Innovative PVCu extrusions
and creator of the Liniar brand


As the HL Plastics factory is located in the heart of the UK, it can deliver products all over the country using its own transport. Being British made, the carbon footprint of a Liniar window is significantly lower than many of its competitors whose factories are located abroad.

The Liniar products themselves are all made using 100% lead-free PVCu materials, which are better for the environment. PVCu windows can also use less energy to produce in the factory, in comparison to both aluminium and timber windows.

Furthermore, the ongoing energy savings to homeowners installing Liniar’s multi-chambered thermally efficient window and door products are higher, with more PVCu windows achieving BFRC ‘A’ ratings than other materials.

A PVCu window is 100% recyclable and can be recycled up to 10 times, giving each window an estimated life span of 350 years – more eco-friendly than depleting timber sources. A Liniar window is also easier to recycle than other brands, due to the reduction in steel reinforcement built into the frames during the manufacturing process.

HL Plastics recycles all its waste PVCu and has developed its plastic piling range specifically to utilise the recycled material. These products are used in construction and therefore do not need to look as ‘virgin’ clean as the window products, whilst still constructed in lead-free uPVC.

The Liniar piling range itself is extremely eco-friendly as it does not rot or rust, and can be used safely in rivers, streams and bogs with no risk of leaching chemicals into the water. Surprisingly strong, the Liniar plastic piling is very lightweight to carry to site – which is why it is used extensively by bodies such as the National Trust and Environment Agency.
