy car parks, play areas, pathways and locations that experience regular vehicle movement and heavy public use.

Why Choose Recycled Plastic Instead of Timber?

Traditional timber Knee Rail fencing can deteriorate over time, particularly in damp environments where moisture causes rot, splitting and decay. Regular painting or preservative treatments are often required to maintain both its appearance and structural integrity.

Our recycled plastic Birdsmouth fencing eliminates these problems. Manufactured from 100% recycled plastic, it is resistant to moisture, frost, UV exposure and insect attack, ensuring long-term performance without the need for ongoing maintenance.

The result is a fencing system that not only looks great but also significantly reduces lifetime ownership costs.

A Sustainable Solution for Public Realm Projects

Every metre of our recycled plastic Knee Rail fencing is manufactured using recycled materials, transforming waste plastic into durable infrastructure that supports environmentally responsible construction and landscaping.

Its exceptional lifespan, combined with virtually zero maintenance requirements, makes it an excellent choice for councils, contractors and developers seeking sustainable, long-term solutions for public spaces.
